Can I use vinegar to clean AC coils?

Yes, vinegar mixed with water is often used to clean AC coils at home. However, vinegar is usually effective only against lighter dirt build-ups. Nevertheless, you can keep your coils in good shape by mixing white vinegar and water in a spray bottle and spraying the mixture onto the coils.

Can you clean an AC coil without removing it?

Use a compressed air canister. One of the best ways to get the dirt and other debris out is to use compressed air. Blow the air into the coil to loosen the dirt. If there’s stubborn dirt, though, you might need to put the nozzle close to the bottom of the debris, along its side.

How do you clean the coils on a Goodman package unit?

Take a vacuum hose with a wet-dry brush and suck up any dirt, dusty grass, and other debris that has accumulated in your air conditioner’s condenser coils. Once you’re done vacuuming, use a garden hose to spray water through the coils. When the water washing through them is clear the coils are cleaned.

Can you use degreaser on AC coils?

However, a mild soap solution or a degreaser is a much better alternative. Each cleaning with a corrosive solution knocks years off the coil life while greatly reducing its efficiency and operating capacity.

Can I use Simple Green to clean my AC evaporator coils?

Use a hose to spray out your AC unit, without spraying the disconnect or the electrical components inside the access panel. Spray the coils down with Simple Green All-Purpose Cleaner. Cover the condenser coils entirely with the cleaner.

Can I use Windex to clean AC coils?

I have used Windex window spray and find it safe and good enough to do the job. By the time I get it sprayed all over the coils it has soaked in enough to clean and I wash it off with the hose. ater you get it clean this time, take the time once a month to rinse it out with a water hose.

What are the symptoms of a dirty evaporator coil?

Symptoms of a Dirty Coil

  • Air Conditioning Loses Cooling Capacity. One thing that will be noticeable when the evaporator coil is dirty is that your AC won’t produce air that’s as cold as it should be.
  • Air Conditioning Runs Longer.
  • Coil Develops Frost During Operation.
  • Have an HVAC Professional Clean Your Coils.
  • How often should AC evaporator coils be cleaned?

    Evaporator coils should be cleaned at least once a year. By keeping them clean, you will also minimize energy usage and reduce utility costs. It is estimated that dirty evaporator and condenser coils can increase the energy usage of your AC system by over 30 percent!

    How do I Clean my indoor air handling unit?

    As long as your system isn’t sealed, you can begin to clean. You need to remove the access panel on your indoor air handling unit. You should be able to see the evaporator coils. If you don’t, refer to your manual to find out where they are.

    How to Clean AC Evaporator Coils

    Avoid overlooking system components that are hidden away within the system cabinet or the air handler enclosure when it comes time for your air conditioner’s regular preventative maintenance checkup.The evaporator coils of the device are one of the additional components that are covered under this warranty.When difficulties arise as a result of clogged evaporator coils, the efficacy of your air conditioner can be reduced, its production can be reduced, and destruction or malfunctions can occur.Some important information about the purpose of an air conditioner and its usefulness as evaporator coils is provided here, as well as some advice on how to clean an air conditioner’s evaporator coils.

    The particular importance of evaporator coils

    The heat from the air within your home is captured by the evaporator coils.Instead, condenser coils disperse captured weather into the air around the outer unit of the air conditioning system.Coils are often composed of copper and are surrounded by a series of aluminum fins, which aid in heat transmission by allowing more air to pass through.The evaporator coils are housed within the interior air handling unit, whilst the condenser coils are housed within the outer cabinet of the air handling unit.

    The evaporator coils in your air conditioning system are critical to the proper operation of the cooling system.They provide the cooling required to generate the chilly air that keeps your house or company comfortable even when the temperatures are at their sweltering highest.Additionally, evaporator coils are essential for the dehumidification services that your air conditioner provides.As the temperature of these coils falls, water condenses on them and is removed from the air within your home.This water is collected in a drain pan until it can be securely discharged somewhere else.When evaporator coils become soiled, their ability to perform these two functions is severely reduced.

    1. Dust, pollen, and other pollutants can be carried away by the air that passes over the coils.
    2. Because these coils are always moist due to the dehumidification process, it is very easy for pollutants to stick to them and cause damage.
    3. The presence of dirty air filters in an air conditioning system (or the absence of filters altogether) might increase the amount of material that comes into contact with the evaporator coil.
    4. Using only a short period of time, it is possible to concentrate enough material on the coils to significantly reduce their performance.

    If evaporator coils and condenser coils get dirty, there can be dilemmas such as:

    • Heat transfer is reduced, cooling capacity is reduced, energy consumption is improved, operating pressures and temperatures are improved, and so on.
    • Increased wear on the system, which can result in component damage, system failures, and shortened system life expectancy.

    A buildup of ice on the coil

    Over the course of the year, you can anticipate that an air conditioner with filthy coils would consume over 40 percent more electricity than one with clean coils. It is possible to reduce cooling capacity by as much as 30% or more. While your air conditioner continues to lose productivity and effectiveness, your electricity costs will continue to soar as a result.

    Basic air conditioner service

    Split-system cooling systems, often known as central air conditioners, are comprised of an inside unit and an outdoor unit, as previously stated.The condenser, condenser coils, and compressor are all located in the outside system.Meanwhile, the interior unit is comprised of the evaporator, evaporator coils, and the air handler, among other components.The evaporator coils are responsible for receiving heat, while the condenser coils are responsible for dispersing it.

    As the refrigerant moves through the system, its condition changes from a liquid to a gas and then back to a liquid depending on where it is in the cycle.During these shifts in land elevation, heat is either consumed or emitted.Cooling is a procedure that has been developed for your residence or place of work.Aeriform refrigerant transports heat, and once it reaches the outside unit, it is compressed by the compressor..The coolant next enters the condenser, where the heat contained within it is released into the surrounding air by the compressor coil, which is located outside the building.During this process, the refrigerant transitions from its gaseous form to its liquid state.

    1. The liquid coolant is then forced to flow into the evaporator, where it eventually turns into a gas.
    2. As this process takes place, the refrigerant absorbs the heat from the air passing past it.
    3. Because of this, the evaporator coil gets extremely cold, matching the temperature of the source of the fresh air that is pumped throughout your house.
    4. The air handler is responsible for circulating air over the cooled evaporator coil.

    As the cold air moves through the coil and into the ducting system, it is distributed throughout the building.It is then delivered into your home through vents and entry located at the extremities of the duct network’s length.In the case of hot exhaust air, return ducts return it to the system, where it is filtered and the cycle is repeated.

    The significance of regular A/C maintenance

    Preventive maintenance is critical to ensuring that your air conditioner continues to operate at peak performance.Maintenance should be performed at least once a year, ideally just before the cooling season begins to kick in.Periodic maintenance should be conducted by a qualified HVAC technician in the majority of serious instances.System experimentation and adjustment, minor repairs and component replacements, air filter replacements, and cleaning of the evaporator, including the condenser coils, are all tasks that have been successfully done.

    The majority of these maintenance tasks, such as changing air filters, should be completed by you.Additional cleaning of the evaporator coils can be accomplished if you have mechanical aptitude.Depending on the type and level of cleaning completed, the following are some useful steps for how to wash air conditioning evaporator coils.These procedures may also be used to clean the compressor coils in the outside cabinet, which can be found here.

    How to clean A/C evaporator coils

    Evaporator coils should be examined on a regular basis and cleaned as needed. If these coils have a proclivity to accumulate dirt and debris fast, it may be necessary to clean them on a monthly basis. Otherwise, you may need to clean them every three months during the colder seasons or once a year during your regularly planned preventative maintenance appointments.

    Clean A/C evaporator coils by getting access.

    Access to the evaporator coil should be provided on the interior air-handling unit through a panel that can be easily removed. If necessary, consult your air conditioning owner’s manual to determine the location of the entry and evaporator coils.

    Air conditioner off at the thermostat.

    Remove the screws or other ties that are holding the entrance panel in place. Place the panel and screws in a location where they will not be misplaced.

    Cleaning the A/C evaporator coils with compressed air:

    Light buildups of dirt and other debris may easily be cleaned by blowing them away from the evaporator coil using compressed air, which is a rather simple procedure.By blowing compressed air over the coil in the opposite direction of usual airflow, from the cleaner side to the dirty side, the coil may be cleaned.Continue to position the air nose near to the bottom side of the trash if it continues to be obstinate.If you’re utilizing high-pressure air, route it either at a 90-degree angle through the fins or directly through the fins to maximize efficiency.

    This will prevent damage to the fins from occurring.Consistent airflow over the coil should be maintained.This will eliminate the accumulation without driving it farther into the fins and making it more difficult to remove in the future.Avoid blowing dust, filth, and debris into your house’s ducting system or into the living areas of your home.Wearing eye protection will help to keep the material out of your eyes.If required, utilize a store vacuum cleaner to collect items while they are being taken from the store.

    Cleaning the A/C evaporator coils with a brush:

    When it comes to eliminating tiny accumulations of dirt from evaporator coils, brush cleaning might be a valuable procedure.Cleaning using a brush permits the use of liquids or other substances.It allows you greater control over the amount of force exerted to the reels and fins on the boat.Make use of the brush to remove dirt mounds away from the coils.

    Break up tougher-to-remove material with the brush as you scrub it away.It is best not to use cable brushes or hard-bristle brushes on the fins since they may cause damage to them.

    Cleaning A/C evaporator coils using industrial cleaners:

    Cleaning evaporator coils may be accomplished with a variety of professional cleansers from well-known manufacturers. The most significant are the foaming types, which degrade and deplete the unit’s drainage system over time. For more information on which cleaning would be most appropriate for your case, contact All Time Air Conditioning.

    How to clean A/C evaporator coils using mild detergents and water:

    Instead of using a commercial cleaner, you may clean the coils with a mild soap and warm water, which is less expensive.In a spray bottle, grip sprayer, or garden sprayer, combine hot water and a mild cleaner until thoroughly mixed.Distribute the liquid and detergent liquid evenly throughout the evaporator coils.Allow for a few moments to a few seconds for the solution to sink in and loosen any particles.

    If necessary, reapply.Brush or wipe away any loose debris with a soft cloth or brush.

    How to clean A/C evaporator coils: heavy-duty cleaning:

    It may be necessary to use powerful chemicals or heavy-duty cleaning procedures on heavily contaminated evaporator coils, which may include the use of equipment such as a force washer or steam cleaner.A/C system modifications may also be required as a result of the procedure, including removal of the coil, cutting and reattaching of refrigerant channels, replenishing the vacuum in the refrigerant channels, and refilling the system with refrigerant (if applicable).A professional cleaning and maintenance appointment with an HVAC expert should be scheduled as soon as your air conditioner’s evaporator coils get substantially soiled or become unclean enough to negatively impact the air conditioner’s performance significantly.It is possible for All Time Air Conditioning to precisely analyze the task, clean your evaporator coil, and restore the cooling system’s operation while inflicting no harm to the coil reels, fins, or other components.

    How do you clean the evaporator coils on a central AC unit?

    To clean the evaporator coils on your air conditioning unit, you’ll need five different tools: a screwdriver, a stiff brush, a big hand mirror, household bleach, and wire.Ensure that you are aware of the location of the evaporator coils once you have obtained these items.The evaporator for a central air system is found in the plenum, which is directly above the furnace and contains the compressor (main duct).It’s possible that the plenum in your air conditioning unit is sealed tight.

    If this is the case, do not attempt to open it; this indicates that you do not have an air conditioner that you can clean yourself.If you are able to access the plenum of your air conditioning unit, the first thing you should do is remove the foil-wrapped insulation that is located at the front of the plenum.This insulation is most likely taped in place, so be careful when removing the tape.You’ll have to take everything apart and put everything back together again.An access plate is located behind the insulation.Remove the screws holding the plate in place using a screwdriver by removing them from the plate.

    1. Remove the access plate after the screws have been removed.
    2. You should now be able to view the evaporator itself.
    3. Some can be slid out a little, even if they contain hard pipes, but you must use caution when doing so.
    4. To clean the underside of the evaporator unit, use a stiff brush and a hand mirror to scrub the surface.

    Cleaning the tray that lies underneath the evaporator will also be necessary at this point.The tray’s purpose is to collect and transport condensation from the evaporator.One spoonful of bleach should be poured into the weep hole to prevent fungal growth from forming.Having a lot of moisture in the tray may indicate that there is an obstruction in the drain line that links the weep hole to the tray.It’s possible to open up the drain line by pushing a wire through it if this is the situation.After you’ve finished cleaning, push the evaporator back into its original position if you’ve relocated it, and screw the access plate back into place.

    The insulation must then be re-taped over the plenum to complete the job.

    How to Clean an Evaporator Coil

    To clean the evaporator coils on your air conditioning unit, you’ll need five tools: a screwdriver, a stiff brush, a big hand mirror, household bleach, and wire, to name a few examples.Make a note of the location of the evaporator coils once you’ve obtained these resources.The evaporator for a central air system is found in the plenum, which is directly above and below the furnace (main duct).Perhaps the plenum in your air conditioning unit is completely sealed.

    Attempting to open it will result in the discovery that you do not have an air conditioning unit that you can clean.First and foremost, assuming that you are able to access the plenum of your air conditioning unit, you should remove the foil-wrapped insulation that is located at the front of the plenum and dispose of it.Due to the possibility of taping, thoroughly remove the tape from around this insulating layer before proceeding.You’ll have to take everything apart and put it back together again after that.An access plate can be found behind the insulation.Remove the screws that are holding the plate in place using your screwdriver.

    1. Remove the access plate once the screws have been removed.
    2. At this point, the actual evaporator should become visible.
    3. If they have stiff pipes, some can be moved slightly out of the way, but proceed with caution.
    4. Cleaning the underside of the evaporator unit with a stiff brush and a hand mirror is recommended.

    Cleaning the tray that lies beneath the evaporator will also be necessary.The tray’s purpose is to collect and transport condensation from the evaporator to a collection container.To prevent fungal development in the weep hole, pour one spoonful of bleach into the hole.An obstruction in the drain line, which links the weep hole to the tray, might be causing a lot of moisture to accumulate in it.It is possible to open up the drain line by inserting a wire through it, if this is the case.Inspect the evaporator for damage and push it back into position if it has been displaced.

    Then screw the access plate back into place.The insulation must then be re-taped over the plenum to complete the installation.

    1. Once the screws have been removed, the access plate should be removed as well.
    2. You should now be able to view the actual evaporator.
    3. If they have stiff pipes, some can be moved slightly out of the way, but be cautious when doing so.
    4. Clean the underside of the evaporator unit with a stiff brush and a hand mirror.

    Cleaning the tray that lies beneath the evaporator is also recommended.The tray’s purpose is to collect and transport condensation generated by the evaporator.Pour one tablespoon of bleach into the weep hole to prevent the formation of fungus.Having a lot of moisture in the tray may indicate that there is a clog in the drain line that runs from the weep hole to the tray.It’s possible to open up the drain line by inserting a wire through it if this is the case.After you’ve finished cleaning, push the evaporator back into its original position if you’ve relocated it, and screw the access plate back in place.

    After that, you must re-tape the insulation over the plenum.

    • 2 Disassemble the air handler unit by removing the access panel. Socket wrenches, nut drivers, and screwdrivers are all useful tools for removing screws and other fasteners from the panel. This includes any tape or reflective metal foil that may have been used to seal the panel edges. Place the panel and screws in a safe place where they will not be misplaced or separated
    • If you are having trouble locating the panel, consult the owner’s handbook for your air conditioning system.

    2. 3Identify the location of the evaporator coils. These are often located on the air intake side of the fan coil or on the output side of the furnace, depending on the model. Coils are often composed of copper, steel, or aluminum, and are comprised of tubes bent into U-shapes and arranged into an A-frame form consisting of two panels on either side. Fins, which are thin bits of metal, are used to line the inside of these panels. Advertisement
    1. Invest in an industrial-sized pump sprayer as well as professional cleaning solution and a brush. The use of a professional-grade alkaline cleaning solution for evaporator coils will release dirt and mold from within the coils, while the spray wand will reach into the unit’s tiny areas and the bench brush will grasp and hook debris from within the unit. Pump sprayers should be between 1 US gal (3.8 L) and 2.5 US gal (9.5 L) in capacity and be brand new, as old pump sprayers may have been used to spray poisons such as weed killer or pesticide on crops.
    2. Routine cleaning and moderately soiled coils may be accomplished using 1 US gal (3.8 L) sprayers, whereas severe cleaning is best accomplished with bigger sprayers
    • Spray the coils with the cleaning solution after mixing it. To make the cleaning solution, follow the directions on the product label. For ordinary cleaning, 1 US gallon (3.8 L) of spray should be adequate. The spray wand should be narrowed to get the desired effect. However, the jet should not be so powerful that it bends the coil fins. 25 in (0.64 cm) spray is recommended. Pump sprayers greater than 2 US gal (7.6 L) are often a source of worry because of this. After that, let the coils to air dry for a few minutes.
    • Examine the condensate drain pan to ensure that you can see the filthy cleaning solution flowing down to the drain pan.
    • It may be necessary to direct the spray at the coils at a low angle in order to remove large clumps of trash.
    • 3 Brush the coils with a wet brush, washing the brush often. The brush should be washed thoroughly in a new bucket of clean water to ensure that no leftover chemicals or debris is introduced into the coils throughout the process. The brush removes large bits of dirt and debris that are too obstinate to be removed by the spraying method alone. Never brush your fingers across the fins, since this might cause them to fold or bend. As a result, the air flow will be obstructed. Short brush strokes guarantee that your brushing actions are exact and straight up and down the length of the brush.
    • After brushing the coils, spray both sides of the coils with the cleaning solution to eliminate any remaining loose debris.
    • A vacuum attachment with a brush attachment can be used to remove and collect all of the dust as an alternative.

    4 Reattach the evaporator coil access panel to the evaporator coil and tape it shut with HVAC tape.The metal foil tape should be applied to the panel’s top and bottom seams, as well as the corners.Make sure not to tape over the manufacturer’s label on the access panel, since service professionals may want this information in the future.HVAC is an abbreviation that stands for heating, ventilating, and air conditioning.

    1 Fill a spray bottle halfway with warm water and dishwashing detergent. Only a few drops of detergent should be used, and the detergent should not be excessively acidic. Acidic cleansers have the potential to induce corrosion to the copper and other metals utilized in the coil, resulting in a reduction in coil life. You may either use a hand sprayer or a garden sprayer to get the job done.

    1. Fill a spray bottle half-full of warm water and dishwashing detergent. Only a few drops of detergent should be used, and the detergent should not be too acidic. Cleaners containing acids can promote corrosion to the copper and other metals used in the coil, resulting in a shorter coil lifespan. Use a hand sprayer or a garden sprayer if you want.
    1. 1Buy a commercial cleaner to use on the evaporator coils to keep them clean. Most home improvement stores carry a number of different kinds of drywall adhesive. The majority of cleaners are of the foaming variety, which are designed to break down dirt and then drain away into the unit’s drainage system. 2Spray the cleaner directly on the coils to get the most effective results. Coat the surfaces with an uniform and deep layer of paint. It’s ideal to do this on a hot day because the air conditioning will have been running for a while before you arrive. 3 This will aid in the cleaning of the coils using condensate water. To clean the drain pan, pour 1 US quart (0.95 L) of a bleach/water solution into the pan. The bleach and water solution should be made up of half household bleach and half water, according to the manufacturer. This guarantees that the drain pipe is clear of algae and that it does not become blocked. Then, when the foam has rinsed itself off and drained away, it will correctly accumulate in your unit as a result of the drainage. If you want, you may purchase time-release algae pills to sprinkle in the drain pan.
    1. 1Get a professional cleaner for cleaning evaporator coils and put it in your garage or basement. Most home improvement stores carry a number of different types of paint. It is recommended to spray the cleaner directly on the coils because the bulk of them are foaming cleansers designed to break down dirt and then drain away into the unit’s drainage system. Surfaces should be coated uniformly and completely. When it’s hot outside, it’s ideal to do this since the air conditioning will already be operating. Because of this, condensate water may be used to rinse the coils more effectively. Fill the drain pan with 1 US quart (0.95 L) of a bleach/water solution. The bleach and water solution should be made up of half household bleach and half water, according per the instructions. The drain pipe will be clear of algae and unclogged as a result of this. Then, when the foam has rinsed itself off and drained away, it will correctly accumulate in your unit as a result of gravity. Another option is to purchase time-release algae pills to place into the drain pan.

    Why are evaporator coils important?

    The evaporator coils are responsible for capturing heat from the air within your home.The condenser coils release the heat that has been absorbed into the surrounding environment through the outside cabinet.Located within the interior air handling unit, the evaporator coils cool the air.They play a critical role in the overall performance of your air conditioning system.

    The cooling required to generate cold air to keep your business or house pleasant – even when temperatures soar – is provided by these units.The majority of the time, evaporator coils are composed of copper and wrapped by aluminum fins to aid in heat transfer.The evaporator coils also aid in the dehumidification of the space.In order for the coils to cool down, water condenses on them from the air circulating within your home.

    What happens if evaporator coils become dirty?

    • Pollen, dust, and other particles are commonly found in the air that is forced through the evaporator coils. Because the coils are often wet as a result of the dehumidification process, contaminants are easily attracted to them and adhere to them. When enough material accumulates on the coils over time, it might have an adverse effect on their overall performance. Ice formation on the coils
    • reduced heat transfer and cooling capacity
    • increased system wear, resulting in damage to the system
    • increased operating temperatures and pressures
    • increased energy consumption
    • and other issues might result if the evaporator and condenser coils get filthy.

    Pollen, dust, and other particles are commonly found in the air that blows across the evaporator coils.It is easy for contaminants to adhere to dehumidification coils since the coils are often wet from the process of dehumidification.Material can collect on the coils over time to the point that it has an adverse effect on their overall function.Ice formation on the coils; reduced heat transfer and cooling capacity; increased system wear, resulting in damage to the system; increased operating temperatures and pressures; increased energy consumption; and other issues might arise if the evaporator and condenser coils get filthy.

    How to clean your evaporator coils

    1)  Get needed supplies

    • Make a list of the things you’ll need. Wire, household bleach, a large hand mirror, a stiff brush, and a screwdriver are examples of such items.

    In addition, you must locate the evaporator coils. It’s possible that you have an air conditioner with a sealed plenum. If this is the case, you will be unable to clean the coils on your own. Make an appointment with a qualified HVAC professional.

    2)  Gain access to coil

    • You can begin cleaning your system as soon as it is not completely sealed. Remove the access panel from your interior air handling unit if it is not already done. The evaporator coils should be visible from the outside. Please consult your handbook if you do not know where these items are located. Once you have gained access to the coils, proceed as follows: Remove the screws from your unit and turn it off at the thermostat.
    • Place the screws and panels in a safe place where they will not be separated or misplaced.

    3)  Clean with a stiff brush

    It is possible to move the evaporator slightly out of the way once you have visibility of it.Once you’ve done that, clean the underside of your device with the stiff brush.With the hand mirror, keep an eye on the brush while you clean.Keeping the tray beneath the evaporator clean is also recommended.

    The tray is responsible for transporting condensation away.Fill the weep hole with a tablespoon of bleach or some comparable disinfectant to keep fungus from growing there.An obstruction in the drain pipe might be the cause of a lot of moisture in the house.If this occurs, use the wire to open the door as a last resort.

    4)  Use compressed air for cleaning

    • Compressed air is another another cleaning approach to consider. It is both effective and straightforward. Take the following steps: Direct the airflow over the coil in the opposite direction of the regular airflow
    • When dealing with rougher soil, move the nozzle closer to the dirt.
    • Continue to maintain a steady flow of air over the coil
    • Make sure that you are not blowing debris into the ductwork.

    Call the pros for more help

    Air compression is another cleaning procedure. Because it’s both efficient and straightforward. Steps to take include: Air should be directed over the coil (in the opposite direction of the regular airflow); and
    When dealing with harder soil, bring the nozzle closer.
    Continue to maintain a constant flow of air across the coil;
    Maintain a safe distance between you and the ductwork.

    How to Clean AC Evaporator Coils

    Avoid overlooking system components that are hidden within the system cabinet or within the air handler enclosure when it comes time for your air conditioner’s yearly preventive maintenance appointment.The evaporator coils in the unit are one of the more crucial of the device’s concealed components.Your air conditioner’s efficiency might diminish, its performance can suffer, and damage or failures can occur if the evaporator coils become clogged with debris.Here is some basic information on the operation of an air conditioner and the significance of evaporator coils, as well as some instructions on how to clean an air conditioner’s evaporator coils (if necessary).

    • Evaporator coils are responsible for capturing heat from the air within your house, while condenser coils are responsible for releasing that heat into the air around the air conditioner’s exterior unit. These coils are often composed of copper and are encircled by a series of aluminum fins, which aid in heat transmission by transferring more heat. The evaporator coils are located within the interior air handling unit, whilst the condenser coils are located within the outside cabinet of the HVAC system. The evaporator coils in your air conditioning system are critical to the overall cooling function of the system. In order to create the cold air that keeps your house or company pleasant even when temperatures are at their highest, they must supply the cooling that is necessary. It is also the evaporator coils that are responsible for the dehumidification that your air conditioner supplies. As the coils cool down, water condenses on them and is drawn out of the air in your home through the condensation process. This water is collected in a drain pan, where it is allowed to run away without being harmed. When evaporator coils get clogged, their ability to execute these two jobs is severely diminished. Depending on the coils, the air moving through them may carry dust, pollen, and other particles. Because the coils are frequently moist from the dehumidification process, pollutants have a very easy time adhering to them and being trapped. It is possible that dirty air filters in the system, or the absence of any filters at all, will increase the quantity of material that comes into contact with the evaporator coil. In a very short period of time, enough material can collect on the coils to have an adverse effect on the functioning of the machine. There can be a variety of issues that arise when evaporator and condenser coils become dirty, including: reduced heat transfer
    • decreased cooling capacity
    • increased energy consumption
    • increased operating pressures and temperatures
    • increased wear on the system, which can result in component damage, system malfunctions, and a shorter lifespan.
    • The accumulation of ice on the coil

    As a general rule, you should anticipate an air conditioner with filthy coils to consume about 40% more energy than an air conditioner with clean coils. It is possible to diminish the cooling function by as much as 30% or more. Even as your air conditioner’s efficiency and performance continue to deteriorate, your monthly power expenses will rise dramatically.

    Basic Air Conditioner Function

    Split-system cooling systems, such as central air conditioners, are comprised of two separate units: an inside unit and an outside one.A split system air conditioner has two parts: an outside unit that includes the condenser and condenser coils, and an inside unit that contains the evaporator and evaporator coils, as well as an air handling system.Heating and cooling systems use evaporator and condenser coils to absorb and disperse heat, respectively.According on where it is in the cycle, refrigerant transitions from a liquid to a gas and back again as it cycles.

    During these changes of state, heat is absorbed or released, and cooling is created for your residence or place of business as a result of the process.The heat contained in the gaseous refrigerant is compressed in the compressor of the external unit, which is located outside the home.It then passes through a condenser, where it is heated and finally released into the surrounding air by a compressor coil, which is located outside the unit.It is during this procedure that the refrigerant is restored to its liquid condition.Once in the evaporator, the liquid refrigerant is converted to a gas by the process of condensation.At the same time as this activity is taking place, the refrigerant absorbs heat from the surrounding air.

    1. After becoming extremely cold, the evaporator coil serves as the source of the cool air that is circulated throughout your home.
    2. After passing through the cold evaporator coil, the air handler directs the cool air into the ducting system.
    3. It is then distributed throughout your house via vents and registers located at the extremities of the duct network.
    4. It is through return ducts that heated spent air is returned to the system, where it is filtered and the cycle begins all over again.

    The Importance of Regular AC Maintenance

    Preventive maintenance is crucial to ensuring that your air conditioner continues to operate at peak performance.Maintenance should be conducted at least once a year, ideally just before the cooling season begins to kick in.Seasonal maintenance should be performed by a qualified HVAC technician in the majority of circumstances.System testing and adjustment, minor repairs and component replacements, air filter changes, and cleaning of the evaporator and condenser coils are all tasks that are completed by the technician.

    Some of these maintenance jobs, such as replacing the air filter, may be completed by the homeowner on their own.If you are mechanically inclined, you may also clean the evaporator coils on your air conditioning system.Depending on the type and quantity of cleaning required, the following are some helpful procedures for cleaning air conditioning evaporator coils.Additionally, same procedures can be utilized to clean the compressor coils located in the exterior cabinet.

Because auto owners can simply clean evaporator coils without removing the complete system, there is no need for them to take their vehicles to a detailer for service. Learn how to do so by reading on:

    Step 1: Remove the Glove Box

    Given that you will not be removing the full system during this procedure, you will simply need to remove the glove box.It is possible to distinguish between different automobile models by the way their glove compartments are constructed.Some glove boxes may be readily removed by simply opening them up, pressing their edges together, and dragging them out of their slots.Others might need additional procedures such as unplugging a cable from the side that supports the glovebox, unplugging an arm support from the side, unfastening a few screws, and so on.

    Step 2: Access the Evaporator Coil

    The evaporator coil is located near the firewall that separates the engine compartment from the passenger compartment.In order to clean the evaporator coil in your automobile, you would need to create a means of getting to the evaporator coil.Access to the evaporator coil can be gained by one of three methods.The most straightforward method of gaining access to the evaporator coil is to remove the blower fan from the unit.This may be accomplished by detaching the terminal that is connected to the blower motor by pressing the plug inward and drawing it out from the blower motor terminal.

    • Then you’d take out the three screws that hold the blower motor to the underside of the dashboard and take it all apart.
    • Another approach that you may use to gain rapid access to the evaporator coil is to remove the resistor block from the evaporator.
    • One word of caution: if the resistor block was operating only moments before you began this job, let it to cool for at least five minutes before removing it.
    • First and foremost, detach the negative battery cable and store it in a location where it will not come into touch with any metal surfaces.
    • Then remove the two screws that secure the resistor block to the housing and store them somewhere safe so that they don’t get lost.
    • However, if you are still unable to gain access to the evaporator coil after removing either of the aforementioned components, you can drill a hole measuring 3/8 of an inch between the blower fan and the evaporator casing to gain access to the coil.
    1. Just be sure you use extreme caution so as not to damage any other components.
    2. This third method is a high-risk activity that necessitates extreme prudence, therefore it should only be used as a last resort when absolutely required.

    The evaporator coil may be located near the firewall that separates the engine compartment from the passenger compartment of the vehicle.Making a way to reach the evaporator coil in your car is necessary in order to clean the evaporator coil in your automobile.Accessing the evaporator coil can be accomplished in one of three ways: Removal of the blower fan would be the most straightforward method of gaining access to the evaporator coil.This may be accomplished by pressing the plug inward and drawing it out, which will disconnect the terminal that is connected to the blower motor.Afterwards, you’d remove the three screws that hold the blower motor to the bottom of the dashboard.

    • Alternately, disconnecting the resistor block from the evaporator coil might provide you with more immediate access to the coil.
    • Simply said, if the resistor block was operating only moments before you began this job, allow it to cool for at least five minutes before removing it from its position.
    • The first step in removing the resistor block is to detach the negative battery connection, which should be stored somewhere where it will not come into touch with metal.
    • Then remove the two screws that secure the resistor block to the housing and store them somewhere safe so that they don’t go misplaced again.
    • However, if you are still unable to access the evaporator coil after removing either of the aforementioned components, you can drill a hole measuring 3/8 of an inch between the blower fan and the evaporator casing.
    • However, you must proceed with extreme caution so as not to damage any other components.
    1. When it comes to the third alternative, it is a high-risk endeavor that demands extreme prudence, and it should only be used as a last choice in extreme circumstances.

    Step 4: Rinse the Evaporator Coil

    It would next be necessary to rinse the evaporator coil once the cleaner had completed its task with its foaming effect.If you want to clean the evaporator coil, you can do it in two methods.One method is to use a garden hose and merely give it a gentle spray, as seen below.However, you must take care not to allow the water to overflow into the interior of your vehicle.You may want to enlist the assistance of another person to check on the water.

    • The alternative method is to use a spray bottle and spray clean water on it until it is clean.
    • If you are uncomfortable with the use of a hose, you can use this approach instead of the one described above.

    Step 5: Dry the Evaporator Coil

    To dry the evaporator coil, you can use a towel to absorb the moisture. Alternatively, a blow dryer or hairdryer can be used.

    Step 6: Put Back the Blower Fan or Resistor Block or Seal the Hole You Drilled

    After you’ve finished cleaning and drying the evaporator coil, it’s time to replace the blower fan or resistor block that you removed in order to get access to the evaporator coil earlier.Simply rejoin the plug you previously removed from it and screw it back into place.Another option is to plug the hole between the blower fan and evaporator case using RTV silicone, if one has been drilled between the fan and the evaporator case.

    Step 7: Put Back the Glove Box

    After the evaporator coil has been thoroughly cleaned and any removed parts from the bottom of the dashboard have been restored or the hole bored has been shut, you may proceed to the last stage. And the final step is to reinstall the glove box, which may be accomplished by just reversing the process of removing it.
