Otherwise, the homeowner may inadvertently damage the coils, causing further problems. With knowledge and caution, you can keep your AC unit in premium condition by cleaning the coils correctly and regularly. After spraying your condenser coils with water, you'll want to use a commercial or homemade cleaner to continue the job. After applying a foam or a detergent mixture, the garden hose comes into play again for rinsing away the residue from the cleaners. After the final rinse, allow all parts of the outdoor HVAC unit to air dry for at least 60 minutes before reattaching the covering panels and restarting the system.
A Specialized Cleaner Will Enhance the Cleaning Process
This heat transfer process is accomplished via a compressor that heats and pressurizes the refrigerant flowing through a conduit from the indoor to the outdoor unit. As the refrigerant flows through the condenser coils, the heat is released via an exhaust fan blowing through the coils to disperse the heat outdoors. You should clean both the evaporator and condenser coils in your HVAC system at least once a year.
Cost-effectiveness
Use a wet/dry vacuum with a soft brush attachment to remove any remaining residue. This ensures a thorough cleaning without damaging the coils. Prevent an expensive refrigerator gasket repair bill and cut down air leaks by keeping your door gasket clean. Syrup, jelly or any other sticky stuff dripping down the front sides of your refrigerator can dry and glue the gasket to the frame.

Preparing the Air Handling Unit
The refrigerant moves to the outside unit, where it goes through the compressor coil to cool down. Over time, this added strain on the system may contribute to premature wear and tear of components. Operating your air conditioner with dirty evaporator coils can potentially lead to more frequent breakdowns and the need for costly AC repairs. Cleaning your evaporator coil helps your air conditioner or heat pump system work efficiently and can also prolong its life. It’s normally attached to your furnace, and we recommend having it cleaned each year before heating season begins, but it’s ideal to repeat mid-season.
Lennox AC Costs: What Affects the Price?
Should this gets out of hand, it could spread through your air conditioning system. There are several cleaning agents specially designed to wipe away the common types of build-up around evaporator coils. These often also come with specialized sprayers to apply the cleaning agent. When the evaporator coil struggles to absorb heat, the whole system is affected. Your air conditioning system will not be producing as much cool air as it would if everything were working properly.
A clean evaporator coil will have an easier time absorbing heat and doing its part in the air conditioning system. When your AC system works efficiently, it will help you stay cooler, and it won’t drive up energy costs. If the coils are located on the bottom of the fridge like ours, clean the condenser fan and the area around it. At times, paper, dirt, dust and even mice can get sucked into the fan and bring it to a complete stop. Clean the coils with a special refrigerator coil cleaning brush to loosen the dirt and dust.
Step 1: Gather Your Tools
To clean an evaporator coil, you can use a soft cloth with a specialized cleaning agent or a mild detergent. You may use a soft bristle brush only, but you must take heed not to damage any of the coils or other components. Begin with opening the access panel to get a good view of the next steps. You may want to begin with a vacuum cleaner hose to suck up all the loose dirt and debris.
How To: Clean a Fan
It also enhances indoor comfort and saves on operating and repair costs. If you don’t want to invest in a piece of specialized equipment like the fin brush (which can be purchased for $15 or more online), go ahead and skip this step. Correcting bent fins goes above and beyond the task at hand—cleaning the coils—from which your machine will already receive an efficiency boost. Visually inspect the coils for any large debris like leaves, spider webs, or clods of dirt. Remove these by hand, then dust off the coils using a coil brush.

However, some heat pumps have an electric heat strip added to the indoor fan coil for improved heating capabilities. A licensed HVAC professional will clean your AC coils while performing routine maintenance on your air conditioner. A professional should service your air conditioner twice a year, although once a year is sufficient for certain HVAC systems. While a technician is cleaning your coils, they’ll also perform any coil troubleshooting necessary to determine if your AC coils are causing bigger problems for your unit.
Most A/C units are located outdoors and should have sufficient ventilation for working with coil cleaner. If you do not expect adequate ventilation, use a NIOSH mechanical filter/organic vapor cartridge in a respirator. If the cleanser label says to do so, rinse off the foaming cleaner using your hose. You will need good water pressure and slow, back-and-forth motions to thoroughly rinse the cleanser off. Indoor units cleaned using rinse-free cleaner simply need to start up; the condensate will rinse off the cleaner on its own. If there is a lot of build-up on or around your evaporator coil, this could be a prime opportunity for bacteria and mold to grow.
You can make your own cleaning solution following these suggestions. Action Air recommends diluting white vinegar with water in a spray bottle and spraying the mixture onto dirty AC coils. White vinegar is an effective natural cleaner due to its acidity level. For greasy or sticky residue on the coils, you may want to add 1 tablespoon of baking soda to the diluted vinegar solution. Alternatively, you can achieve good results by mixing a mild dish detergent with water in a spray bottle and spritzing the coils. If your coils are still dirty, and there’s lots of dirt built up between the fins, you might need to utilize the power of compressed air.
Disconnect the power to the air conditioning unit and turn the power off at the breaker. Start by using the nylon scrub brush to remove any big chunks of dirt or debris from the coils. Before you do anything, make sure the power is off to the AC unit (switch the electricity off at the breaker panel—don’t rely on the on/off button). For best results, start by spraying the AC unit from the inside out, starting at the top of the unit and working your way down. This will help prevent any soap residue from dripping onto clean coils.
Using the wet function on your shop vac, vacuum the unit’s interior again to remove any loosened dust, debris, and excess water. Using your purchased coil cleaner, follow the packaging instructions to apply it to the coils. Usually, you will simply spray the coils with the cleaner and leave for a few minutes. Let’s start with how to clean condenser coils — these ones are located outside. These coils run through aluminum fins also, but the refrigerant goes from liquid to gas instead.
