Cleaning Air Conditioning Coils

470239098The Air & Heating Guru recommends cleaning air conditioning coils on a regular basis to ensure your AC operates flawlessly with high efficiency. Since these devices are involved in filtration, movement and cooling of air, they are often exposed to a lot of dust, pollen and smoke among other types of airborne particles. These impurities can form an insulation around the coils of the air conditioner.

Why It’s Important to Clean AC Coils

There are two types of AC coils, condenser and evaporator coils. The latter is located in the air handling unit and usually gets into direct contact with air circulating in a room. On the other hand, condenser coils are located outdoors, or in a separate room, so they never come into direct contact with air circulating in a room. These coils are tasked with heat exchange. They work by radiating heat into the surrounding air (condenser coils) or absorbing heat from the surroundings (evaporator coils). When dust and other types of debris settle around these coils, they form an insulation, which reduces the ability of these coils to absorb or release heat into the environment. This forces your AC to work harder, consume more energy and break down more frequently. Therefore, it is in your best interest to clean them on a regular basis.

Cleaning Air Conditioning Coils

We recommend you unplug the AC from the power outlet, or breaker, before you start working. This is an important safety precaution. If you have a split air conditioner, trim or uproot plants growing around or over the condenser unit. Remove the outer casing or access panel while keeping any type of fastener, such as screws and bolts, in a safe place. Use a soft piece of cloth to wipe the coils, fan blades and all surfaces in the condenser and air handling unit. Remove any dust by vacuuming. Consider using non-foaming detergent that is biodegradable to loosen grime and tough dirt from the unit. After cleaning, remember to lubricate moving parts and apply mold inhibitor.

If you do not have the time or technical capacity to clean your AC coils, we recommend you hire a reputable HVAC company. Follow us for everything you need to keep your home running efficiently.
