Air Quality | Self-Correct AC Problems
Air Quality | Not having to call in the experts for all your AC issues can be liberating and cost-efficient. Check out some of these common ac problems and how you can fix them yourself!
Clogged Drain Line
Air conditioners pull moisture out of humid air while lowering the temperature. The moisture is typically drained out of your home through your plumbing system. A drain pan should be present as a back up with a secondary condensate drain. Algae can grow in these lines, clogging them up. This can lead to water damage in your home. We clear the drain lines as part of our Spring A/C tune-up, or you can have it done separately as needed.
A contactor is an electromechanical switch in your air conditioner. Sometimes the coating on a contactor will wear off and it will stick, causing the outside unit to run continuously, which is expensive! At times ants are attracted to the electricity and get caught between contactors blocking them from closing. If this happens, the outside unit won’t run. Contactors can also fail electrically. We check these as part of a Spring tune-up, clean the surface of the contactors if needed, and recommend replacement if failure appears imminent.
Dirty Evaporator Coil
The evaporator coil is located inside a home. Liquid refrigerant is pumped into this coil to evaporate and draw heat from the air being blown across the coil. Periodically it needs to be cleaned or dust and build up will restrict heat transfer capabilities and reduce air flow down the ducts. Dirty coils can increase operating costs while reducing comfort.
Dirty Condenser Coil
The condenser coil is located outside of a home. The compressor pulls refrigerant gas from the evaporator and pumps it through the outdoor coil where it condenses into a liquid as the condensing unit fan pulls air across the coil. A dirty or restricted coil is inefficient, increasing electricity usage and reducing cooling capacity.
Your heating and air conditioning system adds and removes heat to the duct system. The duct system is tasked with delivering it to the occupied areas of your home. If the ducts that supply air to the living space leak and are located outside of the living space, you’re essentially paying to cool the outdoors! If the ducts that return air leak, you pull in unconditioned, unfiltered air. Duct leakage is one of the leading causes of inefficient A/C operation. Leaks can range from duct penetration to split seams to completely disconnected ducts. It’s the leaks that cost you the most money on your energy bill!
