Did you know that there are two parts to your central air conditioning system? There’s the outside unit, which is what most people think about when they think of an air conditioner. But there’s also an inside unit called an evaporator coil — more commonly called an A-coil because of its shape. This unit is hard to see, as it’s inside the ducting connected to your furnace.
The dust microparticles that accumulate on your A-coil can greatly diminish cooling efficiency. A-coils should be cleaned periodically to ensure your air conditioner is efficiently blowing cold air. Through study and experience, we now know that A-coil cleaning is recommended every five years for good air quality, and it’s not part of your air conditioner’s annual precision tune-up. An air conditioning system with a contaminated evaporator coil will need to run longer to cool your home, wasting your money on needlessly expensive energy bills.
A-coils produce condensation, which, when mixed with caked-on dust and microparticles that cannot be picked up by a regular filtration system, become a haven for mold and mildew. This can affect allergies, aggravate respiratory problems and, in extreme cases, lead to Legionnaires’ disease.
Outdoors, Legionella bacteria survive in soil and water, but rarely cause infections. Indoors, however, this bacteria can multiply in all kinds of water systems: Hot tubs, air conditioners, even grocery store misters. Dirty A-coils are a major cause of poor indoor air quality and will shorten the life of your equipment. At Anchor ClimateCare, we are committed to you, your air, your equipment, and your energy savings.
