What we did
In April we were called to a home in Versailles where the evaporator coil had a buildup of dirt and grime. The evaporator coil sits indoors and is the part of the system that pulls heat and moisture out of the air, so what collects on it has a direct effect on how well the system can do its job.
We gave the coil a thorough cleaning, including a chemical bath. Once the work was done, all components were functioning smoothly. Taking care of this in the spring gives the system a clean start before the cooling season gets going.
A dirty coil can make it harder for an air conditioner to move heat, and that loss of efficiency tends to show up when the system is working hardest. In Kentucky, where summers bring long stretches of heat and humidity, a clean coil helps the system keep pace with the weather. It is a part of the system most homeowners never see, which is exactly why it is worth having a technician check it as part of regular care. If your system seems to be working harder than it used to, the coil is one of the places we look.
