Dirty A-Coil in Your Furance is a Contamination Risk

October 2nd, 2011 3:36 PM by Dan Howard

This is a dirty "A Coil" This is the part inside of your furnace that becomes cold when the air conditioner is operating. The blower pushes air over the cold A-Coil and the house chills. This area also collects condensation just like a glass of ice water would sitting out on the 4th of July. That water collects on and in the tray under the coil.

However, when a coil is this dirty, mold also grows on the dirt and moisture on the coil.  As apart of regular furnace maintenance, this cleaning is usually ignored. Even more surprising, we often find that the A-Coil and furnace blower are not cleaned when the ductwork is cleaned. This blows the mold and dirt into the ductwork and air in the home as soon as the unit turns on. So much wasted money and effort for cleaning the ductwork....if these other areas are not also cleaned
