Evaporator Coil

An evaporator coil is a series of copper piping contained inside a metal cabinet that sits on top of a furnace. The copper piping runs from the indoor coil to the air conditioner or heat pump outside.

When cooling in the summer, an air conditioner sends chilled refrigerant (R-410A) inside to the evaporator coil. The furnace fan pulls air from the home via the return air ducts, and forces this air through the frigid evaporator coil piping. The coil extracts heat from the air while moisture also condensates on the cold piping, removing extra humidity.

The cooled air is sent back into the duct system for distribution throughout the home and the R-410A refrigerant returns outside to the air conditioner which then pressurizes the refrigerant removing the heat before sending back inside.

Get More Comfortable Advice: Have your local AC contractor install a UV lamp (UV air purifier) inside your indoor coil. The UV lamp will prevent mold from growing in the dark, damp interior of your coil system. Mold growth can cause mold spores to be sent into your indoor air, and it will also lower the efficiency of your coil meaning.
