Evaporator Coils

If you’re familiar with indoor comfort control, then you know that staying cool in the summer and warm in the winter is all about moving heat energy. In the summer you want heat energy moved out of your home, and that’s where an evaporator coil comes into play.

You see, without an evaporator coil, your air conditioner wouldn’t be able to do a thing. An air conditioner doesn’t blow cold air into a home. It compresses a gas called refrigerant. That’s why you’ll sometimes hear an HVAC contractor call an air conditioner a “compressor” or “condenser.”

When refrigerant is compressed, heat energy is dissipated into the air outside, and the refrigerant condenses down to a chilled fluid. The refrigerant is then pumped inside to the evaporator coil. The fan motor in the furnace pulls air from the home, and forces the air through the evaporator coil. The refrigerant absorbs heat energy which cools the air, and the process repeats.

As with any mix of cold and hot air, water condenses in the coil. This creates a damp, dark interior that is a prime spot for mold to grow. Installing a UV lamp in your coil will kill air and surface mold before it pollutes your air and robs your efficiency.
