Do you know what the refrigerant in your HVAC system does?

Heating season is in full swing. Do you use a heat pump to heat your home? If so, chances are your system contains refrigerant.

There are many components that make your HVAC equipment work. One of these components is your refrigeration system. Refrigerant facilitates the transfer of heat either to or from air that is distributed throughout your home. Refrigerant removes heat from the air as it evaporates and adds heat to the air when it condenses. Evaporation and condensation occurs in coils of the same name – the indoor, evaporator coil and the outdoor, condenser coil. In different portions of the cooling cycle (or heating for heat pumps), your refrigerant is either a liquid of a gas.

A few years back, the HVAC industry had to switch from R-22 refrigerant (Freon) to R-410A. R-410A does not contain chlorofluorocarbons (a.k.a. CFCs). This means that it does not contribute to ozone depletion were it to escape into the air. Other refrigerants, like R-22, do contribute to ozone depletion.

If your heat pump isn’t heating or cooling correctly, there could be an issue with your refrigerant system. Make sure you always call a contractor for HVAC system maintenance. You don’t want to attempt to repair your refrigerant system unless you know what you’re doing. Not only is refrigerant expensive, you could damage one of the other crucial components of your system (like your compressor or coil) leaving you with a much bigger repair bill and a longer time without heating or cooling.
