As the summer heat rages on, HVAC units in homes around the United States are getting used daily. If you want to keep the inside of your home at a comfortable temperature, then keeping your HVAC unit functional is imperative. Residential HVAC units need a few basic things to produce a steady flow of cool air.
The refrigerant in your HVAC unit is responsible for absorbing the heat in the air that your system pulls in from outdoors. As this air runs through the evaporator and compressor, the refrigerant helps to cool it down. Refrigerant leaks are quite common, especially in older units.
