As the Sterling HVAC professionals, our team at Donmar Heating & Cooling knows that maximizing efficiency is a top priority for all of our friends and neighbors in the area. For many homes, heat pumps are a great way to save money and help the environment without sacrificing comfort.

The refrigerant chemicals absorb heat at the indoor coil, becoming gaseous in the process.
