With YORK® heat pumps, the air outside the home is used as the heat source during the heating cycle. Load Calculation Performed by an HVAC professional, this calculation helps determine what size system is needed for a home (how much heating or cooling) based on how much heat is gained or lost.
What causes poor indoor air quality? Common air pollutants include: CO generated by some machines as they operate both indoors and outdoors (motor vehicles, electric generators, gas powered tools) Pollen Smog (a combination of smoke and fog) VOCs are chemicals that contain carbon and can be introduce into the air as gases.

Basic Cooling Cycle. The basic cooling cycle is the same for both vaporcompression and absorption chillers. Both systems utilize a liquid refrigerant that changes phase to a gas within an evaporator which absorbs heat from the water to be cooled. The refrigerant gas is then compressed to a higher pressure by a compressor or a generator, converted back into a liquid by rejecting heat through a
