We install heat pumps in Chandler, AZ!
The exact type of refrigerant and the amount uses varies by model, as do the precise details of the heating and cooling process. The general parameters are unchanged, however. The refrigerant starts out as a gas before entering a compression valve that subjects it to a huge amount of heat and pressure. It then releases the gas into a series of compression coils, where the heat is bled off and the gas reverts to a liquid (still under a lot of pressure). From there, it moves through an expansion valve, which releases a set amount into a series of evaporator coils. As it evaporates, it cools the surrounding air: reverting to a gas and return back to the compression valve to start the cycle again.
As you may have noticed, there are two sets of valves/coils: one that heats the surrounding air and one that cools it. In a heat pump, there’s one set of valves/coils inside the house and one set outside. In the summer, the inside set serves as the expansion/evaporator, cooling the air, while the outside set serves as the compressor, warming the air. In the winter time, the two roles are basically swapped, and the inside set warms the air while the outside set cools the air.
The process is very cost efficient – saving you money over a traditional gas furnace – and it works well in areas with mild winters, which is why heat pumps in Chandler, AZ are fairly common.
