Heat Pumps are very popular especially in the South where air source heat pumps are mostly favored over straight air conditioners with a gas furnace for heating. With a heat pump one system can do it all especially in the mild winters of the South. In the North some people rely on a geothermal heat pump system or a water source heat pump where the heat is extracted from the ground instead of the air like an air source heat pump works. While air source heat pumps are cheaper to install the geothermal heat pump systems will save a lot of money over the life of the heat pump in operating costs so as far as efficiency is concerned the geothermal heat pump rules the day. There may be a time when your heat pump will begin giving you problems so we decided to post an article to help some people diagnose the heat pump problem in an effort to better understand the system.
