Heating Los Angeles Heat pumps are a third option to warm your home. Particularly common as a heat source in California, heat pumps (also known as two-way air conditioners) pull hot air out of the home during warm months, and during the cold months pulls cold air from outside into the heat pump, warming the house. Heat pumps are proven to be more energy-efficient than both furnaces and boilers. Southern California residents should consider this less discussed option when looking for a new home. They operate with a simple mechanism: A fan pulls air in and over a heating element. The heat generated in the process is transferred to refrigerant in tubes in coils in the evaporator and turned into a high-pressure gas. This hot gas then flows through another set of coils where it loses pressure and cools, condensing into a liquid that absorbs heat from the outdoor air. In warmer months, this flow goes backward as cold air is absorbed from outside. 13654 Victory Blvd Unit 487, Van Nuys, CA 91401, United States 8184658143 Last Post 13654 Victory Blvd Unit 487, Van Nuys, CA 91401, United States 8184658143
