Green City has been providing the absolute best in heat pump service, repair, and installation for the Seattle area. Whatever your heat pump needs, the experts at Green City Heating and Air Conditioning are prepared and ready to meet them.

A heat pump is an air conditioner that can reverse its process by absorbing heat from outside and then transferring that heat through the refrigerant lines to the indoor coil installed with your furnace. The heat is then released into your duct system by air flowing over the heated coil. This process can work even when it’s below freezing outside with the proper equipment and installation.

Heat pump installation and maintenance is something that should only be entrusted to the experts. With a distinguished track record of excellent work and customer satisfaction, Green City is the obvious choice
