Heat Pump Repair

What Is a Heat Pump?

Heat Pumps are like air conditioners that run in reverse during the heating cycle. During the A/C cycle, the outside condensing unit is hot and the inside evaporator coil becomes cold. When running the Heat Pump in heat-mode a part called a reversing valve changes the flow of refrigerant so the inside coil is hot and the outside condensing unit is cold, absorbing the energy of the outside air. They are a good option in mild winter climates like we have in Northern California. 

​Pros of a Heat Pump

  • A great option for heating a home where natural gas or propane isn't available

  • No flammable gas to worry about

  • No Carbon monoxide threats because no open flame

If you are looking to have your heating and air conditioning equipment serviced, repaired, or replaced we can help. Sierra Aire is locally owned and operated servicing the greater Sacramento area. 

Cons of a Heat Pump

  • Can cost more in energy than a gas furnace

  • Heat Pumps efficiency is reduced as temperatures fall

  • When very cold there may not be enough energy in the outside air for a heat pump to heat the home effectively, requiring the use of additional electric heat strips
