Frequently Asked Heat Pump Questions

What is the benefit of using a heat pump?

A heat pump provides very energy efficient heating and cooling for your home, especially in our moderate Seattle climate. When properly installed, an air-source heat pump can deliver up to 3 times more heat to a home than the electricity it consumes. (If you translated that to a gas furnace, that would be an AFUE of 300%). How can this be? A heat pump moves heat rather than converting it from a fuel like a gas furnace does. It uses a small amount of electricity to run. So it’s very energy efficient.

York’s heat pumps are rated “most efficient” by EnergyStar. 

How does a heat pump make heat?

Heat pumps transfer heat from one area (a source) to a  different area. They are able either to cool or to heat, based  on the positioning of a reversing valve. Generally, they transfer heat from the air, which is why they are also called air source heat pumps. Unlike fossil fuels, air is free, which is why it is so energy efficient. While you might think it’s cool outside, your heat pump can find the residual heat in the air down to about freezing, and bring it into your home. Once it gets too cold outside, you will need a backup heat source such as an electric or gas furnace.

Heat pumps work by expanding and compressing refrigerant, which creates an exchange of energy.  The heat pump has an outdoor coil, refrigerant, a compressor and an indoor coil.

How does a heat pump cool the house?

The heat pump essentially reverses it’s heating process. Similar to a refrigerator, the heat pump refrigerant absorbs heat and creates condensation outside of the coil. A fan  pushes that super cool air into the ducts.

Are there utility rebates or tax credits available for heat pumps?

Yes, there are heat pump utility rebates up to $2500, and tax credits available on select models. Learn more here: Utility Rebates and Tax Credits Available*

What does HSPF and SEER mean in relation to heat pumps?

How efficient is your air source heat pump? Heat Pump efficiency is show by a measure called the heating season performance factor (HSPF). This is a calculation made from: the total space heating required during the heating season, expressed in Btus (British Thermal Units), divided by the total electrical energy consumed by the heat pump system during the same season, expressed in watt-hours. It’s basically the ratio of heat out to electricity in. The HSPF includes the efficiency of all of the elements in the heat pump and the top efficient models, rated Most Efficient by EnergyStar will have an HSPF of 8-10.

Since heat pumps also provide cooling you will want to also know about the cooling energy efficiency of the unit. The SEER or seasonal energy efficiency ratio is also a rating used for heat pumps. It is total BTUs of heat removed from the conditioned space during the annual cooling season, divided by the total electrical energy consumed by the heat pump during the same season, expressed in watt-hours. So, how much cooling it does relative to the electricity needed to run it.
