FAQ/Myth
Answer/Response
With furnaces (natural gas, electric resistance, or propane), it’s recommended to set your thermostat back three-six degrees at night or when the house will be unoccupied for more than 4 hours. With heat pumps, in the winter it’s not recommended to set your thermostat back at all, unless you plan on being away for 10 hours or more. In those scenarios, it’s recommended to set your thermostat back only three-four degrees. Air source heat pumps do not generally provide both space heating and domestic hot water production. However, many air-to-water heat pumps have the ability to provide domestic hot water through an isolated heat exchanger. Air source heat pumps are used in heat pump water heaters. Heat pump water heaters use the same concept but only heat domestic hot water. These are widely available and eligible for Focus on Energy discounts.

Should I use my ceiling fans with my air source heat pump?
Ceiling fans provide air movement which may enhance comfort. Use of the ceiling fan is based on personal comfort and preferences.
The installed cost of a heat pump will depend on many factors such as whether there’s need for ductwork modifications, electrical upgrades, and complexity of the installation. That said, a major driver of heat pump cost is the compressor, or the “engine” of the heat pump. Note that all mini-split heat pumps have variable-speed compressors. Ultimately, you will need to discuss various options with your contractor that may present higher or lower installed costs and varying levels of performance. See section on Buying a Heat Pump for more information.
