What Temperatures Do Heat Pumps Work In?

A heat pump is one of the most energy-efficient approaches to heat and cool your North America home. That’s since they shift warm or cold air, as opposed to making it. But not everyone has been able to enjoy this energy-saving technology.

At one time, heat pumps were only recommended for warmer climates, because they were less effective when temperatures were around or below freezing. When the heat pump couldn’t match demand, the heating system would then trigger pricier electric heat as a backup heat source to keep the house cozy.

With updated technology, heat pump systems are now ideal for chillier areas. Most can operate well at much chillier temperatures, although some might still need a secondary heating system if temperatures get too chilly. But it’s crucial to be aware that today’s auxiliary heating systems can also be more energy-efficient than previously.

We’ll go over the differing types of heat pumps so you can select the ideal one for your house.

Air Source Heat Pumps: Ideal for Moderate Areas

Air source heat pumps are the most installed type of heat pump. They use an outdoor unit and an indoor air handler. These systems transfer heat from either the indoor air during the warm weather, or outside air during the winter, keeping you comfortable year-round.

With updates in heat pump technology, these systems can now be installed in a wide range of climates. But keep in mind that you will likely need a backup source of heating if temperatures get colder than 10 degrees Fahrenheit. This could include a dual-fuel system with a gas furnace. Heating switches between the two to provide the most energy-efficient heating comfort across your residence.

As a result of the need for dual-fuel systems in colder climates, air source heat pumps are best suited for locales without big temperature changes and lower heating requirements.

Mini-Split Heat Pumps: Recommended for Areas Without Ductwork in Colder Climates

Mini-split heat pumps are one of the most adaptable types of heat pumps as they don’t have to have ductwork. This means you can use them just about in any room in your home, such as a garage or addition. They’re also highly energy efficient, with the majority achieving ENERGY STAR® designation.

Mini-splits have an outdoor unit that connects to as many as four quiet, small indoor units fixed on your wall or ceiling. This provides you with zoned heating and cooling, with precise temperature control in each room.

Outdoor air on even the most frigid days contains some heat that your ductless heat pump can use and send indoors. Depending on the model you select, some cold-weather mini-split heat pumps from Mitsubishi can work in temperatures as cold as -13°F.

Geothermal Heat Pumps: Recommended for Wide-Ranging Temperatures and Large Yards

Geothermal heat pumps take advantage of balanced underground temperatures to significantly lower your heating and cooling costs, typically by 25%–50%! These systems rely on underground pipes to move heat to and from your residence.

Geothermal is quiet and can run a long time—approximately 25 years for the indoor unit and around 50 years for the loop.

It doesn’t have to have a lot of upkeep and is ideal if you reside in an extreme climate. Most of the time, geothermal does not need a secondary heating system.

However, you’ll need a large amount of space and the correct kind of soil to add the underground loops. You should also know that installation is around $20,000–$25,000 for a 2,500-square foot house. Although the installation cost is more expensive, continuing energy savings might help the unit pay for itself over time.

Because geothermal saves a lot of energy, installing it could qualify you for federal tax credits and other rebates from your area energy provider.
