What Temps Do Heat Pumps Work In?

A heat pump is one of the most energy-efficient methods to heat and cool your the U.S. home. That’s since they move warm or cold air, rather than creating it. But not everyone has been able to take advantage of this energy-saving technology. 

In the past, heat pumps were only recommended for moderate areas, because they were less effective when temperatures were near or below freezing. When the heat pump couldn’t provide the desired temperature, the heating system would then trigger pricier electric heat as an emergency heat source to keep the residence comfy. 

With new technology, heat pump systems are now ideal for chillier locations. Most can work smoothly at much lower temperatures, although some might still need an auxiliary heating system if temperatures get too chilly. But it’s important to be aware that today’s emergency heating systems can also be more energy-efficient than in years past. 

We’ll discuss the differing styles of heat pumps so you can find the best one for your house. 

Air Source Heat Pumps: Right for Moderate Locations 

Air source heat pumps are the most used style of heat pump. They use an outdoor unit and an indoor air handler. These systems transfer heat from either the indoor air during the summer, or outside air during the winter, keeping you cozy year-round. 

With updates in heat pump technology, these systems can now be used in a large range of climates. But keep in mind that you will typically need an emergency source of heat if temperatures go below 10 degrees Fahrenheit. This may entail a dual-fuel system with a gas furnace. Heating changes between the two to give the most energy-efficient heating comfort across your home. 

As a result of the demand for dual-fuel systems in chillier climates, air source heat pumps are recommended locales without large temperature changes and lower heating requirements. 

Mini-Split Heat Pumps: Ideal for Areas Without Ductwork in Cold Climates 

Mini-split heat pumps are one of the most versatile types of heat pumps since they don’t need ductwork. This means you can add them just about in any room in your home, including a garage or addition. They’re also very energy efficient, with the majority receiving ENERGY STAR® designation. 

Mini-splits have an outdoor unit that joins to as many as four quiet, low-profile indoor units fixed on your wall or ceiling. This gives you the ability to have zoned heating and cooling, with exact temperature control in each room. 

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

Geothermal Heat Pumps: Recommended for Harsh Temperatures and Big Yards 

Geothermal heat pumps take advantage of balanced subsurface temperatures to tremendously reduce your heating and cooling bills, usually by 25%–50%! These systems rely on buried pipes to shift heat to and from your house. 

Geothermal isn’t disruptive and can run for many years—around 25 years for the indoor unit and around 50 years for the loop. 

It doesn’t require a lot of upkeep and is best if you reside in a climate where temperatures vary greatly. Most of the time, geothermal does not require an auxiliary heating system. 

However, you’ll need a good amount of space and the ideal kind of soil to install the underground loops. You should also be aware that installation can run around $20,000–$25,000 for a 2,500-square foot home. Although the installation cost is high, ongoing energy savings may help the geothermal pay for itself over time. 

Since geothermal conserves a lot of energy, using it may make you eligible for federal tax credits and other rebates from your area energy provider.
