What Temps Do Heat Pumps Work In?

A heat pump is one of the most energy-efficient approaches to heat and cool your Charleston residence. That’s because they move warm or cold air, rather than making it. But not everyone has been able to enjoy this energy-saving technology.

At one time, heat pumps were only suggested for temperate areas, as they lose efficiency when temperatures were around or below freezing. When the heat pump couldn’t match demand, the heating system would then rely on pricier electric heat as a secondary heat source to keep the residence cozy.

With new technology, heat pump systems are now recommended for cold locations. Most can run properly at much colder temperatures, although some could still need a backup heating system if temperatures dip too low. But it’s crucial to know that today’s emergency heating systems can also be more energy-efficient than previously.

We’ll discuss the different kinds of heat pumps so you can choose the ideal one for your house.

Air Source Heat Pumps: Ideal for Moderate Locations

Air source heat pumps are the most installed kind of heat pump. They use an outdoor unit and an indoor air handler. These systems move heat from either the indoor air during the warmer weather, or outside air during the winter, keeping you cozy throughout the seasons.

With updates in heat pump technology, these systems can now be installed in a full range of climates. But it’s important to be aware that you will likely have to have an auxiliary source of heat if temperatures go under 10 degrees Fahrenheit. This might include a dual-fuel system with a gas furnace. Heating alternates between the two to provide the most energy-efficient heating comfort across your house.

Due to the demand for dual-fuel systems in cold climates, air source heat pumps are best suited for areas without wide temperature swings and lower heating demands.

Mini-Split Heat Pumps: Best for Areas Without Ductwork in Chillier Climates

Mini-split heat pumps are one of the most flexible types of heat pumps because they don’t need ductwork. This means you can install them just about anywhere in your home, like a garage or addition. They’re also very energy efficient, with most achieving ENERGY STAR® status.

Mini-splits use an outdoor unit that joins to as many as four quiet, slim 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 space.

Outdoor air on even the chilliest days holds some heat that your ductless heat pump can use and send indoors. Depending on the type you choose, some cold-weather mini-split heat pumps from Mitsubishi can operate in temperatures as cold as -13°F.

Geothermal Heat Pumps: Ideal for Harsh Temperatures and Large Yards

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

Geothermal doesn’t make a lot of noise and can last for many years—approximately 25 years for the indoor unit and about 50 years for the loop.

It doesn’t require a lot of maintenance and is great if you are in a climate with big temperature swings. In most instances, geothermal does not need a secondary heating system.

However, you’ll need a good amount of space and the right makeup of soil to install the underground loops. It’s also important to note that installation can run around $20,000–$25,000 for a 2,500-square foot residence. Although the installation cost is more expensive, continuing energy savings might help the unit pay for itself over time.

As geothermal is so efficient, using it may make you eligible for federal tax credits and other rebates from your local energy provider.
