What Temps Do Heat Pumps Work In?

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

At one time, heat pumps were only advised for warmer areas, since they lose efficiency when temperatures were around or below freezing. When the heat pump couldn’t provide the desired temperature, the heating system would then switch to more costly electric heat as a secondary heat source to keep the home cozy.

With updated technology, heat pump systems are now recommended for cold areas. Most can work smoothly at much colder temperatures, although some might still need a backup heating system if temperatures get too cold. But it’s essential to note that today’s backup heating equipment can also be more energy-efficient than before.

We’ll go over the varying kinds of heat pumps so you can choose the best one for your house.

Air Source Heat Pumps: Best for Moderate Areas

Air source heat pumps are the most common type of heat pump. They rely on an outdoor unit and an indoor air handler. These systems shift heat from either the indoor air during the summer, or outside air during cold weather, keeping you comfy year-round.

With advances in heat pump technology, these systems can now be used in a large range of climates. But you should know that you will likely have to have an emergency source of heating if temperatures get colder than 10 degrees Fahrenheit. This might entail a dual-fuel system with a gas furnace. Heating alternates between the two to give the most energy-efficient heating comfort all over your residence.

Because of the requirement for dual-fuel systems in chillier climates, air source heat pumps are best suited for locales without wide temperature changes and decreased heating requirements.

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

Mini-split heat pumps are one of the most adaptable styles of heat pumps as they don’t require ductwork. This means you can use them just about anywhere in your home, including a garage or addition. They’re also highly energy efficient, with most earning ENERGY STAR® recognition.

Mini-splits use an outdoor unit that connects to as many as four quiet, slim indoor units mounted on your wall or ceiling. This allows you to have zoned heating and cooling, with precise temperature control in each space.

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

Geothermal Heat Pumps: Ideal for Extreme Temperatures and Large Yards

Geothermal heat pumps take advantage of steady subsurface temperatures to tremendously decrease your heating and cooling costs, typically by 25%–50%! These systems have subterranean pipes to shift heat to and from your home.

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

It doesn’t require a lot of maintenance and is great if you are in a climate where temperatures vary greatly. A lot of the time, geothermal does not have to have a secondary heating system.

However, you’ll need a large amount of space and the ideal makeup of soil to put in the underground loops. It’s also important to note that installation is around $20,000–$25,000 for a 2,500-square foot residence. Although the installation cost is more expensive, long-term energy savings may help the system pay for itself as time passes.

As geothermal is so efficient, using it might qualify you for federal tax credits and other rebates from your community energy provider.
