What Temperatures Do Heat Pumps Work In?

A heat pump is one of the most energy-efficient approaches to heat and cool your San Antonio home. 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 recommended for moderate locations, since they lose efficiency when temperatures were near or below freezing. When the heat pump couldn’t keep up, the heating system would then switch to more expensive electric heat as a backup heat source to keep the home comfy.

With modern technology, heat pump systems are now recommended for cold areas. Most can operate smoothly at much colder temperatures, although some could still need an auxiliary heating system if temperatures dip too low. But it’s important to realize that today’s emergency heating equipment can also be more energy-efficient than before.

We’ll go over the varying types of heat pumps so you can select the best one for your residence.

Air Source Heat Pumps: Best for Moderate Climates

Air source heat pumps are the most used 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 warmer weather, or outside air during cold weather, keeping you comfy throughout the seasons.

With updates in heat pump technology, these systems can now be added in a wide range of climates. But it’s important to be aware that you will likely require an emergency source of heat if temperatures get colder than 10 degrees Fahrenheit. This may involve a dual-fuel system with a gas furnace. Heating changes between the two to give the most energy-efficient heating comfort across your residence.

Because of the requirement for dual-fuel systems in colder climates, air source heat pumps are ideal locales without wide temperature swings and more moderate heating demands.

Mini-Split Heat Pumps: Recommended for Rooms Without Ductwork in Cold Climates

Mini-split heat pumps are one of the most flexible kinds of heat pumps because they don’t have to have ductwork. This means you can install them just about anyplace in your residence, including a garage or addition. They’re also extremely energy efficient, with most earning ENERGY STAR® recognition.

Mini-splits have an outdoor unit that connects to as many as four quiet, low-profile indoor units attached to your wall or ceiling. This allows you to have zoned heating and cooling, with accurate temperature control in each room.

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

Geothermal Heat Pumps: Ideal for Extreme Temperatures and Large Yards

Geothermal heat pumps take advantage of steady underground temperatures to tremendously reduce your heating and cooling expenses, typically by 25%–50%! These systems use buried pipes to shift heat to and from your house.

Geothermal is quiet and can work for years—about 25 years for the indoor unit and around 50 years for the loop.

It doesn’t require a lot of service and is best if you live in an extreme climate. In most instances, geothermal does not require an auxiliary heating system.

However, you’ll require a lot of space and the correct type of soil to install the underground loops. You should also know that installation can run around $20,000–$25,000 for a 2,500-square foot house. Although the installation cost is high, long-term energy savings could help the equipment pay for itself over the years.

Because geothermal saves a lot of energy, using it might make you eligible for federal tax credits and other rebates from your area energy provider.
