What Temperatures Do Heat Pumps Work In?

A heat pump is one of the most energy-efficient methods to heat and cool your Houston house. That’s since they move warm or cold air, instead of 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 warmer locations, as they weren’t as effective when temperatures were around or below freezing. When the heat pump couldn’t meet demand, the heating system would then rely on pricier electric heat as an emergency heat source to keep the residence comfy.

With updated technology, heat pump systems are now ideal for cold locations. Most can run properly at much lower temperatures, although some might still need a secondary heating system if temperatures dip too low. But it’s essential to be aware that today’s auxiliary heating systems can also be more energy-efficient than before.

We’ll review the differing styles of heat pumps so you can select the right one for your residence.

Air Source Heat Pumps: Best for Moderate Areas

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 transfer heat from either the indoor air during the warmer weather, or outside air during the winter, keeping you comfortable throughout the seasons.

With changes in heat pump technology, these systems can now be used in a full range of climates. But it’s important to be aware that you will likely require a secondary source of warmth if temperatures go under 10 degrees Fahrenheit. This may involve a dual-fuel system with a gas furnace. Heating changes between the two to deliver the most energy-efficient heating comfort throughout your residence.

Due to the demand for dual-fuel systems in chillier climates, air source heat pumps are best suited for areas without large temperature changes and more moderate heating requirements.

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

Mini-split heat pumps are one of the most versatile kinds of heat pumps since 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 extremely energy efficient, with most achieving ENERGY STAR® status.

Mini-splits have 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 area.

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

Geothermal Heat Pumps: Best for Extreme Temperatures and Spacious Yards

Geothermal heat pumps take advantage of even subsurface temperatures to drastically reduce your heating and cooling expenses, usually by 25%–50%! These systems rely on subterranean pipes to shift heat to and from your residence.

Geothermal is quiet and can last for many years—approximately 25 years for the indoor unit and around 50 years for the loop.

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

However, you’ll have to have a lot of space and the right makeup 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, continuing energy savings may help the system pay for itself over time.

Because geothermal is so efficient, using it might entitle you to federal tax credits and other rebates from your local energy provider.
