What Climates Do Heat Pumps Work In?

A heat pump is one of the most energy-efficient ways to heat and cool your Tempe home. That’s because they move warm or cold air, as opposed to producing it. But not all homeowners have been able to use this energy-saving technology.

Previously, heat pumps were only advised for warmer locations, as they were less effective when temperatures were close to or below freezing. When the heat pump couldn’t provide the desired temperature, the heating system would then switch to pricier electric heat as a secondary heat source to keep the home cozy.

With updated technology, heat pump systems are now ideal for chillier locations. Most can operate smoothly at much colder temperatures, although some might still need a backup heating system if temperatures dip too low. But it’s crucial to be aware that today’s emergency heating solutions can also be more energy-efficient than before.

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

Air Source Heat Pumps: Right for Moderate Areas

Air source heat pumps are the most installed style of heat pump. They have an outdoor unit and an indoor air handler. These systems move heat from either the indoor air during the warm weather, or outside air during the winter, keeping you comfortable no matter the weather.

With advances in heat pump technology, these systems can now be added in a large range of climates. But it’s important to know that you will probably require a secondary source of warmth if temperatures get colder than 10 degrees Fahrenheit. This might entail a dual-fuel system with a gas furnace. Heating switches between the two to provide the most energy-efficient heating comfort all over your house.

Due to the need for dual-fuel systems in chillier climates, air source heat pumps are recommended locations without large temperature swings and lower heating requirements.

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

Mini-split heat pumps are one of the most versatile styles of heat pumps because they don’t need ductwork. This means you can add them just about anyplace in your home, like a garage or addition. They’re also extremely energy efficient, with many achieving ENERGY STAR® designation.

Mini-splits work with an outdoor unit that links to as many as four quiet, low-profile indoor units mounted on 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 coldest days holds some heat that your ductless heat pump can use and move indoors. Depending on the type you go with, some cold-weather mini-split heat pumps from Mitsubishi can work in temperatures as frigid as -13°F.

Geothermal Heat Pumps: Best for Extreme Temperatures and Large Yards

Geothermal heat pumps take advantage of stable subsurface temperatures to drastically reduce your heating and cooling bills, usually by 25%–50%! These systems have subterranean pipes to transfer heat to and from your home.

Geothermal isn’t disruptive and can work a long time—around 25 years for the indoor unit and about 50 years for the loop.

It doesn’t require a lot of upkeep and is best if you are in an extreme climate. A lot of the time, geothermal does not have to have a secondary heating system.

However, you’ll require a good amount of space and the correct makeup of soil to put in the underground loops. You should also know that installation costs around $20,000–$25,000 for a 2,500-square foot residence. Although the installation cost is pricier, ongoing energy savings may help the equipment pay for itself over time.

Because geothermal saves a lot of energy, adding it may make you eligible for federal tax credits and other rebates from your community energy provider.
