What Temperatures Do Heat Pumps Work In?

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

At one time, heat pumps were only recommended for moderate climates, because they were less effective when temperatures were around or below freezing. When the heat pump couldn’t meet demand, the heating system would then trigger more costly electric heat as a backup heat source to keep the residence cozy.

With new technology, heat pump systems are now recommended for cold locations. Most can operate properly at much lower temperatures, although some may still need a backup heating system if temperatures dip too low. But it’s crucial to be aware that today’s auxiliary 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 Areas

Air source heat pumps are the most common type of heat pump. They have an outdoor unit and an indoor air handler. These systems transfer heat from either the indoor air during the warm weather, or outside air during colder weather, keeping you comfy throughout the seasons.

With changes in heat pump technology, these systems can now be installed in a large range of climates. But keep in mind that you will probably have to have a secondary source of heat if temperatures get colder than 10 degrees Fahrenheit. This could include a dual-fuel system with a gas furnace. Heating changes between the two to give the most energy-efficient heating comfort across your residence.

As a result of the demand for dual-fuel systems in colder climates, air source heat pumps are recommended locales without big temperature changes and more moderate heating requirements.

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

Mini-split heat pumps are one of the most versatile styles of heat pumps since they don’t require ductwork. This means you can install them just about in any room in your home, such as a garage or addition. They’re also extremely energy efficient, with most earning ENERGY STAR® status.

Mini-splits work with an outdoor unit that connects to as many as four quiet, small indoor units mounted on your wall or ceiling. This gives you the ability to have zoned heating and cooling, with accurate temperature control in each room.

Outdoor air on even the chilliest days has some heat that your ductless heat pump can catch and move indoors. Depending on the model you go with, some cold-weather mini-split heat pumps from Mitsubishi can run in temperatures as low as -13°F.

Geothermal Heat Pumps: Ideal for Harsh Temperatures and Big Yards

Geothermal heat pumps take advantage of stable underground temperatures to significantly reduce your heating and cooling costs, often by 25%–50%! These systems use underground pipes to move heat to and from your house.

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

It doesn’t require a lot of maintenance and is best if you reside 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 kind of soil to install the underground loops. It’s also important to note that installation costs around $20,000–$25,000 for a 2,500-square foot home. Although the installation cost is high, continuing energy savings could help the system pay for itself over the years.

Because geothermal is so efficient, installing it may make you eligible for federal tax credits and other rebates from your area energy provider.
