What Temps Do Heat Pumps Work In?

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

At one time, heat pumps were only advised for temperate areas, because 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 trigger pricier electric heat as a secondary heat source to keep the home comfy.

With new technology, heat pump systems are now ideal for cold locations. Most can work well at much chillier temperatures, although some might still need a backup heating system if temperatures get too cold. But it’s essential to realize that today’s emergency heating systems can also be more energy-efficient than before.

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

Air Source Heat Pumps: Best for Moderate Areas

Air source heat pumps are the most installed type of heat pump. They use 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 year-round.

With advances in heat pump technology, these systems can now be used in a large range of climates. But keep in mind that you will likely have to have a backup source of warmth if temperatures go under 10 degrees Fahrenheit. This could include a dual-fuel system with a gas furnace. Heating alternates between the two to provide the most energy-efficient heating comfort throughout your home.

Due to the demand for dual-fuel systems in cold climates, air source heat pumps are recommended areas without large temperature changes and lower heating requirements.

Mini-Split Heat Pumps: Ideal for Spaces Without Ductwork in Chillier Climates

Mini-split heat pumps are one of the most adaptable types of heat pumps because they don’t require ductwork. This means you can install them just about anyplace in your home, such as a garage or addition. They’re also very energy efficient, with many receiving ENERGY STAR® status.

Mini-splits use an outdoor unit that links to as many as four quiet, low-profile indoor units attached to your wall or ceiling. This gives you the ability to have zoned heating and cooling, with precise temperature control in each space.

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

Geothermal Heat Pumps: Ideal for Extreme Temperatures and Large Yards

Geothermal heat pumps take advantage of stable subsurface temperatures to significantly reduce your heating and cooling bills, often by 25%–50%! These systems rely on subterranean pipes to shift heat to and from your house.

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

It doesn’t have to have a lot of upkeep and is best if you live in a climate with big temperature swings. In most instances, geothermal does not require an auxiliary heating system.

However, you’ll have to have a good amount of space and the ideal type of soil to put in the underground loops. It’s also important to note 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 might help the system pay for itself as time passes.

Since geothermal conserves a lot of energy, adding it may make you eligible for federal tax credits and other rebates from your area energy provider.
