What Temperatures Do Heat Pumps Work In?

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

In the past, heat pumps were only suggested for temperate locations, since they weren’t as effective when temperatures were near or below freezing. When the heat pump couldn’t meet demand, the heating system would then rely on more costly electric heat as a secondary heat source to keep the house comfy. 

With new technology, heat pump systems are now ideal for cold areas. Most can run well at much colder temperatures, although some might still need a secondary heating system if temperatures get too cold. But it’s crucial to know that today’s backup heating solutions can also be more energy-efficient than previously. 

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

Air Source Heat Pumps: Ideal for Moderate Climates 

Air source heat pumps are the most used kind of heat pump. They have an outdoor unit and an indoor air handler. These systems move heat from either the indoor air during the warmer weather, or outside air during the winter, 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 it’s important to know that you will likely need an auxiliary source of warmth if temperatures get colder than 10 degrees Fahrenheit. This may include a dual-fuel system with a gas furnace. Heating switches between the two to deliver the most energy-efficient heating comfort across your house. 

Because of the requirement for dual-fuel systems in chillier climates, air source heat pumps are best suited for areas without big temperature swings and lower heating requirements. 

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

Mini-split heat pumps are one of the most flexible types of heat pumps as they don’t need ductwork. This means you can install them just about anyplace in your home, such as a garage or addition. They’re also extremely energy efficient, with the majority earning ENERGY STAR® recognition. 

Mini-splits have an outdoor unit that links to as many as four quiet, slim indoor units attached to your wall or ceiling. This allows you to have zoned heating and cooling, with exact temperature control in each space. 

Outdoor air on even the chilliest days has some heat that your ductless heat pump can use and move 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 Harsh Temperatures and Big Yards 

Geothermal heat pumps take advantage of balanced subterranean temperatures to significantly reduce your heating and cooling costs, typically by 25%–50%! These systems rely on buried pipes to move heat to and from your house. 

Geothermal doesn’t make a lot of noise and can work for many years—around 25 years for the indoor unit and around 50 years for the loop. 

It doesn’t need a lot of service and is ideal if you are in a climate with big temperature swings. In most instances, geothermal does not need an auxiliary heating system. 

However, you’ll need a good amount of space and the correct kind of soil to install the underground loops. You should also be aware that installation costs around $20,000–$25,000 for a 2,500-square foot house. Although the installation cost is high, lifelong energy savings might help the equipment pay for itself as time passes. 

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