A heat pump may run for hours during a cold Leetsdale night. That can seem unusual if you’re used to a furnace that turns on, blows hot air, and shuts off. Longer runs are often part of how a heat pump keeps a steady temperature.
But if your home keeps getting colder, it’s worth finding out why. Here’s what cold weather does to a heat pump and when the system may need backup heat or repair.
How Heat Pumps Handle Cold
Even on a cold day, a heat pump can pull heat from the outdoor air and bring it inside. The air coming from your vents may not feel as hot as furnace air, but it can still warm your home.
When it gets colder, the heat pump may run longer. It may also stop briefly to clear frost from the outdoor unit. Both can be normal. If your home keeps getting colder, the system may need backup heat or repair.
Heat Pump Efficiency In Ohio
Cleveland winters bring freezing temperatures, snow, and stretches of bitter cold. A heat pump that handles a mild winter day well may need to run longer during a cold snap. Its heating output can also drop as outdoor temperatures fall.
Cold-climate models are built to perform better at low temperatures than many older heat pumps. If you’re considering a new system, W.F. Hann & Sons can review your home’s heating needs and explain which heat pump options make sense for the Cleveland area. A properly chosen system may also need backup heat for the coldest days.
When Heat Pumps Lose Efficiency
No single temperature makes all heat pumps less efficient. It depends on the system and the home. Your heat pump may use backup heat during a cold spell, and that doesn’t always mean something is wrong.
If it runs for hours, but your home keeps getting colder, or the backup heat turns on more often than usual, schedule a checkup.
Factors That Affect Cold-Weather Performance
Several things affect how well a heat pump heats your home:
- Outdoor temperature: Colder air makes it harder for the system to move enough heat indoors.
- System type: A cold-climate model can perform better in low temperatures than a system designed mainly for milder weather.
- Equipment age and condition: Worn parts or a system that needs repair may struggle sooner.
- Sizing: A heat pump that’s too small for the home’s heating needs may struggle to keep up.
- Maintenance and airflow: Dirty filters, blocked vents, and equipment problems can reduce heating performance.
Maintaining Cold-Weather Heat Pump Performance
Before winter, ask a technician to check that the heat pump heats your home and switches to backup heat when needed. During the season, change dirty filters, leave vents open, and clear snow from around the outdoor unit.
Watch for rooms that stay cold, weak airflow, or sounds you haven’t heard before. Frost on the outdoor unit can be normal because the system stops briefly to melt it. If thick ice stays on the unit, have a technician check it. If your home still isn’t getting warm, W.F. Hann & Sons offers heat pump repair in the Leetsdale area.

Frequently Asked Questions
Do Heat Pumps Work Below Freezing?
Yes. Heat pumps can still warm your home when it’s below freezing. How well they work depends on the model, how cold it is, and your home.
When Do Heat Pumps Become Inefficient?
There’s no single temperature for every heat pump. As it gets colder, the system generally has to work harder. It may need backup heat to keep your home at the temperature you set.
Should I Turn Off My Heat Pump In Extreme Cold?
Usually, no. Leave it in heating mode so its controls can turn on backup heat when needed. If your home keeps getting colder or the system stops heating, schedule service.
