What happens to a heat pump as it gets colder?
A heat pump moves heat from the outdoor air into your home. As the outdoor temperature drops, there's less heat to move and the system works harder, so heating output falls. That's normal, and it's why the cold days have to be part of the plan from the start.
How are the coldest days covered?
- Backup heat built into the system.
- Dual fuel: pairing the heat pump with a gas furnace that takes over in colder weather.
- Equipment selected for the home's actual heating needs, not a rule of thumb.
Where do inverter heat pumps fit?
An inverter heat pump varies its speed to match the demand instead of switching between full power and off. That modulation can mean more consistent temperatures and quieter operation. Whether it's the right fit depends on the home and your budget; it's one option among several.
