Important Heat Pump Information
A heat pump can still operate in cold weather, although its efficiency will decrease significantly as temperatures drop, meaning it will need to work harder to produce the same amount of heat. In extremely cold conditions, most heat pumps may require a backup heating source to maintain comfortable temperatures, but modern “cold climate” heat pumps can function effectively with proper installation and selection.
Key points about heat pumps in cold weather:
- Reduced efficiency:
Heat pumps use more energy when it’s cold outside to keep your home warm.
- Cold climate heat pumps:
Special heat pumps are made to work better in cold weather.
- Backup heating:
In very cold weather, you may need an extra heater to help the heat pump keep your home warm.
- Defrost cycle:
Heat pumps sometimes switch to cooling mode to melt ice that can build up outside in freezing temperatures.
Important factors to consider:
- Proper installation:
Correct installation is crucial for optimal performance in cold weather, including selecting the right size heat pump for your home and climate.
- Maintenance:
Regular maintenance is important to ensure your heat pump operates efficiently in cold conditions, including cleaning the outdoor unit and checking refrigerant levels.
Temperature limitations:
While cold climate heat pumps can operate in very low temperatures, their efficiency will still decline significantly below a certain point
