Heat pump performance in cold weather
Every air-source heat pump loses some capacity and efficiency as outdoor temperatures fall. Performance at your coldest temperatures varies by model and must be checked against published manufacturer data.
Equipment we install
Selected for your home. Designed to work together.
What to expect in winter
- Lower output as temperatures fall
- Periodic defrost cycles
- Longer, steady run times — normal for variable-speed systems
- Backup heat engaging on the coldest days, if designed that way
Our approach to claims
We do not quote a single temperature a heat pump 'works to'. We compare the specific model's published capacity data to your home's heat loss.
