How a heat pump works
In summer it moves heat out of your house, exactly like a central AC. In winter it reverses and moves heat from the outdoor air into the house. Because it moves heat instead of making it, it can be very efficient. Source: DOE Energy Saver: heat pump systems.
Why heat pumps suit the Sacramento area
- Hot summers mean you need good cooling anyway.
- Mild winters are easy work for a heat pump.
- Local utilities, SMUD and PG&E, have offered heat pump incentives. Check current programs before you buy.
Signs a heat pump needs repair
Stuck in one mode
Heats but won't cool, or the reverse, can point to a reversing valve or control problem.
Heavy ice that won't clear
The defrost cycle may not be working.
Backup heat running constantly
Higher bills and "aux heat" on the thermostat a lot can mean the heat pump isn't keeping up.
Weak airflow
Check the filter first, then have the blower and coil inspected.
FAQ
Do heat pumps work in Sacramento winters?
Yes. Sacramento winters are mild, and modern heat pumps are designed to heat efficiently in much colder climates. Some homes keep a gas furnace as backup (a dual-fuel setup).
Why is my heat pump steaming outside in winter?
That's usually a normal defrost cycle, which melts frost off the outdoor coil. If it frosts heavily and never clears, have it checked.
Can a heat pump replace my AC and furnace?
Often, yes. A contractor should check whether your electrical panel and ducts can support it.
