Do heat pumps work in East Bay winters?
Yes, with honest sizing. The “dies at 40°F” line is old marketing.
A 38°F night in Lafayette is not a polar vortex. Modern units are built for this. We still verify the defrost board on the install.
East Bay winters rarely drop below the range a modern heat pump handles. Ice on the outdoor unit can be a normal defrost cycle — or a failing sensor.
