Latest From Our HVAC Experts
Do Heat Pumps Work in Cold Weather?
Yes — modern heat pumps heat in cold weather, often well below freezing. Capacity and efficiency change as it gets colder, so here’s what actually matters: equipment selection, defrost, backup heat, and matching the system to your home.
Should I Turn My Heat Pump Down at Night or Leave It Alone?
“Turn it down at night” and “never touch a heat pump” are both too simple. A modest setback can save energy — but an aggressive morning recovery can trigger pricey backup heat. Here’s how to find the right strategy for your home.
What Temperature Should I Set My Heat Pump in Winter
There’s no magic heat-pump number. Around 68°F is a good starting point — then adjust for comfort, avoid big swings that trigger expensive backup heat, and let variable-speed equipment run the way it’s designed to.
Why Does My Heat Pump Keep Switching to Auxiliary Heat?
AUX HEAT keeps popping up on your thermostat? It’s normal backup heat helping the heat pump under certain conditions — but constant, unexplained AUX can spike your bill. Here’s what triggers it and when it signals a problem.
Is My Heat Pump Smoking? Why Steam Comes From a Heat Pump
That “smoke” rising from your heat pump on a cold morning is usually steam — the normal defrost cycle melting frost off the outdoor coil. Here’s how to tell normal defrost from an actual problem.

Replacing your AC in Southern California? A heat pump cools like a central AC and heats too — so it’s worth comparing. Here’s how they differ on efficiency, ductwork, furnace compatibility, electrical and cost, and when each makes sense.
Central Heat Pump vs. Mini Split: Which Is Better?
A mini split is usually a heat pump too — the real question is how the heating and cooling gets distributed. Here’s how central ducted and ductless systems compare on comfort, zoning, ductwork, efficiency, cost and appearance, and when a hybrid of both wins.
Why Does My Heat Pump Keep Turning On and Off?
A heat pump cycling on and off every few minutes is “short cycling” — and it can come from something as simple as a dirty filter or as different as oversizing, a pressure safety or a float switch. Here’s how to tell what’s really going on.
