So you’ve turned on your heat and everything is running smoothly. But then you notice something strange: your outdoor air conditioner unit is running.
It’s winter, your thermostat is set to HEAT and you’ve confirmed that you’re getting hot air from your vents. So why the heck is your A/C running?
Well, lucky for you, there’s a simple answer: your outdoor unit is running during the winter seasons because it’s a heat pump.
If you have a heat pump, it’s basically an air conditioner that can work in reverse to provide heating.
And the best part? Because you live in Arizona with mild winters, your heat pump saves you up to 50% in electricity usage compared to electric furnaces or baseboard heating.
Well, a heat pump moves heat instead of creating it (like a furnace does). Compared to electric furnaces, heat pumps use relatively little electricity to complete this “heat transfer” process.
During the summer, a heat pump uses refrigerant coils to absorb heat from inside your home and dump it outdoors. During the winter, that same unit can reverse the flow of refrigerant in order to absorb heat from the outdoor air and move it into your home.

Note: You may also notice steam coming from your outdoor heat pump unit during the winter. But don’t be alarmed, this is normal. It’s just your heat pump going through a “defrost mode”. Learn more about heat pump defrost cycles here.
Still not convinced that you have a heat pump? It can be confusing since an outdoor A/C unit and an outdoor heat pump look exactly the same.
Two ways you can tell that you have a heat pump:
The brass reversing valve inside the condenser differentiates a heat pump from an A/C unit.
Now that you know your heat pump works non-stop throughout the year, you’ll want to be sure that you’re giving it the TLC it deserves.
We suggest getting your heat pump maintenanced once before the cooling season and once before the heating season.
Some common heat pump problems that maintenance can prevent include:
