Heat Pump Basics for Georgia Homeowners
If you live in the Columbus area, there is a good chance your cooling system is a heat pump. The same outdoor unit that cools your home in July also heats it in January by reversing the direction refrigerant flows.
Heat pumps are efficient here precisely because winters are mild, but they behave differently enough from a furnace-and-AC setup that normal operation sometimes gets mistaken for a problem.
Cooling mode is identical to a standard AC
In summer, a heat pump does exactly what an air conditioner does: absorbs heat indoors, rejects it outdoors. Every cooling symptom on this site applies equally to heat pumps.
Heating mode reverses the flow
A reversing valve switches refrigerant direction so the outdoor coil absorbs heat from cold outside air and the indoor coil releases it. There is usable heat in outdoor air well below freezing.
Why heat pump air feels cooler in winter
Supply air from a heat pump typically runs in the mid-nineties rather than the 120°F-plus of a gas furnace. It heats the home effectively but can feel less warm to the hand. This is normal.
Defrost cycles are normal
On cold damp days the outdoor coil frosts, and the system periodically reverses briefly to melt it. Steam rising from the outdoor unit during defrost is expected, not a malfunction.
Auxiliary heat should be occasional
Electric strip heat supplements the heat pump during very cold weather or after a large setback. If auxiliary heat runs frequently in mild weather — or at all during summer — something is wrong and the power bill will show it.
Thermostat configuration matters
Heat pumps need the thermostat configured for the correct equipment type and changeover behavior. Incorrect setup after a DIY smart thermostat installation is a common cause of strange heating and cooling behavior.
Frequently Asked Questions
Are heat pumps a good fit for the Columbus climate?
Yes. Mild winters mean a heat pump covers most heating hours efficiently, and the same equipment provides cooling through the long, hot summer.
