Derek Cole explains why homeowners shouldn't switch heat pumps to auxiliary heat in cold weather. The outdoor fan stops and electric heat strips kick in, which looks like a malfunction but is normal during defrost cycles. Leaving it on auto lets the system handle defrost on its own.
You have a heat pump and it's going on auxiliary only. So the mistake some folks make is they've been told that it's more efficient when it's cold outside to turn the thermostat to auxiliary heat or emergency heat and not heat pump heat. So when it goes into that mode, the outdoor fan will stop running outside, and the indoor fan and the strip piece will run inside to keep you warm. That'll also happen when he's going into a defrost cycle. So if you're. If you haven't done that and just have it on heat, your heat pump will run. And when it goes in a defrost, that fan will stop, the electric heat will come on, and it will defrost that coral, which you'll see that steaming coming up when it's really cold in the morning. So that's normal.
