378. Heat Pumps Around Here
28 Jan 2026 · 6 min
Derek Cole explains how heat pumps extract heat from outside air and why they need electric backup heat when temperatures drop below around 40°F or during defrost cycles. Those cycles can trigger noise and steam as the system briefly switches to cooling mode to melt frost buildup.

Thanks again for listening. And let's begin. If you have a heat pump, your backup heat will come on. I know sometimes that kind of freaks some, some folks out when the backup heat is on because it's, you know, it's straight electricity is running up your bill. But really the backup heat serves two purposes. Mainly is to supplement the heat pump. So in this area, when in this area, if you have a heat pump when it gets below 40 degrees, it really starts to need help reaching the set point in your house. So if you got it on 72, it needs help getting there because it's so cool outside, so cold that you need something to add to it. That's why you have the backup heat, the strip heaters, for that reason. The other main reason you have the bag of heat is because of a defrost cycle. So what happens when you have a heat pump and it's in heating mode? It's actually extracting the heat from outside. So when that happens, frost builds up on the coals. So at some point it needs to get rid of that frost. So what happens is it actually reverses the flow of refrigerant and turns into AC mode. So in AC mode, you're taking the heat outside from the house outside. So when that happens, it's going to melt off that frost. So your backup heat comes on because you know you don't want to be cold inside. So when that happens, your backup heat will come on as well. And what's really, what's, what's really strange is it makes a very loud noise when it switches over to the defrost cycle. So usually you hear the loud noise, you look outside, you see your heat pump, steam's coming out from it, so you think something's wrong when it may be the defrost cycle. So I just been want you to freak out. It is going to happen with these, you know, cooler, cooler days, cold mornings, cold nights, the steam will happen from the heat pump, the backup heat, your secondary heat will come on to supplement all that.
