Winter Noise with Heat Pump

Derek Cole explains why heat pumps make noise and behave oddly in cold weather. The defrost cycle switches the system to air-conditioning mode to melt frost on the outdoor coil, which stops the fan, releases steam, and triggers indoor heat strips that may feel like a cooler breeze. These actions are normal and automatically controlled by your thermostat.

With this kind of weather and with these kind of temperatures and conditions, your heat pump is going through what is called a defrost cycle. It actually reverses, uh, what you think's happening. So you have to sit on heat, you have to sit on you whatever temperature you have to sit on, um, and it times out or senses on the outdoor cold that, hey, I need to defrost this coil, I'm getting too much frost on it, or I might have some ice on it. Something is telling me I need to go through this cycle. It could be a timer, it could be a sensor, depending on your setup, depends on what's there. So what happens is it actually switches to AC mode from heating mode. So there, it's actually blowing the warm air that's in the house back outside to melt that frost on that coil. But your heat strips come on inside so you don't get too cold. Uh, you might feel a slight cooler breeze or, you know, a slight cooler feeling when it's in that mode, but it's in AC mode to burn that frost off. But the heat strips will come on to keep it warm inside. So when that happens, that is normal, that's fine. Uh, you'll also see probably some steam coming from the outdoor unit. The outdoor fan is not going to be turning when it goes through that cycle because again, the only, the only heat you have at that point is the backup heat or the auxiliary heat. So when it's in defrost cycle, you're not going to have the outdoor fan running, but that's completely normal. So nothing to worry about there. But also with these temperatures, your backup strip heat, it's going to run, uh, if you've got your thermostat set to a, you know, the temperature, whatever temperature you think is good for you, you know, whether it be 68, 72, I don't know, it's up to you. But with these kind of temperatures outside and this kind of weather, it does need some help to get to that temperature. So we'll bring the heat strips on when it gets to the point that it needs a little bit of help. Now, the system, the thermostat, it knows when that is, okay? So there's nothing you have to worry about. It will just bring it on as needed. But down below this video, I included a couple links to a couple of free PDFs. It's free of charge, no obligation, just name and email. But the the top 3 questions asked. I get— also include the top 10 maintenance tips for heating. So both these are free, both are PDFs. You can download them, save them, print them, uh, whatever you like. But hopefully that'll answer some more of your questions and help you through this process. But with this weather Uh, and heat pumps, I mean, you're gonna have defrost, you're gonna have, uh, the auxiliary backup heaters come on to, to help. So, uh, if you need us, call us or text me. A few people, uh, took advantage of that last weekend. Uh, you can text me 904-635-811. 463-5811. If you have a question, text me and we'll get you the answer.
