Zion Mitchell – What Causes Smoke from a Heat Strip?

HVAC Technical Academy
Sanford, Florida
May–June 2026 Session

Speaker: Zion Mitchell

Hello, my name is Zion Mitchell and I’m here with HVAC Technical Academy and Miss Smith gave me a call and said that she has a problem with smoke coming out of her heat strip and she was worried and I gave her a good rundown. I told her that the only way a heat strip could, like, you know, the problem could be why smoke could be coming out is because dust particles, depending on how long we used it for, could get inside the heat and it could cause it to smoke. So, that calmed Miss Smith down pretty good.

But also, I want to explain what a heat strip is. A heat strip is an electrical element that’s in your air handler. Basically, let’s say your thermostat wants to call for emergency heat, it goes through the heat strips causing the heat strips to heat up. Fun fact, if it’s a straight cool, it’s a primary. And if it’s a heat pump, it’s an emergency.

So, we took this out. Oops. Sorry. We took this out, tested it, and found out we have to put in a new one. This one is no good. So, we’re going to go put in a new one.

All right. All right. Now, we got to put in a new one. Oh, wow. Look, there’s a new one. So, what we do? All right, I’m going to give Miss Smith a new heat pump, so we should have no worries.

All right, put this all the way back here. All right, reconnect this. All right, reconnect this. All good. And we are up and rolling.

Thank you so much for you guys watching and hope you guys have a good day.
