Why Is There a Burning Smell Coming Out of My AC Vents? | DeZiel Heating & AC

If you’ve turned on your AC unit recently and smelled something burning, you may be wondering what’s happening. Luckily, this is a fairly common thing, and somewhat easy to diagnose. Here are three reasons:

Why Is There a Burning Smell Coming Out of My AC Vents
  1. There is a fire in your home, and the unit is circulating air from where the fire is. 
  2. Your heater is burning-off dust.
  3. Something in your AC unit is overheating. 

First and foremost, if you think it may be number one, stop reading this, evacuate your home, and call 911. This, of course, is a more serious issue. 

If you haven’t turned on your heat recently, number two can probably be eliminated. That leaves number three as the culprit (assuming there’s no fire in your home). 

If your AC unit is in cooling mode, and you smell burning, shut it off immediately. Running it while something is wrong will create bigger, more expensive issues for you. You’ll need to call an experienced AC repairman. In the meantime, here are some reasons your unit could be overheating.

Overheating Motor

In the inside part of your AC unit, there’s a fan that moves the air around your home. The bearings in the fan can break down, causing the motor that powers the fan to overheat. If that happens, you’ll smell a burning smell. 

Bad Capacitor

The capacitor helps the motor run. When it has an issue, the motor can overheat, and create the burning smell you may be encountering.

Electrical Problems

It’s also possible that there are other electrical problems in your unit causing other components to overheat. A trained professional will be able to figure out what the issue is.
