What Stinks? 5 Reasons Your AC Smells Bad

AC Smells Bad

Your air conditioner should keep your home feeling cool and fresh. But even if your house is very comfortable temperature-wise, if there’s an odd odor coming from your vents, your house isn’t going to feel very fresh. If your AC smells bad and you aren’t quite sure why — don’t panic.

We’re here to help you get to the bottom it and get your unit back up and running the way it’s supposed to.

Before you can get to fixing your smelly AC, you’re going to have to ask yourself one critical question, “what does it smell like?”

Does It Smell Like Something’s Burning?

It’s a bit like the saying goes, where there’s smoke — something’s burning.

If you smell smoke coming from your AC, that means something is burning, and you need to shut down your HVAC system ASAP and call in a professional.

Does It Smell Like Mold or Mildew?

Have your allergies been acting up a lot lately, and you can’t figure out why? A build-up of moisture in and around your AC system can lead to a lot of mold and mildew, which can spell big trouble for your health.

If the air coming out of your vents smells a bit moldy, you should start by changing out your filters. Then, call in an HVAC specialist who knows how to handle mold to clean everything up and prevent future issues.

Does It Smell Like Fireworks?

A gun powder or firework smell generally means something in your system, like the circuit board or fan motor, shorted out.

Unfortunately, it won’t take long for you to feel the effects of this issue as your unit will likely stop cooling or circulating air following a short.

So, if you smell fireworks where there are no fireworks, you should probably call a professional HVAC repair service.

Does It Smell Like Rotten Eggs?

A sulfur or rotten egg smell usually only means one thing: you’ve got a gas leak.

If you smell rotten eggs coming from your AC vents, you should immediately extinguish any flames and open as many doors and windows as you can. Then, you should evacuate the building and contact your gas company.

Does It Smell Like Death?

If the air coming out of your vents smells like something died, then, odds are, that’s what happened.

Small critters, like rodents and even some birds, can get into your system and get themselves stuck without you ever knowing about it. That is until they start to decompose, of course.

You may be able to locate and remove the dead animal yourself. That said, to get rid of the smell, you’re going to have to bring in a professional to clean your ducts.

Can’t Figure Out Why Your AC Smells Bad?
