What Do I Do If My HVAC Starts To Smell Bad?

If you find that your HVAC is starting to smell bad, there could be a few things behind it. Here are some common causes and what you should do if it happens to you.

It is important to realize that a different smell means a different problem. Therefore, to diagnose the sort of issue you are experiencing with your air conditioning system, you need to begin by understanding what sort of smell is going on!

Burning Smell

If you can smell something that is burning, the chances are that this is exactly what is happening. This could be a problem with the wiring or it could be that your motor is overheating. If not, it is likely to be some other type of mechanical issue. Either way, this is a serious issue. You need to turn the HVAC system off right away and get in touch with a professional who can determine what is going on.

Sewage Smell

Another common smell that HVAC systems can produce when there is a problem is a sewage smell. Sewer gases can end up backing up into your property if the P-traps are dry. You should try running the water in all of your sinks at least once per month. The purpose of this is so that the P-trap fills and there is a seal created against those dreaded sewage smells.

If dry P-traps are not the issue, you may have a sewer line that is backed up, or the issue could be a sewer vent pipe that has become ruptured. One thing is for sure, though; sewer gases can be dangerous. Therefore, we recommend that you get in touch with an experienced HVAC technician at the earliest possibility.

Rotten Egg Smell

Does your HVAC system smell like rotten eggs? There certainly isn’t anything pleasant about having this sort of smell in your home. However, one thing you should never do is ignore it. This smell tends to be one of the most serious, as it can indicate that you have gas leaking in your home.

Dirty Trash/Rotting Carcass Smell

Does your HVAC system have a smell that is like dirty trash or a rotting carcass? If so, this could indicate that a critter has died in your duct or HVAC system. When this happens, the smell can become so intense that you simply cannot ignore it. The sooner that the decomposition is spotted, the better. Simply turn off your AV system and then get your windows and doors open for some much-needed ventilation. After this, contact a pest management company or a professional HVAC technician at the earliest opportunity for some assistance.
