There are few things as concerning and potentially confusing for Plano, Texas residents as unusual smells coming from your air conditioning unit. When everything is working normally, your AC goes largely unnoticed. When something is wrong, though, it can cause a lot of worry as to exactly what the problem might be. If your air conditioning unit ever starts to give off any of these smells, it may be time to contact a professional.

Rotten Eggs

Assuming you’ve already checked the usual suspect locations, such as the fridge and garbage can, the smell of rotten eggs in your home could quite possibly be coming through your vents. If that’s the case, you’ve got a serious problem on your hands. Natural gas, while odorless on its own, typically has a scent added to it by utility companies to alert you in the case of a leak.

If you smell rotten eggs in your home and you can’t pinpoint the source, you should open all of your windows, get everybody out of the house, and call your local gas company immediately.

Musty Smells

If you’re switching your unit from cooling to heating for the first time in a while, you’re likely to experience a musty smell for the first day or so due to dust and residue buildup. While this is normal, if the smell doesn’t dissipate relatively quickly, you may want to check your air filter. If that doesn’t do the trick, it’s probably time to call a professional to have your unit checked out because it could indicate a larger problem.

Sewage Odors

Everybody knows what this smells like. If a tub, shower, or sink isn’t used often, the trap may have dried out. Run some water down the drain and see if that takes care of it. If not, and you’ve already checked and cleaned suspect areas in your bathroom, sewage smells in your home can be potentially dangerous. This may indicate that a sewage line has broken near your ventilation ducts and can be a serious health concern.

Never assume an odd smell in your home is harmless. If you suspect a smell is coming through your vents, call a professional like Samm’s Heating and Air Conditioning at (214) 251-4438 for help right away.
