Is Your AC Making Your Home Smelly?

Find out why and how to fix it

Air conditioners are your best friend if you live in Florida, to be living without one this summer would be miserable. Have you ever noticed a strange odor come from your A/C when it is turned on? Well this could be an obvious sign of problems ahead. The air quality of your home is very important and if your home shows any of these symptoms here’s what they could mean:

Exhaust Fumes May Be Leaking In

Even though you air conditioner is not powered by gas, the engine and a few other components of it have fluids in them that can sometimes leak out. If this happens, the smell of exhaust fumes may resonate in your home. To prevent any harm to you or family make sure you have the A/C checked out as soon as possible by an HVAC technician.

Be Honest, Does Your Home Smell Like Feet?

Besides just cooling your home, your A/C is also used as a dehumidifier. In the process of removing heat from your home, moisture is removed. If your air conditioner is too large for your home it will cool your home especially fast leaving no time to remove the moisture from the air. With a large A/C, extremely hot and humid days (every summer day in Florida) can cause mold and mildew to grow on some of your air conditioner’s components and distribute a “dirty sock” type smell around your home.

Your cooling coils could also be dirty. Your air conditioner blows air directly over its cooling coils so if your coils are dirty, or if bacteria or other microorganisms have grown on them, your air can pick up some foul smells from the coils themselves.

Another smelly situation you may be in is when you have a dirty, clogged air conditioner. If stagnant water collects in the system and the condensate drain doesn’t drain it away properly, the feet smell is what you’ll get. Water will build up in the drain pan and create a breeding ground for mold and mildew, which will give off that terrible smell. A thorough cleaning by a professional should be enough to remedy the problem.

Sewage Leaks Make for the Smelliest Problem

Lastly and worst is the possibility of a sewage smells in your home. This odor may be coming from a backed up sewer line or ruptured sewer vent pipe near the duct system. All it takes is a tiny bit of methane gas from the sewage leak to get into the duct work and your entire home will fill up with that sewer smell. Methane gas is very dangerous, so if you start to smell it in your home it would be in your family’s best interest to get ahold of an HVAC technician immediately look into the problem.
