5 Reasons Why Your Air Conditioner Smells Bad

5 Reasons Why Your Air Conditioner Smells Bad

Have you been wondering where that horrible odor is coming from? Check your HVAC system. Often, a smelly air conditioner indicates underlying problems, which can quickly get expensive if not treated.

Why Does Your Air Conditioner Stink?

Now, a bad odor does not immediately mean a huge repair bill. Foul smells in your air conditioner can be caused by several things.

1. Overheating

An overheated system often causes a “burning” smell and can even cause strange noises. Electrical problems need to be investigated by a professional immediately upon discovery.

2. Mold and Mildew

Mold and mildew in the vents or on the evaporator coil smell bad, cause problems, and harm your health.

3. Animal Droppings

Often, roaches, mice, and other small creatures leave droppings in ductwork. When your air conditioner blows, the smell gets pushed through the home.

4. Sewage Backup

If your home smells strongly of sewage, the problem may not be the air conditioner. Rather, a backed up pipe may be located near a vent, resulting in a house-wide odor.

5. Dust Buildup

Sometimes, the smell coming from your vents is merely dust being blown or burnt. You can solve this by cleaning your vents.

How Can You Eliminate the Odor in Your Home?

After you determine the source of the smell, the biggest question is how to get rid of it.

1. Fix mechanical issues.

The first (and most obvious) way to get rid of your air conditioner’s smell is to fix the source of the problem. Whether you need to change the filter or call a professional, do what it takes!

2. Clean.

Scented candles, wallflowers, dusted furniture, and fresh floors can make your home smell much better.

3. Cycle fresh air through your home.

Good indoor air quality helps your house smell and feel better. Improve your air quality by opening some windows and removing dust and allergens from your home. Not only does this make your house more comfortable, but it also improves your overall health.

Keeping an Eye on Your Air Quality

If unpleasant odors are coming from your HVAC system, it could be a sign that your indoor air quality is poor. Simply “covering up” the smell with candles or air fresheners might help in the short-term but it won’t eliminate the issue. Improve your home’s indoor air quality by doing the following.

1. Change your air filters regularly.

Air filters trap dust, dirt, and allergens, cycling pollutants through your home. Use quality filters and change them regularly to protect against unwanted particles.

2. Clean your vents.

Vents tend to accumulate dust and bacteria. Clean them every few months to protect your lungs from harmful allergens.

3. Dust and vacuum your home.

Don’t forget the importance of dusting and vacuuming! If you have carpet, it is a good idea to have them professionally cleaned once or twice a year.

4. Groom pets.

Pet fur can be harmful when ingested and it can interfere with the workings of your HVAC system. Wash and brush your pets to keep hair from accumulating.
