Why Does My AC System Make My House Smell Bad?

As the temperature rises, you seek that blast of refreshing air in your home in Lincoln, CA. However, that cool air may come with an unpleasant surprise — a foul odor from your air conditioning system. Let’s explore what these common AC system odors are and what they mean.

Dirty Sock Smell

Growth of bacteria typically on the evaporator coil or drip pan can cause the dirty sock smell. The high humidity, accompanied by the dark, damp environment inside the coil and pan, is an ideal breeding ground for microorganisms.

Electrical Smell

Like any other appliance, your air conditioner can overheat. This odor is mostly due to electrical wiring issues, overheating components or improper functioning of motors. You must call a professional right away if you smell something burning since it could result in equipment failure or maybe even a fire hazard.

Chemical Odor

Many cleaning products, household chemicals and paints contain volatile organic compounds (VOCs), which may have accumulated in your air conditioner. You need to resolve this problem quickly because it indicates poor indoor air quality. If left unaddressed, prolonged exposure to VOCs can lead to serious health risks.

Musty Odor

If it’s been a while since you cleaned your air conditioner or changed its air filter, it might start giving off that distinct musty smell. You should check and clean ductwork and vents, too, since they can cause the AC system to emit bad smells. A good fix for the problem is to schedule routine maintenance and cleanings to prevent musty odors as well as respiratory issues.

Let our professionals help you tackle the mysterious odors coming from your air conditioning system in Lincoln, CA. Take action today and contact Jaguar Heating & Air to identify the root causes of the smells and repair any issues.
