Cold air is the only thing you want from your AC. If you’re getting smelly odors instead, then your AC has a problem. Let’s discuss four AC odors and their causes.
1. Fingernail Polish Remover
Fingernail polish remover contains a chemical called acetone. If you smell this odor around or near your AC, there’s possibly a refrigerant leak.
Refrigerant is safe for your AC. However, it’s a toxic chemical, and exposure puts your health at risk. A professional HVAC technician should check your AC if you suspect a refrigerant leak.
2. Damp Soil
The smell of damp soil can signal bacterial growth somewhere in your HVAC system. Some people describe it as a musty odor like sweaty socks.
A problem with moisture building up in the evaporator coil or ductwork is a common cause of this issue. The moisture creates a good environment for spores.
The smell is unpleasant and can aggravate allergies or asthma. It also lowers your indoor air quality.
3. Something Burning
The smell of burning can signal an overheating component or a failing motor. If it’s an electrical issue, then it might smell like burning plastic or rubber.
Electrical issues can lead to serious damage or fire. Turn off the AC if you smell something burning, and get professional help.
4. Fishy Smell
When plastic or electrical insulation overheats, it smells like fish to some people. Things like wiring, circuit boards or other components can get too hot, causing the insulation on them to release a fish-like smell. This odor is not something to ignore because it’s a fire hazard.
Lots of issues can make your AC smell bad. The only way to diagnose the problem is to get professional help. Contact Air Specialty in St. Elmo, AL for AC repair services.
