While the AC is primarily made to keep you comfortable by cooling your immediate environment, the effort will be defeated when it smells bad while doing. An unpleasant smell from an AC unit, as it runs, is not something you should ignore as it has health implications most times. Also, those offensive smells normally indicate that something is wrong with your system and that you need to take action. Here are possible reasons why your AC smells when it runs:
Must, Mildew and Mold Growth
This is one of the commonest causes of fouls smelling AC systems. It results from excess humidity or moisture in the HVAC system that can be prevented through proper AC service.
Dirty Sock Syndrome
The smell of stinking socks or feet is normally associated with a dirty or clogged air conditioner. This can be very discomforting and you will need professional cleaning to correct it.
Accumulated Cigarette Smoke
This is an issue in buildings where indoor smoking is allowed. When there is an accumulation of cigarette smoke in the air filter of your HVAC system, the air coming out of the vents will have a stale cigarette smell. Changing the filter and professional cleaning will be required.
Overheating Issue or Wiring Problem
When there is an incidence of overheating motor, a wiring issue, or other mechanical problem, your AC will give out a burning smell. It can also smell like gun powder when it is short from the circuit board. Shut the AC off if you notice this smell and call in the professionals.
Fluid Leaks
Fluid leaks from the engine of your AC and other parts can often result to exhaust fume odor. When you notice this smell, switch it off and call the professionals for AC repair.
Dead Animal in the Air Duct
If your AC gives off the smell of rotten eggs or flesh, it can be an indication that there is a dead animal in the air duct. Rodents and birds that take shelter in the ductwork may die and start decomposing, causing the air from your AC unit to smell bad.
