Air Conditioner Smells Like a Car’s ExhaustDoes the smell coming from your AC remind you of a car’s exhaust fumes? Your AC unit likely has a refrigerant line leak.

Your refrigerant line may leak hazardous chemicals that are bad for the human body and the environment. To prevent damage, quit searching “How to remove bad smell from split AC?” and call an expert immediately to investigate the issue. You can ventilate your home to eliminate the smell while waiting for HVAC repairs.
AC Smells Like Something Is on FireA faint whiff of burning that occurs when you first turn on your HVAC system is usually nothing serious. If it doesn’t dissipate by itself, and your AC smells like a more pungent burnt or gunpowder odor, you might be dealing with a short circuit, overheating motor, or loose sparking wiring. If you’ve just turned on your AC and it’s emitting a faint burning smell, wait several minutes to see whether it dies down. For more pungent burning smells, shut off your AC immediately and contact an HVAC company for air conditioning repairs.

- Mold or mildew in your air ducts and vents
- Clogged filters
- Leaking air ducts
- Dirty evaporator coils
