These smells are usually due to dirt, dust and debris buildup in the under-hood air intake vent, trapping water and moisture on the AC evaporator and in the evaporator case. All kinds of nasty gunk (germs, mold, mildew) can fester and grow in that wet, trapped debris.
Why does my car stink when I turn on the AC?
Your A/C Smells Like Mildew or Mold As your vehicle ages, bacteria can grow in the system where moisture typically collects — particularly on the A/C’s evaporator. When this happens, a pungent, mildew-like smell can get blasted into your cabin through your A/C vents.
Why does my AC stink?
In short, a musty smell indicates bacterial growth build-up, which forms on the drain, evaporator coil, or in the drip pan or drain line of your AC. Your evaporator coil is a dark and humid location, so all sorts of mold and mildew can grow, which causes that unpleasant, musty smell. Check if your AC drain pan is full.
How do I get the musty smell out of my AC vents?
How to Get Rid of a Musty or Moldy Odor Check for Mold. Take a look at your condenser coils, as well as the drip pan. Clean your Evaporator Coils. You can clean your evaporator coils to remove excess dust. Use Soap or Detergent. If you find mold in your ductwork, use soap or a detergent solution to clean your ducts.
Why does my car AC smell like rotten eggs?
Rotten Egg Smell Coming from Car Vents A rotten egg smell in your car often indicates a malfunctioning part in the fuel system. If the catalytic converter, fuel filters, or fuel pressure sensors are worn out or damaged, a sulfur gas can leak out and make its way into your car’s cabin.
What does AC mold smell like?

If you have never encountered mold before, you may not be sure what it even smells like. Some describe mold as having an earthy or musty smell.
What does car refrigerant smell like?
Freon usually travels through closed copper coils in an AC unit, but these coils can crack and result in an AC coolant leak. A freon leak will produce a smell between sweet and chloroform. If you suspect a freon leak, talk to a specialist who can use a freon leak detector to help address the issue.
What does AC coolant smell like?
Most refrigerants are described as having a sweet odor, or possibly smelling like chloroform. If you suspect anything, you should call in the experts immediately. Along with damaging the environment, breathing in refrigerants also presents a health risk.

Is R134a toxic?

Chemical hazards R134a vapours decompose when exposed to high temperatures with the formation of toxic and irritating compounds such as hydrofluoric acid, carbon monoxide and carbonyl fluoride.
Is car refrigerant toxic?
Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. Inhaling refrigerant fumes on purpose to “get high” can be very dangerous.
Are air conditioners toxic?
Refrigerants, such as those found in HVAC units and other cooling appliances, cut off oxygen supply. When inhaled in large amounts, this can lead to severe consequences, including death. Symptoms of Freon poisoning include headache, frostbite, dizziness, vomiting, loss of consciousness, seizure and even coma.
How much does it cost to fix an AC leak in a car?
If leaks are detected, it typically costs $150-$800 for minor repairs to a vehicle’s air conditioning system and then recharging it. This generally includes replacing a few parts like hoses, sensors, or either the compressor or condenser.
