because you have too many dead babies in your air conditioner tank
An air conditioner should not smell like smoke when turned on (or when turned off). I would have to suspect that the electrical insulation is burning.
Take it back to the dealer. The AC drain is Blocked OR the Heater Core is Leaking.
sounds like your A.C. compressor clutch is locking up
it smells sour (bad)
A smell coming from a reverse cycle air conditioner may be a signal that the filter needs to be cleaned. A smell like engine exhaust might be present if the air conditioner motor is in need of repair.
It releases acetic acid(vinegar) as part of the curing process.
Put conditioner in it then wash it out with cold water instead of warm or hot water! it works very good STOP!! using conditioner!!!! My hair is the same why,use apple cider vinegar wash it out good and you will not smell like vinegar trust me!!! And if you don't want to do that go and buy some mane and tail horse shampoo and conditioner and don't put the conditioner on the top of your head this shampoo is awesome i use it myself
It depends; did you wash it?!
Failed compressor
You can tell when vinegar diffuses into a cube as the cube is wet and smells like acetic acid (vinegar smell).
burn it. If it smells lke vinegar, its in the process of hydrolyzing.
Pour white vinegar on the affected area and soak it well. Use paper towels to remove excess vinegar. It will smell strongly like vinegar for a few days, but once the vinegar odour is gone, so should the urine smell. Vinegar neutralizes a variety of unpleasant odours. Do not use red vinegar as this will stain your carpet.
