How often should I clean my car's air con?
My local garage recommends air con cleaning out every two years. Is this necessary?
If he means the ventilation trunking, you can do that yourself. Get the car to temperature, switch the heating to max, select the ventilation you normally use, then get out of the car and stand beside it for 15 minutes while the heat kills off all of the bacteria in the trunking.
