If you’re not putting a lot of miles on your car, mold and mildew can develop in your car’s air conditioner and heater system. The first time you turn on the A/C you may get an odor. The odor is most likely a buildup of bacteria and debris that’s deep inside the A/C vents. This smell may be harmful and not healthy to breathe, especially if you have respiratory problems.
To avoid any problems with your car’s air conditioner, have your service professional perform an air condition service check, which includes an inspection of the cabin filter and vents. In addition, a performance check should be done on the air conditioner to insure it’s working properly to keep you cool and comfortable all summer long.
