Unpleasant Smell
If you turn your AC on and an unpleasant smell comes out, it’s possible you have mold growing inside the unit. Mold can be harmful to our respiratory system. There’s also the possibility you have a dirty or old cabin filter. Besides causing respiratory problems for you and your passengers, mold can cause greater harm to the unit. So if you can smell a funky odor every time you turn on the AC, you should definitely get it checked out.
Water Leak
Water is supposed to drain out of the car. If you notice water stains inside the cabin, this might mean the drain under your car is either damaged or blocked. If you notice drained water inside your car, this is a very strong sign to get it repaired before it gets worse.
Restricted Airflow and Higher Temperature
So imagine you turn on the air conditioning, and nothing happens. Maybe you get hot air or just air, in some cases, airflow is quite diminished. This could mean several things. Your ac system has mold that has gathered and it affects the evaporator. Could be that you’re low on refrigerant. Or that your cabin filter is blocked with debris. Whatever the problem may be, you can count on a professional to properly diagnose the problem and provide you with an efficient solution.
Strange Noises
Another popular tell-tale sign to AC issues is hearing strange noises. Good performing AC systems shouldn’t be noisy. Rattling or grinding sounds could mean that your compressor is damaged. Maybe you need a piece to be replaced or you have debris blocking the fan. Address this as soon as you can to avoid costlier damage.
