Air conditioning is frequently quoted as one of the best inventions and offers on-the-spot relaxation in a hot climate within a single click of a button. Combined with one of his ten best inventions, cars, you have one of the world’s most profitable combinations of all time. However, if you neglect to check your car’s air conditioning system regularly, you have a recipe for a really bad combination – inconvenience and huge repair costs.
Regular inspections by local tire dealers include leak tests or broken seals that allow refrigerant to leak out of the system. If you run the air conditioner without enough refrigerant, the compressor can get damaged or catch fire, which will cost a lot of money for auto air conditioning repair.

The refrigerant comprises light mineral oil that smoothly greases the moving components of the system during operation. Some air conditioning systems, especially high-end vehicles, actually detect this condition and stop the compressor from running if there is not enough refrigerant in the system.
Air conditioning problems usually arise in two ways:
Insufficient cold air, which can be caused by:
- Low refrigerant load
- Loose belt
- Sliding compressor clutch
- The evaporator is clogged
- The condenser is blocked
There is no such thing as cool air that can be caused by:
- The drive belt is broken
- The fuse blew
- The compressor is damaged or the compressor sliding clutch
- The expansion valve is blocked or damaged
- Receiver dryer or cooling line clogged
- The hose, seal, valve, or compressor is leaking
