- A lack of refrigerant in a vehicle is the most common problem with automobile air-conditioning systems. Leaks are often the cause for these low levels. Before it can be recharged, the system must first be checked for leaks which could occur due to a damaged hose or compressor.
- Air and moisture entering a vehicle's AC system might cause ice to accumulate and cause blockage problems. A vacuum pump should be used to remove this moisture and air. A one-percent rise in the amount of air in the system will cause an AC's cooling abilities to decline.
- Noise problems coming from your compressor indicate that replacement might be imminent. Using the wrong type of lubricant on the compressor. might also cause noise problems.
