Vehicle air conditioner problems

AC systems can malfunction for a number of reasons. Some of them include:

  • Leaky or clogged condenser
  • Inaccurate refrigerant level
  • Refrigerant contamination
  • Unresponsive pressure switches
  • Damaged compressor
  • Clutch problem
  • Belt is blown
  • Dusty, debris-ridden filters
  • The ac system has leaks
  • Control head malfunctions

It is common for AC quality to be diminished when refrigerant levels are low. Our technicians will offer cost-effective solutions if your AC system has additional problems besides low refrigerant.

It is not recommended to recharge your AC with DIY cans from the store. Add refrigerant incorrectly or unnecessarily and your AC system can be irreparably damaged.

AC units usually warn you when they are failing or struggling.

An AC problem in a vehicle can be detected by the following signs:

  • Vents or hood sounds may be unusual when an ac is malfunctioning.
  • If your vehicle is smelling unpleasant, you may have bacteria building up in your evaporator. It could be more than thrown-out fast food or gym clothes.
  • You may have a problem with your compressor if your air conditioner blows inconsistent temperatures.
