Air Conditioning Repair Services

One of the more common AC unit malfunctions is a coolant leak. If your air conditioner is leaking refrigerant, you should contact Mainstream right away. Refrigerant is expensive, and the longer the leak goes untreated, the greater the expense will become. In some cases, a nitrogen test may be needed to determine where the leak is coming from. Your air conditioner may also trip your circuit breaker on occasion. Some of the potential causes for this include:


  • A clogged or damaged air filter

  • Dirty central AC coil

  • A shorted motor

  • A faulty compressor

  • Rodent damage


Our flexible cooling services include AC repair. Our experience in repairing and maintaining both ductless AC and Central AC systems means you can rest easy calling on us!
