Our AC Specialists Handle All Types of Commercial AC Repairs

The following common issues are maintained by our AC repair and service technicians:

  • An AC that won’t turn on
  • Excessive noise or vibration during startup or AC operation
  • The fan doesn’t operate but the unit still hums
  • The fan runs, but the compressor doesn’t work
  • Warm air is blown by the AC unit
  • Water collecting around the air conditioner

We can troubleshoot even the most stubborn commercial AC problems:

  1. No power – defective wiring or faltered breakers can easily reduce power to your AC unit. An overheated system can also shut itself off. Our AC repair experts can detect causes of these issues and prevent them from reoccurring.
  2. Refrigerant leak – a refrigerant leak is revealed by a hissing sound, which is not only harmful for the environment, but for the overall efficiency of your entire system. It won’t be a problem for our technician to repair the leak and recharge your AC system.
  3. Defective fan motor – an AC fan keeps air circulating throughout your business area. If the air circulation is inconsistent, repair or replacement may be necessary to address this issue.
  4. A faulty compressor – if the air exiting your AC vents feels warm, it usually indicates a problem with the AC compressor. This component is expensive, that’s why it would be best to discuss your repair/replacement options with one of our professional technicians.
  5. Frozen evaporator coil – warm air exiting vents can also be a sign of a frozen evaporator coil, which could be the result of low refrigerant levels, poor circulation, incessant operation, or other causes.
  6. Clogged condensate drain – insects, dirt and debris can create a clog in the condensate drain over time. This results in leaks and water loss. Our technician can accurately flush your system and prevent the occurrence of the future clogs.
