Air Conditioner - No Cooling

  • Check the settings on your thermostat. Make sure the temperature control selector is set below the current room temperature, and the system switch is on the COOL or AUTO position. The fan switch should be set to ON for continuous airflow or AUTO if you want the blower to operate only while the air conditioner is operating.
  • Try to get the air conditioner to turn on by lowering the thermostat to its lowest temperature setting.
  • If the air flow out of your registers seems low, check the air filter. An extremely dirty air filter can block air flow.
  • Make sure all registers are open and not obstructed.
  • Check the power disconnect switch by each unit (outdoor and indoor).
  • Check the fuse/breaker at the electrical panel for both the outdoor and indoor unit.
  • If the problem persists, please call us.

Local family owned company. Rudy was professional and knowledgeable when troubleshooting my tricky furnace problem. He didn't have all the parts on the truck with him, but got them and returned the same day with a few other guys and got the job done. Thanks Rudy!

This company really came through for me when my heating stopped working during a November cold spell. They also installed an air conditioning system for me. They are some of the nicest people and run a very professional business.

Meredith G.

Dryer vent installed in timely, efficient manner. Professional engagement, easy appointment process, and punctual. Not sure what these things should cost, but $300 not to have to make a big hole in the side of my house myself felt good to me. Happy to recommend.
