AC not working right?

Check these items First

AC won’t turn on

If your AC won’t turn on there’s a couple of things you can do to troubleshoot the problem. First ensure your unit is getting power. Check the breaker at your electrical panel, the power disconnect outside your AC condenser, and the disconnect switch on your furnace. Lastly, make sure your thermostat is calling for cooling and properly connected to your thermostat wiring. If that doesn’t fix the problem, make sure any covers are properly secured on the AC condenser and furnace incase a safety switch is preventing the unit from working.

Turns on but doesn’t cool

If your AC condenser is turning on when the thermostat calls for cooling but you aren’t getting cold air at your air registers, it’s likely caused by a couple of issues.

  • Reduced airflow from clogged air filter
  • Blocked vents or return
  • Not enough refrigerant

Try replacing your filter, removing any possible blockage from the vents on your condenser, furnace, and all registers in your home.

The day after Christmas, We got all of our kids back from their other parents' houses and getting set for them to see what Santa did at home and our heat is out. We needed a repair NOW. All of the part suppliers were closed, but Brett was able to talk to other people in his network and get the part and took care of it in one visit. To me, when someone has friends in the business willing to help them help me, that's the sign of someone with a great reputation. He was super friendly, professional, and got our Christmas back on track in no time. Thank you so much, Brett!
