AC Won't Turn On?

If nothing happens when your air conditioner should be running, an HVAC professional can evaluate the system and explain what they find.

What this usually looks like

  • The system does not start when the thermostat calls for cooling
  • The thermostat screen is blank or unresponsive
  • The indoor fan runs but the outdoor unit does not
  • It started after a power interruption

Many causes are possible

A system that will not start can point in a number of directions. We do not recommend opening equipment panels, working near electrical supply, or resetting internal components. A qualified professional can evaluate it safely.

Helpful information to have ready

Sharing a few plain details in your request helps a professional understand the situation before they contact you.

  • Whether the system is cooling at all
  • Whether the problem is constant or comes and goes
  • When you first noticed it
  • Any unusual sounds or odors you have noticed
  • The approximate age of the equipment, if you know it
  • Whether you are looking for repair, replacement, or routine service

What happens next

  1. Submit your service request.
  2. Your information may be shared with independent HVAC professionals who serve your area.
  3. Those professionals may contact you directly.
  4. You decide whether you want to work with any of them.
