    Why does my McQuay Air Conditioner compressor not start right away?
    • W
      whitedavidSep 1, 2025
      If your McQuay Air Conditioner's compressor doesn't start immediately after you turn on the unit, it could be due to a built-in protection against frequent starting. Allow 3 to 4 minutes for the compressor to start automatically.
