How To Tell If Your Lennox System Needs a Capacitor Replacement

Capacitors are essential in starting and running the motors in your Lennox AC. When they fail, your system may not cool or even power on.

Here’s what to look for:

• Clicking sounds but no airflow – A capacitor may be failing if the unit tries to start but never activates.
• Warm air blowing from vents – Without full motor power, the AC may run without cooling.
• Sudden power shutoffs – Faulty capacitors may cause the unit to shut off abruptly or fail to complete cycles.
• Burning smell near the unit – Overheating or shorting components often indicate a failing electrical part like a capacitor.
• Swollen or leaking capacitor – On inspection, the component may appear bulged or show signs of damage.

If you suspect capacitor failure, Lennox AC repair Delray Beach services can safely test and replace it, restoring full function to your system.
