Thermostat cycles heating or cooling on and off too frequently (short cycling)

Safety first: No high-voltage work is required.

Steps to reduce short cycling:

• 1. Adjust cycle rate: In the thermostat installer or advanced settings, reduce the cycle rate (CPH) for heating and cooling to a lower value recommended for your Goodman system.
• 2. Increase differential: Increase the temperature differential (swing) so the system runs longer per cycle and cycles less often.
• 3. Improve location: Relocate the thermostat away from drafts, exterior doors, or supply vents that cause rapid temperature swings.
• 4. Check equipment sizing: If short cycling persists, have a professional evaluate whether the Goodman furnace or AC is oversized for the home.
