Tempstar air conditioner outdoor unit runs continuously and rarely shuts off

Safety first: Ensure filters and coils are clean to prevent strain on the system.

Steps:

• 1. Replace filter and clean coils: See earlier entries for cleaning procedures.
• 2. Check thermostat setpoint: Avoid setting more than 20°F below outdoor temperature in extreme heat.
• 3. Verify doors and windows: Ensure the home is closed up and well-sealed.
• 4. If system still cannot reach setpoint: Have a technician evaluate system capacity, refrigerant charge, and thermostat calibration.
