How to Reset Your Air Conditioning System

Sometimes heating and cooling systems can lock out due to a fault. This may be caused by a storm, power surge, or an intermittent error that has since cleared.

Important: Before attempting a reset, please take note of any fault codes or unusual symptoms. These details will help if a service call is later required.

Meter Box with circuit breakers

Step-by-Step Reset Instructions

• Locate Your Meter Box – The electrical meter box is usually located near the front or side of your house. This is where your electricity provider takes meter readings.

• Open the Meter Box – Inside, you’ll find a series of circuit breakers or fuses.

• Find the Air Conditioning Circuit Breaker 
  • It’s commonly labelled ‘A/C’ or ‘Air Conditioning’.
  • If you have more than one system, you may see ‘A/C 1’, ‘A/C 2’, etc.
  • Some boards use numbers and include a sheet identifying each circuit.

• Check the Circuit Breaker Position
  • If the breaker is OFF, try turning it back ON.
  • If it trips again immediately, do not continue — contact our service team.
  • If it is already ON, switch it OFF and leave it off for 20–30 minutes.

• Turn It Back On – After waiting, switch the breaker back ON and allow the system 10–20 minutes to complete its startup cycle.

• Check System Operation – Once the system has restarted, check if it’s running normally. Be patient — in extreme temperatures, it may take longer to notice heating or cooling effects.
