Service and Maintenanceyour A/C equipment

Maintaining your Air Conditioning (A/C) system is the best way to ensure it keeps you cool during the humid Ontario summers while avoiding expensive energy bills and sudden breakdowns.

  • Check Refrigerant Levels: If the "freon" levels are low, it means there is a leak. A professional must find the leak and recharge the system.
  • Test the Capacitor: This component starts the motor. If it’s weak, the A/C won't turn on during a hot day. Replacing a failing capacitor early prevents a total shutdown.
  • Inspect Electrical Connections: Tightening connections prevents wire damage and potential fire hazards.
