Optimize Your Air Conditioning System

Switching your thermostat from “heat” to “cool” is usually a sign that summer is fast approaching and it is time to start thinking about your central air conditioning system.

While a yearly check-up is best left to a qualified contractor, there are some things homeowners can do to avoid an ill–timed malfunction of their central air conditioning system:


  • Clean or replace the furnace filter. The air conditioner needs the furnace to circulate the air and a dirty filter circulates dust and other particles throughout the house, cutting down on a furnace’s efficiency.
  • The thermostat should be set below the room temperature and not set for cooling below 20 degrees Celsius which can cause a multitude of problems with your air–conditioner, including freezing up. Ideally, set the thermostat to 25.5°C when at home; 29°C when away.
  • Turn the humidifier off during the summer cooling season. Leaving the humidifier on will only increase the cooling load and force the air conditioner to work harder.
  • Close your drapes or shades on sunny days and ensure all windows in the house are closed.
  • Close off vents in any unused rooms.
  • Use ceiling fans to circulate the air.

Optimizing your air conditioner can lead to energy savings and efficiency and will keep your machine running smoothly all season long.
