10 tips to tune up

FaLl MainTenance checklist
  • 1

  • Book a check-up
  • Schedule servicing every fall to keep your heating system running safely and efficiently.

  • 2

  • Inspect your detectors
  • All systems that burn fuel give off gases, so put a fresh battery in your carbon monoxide detector.

  • 3

  • Clear the clutter
  • Keep the area around your furnace clear and keep flammable items well away.

  • 4

  • Change or clean furnace filters
  • Do this to improve air quality and airflow. Refer to your owner’s manual to see how often you should do this.

  • 5

  • Wrap your tank
  • Add an electric water heater blanket to insulate and reduce energy loss by up to 40 per cent.

  • 6

  • Set to save
  • Set your thermostat to 21°C when you are at home. Lower it when you are sleeping (18°C) or away from home (16°C).

  • 7

  • Blow hot air
  • Set your ceiling fan to spin clockwise to circulate the hot air downwards.

  • 8

  • Seal the leaks
  • Caulk, seal or weatherstrip drafts around doors and windows to reduce heating costs up to 30 per cent.

  • 9

  • The deal with ducts
  • About 20 per cent of your airflow is lost to leaky or disconnected ducts. Seal holes and cracks with mastic sealant or foil tape (avoid “duct" tape as it does not last long).

  • 10

  • Control humidity
  • Keep humidity levels at 30 per cent to 40 per cent to keep your home feeling warmer and more comfortable.
