Heating and ventilation

  • Health Canada recommends a professional inspection of fuel-burning appliances at least once a year, or as the manufacturer instructs.

  • Natural Resources Canada recommends changing or cleaning filters every three months or as they become loaded.

  • Natural Resources Canada advises keeping return-air grilles and warm-air vents clean and free of obstructions.

    DIY
  • Health Canada recommends having a wood-burning fireplace chimney cleaned every year.

  • Gas appliances should only be serviced by a licensed gas technician.

  • Natural Resources Canada recommends annual maintenance by a qualified contractor.

  • CMHC suggests cleaning or replacing HRV filters about every two months and cleaning the core as the manufacturer recommends.

Water and plumbing

  • Water left in the line can freeze and burst the pipe inside the wall.

  • Water trapped in lines, valves and heads can freeze and crack them.

  • Pipes in cold spaces are the most likely to freeze.

  • Government of Canada flood guidance says the discharge line should be unobstructed and direct water away from the foundation.

Exterior and roof

  • Government of Canada flood guidance recommends cleaning gutters twice a year. Clogged gutters overflow and can add to ice dams.

  • Small leaks get worse under snow and ice. Roof work belongs to an insured roofer.

  • Sealing cuts drafts and helps keep mice and insects out.

  • Mice look for shelter indoors as temperatures drop.

Safety

  • Health Canada recommends testing smoke alarms every month and replacing any that are more than 10 years old.

  • Health Canada recommends a test of at least 3 months, ideally in the fall or winter. You can use a do-it-yourself kit or a certified professional.

Yard and garden

  • Stakes help plows avoid your lawn, curbs and garden beds.

  • Water left in pumps, filters and lines can freeze and crack them.
