Once a year, ideally in early fall before the cold sets in. If you have not had it done yet this year, book it now: November is still better than the first night it fails. Between visits, change the filter every one to three months.
That schedule is the one Air Source Home Comfort recommends. They are the heating and cooling company Good Neighbours recommends in Barrie.
The yearly schedule
- Early fall: furnace service.
- Spring: air conditioner tune-up.
- Every one to three months: a new furnace filter. Homes with pets or heavy use are at the short end of that range.
Why it matters in Barrie
A furnace works hardest in January and February, and that is when a neglected one tends to fail. A yearly service catches worn parts while a repair is still a scheduled visit and not an emergency call.
Signs your furnace needs attention now
- Rooms that do not warm up evenly
- The furnace switching on and off more often than it used to
- New noises or smells at start-up
- A heating bill that climbs without a colder month to explain it

He handled the maintenance work efficiently, then made adjustments to make sure the entire house stayed warm.

If you suspect a gas leak or your carbon monoxide alarm goes off, leave the house first and then call.
