It’s the end of furnace season in Canada (hopefully!) and it will only take a 1/2 hour to complete the season in a clean way, and get ready for next winter.
This is a two part challenge that won’t take very long!
1. Change your furnace filter
2. Vacuum out your large air intake vents
Your home’s air will be much more fresh and clean, and ready for the furnace to come on, next time.
