CO is invisible and odourless. Test your CO alarms monthly, keep furnace vents clear of snow and debris, and book a yearly furnace inspection so small cracks and leaks are caught early.
Before the first cold snap: replace the filter, test the thermostat, clear space around the furnace, and run the heat for 15 minutes to catch problems while it's still mild outside.
A clogged filter makes your furnace work harder and drives up energy costs. Check it monthly in peak season and replace standard 1-inch filters every 1–3 months.
