The furnace check worth doing in October
A ten-minute look that heads off most first-freeze breakdowns.

Most no-heat calls come in the first cold week of the year. A few minutes in October heads off most of them.
Change the filter
A clogged filter is the single most common cause of a furnace shutting itself off.
Run it before you need it
Turn the heat on for an hour on a mild day. A dusty smell is normal. A burning smell or a lot of clicking is not.
Book the tune-up
A yearly tune-up catches cracked igniters and failing flame sensors before they leave you cold.
