Furnace Tune-Up · Caledon, OntarioFurnace Tune-Up & Maintenance in Caledon
Furnace tune-up and maintenance in Caledon costs $120–$250 as a standalone visit and takes 45–90 minutes: a licensed technician measures combustion, gas pressure, flame signal and temperature rise, cleans what needs cleaning, and writes the readings on the invoice. Book it for September or early October. Caledon is our longest drive from the Burlington shop, so a fall visit you schedule is far easier to get than a January no-heat call.
Annual furnace maintenance for Caledon's natural gas, propane and electric systems
The fuel decides what a Caledon tune-up has to check. Bolton's subdivisions and the village centres burn Enbridge natural gas, and those furnaces run at a manifold pressure of about 3.5 inches of water column. A propane furnace on a rural concession runs near 10 inches through smaller burner orifices, so the technician confirms the conversion kit and its label are in place and sets the pressure with a manometer instead of judging the flame by eye. A furnace set up for the wrong fuel burns badly and can make carbon monoxide, and a combustion analyzer in the flue is how that gets caught.
Large homes change the airflow side of the visit. Estate lots in rural Caledon often have long duct runs and sometimes two furnaces, and a furnace pushing against restrictive ductwork runs hot, trips its high-limit switch and shortens the life of its heat exchanger. We measure static pressure and temperature rise against the range on the rating plate, which tells you whether the problem is the furnace, the filter or the ducts. Each furnace gets its own set of readings.
Three small items cause most mid-winter shutdowns on condensing furnaces, and a tune-up deals with all of them. The condensate trap fills with sludge and holds the pressure switch open, the flame sensor coats over and drops the burners after a few seconds, and the plastic intake and exhaust pipes on an exposed wall drift in with snow. On an open rural lot we look at where those pipes end relative to where the snow piles up, and tell you if they need raising. Well water often carries more mineral than treated municipal water, so the humidifier pad is checked every fall; a scaled pad passes almost no moisture.
Electric furnaces need maintenance too, of a different kind: no combustion test, but the element banks are checked for amp draw, the sequencers for staging and the high-current connections for heat damage. If yours is already misbehaving, see electric furnace repair in Caledon. The general checklist is on the furnace tune-up service page, the spring counterpart is an AC tune-up in Caledon, and the rest of our local work is on the Caledon service area page. Book a fall visit before the first cold week fills the board.

Furnace Tune-Up in Caledon — FAQs
What does furnace maintenance cost in Caledon?
A standalone furnace tune-up is $120–$250. Booking the fall furnace visit and the spring AC visit one at a time comes to $240–$500, and a maintenance plan covering both runs $150–$350 a year with priority scheduling. Anything the technician finds is quoted separately in writing; a common small fix such as a flame sensor or a blocked condensate drain is typically $150–$450. You are never obliged to approve a repair on the day.
When should I book a furnace tune-up in Caledon?
September to mid-October. Caledon sits higher and farther from Lake Ontario than Burlington or Oakville, so hard frosts tend to arrive earlier and the furnace starts its season sooner. The drive from our shop is the longest in our service area, which makes a planned visit much easier to schedule than an urgent one. Booking early gets you a day that suits you, not whatever is left in November.
Does a propane furnace need different maintenance from a natural gas one?
The checklist is the same, but the numbers are not. Propane burns at a higher manifold pressure through smaller orifices, so we verify the pressure, the conversion kit and the flame pattern, and we leak-test the piping and connections at the furnace. Propane is heavier than air, so a leak pools low in a basement instead of dispersing. That is one more reason the leak check is not skipped.
My house has two furnaces. Is that two tune-ups?
Yes. Each furnace is its own appliance with its own burners, heat exchanger, drain and safety controls, so each gets the full set of measurements, and we give you a written price for the pair before the visit. Doing them together is also the chance to compare readings: when one furnace runs a much higher temperature rise than the other, the cause is usually ductwork or a filter, not the furnace.
Can you service an oil furnace on a rural Caledon property?
Oil burners are serviced under a TSSA oil burner technician licence, which is separate from a gas licence. Tell us what you have when you call and we will say plainly whether the annual service is ours to do or your oil supplier's. What we do quote is the move off oil to propane, a heat pump or a hybrid of the two; heating a rural Caledon home compares those options.
