Furnace Repair Scarborough
Bungalows, back-splits and basement suites, which is most of Scarborough. We diagnose the distribution as well as the furnace, because in a split-level the two get confused constantly.
The Split-Level Heating Problem
Scarborough was built out in the 1950s through 1970s, and a large share of it is back-splits and side-splits. More than half the “my furnace is broken” calls we take here turn out to be a distribution problem in a house shaped like a staircase.

2-4 Hour Emergency Response
Scarborough sits inside our core area, so emergency furnace calls run a 2-4 hour window, 24/7. The $129 diagnostic does not change rate overnight or on holidays.
City of Toronto Permits
Scarborough has been part of Toronto since 1998, so installations go through the City of Toronto building department. We handle that filing ourselves.
Homes With A Basement Suite
Second suites are more common in Scarborough than in most of the city, and they change the safety picture rather than just the comfort one. If your house has one, this part matters more than the furnace model.
- A basement apartment adds a kitchen, a bathroom fan and often a dryer, all pulling air out of the same space the furnace draws combustion air from. On a naturally drafting furnace or water heater that can pull flue gases back into the house.
- We check combustion air provision and run a spillage test at the draft hood, not just a temperature reading. That test is the difference between a house that is heating and a house that is safe.
- Duct work into a finished basement suite is frequently improvised, with supplies added and no matching returns. That starves the rest of the house and pressurises the suite.
- If you rent the lower unit, heat is your obligation under Ontario's Residential Tenancies Act. We invoice with the technician's findings and readings itemised so you have a record.

Furnace Repair Scarborough - FAQs
How quickly can you reach a furnace call in Scarborough?
Scarborough is inside our core service area, so emergency response is typically 2-4 hours, 24/7. The diagnostic is a flat $129 at any hour and is waived if you go ahead with the repair, with no residential overtime surcharge on evenings, weekends or holidays.
My Scarborough back-split has hot and cold levels. Is the furnace failing?
Usually not. Split-levels put three or four half-storeys around a single furnace and one thermostat, and the returns are almost always concentrated on the main floor. The lowest level has no path to send its air back, so it stays cold no matter how hard the blower runs. We measure duct static pressure and airflow per level before suggesting anything, because a new furnace does not fix a distribution problem.
Would a bigger furnace fix the uneven heating?
No, and it commonly makes things worse. A larger furnace satisfies the thermostat faster, so it runs in shorter bursts and moves less total air through the house across the day. The rooms that were already starved get less. Balancing, added return air, a variable-speed blower or proper zoning are the things that actually change the outcome.
I have a basement apartment. Does that affect the furnace?
It affects the safety check significantly. A second suite adds exhaust fans, a range hood and often a dryer, all competing for the same air the furnace and water heater need for combustion. On a naturally drafting appliance that can cause flue gases to spill back into the house. We run a spillage test at the draft hood and verify combustion air provision as part of the visit.
Do I need a permit for furnace work in Scarborough?
A straight furnace replacement does not. Scarborough has been part of the City of Toronto since the 1998 amalgamation, and Toronto lists replacing a furnace or boiler in a house among the projects that do not need a building permit, while installing or modifying a heating system does. Gas work is governed by TSSA province-wide and our technicians hold G1/G2 tickets.
Do you cover the east end of Scarborough out to Rouge and Highland Creek?
Yes. Agincourt, Wexford, Bendale, Woburn, Guildwood, Birchcliff, Cliffside, West Hill, Malvern, Highland Creek, Rouge, Kennedy Park, Scarborough Village, Dorset Park, Ionview and Centennial are all covered.
Which furnace brands do you repair in Scarborough?
Lennox, Carrier, Goodman, Trane, York, Bryant, Rheem, Napoleon and Daikin among others. We are an authorized Lennox dealer with genuine parts and warranty access, and we service every other major brand.
Is it worth repairing a furnace in a 1960s Scarborough bungalow?
Often yes, because the ductwork in a simple bungalow is usually sound and a repair buys real years. Our rule of thumb is that under fifteen years old with a repair below half of replacement cost, repair wins. Above that, get replacement priced alongside it, and ask about a heat pump while you are at it.

Tell us whether the house is a bungalow or a split, and whether there is a basement suite. Both change what we look at first.
