We are based at 5625 Topaz Pl in Churchill Meadows, which puts us a few minutes from Erin Mills, Lisgar and Meadowvale and inside half an hour of almost anywhere in the city. That matters more than it sounds: Mississauga is large and its housing was not built all at once, so what is sitting in the basement changes considerably depending on which part of the city you are in.
Churchill Meadows, Lisgar, Central Erin Mills, Meadowvale and Streetsville’s newer edges went up largely between the late 1980s and the mid 2000s. The original high-efficiency furnaces and air conditioners in those homes are now twenty to thirty years old, which is squarely replacement territory. What we see most often here is a system that still runs but has started needing a repair every season, and an evaporator coil that is the same age as the furnace it sits in. That is the point at which repeated repairs stop making financial sense.
Port Credit, Lorne Park, Mineola, Clarkson and Lakeview are a different problem entirely. A lot of that stock predates 1960, and much of it has been added to, finished or converted since. Additions built off the original trunk are the usual reason one room never gets warm, and mid-efficiency units vented into a masonry chimney still turn up. Those need a careful look at venting before anything is replaced, because swapping to a condensing furnace changes how the whole chimney behaves — particularly where a water heater is sharing it.
These are largely 1960s and 1970s builds with ductwork sized for the equipment of the day. Undersized returns are common, and they quietly limit what any new system can deliver. Where we find that, we say so before quoting a bigger furnace, because a larger unit on a restricted return does not fix the cold room — it just runs harder and wears out sooner.
Whichever part of the city you are in, calls are answered 24 hours a day and our published air conditioning diagnostic is $165 + HST. Installed prices are on the pricing list rather than behind a phone call.

Quite possibly. A furnace installed with a mid-1990s subdivision home is now around thirty years old, which is past the point where most makes are still economical to repair. The evaporator coil in it is usually the same age. If it has needed a repair in each of the last two seasons, it is worth pricing a replacement rather than fixing it again.
Moving from a mid-efficiency furnace to a condensing one changes the venting completely: the new unit vents in PVC through a side wall and needs a condensate drain. If a water heater is sharing that chimney, taking the furnace off it can leave the chimney oversized for the water heater alone, which has to be addressed at the same time. We check that before quoting, not after.
Gas work in Ontario is regulated province-wide by the Technical Standards and Safety Authority, so the same licensing and inspection rules apply in Mississauga as everywhere else in the province. Furnace, boiler, water heater and gas line work is done to those standards and permitted where the municipality requires it.
