Post-war bungalows
Many North York bungalows from the 1950s and 60s still have their original duct layout, with supply registers on outside walls and one or two central returns. A few things come up again and again:
- Orphaned water heaters left venting alone into the old chimney after a furnace upgrade. These need a chimney liner or a power-vent water heater.
- Undersized returns that make a new high-efficiency furnace noisy and hot.
- Basements finished decades later without enough heat.
Custom rebuilds
When a bungalow is replaced with a large new house, the HVAC is a different job: often two furnaces or zoning, a high-output water heater or combi boiler, in-floor heat in basements, and bigger gas loads for ranges, fireplaces and BBQs. Gas pipe sizing matters here, and so does getting the gas meter capacity confirmed early.
Condos
For suite heat pumps, fan coils and ductless units, we check building requirements before quoting any replacement.

What our customers say
Questions we get in North York
Can you work on a custom home with two furnaces?
Yes, including zoned systems, combi boilers and radiant floor heat.
Why is my new furnace so loud?
Usually not enough return air or a restrictive filter. A static pressure test tells us quickly.
Do you handle gas lines for kitchen renovations?
Yes. We size the line for all the appliances, install shut-offs and pressure test it.
