Sheet 04General notes
Twenty years of Oakville mechanical rooms
Sean Whitfield spent nine years on new-build HVAC before opening Bronte Mechanical on Speers Road in 2006. There are nine of us: five installers, three service techs and Dana in the office who actually returns calls. We do a heat loss and heat gain calculation on every replacement, because the fastest way to a noisy, short-cycling, expensive house is a contractor who sold you the same size that was there before. We install what the numbers say, we commission it with gauges on, and we leave you the report.

What customers filed back
- Rep. 01
Three companies quoted our furnace and heat pump. Bronte was the only one who measured anything. Sean's report showed our old furnace was two sizes too big, which explained twenty years of the upstairs being freezing. New system is smaller, quieter and our gas bill dropped by a third.
- Rep. 02
No heat, -18 outside, two kids in the house. Called at 6:40am and a tech was in the driveway before 9. Ignitor and a cracked pressure switch hose. He had both on the van.
- Rep. 03
They handled the entire Home Renovation Savings rebate application. We'd have given up on the paperwork. Install crew put down floor protection from the front door all the way to the mechanical room.
- Rep. 04
On the maintenance plan for six years. Same tech most visits, actual written readings each time, and when the AC finally died they credited part of the plan against the replacement.
- Rep. 05
Excellent work on a ductless system for our addition. Scheduling slipped twice in the July heat wave, which I understand, though I'd have liked to hear it from them first rather than having to phone.

Sheet 09Queries
Answered before you ask
A cold-climate unit still produces heat at -25°C, which covers all but a handful of hours a year here. We set them up as hybrids: the heat pump runs down to your changeover point and the furnace takes over below it, so you're never cold and never burning gas you didn't need to.
Most Oakville homeowners qualify for the Home Renovation Savings Program on a heat pump, and there are Enbridge incentives for high-efficiency equipment. We tell you the real post-rebate number in the quote and we file the paperwork.
Because oversized equipment short-cycles: it blasts, shuts off, never dehumidifies, and wears out early. A CSA F280 calculation takes us about an hour and it's the difference between a system that's comfortable and one that's merely warm.
Fifteen to twenty years in a typical Oakville home. Past fifteen with a major failure, we'll usually show you the repair cost against the replacement cost and let you make the call — plenty of our customers repair and get another three winters.
Yes, any brand. Our maintenance plans are open to anyone in the service area regardless of who put the system in.
Yes, on installs over $3,000 — terms up to ten years through our lender. We'll show you the monthly figure next to the rebate figure so you can see the whole picture.
Not on the list?
Call and ask. We'd rather answer it on the phone than have you guess.
