Everything that keeps a house comfortable.

Heating, cooling, ventilation and hot water — diagnosed with instruments, quoted before we start, and warrantied when we are done.

All services
Know your system

The six parts that fail — and what it costs when they do.

Tap any point on the diagram. This is genuinely what our technicians check, in this order, on every call.

Instant estimate

Four questions. A real number.

No email gate, no "a specialist will call you." These are our actual GTA pricing bands, applied to what you tell us.

Why Sam's

We measure. Most companies estimate.

There is a reason so many GTA homes have a hot main floor and a freezing bedroom over the garage: the equipment was sized by rule of thumb and commissioned by eye. We do the arithmetic, take the readings, and hand you the numbers.

  • Heat-loss calculations, not guessesEvery replacement gets a CSA F280 load calculation. Oversized equipment short-cycles, runs loud and dies young.
  • Commissioning that is actually doneGas pressure set, temperature rise verified, static pressure recorded, combustion analysed. It is the step most installers skip.
  • Documented readings, emailedYou get the numbers and the photos after every visit — so next year you can compare, and so nobody can invent a problem later.
  • We will talk you out of thingsIf a repair beats a replacement, or a smaller unit beats a bigger one, we say so. It costs us margin and earns us the next fifteen years.

How it works

From phone call to warm house.

No mystery windows, no "sometime between 8 and 5."

You call or book online

A person here answers, asks the right questions, and tells you honestly whether you need a truck or a two-minute fix you can do yourself.

We give you a real window

A two-hour arrival window with a text when the technician leaves the previous job. Emergencies get dispatched immediately.

Diagnose, then quote

Full sequence-of-operation check with instruments. You see the readings and the price before anything is touched or ordered.

Fix it, prove it, clean up

Repair completed, system re-tested under load, readings emailed, boots covered and the work area left the way we found it.

Where we work

Eight cities. One local crew.

Hover or tap a city for typical response times. We would rather tell you we cannot make it than book a window we will miss.

Based in Mississauga since 2009

Our shop is on Dundas Street East, which is why Mississauga, Brampton, Oakville and Etobicoke get same-day service as standard. We hold the rest of the GTA to an honest booked-appointment promise instead of pretending otherwise.
