Hamilton Heating Services — Furnace, Boiler, Heat Pump Experts
Hamilton heats with more kinds of equipment than any other city we serve, because the housing spans 130 years. Westdale, Durand and Kirkendall still run gas boilers through cast-iron radiators, many on their second or third boiler over the original piping. Crown Point, McQuesten and the North End are forced-air homes where ducts were cut into pre-war brick and a mid-efficiency furnace often vents up a masonry chimney. The Mountain's 1950s wartime streets and 1970s–90s subdivisions are due for their next furnace, while Ancaster, Stoney Creek Mountain and Binbrook new builds increasingly pair a heat pump with a backup furnace from day one.
For radiator homes we replace the boiler, not the radiators. Hot-water heat is even and quiet, cutting ducts into a double-brick Westdale house is destructive, and a condensing boiler sized to the real heat loss — with a proper expansion tank, circulator and low-water cutoff — usually fits where the old unit stood. For forced-air homes we install condensing furnaces at 95% AFUE or better, the federal minimum for new gas furnaces, with a CSA F280 heat-loss calculation, a gas-line capacity check and venting to CSA B149.1. The furnace cost guide shows how those quotes are built.
Heat pumps are the fastest-growing part of our Hamilton work. Cold-climate units from Mitsubishi and Daikin keep producing useful heat well below -20°C, so an Ancaster or Binbrook house can run the heat pump through most of the winter and hand off to gas only on the coldest nights — wind exposure at the Escarpment brow is the main reason we keep the furnace in the system. A 3-ton cold-climate heat pump installs for $9,500–$15,000 and current Ontario programs return up to $7,500; Alectra Utilities adds no rebate of its own. Heating quotes are free, and the Hamilton service area page lists the rest of our city work.

Heating in Hamilton — FAQs
How much does a new furnace cost in Hamilton?
A high-efficiency furnace installs for $4,300–$7,000 in Hamilton, most jobs landing at $4,500–$6,500, with premium modulating lines carrying a $500–$1,500 brand premium. Lower-city homes on a masonry chimney often need a liner for the water heater the furnace leaves behind, and gas-line upsizing where needed adds $400–$1,200 — both shown as quote lines, not surprises. Doing furnace and AC together runs $7,500–$11,500 and saves $1,000–$2,500 over two visits.
Should I replace my heritage Westdale boiler with a forced-air furnace?
Almost never. Radiator heat is even and quiet, and running new ducts through a double-brick Westdale house means opening plaster and losing closet space at a cost that dwarfs a boiler swap. A condensing boiler replaces the old unit on the existing piping. The boiler versus furnace comparison covers the rare case where forced air wins — usually an owner who also wants central air conditioning.
Is a heat pump worth it in Hamilton?
For most Ancaster, Stoney Creek Mountain and Binbrook homes with sound ductwork, yes, as a dual-fuel system: the heat pump cools in summer and heats through most of the winter, and the gas furnace covers the deepest cold and the wind at the brow. Current Ontario programs return up to $7,500 on qualifying units. Lower-city homes with undersized ducts often do better with a ductless cold-climate system. Is a heat pump worth it in our winters gives the honest version.
How long does heating system installation take in Hamilton?
A furnace swap is a working day. A furnace-plus-AC job or a ducted heat pump usually needs a second day for the line set, electrical and commissioning. A boiler replacement in a Westdale radiator home takes longer still, because the system is drained, refilled and purged zone by zone. How long a furnace installation takes breaks down where the hours go.
Are there rebates for Hamilton heating system upgrades?
For heat pumps, yes: the Home Renovation Savings Program (Enbridge and Save on Energy) returns up to $7,500 on qualifying cold-climate heat pumps and $75 on a smart thermostat — the program page carries the eligibility rules. A furnace-only swap doesn't currently qualify, the Canada Greener Homes Grant is closed to new applicants, and Alectra runs no equipment rebate. We file the paperwork on every qualifying install; the rebates hub tracks changes.
