About Hamilton
Hamilton sits at the western end of Lake Ontario. Since the 2001 amalgamation the city also includes Ancaster, Dundas, Flamborough (including Waterdown), Glanbrook and Stoney Creek, so many local businesses list those communities in their service area. The Niagara Escarpment — "the Mountain" — divides the lower city from the upper city.
💲 Typical cost
Published pricing guides suggest HVAC service calls in Ontario commonly cost around $75–$150 an hour, and furnace diagnostic visits around $80–$150, often credited toward the repair. New equipment is quoted by model, capacity and installation work, so compare written quotes for the same equipment. These are planning ranges only — ask for a written quote, and check whether HST is included.
🪪 Gas and refrigerant work
Gas work on furnaces and other gas equipment generally must be done by a TSSA-registered fuels contractor using certified gas technicians; you can check a contractor with TSSA's online contractor search. Refrigerant handling requires an Ozone Depletion Prevention (ODP) certificate, and repairing refrigeration or air-conditioning equipment may also require the applicable trade qualification. Unsolicited door-to-door sales of furnaces and air conditioners are not allowed in Ontario.
🧾 What a quote should include
A quote for new equipment should list the make and model, its heating or cooling capacity and how that size was chosen (a load calculation), any permit, removal of the old equipment, and the manufacturer and labour warranties. Compare quotes for the same scope.

Should I repair or replace my heating or cooling system?
Repair usually makes sense for a newer system with a single fault. Replacement is worth considering if the system is old, needs frequent or major repairs, or no longer keeps your home comfortable. Ask for written quotes for both, including the model, capacity and warranty.
