Heating and cooling in Dundas
Dundas HVAC work is different from the rest of Hamilton because so much of the town is Victorian, and ZK Mechanical services all of it — hot-water boilers and cast-iron radiators in the downtown brick homes, forced-air furnaces and central air in the post-war streets toward Cootes Drive, and water heaters everywhere in between. We are an owner-operated, TSSA-licensed contractor working out of Burlington, about 25 minutes away via the 403 and Cootes Drive, and Dundas is part of our regular Hamilton service area. Written pricing comes before the work, a $90–$150 diagnostic comes off the invoice once you approve the repair, and our emergency line answers 24/7 with no after-hours premium.
The downtown grid on either side of King Street West is 1850s–1920s brick, and many of those houses still heat with a boiler and radiators, often on their second or third boiler. When one of them gets a high-efficiency furnace or a side-vented boiler, the old brick chimney is frequently left serving only a gas water heater, and an orphaned water heater on an oversized flue will condense and rot the chimney from the inside — so a stainless chimney liner is part of the job, not an upsell. East and south of downtown, the post-war streets around University Gardens and Pleasant Valley are 1950s–70s bungalows and side-splits with forced air and, by now, an air conditioner or two past its useful life. Radiator heat is ordinary work in this town rather than a curiosity, and boiler repair rides on the same van as furnace work.
Dundas sits on the floor of a valley walled in by the escarpment on three sides, with Spencer Creek running through the middle of town. That geography traps cold air on clear winter nights, keeps the valley humid and still in summer, and leaves many downtown basements damp — which is hard on furnace cabinets, water heater bases and anything else made of sheet steel sitting on a stone-foundation floor. We put equipment on a raised pad where the floor is wet, add a condensate pump when there is no floor drain, and recommend a whole-home dehumidifier or a properly set-up air conditioner for the muggy weeks in July. Enbridge runs the gas main, Alectra Utilities bills the hydro, and permits — including any new venting through a heritage wall — are filed with the City of Hamilton, which took Dundas in at amalgamation in 2001.

Why ZK Mechanical in Dundas
Cast-iron radiator systems in the Victorian downtown are serviced, repaired and replaced by our own TSSA-licensed technicians. We keep the radiators, replace the boiler with a condensing unit where the piping allows, and set the outdoor reset properly so the system stops short-cycling in mild weather.
If your Dundas home is getting a side-vented furnace, the water heater left alone on the old brick chimney needs a properly sized stainless liner or its own power vent. We include that in the written quote up front, because a condensing flue in a 120-year-old chimney is how brick ends up on the basement floor.
Valley basements are wet, so we raise furnaces and water heaters off the slab, use a condensate pump rather than hoping gravity finds a drain, and steer you away from steel-based standing tanks where a tankless unit on the wall would outlive them. A tank swap runs $1,200–$2,500 and a tankless conversion $3,500–$6,500.
Our 24/7 line covers no-heat calls in Dundas with no overtime, weekend or holiday surcharge, and the usual winter faults — igniters, flame sensors, pressure switches, capacitors — sit between $150 and $450. If it turns out to be a bigger part such as a blower motor or control board, we quote it in writing before replacing anything, and you can book the visit here or on the emergency line.
