Replacing an old, leaking, or inefficient boiler across Toronto and the GTA. We remove your old unit and install a modern high-efficiency combi or condensing boiler — TSSA-licensed, fully permitted, with honest sizing.
Whether your boiler quit, sprang a leak, or just costs too much to run, we get reliable heat back fast — with the right unit for your home.
We replace aging cast-iron and atmospheric boilers with modern condensing units that vent through PVC and recover heat older boilers waste — lower bills and steadier heat.
Replace a separate boiler and hot-water tank with one wall-mounted combi. Frees up floor space and gives you on-demand hot water alongside your home heating.
We carry popular Navien and Rinnai units in stock and can usually replace a failed boiler within the week — sooner in a no-heat emergency.
Catch these before a mid-winter failure and you can plan the job on your terms.
