“Our old gas furnace quit on a cold night and they had it running again by morning. Fair pricing and no upsell.”

Fast Diagnostics and Lasting Fixes for Ailing Boilers
Many of St. Marys' limestone and Victorian homes still heat with boilers, and St. Marys Heating & Cooling keeps them running safely through every Perth County winter. We repair and install condensing and natural-draft boilers on gas, propane, and oil, feeding radiators and in-floor hydronic loops, and we know the quirks of century systems hidden behind heritage walls.
Why Homeowners Call Us
Is your boiler struggling to keep a century home warm?
From pressure drops and leaks to a full high-efficiency replacement, we service gas, propane, and oil boilers across St. Marys and Perth County.
Fast No-Heat, Leak, and Pressure Repair
When a boiler loses pressure, springs a leak, or leaves a zone cold, we diagnose the real fault, whether it is the circulator, a valve, or the burner, and get heat flowing again without pushing an unnecessary replacement.
High-Efficiency Boiler Installation
When an aging natural-draft boiler is due for replacement, we size and install modern condensing boilers on gas or propane that trim fuel bills and fit the tight mechanical spaces common to century St. Marys homes.
Annual Maintenance and System Flush
A yearly service and hydronic flush keeps a boiler efficient and catches small faults before they fail mid-winter. We service gas, propane, and oil units, plus the radiators and in-floor loops they feed.
FAQ
Boiler Service in St. Marys: Common Questions
How much does boiler service cost in Ontario?
Honestly, it varies. Age, fuel type, and the failing component all move the number. What stays fixed is a written, no-obligation quote before a wrench turns.
How quickly can you fix a boiler with no heat?
It depends what broke. Simple faults are sorted on the same visit, while a cracked section or obsolete control means ordered parts and an honest repair-versus-replace talk.
Should I repair my old boiler or replace it?
Run the numbers against a winter of fuel bills. If the repair costs a fraction of replacement, fix it. If efficiency is already gone, replace it.
