Boiler Repair & Service in Aurora
Hot water and radiant boiler diagnosis, service and controls work by gas-licensed technicians.
Hydronic heating is quieter, more even and longer-lived than forced air, but far fewer technicians are genuinely comfortable with it. Our boiler crew works on hot water, radiant and steam systems in older GTA homes every week.

Local context
Boiler Service for Aurora homes
What we find on a boiler service call in Aurora depends almost entirely on when the house was built. Executive homes east of Bayview commonly run three or four gas fireplaces — great room, primary bedroom, basement and sometimes an outdoor unit. We service them in one visit so you are not paying a trip charge four times.
Boiler faults are usually in the water side rather than the fire side: a waterlogged expansion tank, a seized circulator, air in the loop, a failed zone valve or a slow leak dropping system pressure. Chasing the burner when the problem is a flooded expansion tank is the most common misdiagnosis we get called in behind.
Annual service on a boiler is not the same job as a furnace tune-up. We check system pressure against static head, test the relief valve, verify the low-water cutoff on applicable systems, bleed and balance the loops, inspect the heat exchanger and confirm combustion. A well-serviced boiler routinely outlives two forced-air furnaces.
Boilers fail quietly compared with forced-air systems. Instead of stopping outright they lose output — one zone goes lukewarm, radiators need bleeding more often, or the system pressure creeps up and dumps through the relief valve. By the time a boiler stops entirely, the underlying fault has usually been developing for a season or more, which is why we check circulator operation, expansion tank charge and system pressure on every visit rather than only the reported symptom.
Hydronic systems also punish neglect in ways air systems do not. Oxygen ingress through an undersized or waterlogged expansion tank corrodes the heat exchanger from inside, sludge settles in low points and blocks circulation, and a partially closed zone valve will imitate a failing circulator perfectly. We test the system as a loop, not as a box on the wall.
What the housing stock in Aurora means for this job
The village core is late-1800s and early-1900s brick with tall unlined masonry stacks. Regency Acres and Aurora Heights are post-war bungalows on their second furnace. Bayview Northeast, Aurora Grove and the Estates pockets are 1995-onward two-storey builds with multiple zero-clearance fireplaces, HRVs and high-efficiency condensing furnaces. For boiler service, that matters because the work concentrates on the loop, not just the boiler — and that is exactly what changes between a Rural Aurora property and a newer build in Aurora Estates.
Timing in Aurora
Most boiler faults surface on the first sustained cold week, when zones that coasted through mild weather are asked to hold temperature continuously. In Aurora specifically: Aurora shares Newmarket's moraine exposure, and the open ground east of Bayview gets wind-driven snow that packs against low sidewall vent terminations. Blocked direct-vent terminals are a recurring January call here.
What it costs here
Circulators, zone valves and expansion tanks are routine parts; heat exchangers, control boards and full system flushes are where the cost steps up. Larger Bayview-side homes carry longer flue runs and multiple appliances, which raises the total but lowers the per-appliance price when everything is done in a single visit. Heritage-core repointing and crown rebuilds cost more because of scaffolding and mortar matching.
Permits and jurisdiction
The Town of Aurora issues building permits and heritage approvals in the core; gas work is TSSA-governed, and any solid-fuel appliance change should be documented with a WETT inspection for insurance.

What affects boiler service pricing in Aurora
- Whether the fault is a control, a circulator, a zone valve or the heat exchanger
- Number of zones and how accessible the near-boiler piping is

FAQ
Boiler Service questions from Aurora homeowners
Why does my boiler keep losing pressure?
Almost always either a leak somewhere in the loop — often a slow one under a floor or at a radiator valve — or a failed expansion tank. We pressure-test rather than simply topping it up, because repeated top-ups introduce fresh oxygenated water and accelerate internal corrosion.
Some radiators are cold — is the boiler failing?
Usually not. Cold radiators with a working boiler point to air in the loop, a stuck zone valve, or a system that has never been balanced. All three are inexpensive compared with a boiler.
Should I replace my old cast-iron boiler?
Not automatically. A sound cast-iron boiler can run for decades and its heat exchanger long outlives modern equivalents. We compare current efficiency, condition and the real cost of a condensing conversion before recommending replacement.
How often should a boiler be serviced?
Annually, before the heating season. Hydronic systems are stable enough that faults develop quietly, which means the annual inspection is where most of them get caught.
Are hydronic systems common in homes here?
The village core is late-1800s and early-1900s brick with tall unlined masonry stacks. Regency Acres and Aurora Heights are post-war bungalows on their second furnace. Bayview Northeast, Aurora Grove and the Estates pockets are 1995-onward two-storey builds with multiple zero-clearance fireplaces, HRVs and high-efficiency condensing furnaces. On a boiler service visit in Rural Aurora, Aurora Estates, Regency Acres or anywhere else in Aurora, we work from what the house actually is rather than a standard checklist — the loop, not just the boiler gets assessed on the property, and you get the readings in writing.
When should a boiler be serviced each year?
Most boiler faults surface on the first sustained cold week, when zones that coasted through mild weather are asked to hold temperature continuously. Aurora shares Newmarket's moraine exposure, and the open ground east of Bayview gets wind-driven snow that packs against low sidewall vent terminations. Blocked direct-vent terminals are a recurring January call here. We cover Aurora from Rural Aurora through Regency Acres, and also serve 4 neighbouring municipalities, so scheduling outside a demand spike usually means a same-week window.
