Boiler repair in Peterborough & the Kawarthas.

A furnace heats air and blows it through ducts. A boiler heats water and circulates it through radiators, baseboards, or in-floor tubing. Boiler heat is quieter and more even, with no forced air moving dust around, but the systems are different enough that not every HVAC company services both. We do.

Well-maintained boilers commonly run 15 to 30 years, considerably longer than a typical furnace. Annual service is a large part of why, since scale, corrosion, and pressure problems do their damage slowly.

Usually trapped air in the system. Bleeding the radiators often fixes it, and it is something many homeowners can do themselves. If they cool again quickly, or if system pressure keeps dropping, there is likely a leak or an expansion tank problem worth having looked at.

Pressure that keeps falling points to a leak somewhere in the loop, a failing pressure relief valve, or a waterlogged expansion tank. Topping it up repeatedly treats the symptom. We find the actual cause.

Kettling is usually scale buildup on the heat exchanger causing water to boil in spots where it should not. Banging in the pipes is often trapped air or thermal expansion. Neither is an emergency on its own, but both are worth diagnosing before they worsen.

Yes. We service hydronic and radiant systems including in-floor tubing, manifolds, zone valves, and circulator pumps, for both residential and commercial buildings.

Annually, before the heating season. Service covers combustion, pressure, the expansion tank, circulator pumps, zone valves, safety controls, and venting.

Yes, including converting older systems to modern high-efficiency condensing boilers. We will walk you through what the existing piping and venting will and won't support before you commit to anything.
