“Our furnace kept locking out with an ignition error code. The technician walked me through what the sequence should look like, corrected the fault, and stayed to confirm several cycles.”

Boiler Repair, Installation & Maintenance in Waterloo
Waterloo has a mix of heritage homes with original boiler systems and newer builds with high-efficiency installs, and Waterloo HVAC Pros services them all. We repair and replace cast-iron gas boilers in older homes and condensing modulating units in newer ones, radiator or in-floor.
Why Homeowners Call Us
Heritage Waterloo home with an aging cast-iron boiler acting up?
A lockout code only tells part of the story. We read the whole system, reset what is safe, and repair the fault behind it.
Leaking Boilers Handled Before Damage Spreads
A slow weep from a seal or valve can wreck flooring and basements finished around the boiler. We isolate the leak, repair what is repairable, and give you a straight answer if the section itself is cracked.
Water Treatment and Loop Protection
Dirty loop water is the number-one killer of condensing boilers. We test and treat system water, install dirt separators where needed, and keep inhibitor levels right so your heat exchanger and circulators live their full life.
Quotes With No Surprises Attached
You approve the number before we start, and the number does not change. Diagnostic findings get explained with photos, options get priced side by side, and nobody here earns a commission on selling you a boiler.
FAQ
Boiler Service in Waterloo: Common Questions
How much does boiler service cost in Ontario?
Diagnostics are quoted up front, and common repairs like valves, igniters, and circulators fall into a predictable range. You get the exact price in writing before work begins.
How quickly can you fix a boiler with no heat?
If the igniter or pilot is the problem, warm radiators return within hours. Bigger failures like heat exchanger leaks take longer, and we say so plainly up front.
Should I repair my old boiler or replace it?
Compare the repair bill to yearly fuel savings from a 95 percent efficient condensing boiler. With a payback under eight years and an aging unit, replacement wins.
