“Furnace refused to ignite on the first really cold morning. They diagnosed the failed igniter from my description, arrived with the part on hand, and we were warm by lunch.”

FAQ
Boiler Service in Waterloo: Common Questions
How much does boiler service cost in Ontario?
Service calls are priced by the visit and repairs by the part and labour. Tune-up, targeted repair, or replacement, the estimate for each is free before you commit.
How quickly can you fix a boiler with no heat?
Fast. Lockouts and ignition failures are usually a same-visit fix, and our vans carry the parts that cause most winter no-heat calls. You will know the timeline before we start.
Should I repair my old boiler or replace it?
Safety changes the answer. A boiler leaking water or showing flue gas problems gets replaced, not patched. Otherwise a healthy unit with a cheap fault deserves one more repair.
