FAQ
Boiler Service in Sarnia: 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?
During cold snaps we triage, households with no heat at all go first. Typical timeline from call to warm house is same day to next morning.
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.

“Our gas fireplace pilot kept dying every cold night, and the tech traced it to a worn thermocouple, replaced it same visit, and relit everything perfectly.”
