“Pilot would not stay lit for days. A knowledgeable technician cleaned the flame sensor, explained why it kept shutting off, and we have had steady ignition ever since.”

FAQ
Boiler Service in Guelph: Common Questions
How much does boiler service cost in Ontario?
It depends on the fault. A failed igniter or relief valve is a modest repair, a leaking heat exchanger is not. We diagnose, then quote, and the quote is free.
How quickly can you fix a boiler with no heat?
Same-day response is the norm for no-heat calls in heating season. Diagnosis takes under an hour, and the fix follows immediately when the part is on the truck.
Should I repair my old boiler or replace it?
One repair is maintenance, a third repair in two winters is a message. We lay both costs side by side, including fuel savings, and let you decide.

“I noticed ice on the copper lines and weak airflow. The tech diagnosed a refrigerant leak, walked me through the options with pricing up front, and finished the same day.”
