“Booked a service because the pilot flame looked weak and orange. He tuned the burner, adjusted the pilot, and now the glass stays clean and the heat is noticeable.”

Boiler Repair, Installation & Maintenance in Oshawa
Many Oshawa homes heat with hydronic boilers, and Oshawa Heating & Cooling repairs, installs, and maintains them across the area. From an older cast-iron gas boiler in a mature neighborhood to a quiet high-efficiency condensing unit in a newer build, our technicians keep radiator and in-floor systems running through the coldest months.
Why Homeowners Call Us
No hot water because the boiler keeps shutting itself off?
From a cast-iron gas boiler in an older Oshawa home to a condensing unit in a new build, we repair no-heat, leak, and pressure faults fast, with upfront pricing and the same crew each visit.
Fast No-Heat and Leak Repairs
Cold radiators, a leaking relief valve, or a boiler losing pressure are common as systems age. We find the real fault, igniter, circulator, or expansion tank, and repair it without pushing an unnecessary replacement.
High-Efficiency Boiler Installation
When an old boiler is past saving, we install right-sized high-efficiency condensing gas boilers matched to your radiators or in-floor loops, sized so the whole Oshawa home heats evenly and efficiently.
Annual Maintenance and System Flush
A yearly service and hydronic flush keep your boiler efficient and catch corrosion before it fails. We service gas boilers across Oshawa and the surrounding area so your system is ready for winter.
FAQ
Boiler Service in Oshawa: Common Questions
How much does boiler service cost in Ontario?
Expect three possible numbers: a diagnostic fee, a repair price, or a replacement quote. Most calls end at the first two, and we explain all three first.
How quickly can you fix a boiler with no heat?
Most no-heat faults come down to ignition, a lockout, or a failed circulator, all fixable on the first visit. Special-ordered parts usually land within a day or two.
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.

“I wanted a basic tune up and the technician respected that. He cleaned and tested everything, flagged one worn part without any pressure, and the system has never run smoother.”
