Hot water boilers are reliable heating systems, but when they fail you need a technician who understands hydronic heating inside and out. Imperial Heating provides same-day boiler repair across Toronto and the GTA for gas, electric, and oil boilers. Licensed technicians, upfront pricing, and emergency service available around the clock.
Same-day service available
A boiler that runs without annual servicing is more likely to break down, lose efficiency, and develop safety issues. Regular maintenance catches small problems before they become expensive repairs.
Full inspection of the heat exchanger for cracks and corrosion
Check and adjust boiler pressure to manufacturer specifications
Test all safety controls including pressure relief valve and low-water cutoff
Inspect and clean the burner assembly and pilot or ignition system
Flush and bleed radiators to remove trapped air and sludge
Test circulator pump operation and check for leaks at seals
Verify thermostat accuracy and calibrate if needed
Inspect flue and venting for blockages or deterioration
Our technicians diagnose and repair these issues daily. Most boiler repairs are completed in a single visit.
The most common boiler complaint. Causes range from a failed motorized valve or diverter valve to a broken thermostat, low water levels, or a faulty pump. We diagnose the root cause and restore heat quickly.
Leaks can originate from corroded pipes, a failing pressure relief valve, pump seals, or internal corrosion. Even small leaks cause significant damage over time. We locate the source and repair or replace the affected component.
A rumbling or banging sound from the boiler usually means limescale buildup on the heat exchanger, restricting water flow and causing overheating. We flush the system and descale the exchanger to restore quiet, efficient operation.
If the pressure gauge reads below 1 bar, your system cannot circulate hot water effectively. Common causes include a water leak in the system, a recently bled radiator, or a failing expansion vessel. We repressurize and fix the underlying issue.
A pilot light that will not stay lit points to a faulty thermocouple, a blocked pilot jet, or a draught issue. On older boilers, this is one of the most frequent service calls. Our technicians resolve it in a single visit.
Cold patches on radiators typically indicate trapped air, sludge buildup in the system, or a failing circulator pump. We bleed the radiators, power flush the system if needed, and verify even heat distribution across every room.

Your technician inspects the boiler, runs diagnostic tests, and identifies the root cause. We explain the issue in plain language before any work begins.
You receive a written quote with parts and labour itemized. No work starts until you approve. No hidden fees or surprise charges.
We complete the repair using manufacturer-grade parts. Most boiler repairs are finished within 1 to 2 hours on the first visit.
We run the boiler through a full heating cycle, verify proper operation, and provide a written warranty on the repair.
Boilers generally last longer than forced-air furnaces, with many systems running 20 to 30 years. But there comes a point where replacement is the smarter investment.
Our technicians will always give you an honest recommendation. We will never push a replacement when a repair will solve the problem. If replacement is the better option, we offer flexible financing and can install a modern high-efficiency condensing boiler that significantly reduces your monthly gas bills.

Toronto homes use a range of boiler types depending on the age of the building and the heating system design. Our technicians are trained to work on all of them.
The most common type in the GTA. Gas boilers heat water using natural gas and distribute it through radiators or in-floor radiant tubing. We handle everything from burner issues to gas valve replacement and heat exchanger repairs. All work performed by G2/G3 licensed gas technicians.
Electric boilers are common in condos and smaller homes without gas lines. They are quieter and require less ventilation, but can still develop issues with heating elements, thermostats, and circulator pumps. We diagnose and repair all electric boiler brands.
Still found in many older Toronto and East York homes. Oil boilers require specialized knowledge of fuel delivery systems, oil burner nozzles, and combustion chambers. Our team services oil-fired systems and can advise on conversion options if you are considering switching to gas.
High-efficiency condensing boilers recover heat from exhaust gases and can achieve efficiency ratings above 95%. They are increasingly popular in new builds and retrofits. We service all condensing boiler brands and handle common issues like condensate drain blockages and flue problems.
Most boiler repairs are completed the same day you call. No waiting days without heat or hot water.
Boilers require different expertise than forced-air systems. Our technicians specialize in hot water heating, radiators, and in-floor radiant systems.
