Furnace repair in Bowmanville, usually same or next day.

Cold air, short cycling or no flame

Many no-heat calls come down to a handful of parts: a dirty flame sensor, a worn igniter, a pressure switch, a blocked condensate drain or a blower that won't start. We watch how your natural gas or propane furnace starts, runs and shuts off, because that sequence shows which part to test. You pay to fix the fault that's actually there, not for parts swapped on a hunch.

The price before any work starts

Quotes are free. Before any repair begins, you'll hear what failed, what the fix involves and what it costs, in plain language. If a part has to be ordered, you'll know how long it should take. Nothing gets added without your OK, and the repair carries a Platinum Gas workmanship warranty, so if the same problem comes back, you know who to call.

If a repair makes sense, that's what you'll be quoted. If the furnace keeps breaking down, we'll tell you when it's time to price a replacement. Annual tune-ups are matched to your model, and any problem you mention gets checked on the same visit. Platinum Gas is based in Bowmanville and works across Courtice, Newcastle, Oshawa, Whitby, Port Hope and Cobourg, including rural homes on propane. The quickest way to start is a text with a photo of the furnace's rating label and any blinking light code.

No heat or short cycling

Furnace won't start or keeps shutting down?

A furnace may fail to ignite, run briefly then stop, or leave the blower running without useful heat. Describe what starts and stops, and share any displayed error code with the model information.

We check the operating sequence and relevant components to identify the fault. Avoid repeated resets or bypassing a safety control; they can obscure the problem and allow unsafe operation.

Annual furnace maintenance

Have the furnace inspected before heating season.

Annual professional care follows the manufacturer's requirements for your furnace. The visit considers its condition and operation, with checks, cleaning and adjustments listed in the quoted scope.

Mention changes in noise, ignition or heat delivery when you book. Keep the service record and follow the specified filter instructions between visits, with access around the furnace kept clear.

Repair or replacement assessment

Compare the repair with the furnace's condition.

The repair decision depends on the diagnosed problem, parts availability, repair history and how the equipment suits the home. Recurring faults can justify reviewing the cost and scope of replacement.

We explain the proposed repair and any remaining concerns before further work. If replacement is worth considering, its equipment, connections and installation are quoted as a separate project.

How furnace diagnosis and service work


  1. Send the model and operating problem

    Share the visible code, timing, fuel and thermostat behaviour. Note recent outages or work around the furnace, and do not remove panels or repeatedly reset it.


  2. Review the findings and approve the work

    We assess how the furnace starts and runs, then explain the repair or maintenance scope, price and parts availability. Additional work requires your approval.


  3. Check operation and confirm follow-up

    After completing approved work, we check the result and explain any remaining issue or further visit required. Keep the service details and follow the furnace's maintenance instructions.

Furnace repair questions

How to describe a furnace problem safely, what determines the repair scope and what to do in a gas or carbon-monoxide emergency.

What should I send for a no-heat furnace request?

Send your location, furnace make and model, fuel and any code you can see safely. Describe what happens when the thermostat calls for heat, when it stops and whether the problem repeats. Mention recent power interruptions, renovations or equipment changes and the last service date if known.

Should I keep resetting a furnace that will not stay on?

Avoid repeated resets and never bypass a safety control. Record the visible code and operating sequence, then follow the manufacturer's instructions while arranging service. If you smell gas, a carbon-monoxide alarm sounds or another emergency develops, leave and seek emergency help immediately.

Is furnace maintenance the same for every model?

The tasks depend on the manufacturer's instructions and the condition of the furnace, venting, controls and supply. Your quote identifies included checks, cleaning and adjustments. Report an active fault when booking maintenance so the visit can account for diagnosis and any separately approved repair.

What should I do if I smell gas or a carbon-monoxide alarm sounds?

Leave the area and call 911 from a safe location. For natural gas, also call Enbridge Gas at 1-866-763-5427. For propane, call your propane supplier's emergency number. Do not wait for a website reply or re-enter until emergency personnel say it is safe.

What affects the cost of furnace service?

Diagnostic findings, furnace model, access and required parts determine repair cost. Maintenance pricing depends on the tasks included for the equipment. If replacement is discussed, it is a separate quote covering the furnace and installation requirements.

What care is needed after a furnace repair?

Keep the service date and repair details, and arrange annual professional inspection. Follow the model's filter instructions and keep access clear. If the problem returns, report the code and sequence rather than repeatedly resetting it. Internal repairs and safety controls should be left to the technician.
