My furnace won’t start—what should I check first?

Confirm the thermostat is set to Heat and the setpoint is above room temperature, ensure the furnace switch and breaker are on, and check for a recently changed air filter. If it still won’t fire, book a diagnostic so we can safely test ignitor, flame sensor, and controls.

What happens during a furnace diagnostic?

We verify gas pressure, test the ignitor and flame sensor, check safety switches, inspect the heat exchanger, and measure CO. You’ll receive a written report with the fault and a flat-rate repair price.

Do you service all furnace brands?

Yes. We repair and maintain major gas furnace brands including Rheem, Lennox, Amana, Goodman, York, and more. Our trucks carry the most common parts for faster fixes.

Should I repair or replace my furnace?

We consider age, repair cost, and safety. For older units with high-cost items like a cracked heat exchanger or failed control board, replacement may be the better investment—especially with today’s efficient, variable-speed models.

Why does my furnace smell or make banging noises?

Odours can be dust burning off or a sign of a blocked vent. Banging can indicate duct expansion or delayed ignition. Turn off the system and schedule a safety check if the smells or sounds are persistent.

Your Questions, Answered

What brands of furnaces do you repair?

We service all major brands including Rheem, Lennox, Amana, Goodman, Carrier, York, and more. If parts are available, we can fix it.

How often should I service my furnace?

Once per year. Annual maintenance keeps efficiency up, reduces failures, and is often required to maintain parts warranties.

Can a dirty filter cause a breakdown?

Yes. Restricted airflow can overheat the furnace and trip safety switches. Replace 1” filters every 1–3 months, 4–5” filters every 6–12 months.

What’s the typical furnace lifespan in Ottawa?

With proper maintenance, 15–20 years is common. Harsh winters and poor care can shorten that range significantly.

Do you offer financing on new furnaces?

Yes. We offer flexible options to spread out the cost of a replacement. Ask us during your quote for current plans and promotions.
