Frequently Asked Questions
What is the most common problem with a furnace?
One of the most common furnace repairs is a faulty ignitor or flame sensor. Dirty filters, thermostat issues, and clogged burners are also frequent reasons homeowners call for furnace service and repair in Mississauga.
What is the most expensive repair on a furnace?
The most costly furnace fix is typically replacing a cracked heat exchanger or failed blower motor. These parts are vital to safe and efficient operation. When costs get high, we also provide honest advice about repairing furnace vs. replacement.
Why is my furnace not kicking on for heat?
This often points to a thermostat issue, tripped safety switch, or electrical failure. Our 24 hour furnace repair team will inspect your control board, ignitor, and gas supply to determine why your system won’t start.
Why is my furnace running but not heating?
If your furnace is running but not heating, it may have low gas pressure, a dirty flame sensor, or a faulty ignitor. These are fixable issues, and our furnace repair technicians can get your heat back quickly.
Why is my furnace blower staying on but no heat?
A blower staying on without producing heat often signals a high-limit switch failure or control board issue. This is a common issue we see in residential furnace repair, and we can diagnose it on the spot.
Where is the reset button on a furnace?
The furnace reset button is usually located inside the blower compartment, near the motor housing. If you’ve had to press it more than once, call us for a furnace service repair—your system may have a deeper fault.
Do you repair all furnace brands?
Absolutely. Our furnace repair technicians work with all major makes and models, including Lennox, Carrier, Trane, Goodman, and more. We also handle electric furnace repair, wall units, and high-efficiency models.
Is it better to repair or replace an older furnace?
If your unit is 15+ years old and requires frequent repairs, it may be time for a replacement. However, we’ll always try to repair furnace issues first and provide honest advice based on cost and condition.
Can you fix my furnace if it’s an older model?
Yes, we specialize in old furnace repair. Our team is trained in both modern and legacy systems, including floor furnace repair, electric units, and older gas models still common in Mississauga homes.
