Furnace Repair FAQ

Get answers to common questions about our professional furnace repair services in Thornhill and the Greater Toronto Area

Serving Thornhill & GTA

What are common signs my furnace needs repair?

Common signs include unusual noises (banging, screeching, rumbling), weak airflow, inconsistent heating, frequent cycling, yellow pilot light (should be blue), increased energy bills, or the furnace not turning on at all.

Do you offer emergency furnace repair?

Yes! We provide 24/7 emergency furnace repair services throughout Thornhill and the GTA. No heat during winter is an emergency, and we prioritize these calls. Our technicians can typically respond within 2-4 hours.

What furnace brands do you repair?

We repair all major furnace brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Bryant, and more. Our technicians are factory-trained on multiple brands and carry common parts to complete repairs quickly.

How much does furnace repair cost?

Repair costs vary based on the issue, parts needed, and furnace type. We provide upfront pricing before any work begins with no hidden fees. Diagnostic fees may apply but are often waived if you proceed with the repair.

Should I repair or replace my furnace?

Consider replacement if your furnace is over 15 years old, requires frequent repairs, or repair costs exceed 50% of a new unit's price. Our technicians will provide honest recommendations based on your specific situation and budget.

Do your furnace repairs come with a warranty?

Yes! All our furnace repairs come with a warranty on both parts and labor. Warranty periods vary by repair type and parts used. We stand behind our work and will return to fix any covered issues at no additional cost.

How can I prevent furnace problems?

Annual furnace maintenance is the best prevention. Regular tune-ups improve efficiency, extend system life, and catch small issues before they become expensive repairs. We recommend scheduling maintenance every fall before heating season.

What should I do if my furnace stops working?

First, check your thermostat settings and ensure the furnace switch is on. Check your circuit breaker and replace the air filter if dirty. If these don't resolve the issue, contact us immediately for professional diagnosis and repair.
