Furnace Repair Questions Answered
Common questions about furnace repair from homeowners throughout Central Ontario.
What is a Red Tag and do you offer second opinions?
A Red Tag is issued by a gas technician when they find a safety concern with your gas equipment. If you've received a Red Tag from another company, we offer complimentary second opinions. We'll inspect your equipment independently and give you an honest assessment. Many homeowners find that getting a second opinion provides clarity and can sometimes reveal that a less expensive solution exists.
Why is my furnace not producing heat?
Common causes include a tripped circuit breaker, thermostat issues, pilot light or ignitor problems, faulty flame sensor, blower motor failure, or gas supply issues. Our technicians diagnose the exact cause rather than guessing.
How much does furnace repair typically cost?
Costs vary by issue. Simple repairs like ignitor replacement typically run $150-300. More complex repairs involving blower motors or control boards can be $400-700+. We provide exact quotes before any work begins. As an Air Source Member, your diagnostic service call is complimentary and you save 15% on all parts and labour.
Should I repair or replace my old furnace?
Generally, if your furnace is over 15 years old and repair costs exceed 50% of a new unit, replacement often makes more sense financially. We provide honest, no-pressure advice based on your specific situation.
How quickly can you respond to a furnace emergency?
For no-heat emergencies, our average response time is under 60 minutes throughout our service area. We understand that every minute without heat matters in Canadian winters.
My furnace is making strange noises. Is that dangerous?
Some noises indicate serious issues that shouldn't wait. Banging can mean delayed ignition (dangerous). Squealing often indicates belt or motor problems. Rattling might be loose components. We recommend calling for any unusual sounds.
Do you repair all brands of furnaces?
Yes, we service all major furnace brands including Lennox, Carrier, Trane, Goodman, Rheem, Bryant, American Standard, and more. Our technicians are trained on both older and current models.
