Fast, Reliable Furnace Repair When You Need It Most

Common Furnace Issues & When to Call for Repair

If your furnace is making strange noises, heating unevenly, cycling frequently, or causing your energy bills to spike, it may be time for a repair. Discoloured flames (anything other than blue) could also indicate a serious safety issue like carbon monoxide. Most repairs are straightforward when caught early, and our certified technicians are here to help.

Repair vs. Replace: What’s the Smart Choice?

Most furnaces last 15–20 years. If your unit is under 10 years old and the repair costs less than 1/3 the price of a new one, it’s often worth fixing. But if you’ve already made multiple service calls or your system is aging, a replacement may be the more cost-effective long-term solution. We’ll help you weigh your options with clear, honest advice.

Red Tags, Safety & Legal Requirements in Ontario

Only licensed professionals can perform gas furnace repairs in Ontario. If your furnace receives a red warning tag, that means it poses a safety risk:

Type A: Immediate hazard – gas shut off required
Type B: Must be fixed by a set date or gas will be shut off

If you’ve received a red tag, contact us right away. We can repair the issue quickly or provide a second opinion — all with full TSSA certification.
