Annual furnace maintenance prevents breakdowns, improves efficiency, and extends the life of your system. Our tune-up covers everything from heat exchanger inspection to filter replacement and safety testing.

Common Furnace Problems

If your furnace is blowing cold air, short cycling, making strange noises, or showing a yellow flame instead of blue, it needs professional attention. A yellow flame can indicate a carbon monoxide risk and should be addressed immediately. Other signs include rising heating bills despite normal usage, uneven heating between rooms, and frequent thermostat adjustments. Our TSSA-certified technicians diagnose and repair all furnace makes and models.

FAQs

Common Questions

How long does a furnace last?

A well-maintained furnace typically lasts 15–20 years. If yours is approaching this age, it's worth considering an upgrade to a more efficient model.

Why is my furnace blowing cold air?

This could be caused by thermostat issues, a dirty air filter, pilot light problems, or a malfunctioning flame sensor. Call us for a professional diagnosis.

How much does a new furnace cost?

Furnace costs vary based on size, efficiency rating, and features. We provide free in-home estimates and offer flexible financing.

Should I repair or replace my furnace?

If your furnace is over 15 years old, requires frequent repairs, or your energy bills are rising, replacement is often more cost-effective.

What AFUE rating should I look for in a new furnace?

For Toronto's climate, we recommend a minimum 96% AFUE rating. This means 96 cents of every energy dollar goes directly to heating your home. High-efficiency furnaces qualify for Enbridge rebates and pay for themselves through lower gas bills within 3-5 years.

How do I know if I need a new furnace or just a repair?

Consider replacement if your furnace is over 15 years old, needs frequent repairs, uses R-22 refrigerant, or your heating bills keep climbing despite maintenance. If the repair cost exceeds 50% of a new unit's price, replacement is usually the smarter investment.
