FAQ

Common Questions

Real answers to the questions Mississauga homeowners ask us most.

How do I know if my furnace needs to be repaired or replaced?

+

If repair costs less than 50% of a new unit and your furnace is under 15 years old, repair is usually smarter. We'll give you an honest recommendation.

How quickly can you come out for an emergency repair?

+

Call (437) 999-4242 any time. We are open 24 hours and work to dispatch a technician as fast as we can.

How often should I have my furnace serviced?

+

Once a year, ideally in the fall. Annual maintenance extends lifespan, keeps your warranty valid, and catches problems early.

What's the difference between a tank and tankless water heater?

+

Tank heaters are cheaper upfront but less efficient. Tankless heaters save energy and last 20+ years. We'll help you choose.

Why is my house not heating evenly room to room?

+

Usually caused by blocked ductwork, dirty filters, or an undersized furnace. A diagnostic visit will pinpoint the cause.

What should I do if my furnace stops working in the middle of the night?

+

Check your thermostat and filter first. If that doesn't help, call (437) 999-4242. We're available 24/7.
