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 keeps the system cleaner and catches common 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.
