Any Questions

How often should I service my furnace and air conditioner?

We recommend professional maintenance twice a year — your furnace in the fall before winter, and your air conditioner in the spring before summer. Regular tune-ups keep your system efficient, prevent unexpected breakdowns, and are often required to keep your manufacturer warranty valid.

How often should I change my HVAC air filter?

For most homes, every 30 to 90 days. If you have pets, allergies, or run your system heavily, change it closer to every 30 days. A clean filter improves airflow, lowers your energy bills, and protects your system from unnecessary strain.

Do you offer 24/7 emergency service?

Yes. We provide around-the-clock emergency furnace and AC repair across Toronto and the GTA — including evenings, weekends, and holidays. A no-heat night in winter or a failed AC in a summer heatwave is never something that should wait.

Should I repair or replace my furnace or AC?

It depends on the system's age, the cost of the repair, and its efficiency. As a general guide, if your system is over 12–15 years old and facing a major repair, replacement is often the smarter long-term investment. Our technicians give you honest advice — we'll only recommend replacement when it truly makes sense.

Are your technicians licensed and insured?

Yes. Our technicians are fully licensed, TSSA-certified, and insured — trained and background-checked to work safely on furnaces, ACs, and heat pumps across Ontario.
