Common Questions

Heating FAQs

How often should I have my furnace serviced? +
We recommend annual furnace tune-ups, ideally in the fall before heating season. Regular maintenance extends equipment life, improves efficiency, and prevents unexpected breakdowns during cold Michigan winters.
My furnace is running but not heating — what's wrong? +
This is usually caused by a dirty air filter, a faulty thermostat, a tripped limit switch, or a malfunctioning igniter. Our technicians can diagnose and repair the issue same-day in most cases.
How long does a furnace typically last? +
A well-maintained furnace typically lasts 15–20 years. If your system is over 15 years old and requiring frequent repairs, a replacement is often the more cost-effective long-term solution.
Do you offer financing on new furnace installations? +
Yes — we work with financing partners to offer flexible payment options on new heating system installations. Contact us for details and to find out what you qualify for.
Do you service Windsor, Ontario as well? +
Absolutely. We have a dedicated Canadian team serving Windsor and Essex County. Call our Windsor line at (519) 990-0846 for service in Ontario.
