Frequently Asked Questions

My furnace won't turn on — what could be wrong?

This is often an ignition or burner issue, but it can also point to a control board, sensor, or gas supply problem. We diagnose the exact cause before recommending a repair.

Is it safe to keep running a furnace that's making noise?

Unusual noises often signal a mechanical issue — a failing blower motor, loose component, or worn part. It's worth having it checked before it leads to a bigger repair or a safety concern.

Do you repair furnaces you didn't install?

Yes. We service and repair all major brands and models, regardless of who installed them originally.

How quickly can you get to a repair?

We prioritize no-heat and safety-related calls and aim to get to most repairs quickly, especially during cold weather. Contact us and we'll confirm the soonest available time.
