What it does

The hot-surface ignitor glows to light the burners on a gas furnace. When it cracks, the furnace tries and fails to light.

Why it fails in Phoenix

Even in Phoenix, furnaces run on winter mornings, and ignitors are brittle and fail from thermal cycling. A fair quote includes handling and testing, since the part itself is inexpensive.

Questions

What should the quote include?

A fair quote covers the diagnostic visit, the part, licensed labor, and a written parts-and-labor warranty. Ask for the part number — with it, the price is checkable.

Why do quotes for this vary so much?

Brand of part, warranty length, after-hours timing, and how hard your system is to access all legitimately move the number. That is why we show a range rather than a single price.

Is the diagnostic fee extra?

It varies. A fair quote credits the diagnostic fee toward the repair if you approve the work — ask before the tech starts.
