Repair vs. replace
When the honest answer is "replace it."
A cracked heat exchanger is a safety issue — we won't patch it, and no honest tech will. And the 15-year rule: if your furnace is 15+ years old and the repair is more than roughly a third of replacement, replacement usually wins the math.
We'll do the math with you at the table — repair quote on one side, replacement tiers on the other, monthly payments underneath both. Your call, real numbers.
Most furnaces we see in north Aurora are 15–25 years old. If yours has needed two repairs in two winters, start pricing replacement — the third repair is usually the expensive one.

How much is the diagnostic fee?
TBD — trip, full diagnosis, and a written itemized quote. Approve the repair and it's credited toward the work.
Why is one company's quote double another's for the same repair?
Usually three reasons: part quality (OEM vs cheapest generic), whether the "repair" includes a real safety check, and whether the quote was bait. Compare written, itemized quotes — part numbers included — and the answer becomes obvious.
