Quick answer
- Planning ranges (including /pricing) are framing tools — not firm contracts.
- On-site diagnosis locks parts, labor, and scope.
- Second opinion when you already have a bid.
When this applies
No heat on a cold Central Valley morning
You need diagnosis, not a national average for “furnace repair.”
You are deciding repair vs heat pump replacement
Rebate timing and duct condition matter — AI will not reconcile them to your attic.
Options to evaluate
Component repair on a sound heat exchanger
Often the honest win. Tradeoff: older efficiency remains.
Furnace replacement
When HX or age/safety says so. Tradeoff: still consider heat pump alternative.
Heat pump conversion
Electrification path with rebate verification. Tradeoff: electrical capacity check required.
Failure modes to avoid
AI recommending a filter change for a hard no-ignition fault
Filters matter — they are not every failure mode.
Pricing a heat exchanger replacement like a capacitor
Different risk category. Safety findings change the recommendation entirely.
Ignoring venting and combustion air on replacements
Category I/IV vent changes are field-engineered, not chat-engineered.
Skipping CO checks after “successful” repair narratives online
Instruments beat anecdotes.

FAQs
Can AI tell if my heat exchanger is cracked?
No. That takes inspection — visual, camera, and combustion analysis as appropriate.
Why do heating estimates vary so much?
Repair vs replace vs heat pump are different projects. Make bidders label which one they priced.
Is the pricing planner for furnaces too?
Yes for planning bands. Firm work still needs the tech in the mechanical room.
What about dual-fuel systems?
Controls and sizing interactions are site-specific — another reason averages fail.
