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
Your AC stopped cooling and an online quote feels too tidy
Tidy averages hide compressor-level outcomes.
You want a second opinion on a repair invoice
Bring the diagnosis — /free-second-opinion.
Options to evaluate
Diagnostic visit → targeted repair
Pay for truth first. Tradeoff: diagnostic fee applies toward repair when you proceed (per current policy on your quote).
Repair vs replace decision on older systems
AI cannot smell a burned contactor or see oil traces. Tradeoff: you may leave with both numbers.
Planning range from /pricing, firm price after diagnosis
Use the planner for expectations; use the tech for authorization. Tradeoff: two-step process beats surprise invoices.
Failure modes to avoid
Authorizing a “capacitor special” without amp draw and temperature splits
The capacitor may be bad — and not the only problem.
Chatbot insisting your SEER rating determines repair cost
Efficiency stickers do not price a failed fan motor.
Ignoring refrigerant platform and leak probability
A recharge without leak finding is often a subscription to the same failure.
Skipping electrical safety checks on a “simple” no-cool
Burned connectors and weak contactors are field findings, not prompt outputs.

FAQs
Can ChatGPT tell me if I need a compressor?
It can list symptoms. It cannot measure amp draw, suction pressure, or condenser TD on your unit. That is the job.
Is your pricing page useless for repairs then?
No — it frames planning ranges so you are not flying blind. Firm authorization still follows diagnosis.
Do you charge to tell me it is not worth repairing?
Diagnostics are real work. We present repair and replace paths honestly when the math flips.
What if another company already quoted a part?
Use /free-second-opinion — we re-check the diagnosis, not just the margin.
