Explaining repair-versus-replace so a homeowner can actually decide
The hardest conversation in residential HVAC isn't technical — it's the kitchen-table moment where a homeowner has to choose between a $2,400 repair on an aging system and a $7,000 replacement, and they suspect you're upselling. Terms like static pressure, refrigerant phase-out, and system sizing mean nothing to someone who just wants the house cool again. AI is good at translating your findings into a fair, plain-language rundown — as long as it explains, and you decide.
You are helping a licensed HVAC technician write a clear, honest message to a homeowner explaining their repair-versus-replace options. Keep it balanced — the goal is an informed customer, not a hard sell. What I found (my diagnosis): {{diagnosis}} The options with MY prices: {{options}} About the customer: {{customer_context}} Write a message that: - Explains the problem in plain language, translating any technical term in a few words. - Lays out each option I gave — what it costs, what it fixes, and roughly how long it buys them — using ONLY my prices and facts. - Includes a neutral "what happens if you do nothing" line based on what I described. - States my recommendation ONLY if I included one; otherwise presents the options evenly and says the choice is theirs. Hard rules: - Use only the findings and prices I provided. Do not invent efficiency percentages, energy-bill savings, rebate amounts, equipment lifespans, or refrigerant facts. If a number would strengthen the message, write [VERIFY: what] instead of inventing it. - No pressure language, no scare tactics. Warm, straightforward, under 180 words.

Hi — here's where things stand, plain and simple. Your furnace has a cracked heat exchanger, which is the part that keeps combustion gases separated from the air you breathe. Because a crack there can let carbon monoxide into the home, I've shut the unit down for safety. Two options: I can install a used replacement exchanger for about $1,900, which would likely buy 2-3 more years on a 12-year-old furnace. Or a new high-efficiency furnace runs $5,600 installed and should last 15-20 years. If nothing is done, the furnace can't be safely run. Both are fair choices depending on how long you plan to stay — happy to talk it through.
The full workflow
- Write your diagnosis and both prices in shorthand, without the customer's name or address.
- Run the prompt and read it back against what you actually found on site.
- Clear any [VERIFY] flag with a real number before sending.
- Send from your own phone or email so the personal details never touch the AI tool.
Watch out for
Never let AI generate the safety call or the diagnosis — whether a cracked heat exchanger is safe to run, or what refrigerant a system needs, is your licensed judgment from actual inspection, not a model's guess.
AI will invent efficiency percentages, utility-rebate amounts, and equipment lifespans that sound authoritative — verify every number, since a wrong savings claim to a customer is a consumer-protection problem.
Strip names, addresses, and account details before pasting anything; consumer AI tools may retain what you enter.
