A complete, professional service report you can paste into your work order or send to the customer — written from just a few bullet points about what you found and did.
Write a professional HVAC service report for a residential customer. Job details: [equipment brand and model], [what the problem was], [what you did to fix it], [any parts replaced], [recommendations for next time]. Keep it clear and professional.
View full prompt →Tip: Include the equipment brand and model — accuracy improves significantly with specific details. Add "keep it under 150 words" if the output is longer than your work order field allows, or "include system readings" if you took measurements you want documented.
A plain-language explanation of a technical HVAC issue that you can read to the customer or use as talking points — no jargon, just a clear description of what's wrong and why it needs to be fixed.
Explain to a homeowner why [technical problem, e.g., "a failed capacitor prevents the AC from starting"]. Use simple language, explain why it matters, and why waiting to fix it could make things worse. Keep it under 100 words.
View full prompt →Tip: Add "and explain why the price is fair" if you need help justifying the estimate — it turns a complaint-prone moment into a trust-building one. Keep the cap at 100 words so the explanation fits in a quick conversation, not a lecture.
A diagnostic walkthrough for a specific HVAC error code or symptom — what's likely causing it, what to check first, and step-by-step troubleshooting to get the system running.
I'm an HVAC tech on a service call. [Equipment brand and model] is showing [error code or symptom]. What are the most likely causes and what should I check first? Give me a step-by-step diagnostic sequence.
View full prompt →Tip: Include the equipment brand, model, and model year — accuracy improves significantly with specifics, especially on older equipment. Always verify safety-critical steps against the manufacturer manual before proceeding.
A natural, conversational 60-second script for recommending a maintenance agreement to a homeowner at the end of a service call — without sounding pushy or salesy.
Write a 60-second script for an HVAC technician to recommend a [$X/year] maintenance agreement to a homeowner after completing a service call. Keep it conversational and natural, not salesy. Emphasize: preventing breakdowns, priority scheduling, and cost savings over time.
View full prompt →Tip: Include your actual price and key benefits in the prompt — a generic pitch lands less well than one grounded in specifics. Ask for a version "when the system is older and close to replacement age" if you need a different angle for those situations.
A one-page letter to leave with a homeowner after installing new HVAC equipment — explaining how the system works, how to operate the thermostat, the filter schedule, and what the warranty covers.
Write a one-page homeowner letter for a new [brand model] HVAC system installation. Include: how the system works in plain language, how to operate the [thermostat type], recommended filter change schedule, what the [X]-year parts and [Y]-year labor warranty covers, and who to call for questions.
View full prompt →Tip: Generate this once per equipment type you commonly install, then save it as a template. Add your company name and phone number before printing — it becomes a branded leave-behind that reduces callbacks on basic questions.
A professional message to send a customer when their repair is delayed because a part is on backorder or hasn't arrived yet — honest, apologetic, and reassuring without making excuses.
Write a text message to a customer explaining that the [part name] for their [equipment type] repair is delayed and won't arrive until [date]. Apologize for the inconvenience, explain we're doing everything we can to get it sooner, and confirm the appointment we have scheduled.
View full prompt →Tip: Send this before the customer calls asking for an update — proactive communication is the difference between a patient customer and a frustrated one. Add "offer a $25 service call discount to soften the impact" if your company authorizes that gesture.
A short, professional follow-up text or email to send a customer after a service call — thanking them, summarizing what was done, and letting them know you're available if questions come up.
Draft a follow-up [text message / email] to a homeowner after an HVAC service call. We [brief description of work done, e.g., "replaced the capacitor and ran a system check"]. Keep it friendly, brief, and professional. End with an invitation to reach out with questions.
View full prompt →Tip: Add "include a request for a Google review if they were happy with the service" to get a review ask built into the message — a brief mention in a follow-up converts far better than a separate request days later.
A clear, non-pushy script for telling a customer their aging HVAC system would be better replaced than repaired — framed around their interests, not a sales pitch.
Write a script for an HVAC technician to explain to a homeowner why replacing their [X]-year-old system makes more financial sense than repairing it again. The repair would cost $[amount]. A new system costs $[amount]. Be honest and helpful, not pushy. Help the homeowner make a smart decision.
View full prompt →Tip: Include the actual dollar amounts so the script presents real math, not hypotheticals. Ask for "a version for a price-sensitive customer" or "a version for a repeat customer" — the approach shifts meaningfully depending on who you're talking to.
A professional, empathetic response to a negative online review that acknowledges the customer's frustration, explains your side if appropriate, and invites them to resolve it privately.
Write a professional response to this negative Google review for my HVAC business: "[paste the review text here]". Be empathetic, take accountability where appropriate, and invite them to contact us directly to resolve the issue. Keep it under 100 words.
View full prompt →Tip: Paste the full review text — the AI can reference specific details the customer mentioned, which reads far better than a generic response. If the review contains inaccurate claims, add a note so the AI can tactfully acknowledge that without being defensive.
A professional, customer-facing estimate letter for an HVAC equipment replacement — with a clear price breakdown, warranty details, and a brief explanation of why now is the right time to replace.
Write a professional equipment replacement estimate for a homeowner. Equipment: [brand, model, size]. Total price: $[amount] including labor, materials, and permit. Current system is [X] years old. Warranty: [parts and labor terms]. Include why replacing now makes sense.
View full prompt →Tip: Include the age of the current system and the actual cost numbers — the AI uses those to write a specific "why replace now" argument rather than a generic one. Add "keep it to one page" if you're printing it to leave with the homeowner.
