HVAC shops write a lot between calls: appointment texts, estimate follow-ups, review replies, tune-up promos and notes for the next tech. The free ChatGPT tier handles most of it with good prompts. Copy these, fill in the brackets, and always read the output before you send it.

Tip: start each chat with a short "about my business" note (services, brands you install, service area, tone, membership plan details). Do not paste customer phone numbers, addresses, lockbox codes or payment details.

1. Customer texts

On my way: "Write a short, friendly text from a tech named [name] saying they are about 20 minutes out for an HVAC service call. Under 30 words."
Appointment reminder: "Write a reminder text for a [service, e.g. AC tune-up] tomorrow between [window]. Ask them to clear access to the indoor unit and filter, and reply C to confirm."
No-cool / no-heat triage: "Write a short text to send a customer who reports no cooling while they wait for us. Include three safe things to check (thermostat mode and batteries, breaker, dirty filter) and tell them not to open panels."
Running late: "Write an apologetic text saying our tech is running about [X] minutes late because the previous call ran long, and offer to reschedule if needed."

2. Estimates and follow-ups

Notes to estimate: "Turn these tech notes into a clear replacement estimate summary for a homeowner: [notes]. Explain the problem in plain English, list options, what is included, warranty, and that the quote is valid for 30 days. Under 250 words."
Good / better / best: "Create three system replacement options using these units and prices: [details]. Explain efficiency, comfort and warranty differences without jargon."
Repair vs replace: "Write a short, honest explanation for a customer with a [age]-year-old system and a $[price] repair, comparing repair versus replacement. No scare tactics."
Estimate follow-up: "Write a two-sentence text following up on a [job] estimate I sent [X] days ago. Friendly, no pressure, offer to answer questions or walk through financing."
Last follow-up: "Write a final follow-up email for an unanswered replacement quote. Mention install slots before [season] are filling up and offer to hold one until [date]."

If you send estimates often, put them in Housecall Pro, Jobber or ServiceTitan so customers can approve online, and use ChatGPT to tighten the wording.

3. Google review replies

Positive review: "Reply to this 5-star Google review for my HVAC company: [review]. Thank them by first name, mention the tech and the work, under 50 words, no emojis."
Negative review: "Reply to this negative review: [review]. Stay calm, acknowledge the issue, do not share account details or argue, and invite them to call our office manager. Under 80 words."
Review request: "Write a short text asking a customer for a Google review after [tech] fixed their [issue] today. Include a link placeholder, under 40 words."

To send review requests automatically after every job, look at NiceJob, Podium or Birdeye.

4. Seasonal campaigns

Season calendar: "Make a 12-month marketing calendar for an HVAC company in [region]. For each month, list what to promote (AC tune-ups, furnace checks, IAQ, maintenance plans, rebates) and one post idea."
Tune-up email: "Write a short email to past customers announcing [spring AC / fall furnace] tune-ups for $[price], with a booking link placeholder and a deadline of [date]."
Maintenance plan pitch: "Write a plain-English explanation of our maintenance plan: [benefits and price]. Under 120 words, for a postcard and a text version."
Heat wave / cold snap: "Write a Facebook post for an upcoming [heat wave / cold snap] with three tips to protect the system and a note that we offer [service]."

Drop the copy into Canva for postcards and posts, and send emails with Mailchimp.

5. Dispatch and tech notes

Clean up job notes: "Rewrite these rough tech notes into clear job notes for the customer record: [notes]. Sections: complaint, findings, work done, parts used, recommendations, follow-up needed."
Dispatch summary: "Turn these call notes into a dispatch note for the tech: [notes]. Include issue, equipment info if known, access notes placeholder, priority, and what to bring."
Callback handoff: "Write a handoff note for a second tech going back to a callback job, based on: [first visit notes]. List what was tried and what to check next."
Translate: "Translate these install instructions into Spanish in simple, clear language: [instructions]."

6. Website and Google listing

"Write a 300-word service page for [service, e.g. heat pump installation] in [town], with a short FAQ. Only use these facts: [facts]."
"Write a Google Business Profile description for my HVAC company under 750 characters. Services: [list]. Areas: [towns]."

Before you rely on AI writing

Check every price, rebate, efficiency rating and warranty term before it goes out. AI will invent details.
Never let AI give safety advice beyond basic checks; gas smells and electrical issues go to a pro or the utility.
