How does an HVAC company use an AI agent to book more jobs?
An HVAC company uses an AI agent to answer no-cool and no-heat calls around the clock, triage them by urgency, book the right technician, and then sell and renew maintenance plans in the slow months. Automated review requests after each visit keep the Google rating fresh through both peak seasons.
HVAC runs on two spikes. The first real heat wave and the first hard cold snap each bury the phones for a week or two, and the shoulder months in between go quiet. According to the U.S. Energy Information Administration, 88% of U.S. households use air conditioning, and two-thirds use central AC or a heat pump as their main system. When those systems fail on a 98 degree afternoon, the homeowner books whoever answers first.
What should an HVAC AI agent ask a caller?
An HVAC AI agent should ask what the system is doing, what type of system it is, and whether anyone in the home is at risk from the heat or cold. Those answers decide whether it's a same-day emergency, a next-day repair or a replacement estimate, and which technician to send.
Opening line: "Thanks for calling [Company]. Is your system not cooling, not heating, or are you calling about maintenance or a new system?" Then:
- What's it doing? (Blowing warm air, not turning on, leaking water, ice on the lines, a new noise, a burning smell.)
- Is it central air, a heat pump, a furnace, a boiler or a mini-split?
- Roughly how old is the system, and do you know the brand?
- Is anyone in the home elderly, an infant, or someone the temperature affects medically? (The agent only needs yes or no, to flag priority. It doesn't ask for details.)
- Are you on one of our maintenance plans? (Members get priority slots.)
- Is the equipment in an attic, crawl space or closet, and is there a gate code or pet we should know about?
Two scripted safety rules. If the caller mentions a gas smell, the agent tells them to leave the house and call the gas utility or 911, then alerts your on-call tech. And the agent states your diagnostic or trip fee before booking, so nobody's surprised at the door.
When should an HVAC company send a review request?
Send an HVAC review request about two hours after a repair, once the house has started cooling or heating again, and 24 to 48 hours after a new system install, once the homeowner has felt it run through a full day. For maintenance plan members, ask once a year instead of after every tune-up.
Responding matters too. The BrightLocal Local Consumer Review Survey 2026 found 89% of consumers expect owners to respond to reviews, and 68% will only use a business with four stars or more.
| Visit type | Send the request | Why this timing |
|---|---|---|
| Emergency repair | About 2 hours after the tech leaves | The house is comfortable again and relief is fresh |
| New system install | 24 to 48 hours later | They've felt it run and seen the thermostat hold |
| Maintenance tune-up | Once a year, after the spring visit | Asking every visit wears members out |
| Duct cleaning or IAQ | Next morning | Results aren't instant, so give it a night |
| Diagnosis only, declined repair | Don't ask | Move them into follow-up instead |
Ask every customer in each category, good visit or bad. Google prohibits selectively soliciting positive reviews and offering discounts for reviews (Google contribution policy). The AI-suggested reply feature drafts a response to each review that your office can edit and post the same day. More on that in how to get Google reviews on autopilot.
How do you follow up on an HVAC replacement quote?
Follow up on an HVAC replacement quote within 24 hours, because a homeowner with a dead system decides in days, not weeks. Send the quote by text, have the agent answer financing and efficiency questions on day 1, and call on day 2. If the old unit is still limping along, shift to a longer, slower sequence.
Replacement is the big ticket. A new system averages about $7,500, with most homeowners paying between $5,000 and $12,500, according to HomeAdvisor's 2026 cost data. The common objections are predictable, so script them:
- "I'll just fix it this time." The agent books a call with your comfort advisor to compare repair cost against system age. It doesn't argue.
- "That's more than I expected." It sends your financing options and asks if a monthly number would help.
- "I'm getting other quotes." It asks which matters most (warranty, efficiency, install date) and logs the answer for the advisor.
- "I'll wait until it dies." It moves them into a nurture with a pre-season check before summer and winter.
Sequence: day 0 quote text, day 1 questions text, day 2 voice call, day 5 check-in, day 14 "should we keep this quote open?" If the system is fully down, compress all of that into 72 hours.
How do you sell and renew HVAC maintenance plans with automation?
Sell maintenance plans by having the AI agent offer one at the end of every repair booking, then renew them with a reminder 30 days before expiration and a booking text for each pre-season tune-up. Spring cooling checks and fall heating checks fill the shoulder months when the phones go quiet.
HVAC maintenance runs about $250 a visit on average, with a range of $100 to $650 depending on system and season, per Angi's 2026 cost guide. A plan that bundles two visits gives you a reason to text members twice a year and keeps them from calling a competitor when something breaks.
Campaign timing I'd use: cooling tune-up texts go out in March and April, heating tune-ups in September and October. The agent books members first, then non-members who had a repair in the last 18 months.
What pipeline stages should an HVAC CRM have?
An HVAC CRM should run two pipelines: service (new call, booked, dispatched, completed, invoiced, review requested) and replacement (estimate booked, estimate given, follow-up, financing, sold, installed, review requested). Keeping them separate stops a $7,500 install from getting lost in a list of $200 service calls.
Add a third, smaller pipeline for maintenance members with stages for active, renewal due, renewed and lapsed. Lapsed members get a win-back text before the next peak season. If you want the automations for each stage, I listed mine in CRM automations every local business needs.
Do HVAC companies need consent for AI calls and texts?
Yes for outbound. The FCC ruled in February 2024 that AI-generated voices are "artificial" voices under the TCPA, so calling someone with an AI voice needs their prior express consent. Inbound calls are fine, and callbacks to people who asked to be contacted are the safe starting point.
That matters most for tune-up campaigns. Calling your past customer list with a voice agent is different from answering the phone. Make sure your booking forms and invoices collect consent for calls and texts, and keep an opt-out on every message. Details are in the FCC's announcement.
Where KenjiAI fits
KenjiAI gives an HVAC shop the voice agent for peak-season calls, the SMS agent for after-hours texts, separate service and replacement pipelines, calendar booking with reminders, and review requests that fire when a job closes. It's one login and a mobile app your techs can use. You can hear how the voice agents handle a no-cool call before you commit.
What should you set up first?
Set up the emergency triage questions and the 2-hour post-repair review request first. Those two pay off in the first heat wave. Then book a call with us and we'll build the replacement follow-up and maintenance renewal sequences before your next shoulder season.
