HVAC CRM, multiplied.
Software that works your service history, calls the builders and property managers who send you work and books the visit.
Multiply Revenue is sales software for HVAC companies. It works the customer list you already have, systems past replacement age, maintenance agreements about to lapse, tune-ups due before the season, then an AI agent calls them and books the visit onto your board. It calls the builders and property managers who hand out HVAC work.
It answers every inbound call and web lead the moment it arrives and follows up until it is booked. Every call is scored, so you find out which of your people keeps quoting a repair on a system that needed replacing. Calls, texts and emails all sit in one place, so the shoulder months between the heat and the freeze stop being the quiet ones.
No setup fee on any plan, and no per-text charge from us.
What HVAC businesses fight every day.
Paying for Leads Shared With Competing Contractors
You buy leads from HomeAdvisor, Angi or Thumbtack. By the time you call, other contractors already have. The AI calls the moment the lead lands and keeps calling until they answer, and it works the customers you already have, whose systems you know the age of, which no lead vendor can sell to anyone.
After-Hours Emergencies Go Unanswered
AC breaks at 9 PM on a 100-degree day. Homeowner calls 5 HVAC contractors. The first one to answer gets the emergency call. An AI phone system answers every call immediately, qualifying urgency, routing emergency calls and booking non-urgent appointments automatically.
Maintenance Agreements Lapse Because Nobody Makes the Renewal Call
You sold a maintenance plan eleven months ago. Renewal comes round, nobody calls, and the customer forgets they had one. That is recurring revenue you had already earned, lost every year to the absence of a reminder rather than to a competitor.
A Heat Wave Turns a Week of Calls Into an Afternoon of Them
A heat wave hits and enquiries jump several times over inside a day. Every one of those homeowners is calling three contractors, not one, and whoever gets back first takes the job. The agent holds every conversation at once, triages the urgent ones and fills the schedule without you hiring for a fortnight of weather.
In peak season most enquiries reach a contractor who is already out on a job. The one who answers takes the work.
A repair or a replacement is a substantial job, and a single slow week during a heat wave is several of them going elsewhere.
Homeowners with a dead system call several contractors and hire whoever picks up, not whoever has the best reviews.
AI built for HVAC businesses.
Answers Every Call 24/7 Including After-Hours Emergencies
AC breaks at 11 PM on a 98-degree night. The homeowner contacts 5 contractors. Your AI responds immediately, assesses urgency, qualifies the issue and either dispatches your on-call tech or books first-available service. The other four get back to them in the morning. You booked the job.
Books Service Appointments Directly Into Your Dispatch System
AI doesn't just take messages, it books appointments. Homeowner selects a time slot based on your real-time availability, gets a confirmation text and shows up as a booked job in ServiceTitan or Housecall Pro. No manual entry, no double-bookings, no missed follow-up.
Handles Seasonal Surge Without Adding Staff
When a heat wave hits and demand jumps several times over, AI handles every conversation at once. While competitors work through a backlog, your AI is triaging urgency, qualifying emergencies and filling your schedule without hiring temporary office staff.
What it costs you today, and what changes.
Enquiries Wait While HVAC Technicians Are on the Job
Your HVAC technicians are under sinks, on rooftops and inside crawl spaces all day. Every hour an enquiry waits in peak season is a homeowner with broken HVAC who has already hired your competitor. AI agents handle every conversation at once so your contractors stay productive on jobs.
The Season's Best Week Is the Week You Cannot Answer the Phone
When temperatures hit extremes, demand jumps several times over inside two days and your office cannot keep up. Enquiries queue, go stale and end up with a contractor who could answer. The work you lose in that week is the highest-margin work of the year.
A Homeowner With No Heat Hires Whoever Picks Up
HVAC is a speed business. Somebody whose system has failed is not reading your reviews, they are working down a list of four contractors and hiring the first one who answers. Everything else you spend on winning that customer only counts if you are the one who picks up.
The Systems You Installed Are Ageing Without a Call From You
Every unit you put in has a service date and an end of life, and both are sitting in your records. The replacement usually goes to whoever the homeowner rings the day it fails, which is rarely the company that installed it. Working your own install list on a schedule is the cheapest job you will ever book.
Call General Contractors for Subcontract Work
GCs referral sourceVoice AI calls general contractors, home builders and renovation companies in your area daily. Every new build, addition and gut renovation needs HVAC. AI positions your company as their preferred subcontractor and books meetings to discuss project pipelines.
Call Property Managers for Maintenance Contracts
PMs recurring revenueAI contacts property management companies managing apartment complexes, office buildings and retail spaces. These managers need reliable HVAC service year round. AI pitches your maintenance contract program and books walk-throughs for multi-unit deals.
Call the Systems You Installed
Replacements high valueYou installed those systems, so you know exactly how old they are, which is better information than any list you could buy. The agent works your service history: the units past replacement age, the repairs you have been back to twice, the maintenance agreements about to lapse. It offers the assessment while the homeowner is comfortable rather than standing in a hot house.
Call Past Customers for Seasonal Tune-Ups
Retention growth engineAI calls your customer list before summer and winter seasons to schedule maintenance appointments. Also requests Google reviews, asks for neighbor referrals and identifies systems approaching replacement age. Keeps your schedule full during slow periods.
How HVAC teams put it to work.
24/7 Emergency Call Capture
AC breaks at 11 PM on a 98-degree night. AI responds immediately, assesses urgency and dispatches your on-call tech for true emergencies or books next-day service for routine repairs. The after-hours emergency stays yours instead of going to whoever answers first.
Seasonal Surge Management Without Hiring
When a heat wave hits and demand jumps several times over, AI handles every conversation at once. Triages urgency, qualifies emergencies and books the work while competitors are still working through their backlog.
Maintenance Agreement Renewals
AI monitors contract expiration dates, calls customers 30 days before renewal, explains benefits of continuing coverage and books renewal appointments. Recovers recurring revenue that walks out the door when renewals go uncontacted.
Pre-Season Tune-Up Campaigns
Before summer and winter, AI proactively contacts your customer list to schedule preventive maintenance appointments. Homeowners who maintain their systems spend more on eventual replacements and call you first when systems fail.

HVAC teams always ask.
How do AI agents for HVAC handle true emergency calls?+
The AI agent asks diagnostic questions, including no heat in freezing weather, no AC with elderly or infants in the home or gas smell. Genuine emergencies trigger immediate dispatch to your on-call HVAC technicians. Non-urgent HVAC services get booked into the next available slot automatically.
Can AI agents for HVAC provide rough estimates on common HVAC services?+
The AI agent can give ballpark ranges for common HVAC services based on your pricing structure, making clear that final pricing requires an on-site assessment from your HVAC technicians. This builds trust early while protecting your sales team from price-shoppers who never intended to book.
Do AI agents for HVAC integrate with my dispatch and scheduling software?+
We integrate with ServiceTitan, Housecall Pro and other major HVAC software to create jobs and schedule appointments directly. Your HVAC business runs the same workflow. AI agents just handle the inbound call and automate the booking.
How does the software produce service calls and replacement leads?+
Two ways. It works your own service history: the systems you installed that are near the end of their life get a call offering a maintenance check, which often turns into a replacement conversation. And it answers every inbound call and web lead right away, books the visit and keeps following up on anyone who did not pick up, all while your techs stay on the job they are on.
Does the software replace the marketing my HVAC company already does?+
No, it sits on top of it. Your website, your listings and your referrals keep producing inquiries and the software makes sure each one gets a real conversation within seconds instead of a voicemail. What it adds is the outbound side: a steady set of conversations with homeowners who will need a system soon, which is a pipeline that does not depend on the weather.
How quickly can an HVAC company see results?+
Inbound answering starts working the day it is switched on, because it is handling calls you were already getting. Outbound calls to your own customer list begin the same week. The first booked visits come from the first people who answer, so how fast the schedule fills depends on how many customers in your records are due a renewal, a tune-up or a system.
What should HVAC CRM software include?+
Look for one customer record that keeps the full service history, including every call, text and email, plus a way to follow up on estimates until they close, reminders for maintenance agreements and tune-ups, booking and reporting on where your jobs come from.
Multiply Revenue gives you that record, an AI agent that works the follow-up and the old estimates that never closed, appointment booking, call recording and scoring, and analytics that show which leads turned into deals. You can also create an invoice from the customer record and download it as a PDF with tax added. It is sales software, so check how it fits with the dispatch and accounting tools your HVAC business already uses.
How is HVAC CRM software different from field service management software?+
Field service software such as ServiceTitan, Housecall Pro or Jobber is built around scheduling, dispatching and invoicing the work you have already sold. HVAC CRM software is built around winning that work in the first place: answering and calling leads, working your service history and following up on estimates and renewals. Many HVAC companies use both, so the real test is whether a booked job lands in the system your technicians already open each morning.
