❄️ For HVAC contractors

AI voice agents that answer every heatwave call — not just the first forty.

HVAC demand arrives in spikes. The first hot week of summer or cold snap of winter triples your call volume overnight, and a two-person office simply cannot pick up. Our AI voice agent answers unlimited simultaneous calls in about 1.5 seconds, triages no-heat and no-cool emergencies, quotes your diagnostic fee, and books straight into dispatch — so peak week stops being the week you lose the most work.

Peak season is when you lose the most revenue

A 2024 ServiceTitan analysis of more than 50,000 contractor phone lines put the missed-call rate across home services at 62%. Other studies using different methodology land closer to 27%. The honest read is that the real figure sits in that range and depends almost entirely on how you cover overflow and after-hours — but on either number, a meaningful share of your demand never reaches a human.

For HVAC the per-call value is unusually high. Industry estimates put the average after-hours HVAC call at roughly $1,400, the average missed call at $350 or more in lost revenue, and annual losses from missed calls at around $45,600 per contractor. After-hours accounts for an estimated 35–45% of inbound volume, with traditional pickup rates under 18%.

The seasonal shape makes it worse. When a heatwave hits, every competitor is equally swamped — so the homeowner books whoever answers. Capacity to answer becomes the differentiator, well before capacity to attend does.

Built for how HVAC calls actually work

01

No-heat / no-cool triage

Separates a genuine no-heat call in January from a routine maintenance enquiry in the first fifteen seconds, and escalates emergencies to your on-call tech immediately.

02

Unlimited simultaneous calls

Peak-season spikes stop being a capacity problem. Forty callers at 8am on the first hot day all get answered at once instead of forty-one going to voicemail.

03

Diagnostic fee quoted up front

Your call-out or diagnostic charge is stated on the call, filtering out price-shoppers before you dispatch a van across town.

04

Maintenance plan capture

Recognises existing service-plan members, prioritises them appropriately, and offers plan enrolment to new callers at the point they are most receptive.

05

Equipment details captured

Collects make, model, age and symptom before the truck rolls, so your tech arrives with the right parts instead of making a second trip.

06

Every call transcribed and scored

Full transcripts and weekly reporting on what callers actually asked for — including how many were replacements rather than repairs, which is the number that shapes your quarter.

Live before your next peak

Week 0

Discovery + scope

30-min call to map your setup: seasonal call pattern, dispatch software, on-call rotation, service-plan structure and your top ten caller scenarios.

Free, no pitch
Week 1

Build + voice tuning

We write your greeting, triage logic, fee script and plan-member handling, then tune the voice until it sounds like your best CSR rather than a robot.

Week 2

Integration + test calls

Connected to ServiceTitan, Housecall Pro or your scheduler. You and your team place real test calls until the edge cases behave.

Week 3

Go live + tune

Starts on after-hours and overflow, then expands into daytime as you get comfortable. We review transcripts weekly for the first month.

Priced against a single recovered call

At an estimated $1,400 for the average after-hours HVAC call, the entry plan pays for itself if it saves you one call a month. Setup, integration and ongoing tuning are included — there is no separate onboarding fee.

Frequently asked questions

Can it handle peak-season call volume?
Yes — this is the main reason HVAC contractors buy it. The agent answers unlimited simultaneous calls, so the first hot morning of summer is handled the same way a quiet Tuesday is. There is no queue and no engaged tone.
How does it treat existing service-plan members?
It recognises them from the phone number or by asking, then applies whatever priority rules you set — earlier slots, waived diagnostic fee, or direct escalation. New callers get offered plan enrolment at the point in the call where uptake is highest.
What happens on a genuine no-heat emergency?
Emergency intents are detected within the first few seconds and escalated straight away — warm transfer to the on-call tech, or SMS and call blast to the rotation, depending on your configuration. The agent stays with the customer while that happens.
Does it integrate with ServiceTitan?
Yes. ServiceTitan, Housecall Pro, Jobber and most mainstream dispatch platforms connect directly, and anything with an API can be integrated. Jobs arrive with equipment details, symptom and access notes already captured.
Will it try to diagnose the fault?
No, and deliberately so. It captures make, model, age and symptom so your tech arrives prepared, but it does not attempt a diagnosis or quote a repair price over the phone. That stays with your people, where it belongs.
What is the realistic payback period?
At roughly $1,400 per after-hours call and $350 as the estimated average value of any missed call, the entry plan needs to recover about one call a month to break even. Most contractors can see the answer in the first month of transcripts, since the volume of previously-missed after-hours calls is usually higher than expected.

Why HVAC call handling breaks differently

HVAC has a demand shape that no amount of staffing solves cleanly. Most of the year the phone is manageable; then the first freeze or the first heatwave arrives and a single day produces several times normal call volume. Hiring for the peak is uneconomic and hiring for the average means losing the peak, which is exactly when the highest-ticket work is available.

That is the core argument for an agent here, and it differs from the argument in other trades. It is not primarily about after-hours cover, though that matters too. It is about concurrency on the handful of days each year that disproportionately determine your season.

Three configuration decisions do most of the work. First, a severity branch separating no heat, no cool and routine maintenance, because in January those are not the same call. Second, service-area qualification by postcode before any slot is offered, since a booked job outside your radius costs more than a missed call. Third, a distinct path for replacement and estimate enquiries, which are long, consultative and worth far more than a diagnostic visit.

AI voice agents for HVAC companies: common questions

What does an AI voice agent do for an HVAC company?

It answers every call around the clock, separates a no-heat or no-cool emergency from a routine service or estimate enquiry, checks the caller is inside your service area before offering a slot, and books the job into your field-service software with the problem description attached. It also absorbs the seasonal surge, holding as many simultaneous calls as arrive during the first cold snap rather than queueing them.

How does it handle the seasonal HVAC rush?

This is where it earns its keep. HVAC demand is spiky: the first freeze or first heatwave produces a day of call volume several times normal, and a human dispatcher can hold one call at a time. An AI agent holds unlimited simultaneous calls, so nobody hears a busy tone on the day when every competitor is also overwhelmed. It also triages, so genuine no-heat calls get emergency slots while tune-up enquiries get booked into normal capacity.

Can it book into ServiceTitan, Housecall Pro or FieldEdge?

Yes, and this is the question worth pressing any vendor on. Real integration writes the job, customer record, service address and problem description into the system your techs already work from. If a tool only creates a calendar entry that your dispatcher re-keys, it has automated the ringing rather than the work, which is a much smaller benefit than the pricing implies.

Will it handle replacement and estimate enquiries properly?

A meaningful share of HVAC revenue comes from system replacement, where the call is a long consultative conversation rather than a booking. A well-configured agent captures system age, fuel source, property type and rough square footage, then routes a qualified estimate lead to a comfort advisor instead of dropping a twenty-minute diagnostic on the technician board. Getting this branch right matters more for HVAC than for most trades.

How much does it cost for an HVAC business?

Typically a flat monthly fee scaled to call volume and number of trucks rather than per call, plus a one-off setup fee covering call-flow design, integration and testing. Compare it against the value of jobs currently reaching voicemail, particularly during seasonal peaks and after hours, when a single recovered no-heat call often carries a higher ticket than a week of routine work.
