Where HVAC calls slip through today

Heat waves and cold snaps drown your phones

HVAC demand isn't steady — it spikes. The first 95-degree afternoon or the first hard freeze compresses a week of revenue into 48 hours, and that's exactly when every line is busy and calls roll to voicemail. The AI answers all of them at once, so a demand spike fills your schedule instead of your competitor's.

After-hours no-heat and no-cool calls go to voicemail

Emergency tickets carry a real premium, but an answering machine at 9 p.m. doesn't close them. As CallerWho's HVAC after-hours analysis lays out, the calls that hit voicemail at night and on weekends are disproportionately your highest-value emergency jobs — the ones your competitor books on the second ring. The AI answers every one of them, day or night.

Every caller gets treated the same

A $25 filter question and a full-system replacement on a $1.4M two-zone home ring the same phone and get the same hurried answer. Without knowing who's calling, your team can't prioritize the install that's worth ten repairs — or stop waking the on-call tech for a thermostat reset.

Generic answering services don't speak HVAC

A call-center script can take a name and number, but it can't tell a refrigerant leak from a clogged condensate line, can't recognize "smell of gas" as an escalate-now signal, and can't tell whether a caller can actually authorize a $14k system swap. You get a message, not a booked job.

Caller intelligence, applied to HVAC

Before the first hello, CallerWho checks the caller against public property records and licensed data providers — 150+ signals, shown only to your business and never sold, rented or shared — and puts them on your ring card and into your routing rules. Here is what that looks like on a HVAC call. See all 150+ signals →

Central air on record: None on record: a no-cool call may really be a new-system install — ask what cools the house now. On record in a 2010 house: the original system is about 16 years old, past the usual 15 to 20, so quote the replacement next to the repair.
Stories: Two stories and upstairs runs hot: pitch a second zone or a second system, and ask which floor the problem is on before you roll.
Year built: Before 1980, duct wrap and old furnace insulation can contain asbestos — check before you cut. An older house is where duct replacement and a new system sell together.
Owner or renter — who says yes: A renter can’t sign off on a system replacement or a maintenance plan; the card names the landlord. An owner who lives there can say yes today — lead with the replacement and the plan.
Estimated home value: Separates the filter swap from the full-system replacement before you pick up, and a home-value rule can ring your on-call tech first for the high-value no-cool call.
Fireplace: A gas line or chimney on site: check the carbon monoxide detectors and the venting while you’re there — an easy add-on visit.
New owner: Bought this year: offer a full system check and a maintenance plan before their first summer.

Not a generic answering service

It knows who's calling before it answers. Generic AI answering services just pick up. CallerWho checks the caller against public property records and licensed data providers and surfaces 150+ signals like owner-vs-renter, home value, and service-zone fit in real time — shown only to your business, never sold, rented or shared. The details go on your ring card and into your routing rules, and they're never recited back to the caller. Every lookup is logged in your dashboard, and you can turn lookups off whenever you want.
Built for HVAC economics, not generic call-taking. The AI is configured to recognize HVAC emergency keywords — no cool, no heat, smell of gas, water leaking from the unit, system shut off on its own — and combine them with caller intelligence to wake the on-call tech only for jobs worth the trip. High-value premium installs go to your closer; low-urgency filter and thermostat questions drop into a morning queue. You stop treating every caller the same.
Intelligence-only mode keeps your team in the loop. Don't want the AI on the line? Flip it off and your own team still answers — with the full caller profile on screen as the phone rings. Use the AI after-hours, on weekends, and for overflow, and run your people on the daytime rush. It schedules around how you already work, with no PBX changes and no developer.

One plan. No surprises.

$49/month per phone line — Voice AI Agent service with unlimited AI talk time on every line. Your main line and every line you add are the same $49. New local U.S. number or port your own.
Or $490/year per line, paid up front — 2 months free on every line: it works out to $40.83/month and saves $98 per line each year. Extra lines are $490/year too.
Plus $2 per new caller, billed monthly on either plan — a number that has never reached you before, charged once, the first time they reach you on a call that connects for 20 seconds or more. Every call after that from the same number is free.
Never charged — repeat callers, spam, robocalls and telemarketing calls, wrong numbers, blocked numbers, and hang-ups under 20 seconds.

Example: 20 new callers in a month on one line = $49 + $40 = $89 on the monthly plan, or just the $40 that month on the annual plan. No setup fee. Monthly: no contracts, cancel anytime. Annual: paid up front for the year, not refunded. See full pricing and the ROI math →

HVAC AI voice agent — FAQ

Can the AI handle after-hours no-heat and no-cool emergencies?

Yes. The AI answers 24/7 and is configured to recognize HVAC emergency conditions — no cool, no heat, smell of gas, water leaking from the unit, a system that shut off on its own. It screens for urgency, combines that with caller intelligence like home value and service-zone fit, and routes genuine premium emergencies to your on-call tech while lower-urgency calls go to a morning callback queue.

How does it decide which calls are worth waking the on-call tech?

It weighs the emergency signals against the caller's profile — owner vs renter, estimated home value, and distance to the job. A no-cool call from a high-value, in-zone homeowner who can authorize the work routes straight to your tech; a renter's noisy-unit question or a thermostat reset does not. You set the escalation rules; the AI applies them on every call.

Will the AI tell callers it knows their home value?

No. The caller details go on your ring card and into your routing rules — they are never recited back to the caller. The data comes from public property records and licensed data providers, not from the calls themselves, and it is shown only to your business — never sold, rented or shared. Every lookup is logged in your dashboard, and you can switch them off anytime.

What does it cost for an HVAC company?

$49/month per phone line for the Voice AI Agent service — port your existing number or get a new local one — with unlimited AI talk time and no per-minute charges, plus $2 per new caller: a phone number that has never reached you before, charged once, the first time it reaches you on a call that connects for 20 seconds or more. Repeat callers, spam and robocalls, wrong numbers, blocked numbers, and hang-ups under 20 seconds are never charged. Every line is the same $49/month. Or prepay a year: $490/year per line, paid up front — 2 months free on every line (it works out to $40.83/month and saves $98 per line). New callers are billed monthly on either plan. Example: 20 new callers in a month on one line is $49 + $40 = $89. No PBX changes. Monthly has no contract and you can cancel anytime; the annual prepayment covers the year and is not refunded.

Do I have to replace my phone system or hire a developer?

No. There are no PBX changes and no developer required. It works on a web softphone or a VoIP hardphone (Poly/Polycom, Yealink, Cisco), and the AI is optional and schedulable — run it after-hours, on weekends, or for overflow only and keep your team on the daytime rush. You can be live in a few minutes.
