The AI receptionist that books HVAC calls
while you're on the roof.
HVAC companies miss 30% of inbound calls during installs, service runs, and peak-season surges. APEX AI Receptionist answers every call in under 800ms, qualifies emergencies, books the appointment, and fires a Telegram alert to you — all for $299/mo.
HVAC is a high-stakes phone business. Every missed call is real money.
A no-cool call in July or a no-heat call in January converts at 70%+ if answered within the first two minutes. Miss the call and the customer calls your competitor.
30% of calls go unanswered
Your techs are on roofs, in attics, driving between calls. The phone rings and nobody picks up. Across 11 service businesses we operate in San Diego, missed call rates during peak season run 25–35% — phones ring while techs are on jobs and there is no one to answer.
Emergency calls need instant triage
A flooding drain pan, a tripped high-pressure switch, or a heat exchanger lockout needs a different response than a tune-up booking. Your front desk (if you have one) may not know the difference — the AI is scripted to ask exactly the right qualification questions.
A live answering service costs $1,500+/mo
Third-party HVAC answering services charge $1,200–$2,500 per month for live agents who don't know your scheduling software, can't book directly, and hand you a message instead of a confirmed appointment.
From ring to booked job — in under 3 minutes.
Every APEX deployment is custom-scripted for your HVAC company. Here is the exact flow a caller experiences.
AI answers instantly
Your phone line routes to APEX. The AI answers with your company name and a natural greeting in under 800ms — faster than a human could pick up.
Qualifies the call
The AI asks: name, service address, system type (AC, furnace, heat pump), and the key question — "Is this an emergency, or can we schedule a visit?" It captures all info needed for dispatch.
Books the appointment
For non-emergencies, the AI offers your real available time slots and books the appointment live. Emergency calls trigger an immediate Telegram alert so you can call back in seconds.
Alerts you instantly
The moment a call ends, you receive a Telegram message with the caller name, address, issue summary, scheduled time, and a full call transcript. Nothing falls through the cracks.

Questions HVAC owners ask before buying.
How does an AI receptionist work for HVAC companies?
APEX AI Receptionist is a voice AI agent that answers your business phone line 24/7. When a customer calls, the AI answers in under 800ms with a custom greeting for your HVAC company. It collects the caller's name, address, and issue description, determines whether the call is an emergency (no AC in summer, heating failure in winter) or a standard service request, books the appointment directly into your calendar, and immediately sends you a Telegram alert with the full call summary. You get a transcript of every call.
Can AI book HVAC appointments during the call?
Yes. APEX integrates with Cal.com and your existing scheduling system to offer real available time slots during the call. The customer picks a time, confirms their address and contact info, and the appointment is locked in before they hang up. No callbacks needed. No phone tag. The booking fires a Telegram notification to you or your dispatcher the moment it is confirmed.
How much does an AI answering service cost for an HVAC company?
APEX AI Receptionist costs $500 to set up and $299 per month for unlimited calls. A live answering service for HVAC typically runs $1,000 to $2,500 per month depending on call volume, and the agents rarely know HVAC-specific terminology or can actually book into your scheduling software. APEX handles unlimited call volume, never calls in sick, and costs the same whether you get 20 calls or 2,000 calls in a month.
Will HVAC customers know they are talking to AI?
APEX uses ElevenLabs voice synthesis — the most natural-sounding AI voice available commercially. Per California SB 1001, the AI identifies itself as an automated assistant at the start of the call. Most callers who know what they want — "My AC stopped working, I need someone out today" — move through the call quickly and book without friction. The focus is on getting them what they need fast, which is what callers actually want.
Does APEX integrate with Jobber or Housecall Pro?
APEX integrates natively with Cal.com for appointment booking, and we support webhook-based connections to Jobber, Housecall Pro, and ServiceTitan. During onboarding we configure the integration to push booked jobs directly into your existing field service software so your dispatchers see new jobs appear automatically. If you use a platform not listed, ask us — custom integrations are part of the $500 setup scope.
