AI RECEPTIONIST · HVAC

The AI receptionist that actually books HVAC service calls.

Heat waves spike your call volume 3× overnight. Your dispatcher was built for a normal Tuesday. InstaNexus picks up every call — even at 4:47 PM on day 3 of a 105° dome — qualifies the job against your service menu, and books it straight into your calendar.

What InstaNexus does for hvac shops.

01

Picks up in 1–2 rings, 24/7

Every call — including the 4:47 PM heat-dome surge — gets answered live. No voicemail, no "all agents busy."

02

Qualifies the job in 30 seconds

Asks zip code, system age, brand, and urgency against your service menu — then routes emergencies, schedulables, and maintenance differently.

03

Books directly into your calendar

Drops appointments straight into Google Calendar or Outlook with the right time window for the job type. Texts the homeowner a confirmation.

04

Trained on your service menu

Your pricing, service area, brands you service, emergency policy — all wired in under an hour. Calls sound like you, not a generic robot.

How it handles a hvac call.

Three real scenarios your shop sees every week — and exactly how the AI receptionist runs each one, start to finish.

The 4:47 PM no-cool call on day 3 of a 105° dome

A homeowner's 12-year-old Carrier condenser quit an hour ago. Inside temp is 94°. She has a toddler and a dog in the house.

Caller
Hi — my AC just died and it's unbearable in here. I have a baby, I need someone out today.
AI
I'm sorry you're dealing with that in this heat — let me get a tech to you fast. Can I grab your zip code and the brand on the outside unit?
Caller
85282. It's a Carrier, probably 12 years old.
AI
Got it — Tempe, you're inside our service area. Is the outdoor unit totally silent, or is it running but not cooling?
Caller
Totally silent. I already checked the breaker.
AI
That sounds like a same-day emergency. I'm flagging our on-call tech right now and booking you a 6–8 PM window tonight. What's the best cell to text a confirmation and the tech's ETA?
Caller
602-555-0144.
AI
Perfect — you're booked. The tech's name and a live ETA will hit your phone within ten minutes.
Outcome Emergency routed to on-call tech in under 90 seconds; job dropped onto the shop calendar with Carrier, 12-yr age, and silent-outdoor-unit symptom already in the notes.

The pre-season tune-up scheduler

A repeat customer calls in late March wanting his spring AC checkup before the desert season hits.

Caller
Hey, I'm due for my spring tune-up. Johnson, I think you came out last fall for the heat side.
AI
Thanks for calling back — let me pull you up. Can I confirm the address on file so I grab the right system?
Caller
4418 East Palm Lane, Phoenix.
AI
Found you — Lennox split system, installed 2019. Our spring AC tune-up runs about an hour, and I'll text the price from your shop menu with the confirmation. I have Thursday the 7th at 10 AM or Friday the 8th at 2 PM. Which works?
Caller
Thursday the 7th, 10 AM.
AI
Booked. You'll get a text confirmation and a reminder the morning of. Anything running weird on the system I should note for the tech?
Caller
No, it was fine all winter.
AI
Perfect — I'll just flag it as a standard spring PM. See you Thursday.
Outcome Tune-up dropped onto the shop calendar with the customer's existing equipment record pre-attached — dispatcher never touched it.

The 18-year-old unit — repair or replace?

A homeowner's Trane heat pump is making a loud hum and shutting off. He wants to know if it's worth fixing.

View transcript
Caller
My Trane is making this awful hum and cycling off. It's old though — I'm wondering if I should just replace it.
AI
Good question to ask before you sink money into a diagnostic. How old is the unit, and do you know if it's under any warranty?
Caller
It was here when I bought the place — I think 2007? No warranty I know of.
AI
At 18 years, you're past the typical 12–15 year service life and definitely out of factory warranty. I can send a tech out to diagnose it and walk you through repair cost versus replacement options — the diagnostic fee is on your shop menu and there's no pressure to do either on the spot.
Caller
Okay, let's do that. Tomorrow if possible.
AI
Can you give me the zip and a good cell? I've got a tomorrow 1–3 PM window open.
Caller
85044, and 480-555-0193.
AI
Locked in. Tech will bring replacement pricing for a same-capacity Trane and a high-SEER option so you can decide with real numbers in hand.
Outcome Diagnostic booked with full context: 18-yr Trane, hum + short-cycle, customer open to replacement quote — tech walks in ready to sell a system, not just swap a capacitor.

Works with the tools your hvac shop already runs.

Books straight into the calendar your HVAC shop already runs on — no new numbers, no port-outs, no learning curve to pick up when a heat wave hits. Custom integrations with ServiceTitan, Housecall Pro, or FieldEdge can be scoped during onboarding for shops that need them.

Answers to the questions hvac shops ask most.

Does InstaNexus work with ServiceTitan or Housecall Pro?
Out of the box, the AI books directly into Google Calendar, Outlook, Microsoft 365, or iCal — whichever calendar your shop already runs dispatch on. Custom integrations with ServiceTitan, Housecall Pro, or FieldEdge can be scoped during onboarding if you need booked jobs to land on a work order with zip, system age, brand, and symptom pre-populated. We'll walk through what that looks like on the demo call.
What happens if five heat-wave emergencies come in at the same time?
The AI answers every line in parallel — there's no hold queue. It triages each caller in under 30 seconds, and anything flagged as a same-day emergency gets routed to your on-call tech with a live notification. Schedulable jobs and tune-ups get booked into the calendar without ever touching dispatch.
How long does it take to set up for an HVAC shop?
About an hour of your time on the phone, and you're live in under a week. We train the AI on your service menu, pricing, brands, service area, and emergency policy during onboarding. Quotes depend on monthly call volume, after-hours handling, and any custom CRM or dispatch integrations — we scope it on the demo call.
Can the AI recognize one of our regulars and pull up their equipment history?
Yes, if the caller ID matches a record in your CRM. The AI greets them by name, pulls the last service address and installed equipment, and skips the basic qualifying questions — so a tune-up call from a returning customer takes about 45 seconds.
What if the caller just wants to talk to a human?
It transfers. If a caller asks for a person, sounds confused, or the call is outside what the AI was trained on, it hands off to whoever you designate — your dispatcher during business hours, your on-call tech after hours, or a voicemail-to-text fallback you review in the morning.
Will it handle after-hours and weekend calls differently from business hours?
Yes. You set the rules during onboarding: which job types count as emergencies after 6 PM, whether after-hours dispatch carries a trip-charge surcharge, and which tech is on-call each night. The AI follows the same dispatch playbook you'd give a new CSR on day one.
Does it work for shops that service both residential and light commercial?
Yes. The AI asks early whether the caller is residential or commercial and branches the qualifying script accordingly — rooftop unit versus split system, property-manager billing versus homeowner, after-hours commercial contract versus retail rates. Both paths route to the right tech and the right pricing.
