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.
Every call — including the 4:47 PM heat-dome surge — gets answered live. No voicemail, no "all agents busy."
Asks zip code, system age, brand, and urgency against your service menu — then routes emergencies, schedulables, and maintenance differently.
Drops appointments straight into Google Calendar or Outlook with the right time window for the job type. Texts the homeowner a confirmation.
Your pricing, service area, brands you service, emergency policy — all wired in under an hour. Calls sound like you, not a generic robot.
Three real scenarios your shop sees every week — and exactly how the AI receptionist runs each one, start to finish.
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.
Hi — my AC just died and it's unbearable in here. I have a baby, I need someone out today.
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?
85282. It's a Carrier, probably 12 years old.
Got it — Tempe, you're inside our service area. Is the outdoor unit totally silent, or is it running but not cooling?
Totally silent. I already checked the breaker.
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?
602-555-0144.
Perfect — you're booked. The tech's name and a live ETA will hit your phone within ten minutes.
A repeat customer calls in late March wanting his spring AC checkup before the desert season hits.
Hey, I'm due for my spring tune-up. Johnson, I think you came out last fall for the heat side.
Thanks for calling back — let me pull you up. Can I confirm the address on file so I grab the right system?
4418 East Palm Lane, Phoenix.
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?
Thursday the 7th, 10 AM.
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?
No, it was fine all winter.
Perfect — I'll just flag it as a standard spring PM. See you Thursday.
A homeowner's Trane heat pump is making a loud hum and shutting off. He wants to know if it's worth fixing.
My Trane is making this awful hum and cycling off. It's old though — I'm wondering if I should just replace it.
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?
It was here when I bought the place — I think 2007? No warranty I know of.
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.
Okay, let's do that. Tomorrow if possible.
Can you give me the zip and a good cell? I've got a tomorrow 1–3 PM window open.
85044, and 480-555-0193.
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.
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.
