An AI receptionist for HVAC companies that catches the 2 am no-heat call

Nobody calls an HVAC company because they feel like it. They call because it's 95 degrees and the AC quit, usually after 5 pm. Here's how the AI catches those calls and what it does with the replacement quotes afterward.

Where HVAC companies actually lose the job

An HVAC company loses on both ends of the day. After hours, the no-heat and no-cool calls go to a voicemail the homeowner doesn't leave, or to an answering service that takes a message and can't book, and by morning that customer has a competitor's truck in the driveway. During the day, the replacement quotes you hand out ($8,000 to $15,000 decisions) sit for weeks while the customer gets a second opinion, and nobody in your office has time to chase them between dispatches.

Summer volume makes it worse: per-minute receptionist services bill you the most in the month you're busiest, and a human service handles one call at a time while three more ring through. And the marketing question never gets answered: LSA, Google Ads, the mailer, the maintenance-plan referrals, which one actually produced the installs?

What the AI does on a HVAC company call

The AI answers every call at once, as your company, at 2 pm and at 2 am. It sorts the call the way a good dispatcher would: no heat or no cool with someone vulnerable in the house is an emergency; a noisy unit or a tune-up request is routine. It asks the right things: system type if they know it, age, the symptom, whether they're an existing customer or on a maintenance plan, the address. Emergencies follow the rules you set: transfer to the on-call tech with a briefing, or book the first emergency slot on the calendar and text the tech. Routine calls get booked into open service slots after a free/busy check on your Google Calendar. Callers asking about a replacement get the instant-quote page for a range and a booked estimate for the real number.

Existing customers are recognized by caller ID against your leads and customers, so the AI treats a maintenance-plan member like one. Robocalls and parts salesmen are dropped.

What happens after the call

The replacement quote is where HVAC money hides, and follow-up is what finds it. After a system estimate goes out, the customer enters a text sequence at 24 hours, 3, 5 and 10 days, written for the HVAC conversation (financing, rebates, "the second opinion came in higher, didn't it?") and stopping the moment they answer. "We need to think about it" and "that's more than we budgeted" trigger a recovery script on the call itself. Missed calls get an instant text-back. Booked service calls get a reminder.

Every phone number you publish is tracked as a separate lead source, so the dashboard tells you booked revenue by channel: what the LSA spend returned versus the maintenance-plan referrals versus the truck wrap.

A week on the phone, HVAC company edition

Tuesday, 11:40 pm, July. A caller says the AC died and there's a newborn in the house. The AI flags it as an emergency, follows your rule, and transfers to the on-call tech with a 20-second briefing: address, symptom, system age, existing customer. Tech rolls at midnight. At 7:10 am two more calls come in at once, both routine no-cools; both are booked into the morning's open slots without anyone in the office touching them.

Wednesday you give a replacement quote on a 19-year-old system. The homeowner says they'll get a second opinion. The sequence starts that night; on day 5 they text back "the other guy was $1,400 higher, when can you install?" Friday, the dashboard: 38 calls, 24 service calls booked, 3 replacement quotes, one signed, and LSA produced two of the three quotes.

What AI Front Desk Helper does besides answer the phone

Answering the phone is the entry point, not the product. Here is the rest of what runs once a contractor is on AI Front Desk Helper:

• Booking that respects your calendar. Estimates land on your own Google Calendar after a free/busy check, so the AI never offers a slot you're already on a job for. Reschedules and cancellations move or remove the event.
• Estimate follow-up that doesn't quit. Text sequences at 24 hours, 3, 5 and 10 days on every quote that hasn't closed, written like a contractor, stopping the moment the customer replies.
• Objection detection. "Too expensive" or "need to think about it" triggers a recovery script instead of a polite goodbye.
• Instant online quotes. A branded quote-and-book page for your business (yours looks like quote.yourcompany.com) where customers get a ballpark price and pick a time, day or night.
• Outbound campaigns. AI calls and texts to your past-customer list for seasonal reactivation, win-backs and referral asks. You set the campaign; it dials.
• Google Business Profile, handled. Every new review gets an owner reply drafted for you; profile posts can be drafted, approved and scheduled weeks ahead; a profile health audit shows how you stack up against nearby competitors.
• Revenue coaching by lead source. Every phone number is tied to where it came from (Angi, LSA, Facebook, referral, yard sign), so the dashboard shows which marketing produces booked revenue and which to cut.
• Call coaching for your team. Scored calls, what to fix, and in-home estimate coaching for the people who sell.
• Franchise HQ. One rollup across every location for multi-unit operators.
• Reseller program. Agencies and consultants can offer the whole system under their own brand.

Setup for a HVAC company

One onboarding call. We load your services (repair, maintenance, replacement, IAQ if you sell it), your emergency rules and on-call rotation, your service area, your service calendar, and your rules for the instant-quote page. You forward your existing number or port it. Most HVAC companies are live within the week.

Pricing

Annual billing is two months free. No minute meter, no per-call charges, no setup fee, month to month.

Which plan for a HVAC company

HVAC companies almost always belong on Pro or Elite. Pro gets you calendar booking, emergency handling with transfers, and the replacement-quote follow-up. Elite adds the pieces a growing shop uses every week: outbound campaigns to your maintenance-plan and past-install list (spring and fall tune-up pushes, filter reminders, the 15-year-old-system replacement conversation), review replies, and revenue by lead source. Basic fits an owner-operator who wants after-hours coverage and lead capture and nothing more.
