HVAC AI answering service that books the 9 PM no-heat call

Built for no-heat nights, not business hours

HVAC work doesn't happen at a desk. Your techs are in attics and crawlspaces, and the calls that matter most — the furnace that quits at 9 PM in January — land exactly when nobody can pick up. Invoca's research puts numbers on it: home services businesses miss about 27% of inbound calls, and the average missed call costs around $1,200 in lost work. A Fasrad HVAC AI answering service answers every one of those calls instantly, asks your triage questions, and books the window while your competitor's phone is still ringing.

This is not a message-taker. The agent runs the safety and triage questions you give it, checks your real calendar during the call, and confirms the first emergency window that fits. The caller hangs up with a booked time; you wake up to a scheduled job with the address, the symptoms, and the full transcript already in your CRM.

HVAC-specific proof points:

• Emergency triage first — a no-heat call gets your safety questions (any gas odor?) before any scheduling, and urgent jobs are flagged that way in the summary.
• Real windows, booked mid-call — the agent reads tomorrow's emergency slots from your calendar and confirms one on the spot. No "someone will call you back."
• Address and symptoms captured — street address, what the system is doing, who's in the house, all logged so the tech rolls up prepared.
• Returning callers recognized — the customer whose AC you fixed in July is remembered in January, service history and all.
• Cold-snap surge coverage — when the first freeze lights up your line, the fifth simultaneous caller gets the same instant answer as the first.

Example: a 9 PM caller with a dead furnace and a toddler in the house gets a gas-odor check, a confirmed 7–9 AM emergency window, and a confirmation email — and you get a new contact, a summary, and the full transcript before your morning coffee.

A human answering service takes a message at roughly $10 a call, and the job still isn't booked. Fasrad's receptionist is a full agent: the same brain answers your website chat and email, books into the same calendar, and files everything into the same CRM — for a flat subscription.

Frequently asked questions

Does it sound like a robot?

No. It speaks in a natural voice and callers can interrupt it mid-sentence, the way they would a person. It also answers in the caller's language — useful when the no-heat call comes in Spanish.

Does it actually book the job, or just take a message?

It books. The agent checks your calendar during the call and confirms a real service window before the caller hangs up. Message-taking is the thing it replaces.

What do I see after a call?

A contact, a summary note, and the full transcript filed in Fasrad's built-in CRM, plus the booked window on your calendar. The caller gets a confirmation email.

What if a caller smells gas?

You set the rule and the agent follows it — for example, telling the caller to leave the house and call their gas utility, then flagging the call urgent in the summary. It never improvises repair advice.

Do I have to change my phone number?

No. We provision a dedicated number in minutes and you forward your existing line to it with standard carrier forwarding. Customers keep dialing the number they know.

How much does it cost?

$49/month or $490/year — cancel anytime. Flat subscription — no per-minute or per-call fees.
