October 15 update: TavaTrack is no longer included because its current site markets roofing ads rather than receptionist plans. The old HVAC Receptionist AI directory link has also been removed because that listing is unpublished.

HVAC calls spike on the hottest and coldest days, exactly when your office can't keep up. An AI receptionist can capture system details and the address, request or book a visit where supported, and flag calls under rules you set. It is not guaranteed to answer every call, diagnose urgency or reach an on-call technician.

We compared the AI receptionists on TradesAnswered using each vendor's published pricing and feature pages (checked September 2026). We haven't live-tested every product, so use this as a shortlist and lean on the free trials.

What matters for an HVAC company

• Surge handling. Check included usage, fair-use terms, concurrent-call limits and overflow during heat waves. Flat pricing alone does not prove unlimited capacity.
• Urgent-call handoff. Set the trigger rules, on-call contacts and a no-answer fallback, then test them. A text or attempted transfer does not mean a technician has accepted the call.
• Booking into your system. ServiceTitan, Housecall Pro and Jobber users should check integrations first.
• Overflow vs. after-hours. Some shops only need coverage when the office is closed or slammed.

Before using emergency routing: Vendor-described triage, texts and transfers are not a diagnosis or a promise that someone will answer or attend. Set your urgency rules, on-call contacts and a fallback when nobody answers, then test them. For immediate police, fire or ambulance assistance in the US, call 911, not a contractor receptionist.

Our picks

Best flat rate for busy seasons: PickupBell

Built for HVAC and plumbing. PickupBell advertises one $199/mo plan with unlimited calls and minutes, round-the-clock answering, job booking and spam filtering. These are published features, not performance guarantees we tested. Integrates with ServiceTitan and Housecall Pro. 7-day free trial, no card.

Best per-call pricing: OnCrew

OnCrew describes rule-based urgency flags, live transfers and on-call rotation, priced by answered calls: $49/mo (100 calls), $149/mo (400), $349/mo (1,000), then $0.99 each. 14-day free trial, no card.

OnCrew's Housecall Pro connection needs Housecall Pro MAX and creates a customer and lead. Google Calendar receives appointment requests. Jobber and ServiceTitan receive call records through a webhook export, not direct schedule booking. These connections are included on all OnCrew plans.

Best for large ServiceTitan shops: ServiceTitan AI Voice Agent or Avoca

ServiceTitan's own voice agent books natively and uses per-call pricing; ask ServiceTitan for its current rate and any volume or commitment terms. Avoca offers custom pricing and deep ServiceTitan integration for shops with several CSRs.

Published $0-overage offer: Frankie

Frankie publishes Core at $199/mo with 500 calls per month and $0 overage. Confirm overflow and fair-use handling; this is not evidence of unlimited call capacity.

Quick comparison

How to choose

Look at your peak month, not your average. Ask each vendor to price that workload and explain concurrent calls, overflow, fair use and outages. Unlimited billing language does not guarantee every call is answered. If most of your work is booked through ServiceTitan, compare its native agent's per-call cost against a flat plan at your real volume.
