How we picked

  • Directory only. Every pick is a live listing tagged HVAC in our data. Of the 38, 32 publish pricing and 18 offer a free trial or free plan.
  • Emergency triage. We favour vendors whose own pages describe emergency or urgent-call handling (rules, on-call alerts, transfers). No-heat and no-cool calls at night are the calls that matter most.
  • Field service software fit. Jobber, Housecall Pro and ServiceTitan shops get picks that name that software.
  • Published price preferred. Quote-only products can still be picks; their price shows as Not published.
  • Easy to test. A free trial, a no-card start or a public demo line counts in a vendor's favour.

No star ratings or reviews. See our methodology.

Best for emergency and no-heat, no-cool triage

Pick: OnCrew. OnCrew is built for trades. It answers in two rings, applies your emergency triage rules, and texts or live-transfers the on-call tech, with emailed recordings and transcripts. Plans as published: Starter $49/mo (100 calls); Pro $149/mo (400 calls); Multi-Truck $349/mo (1,000 calls); $0.99 per extra call. Trial: Free trial, 14 days, no card required, plus a 30-day money-back guarantee.

Also consider: Callbook, which lists urgent job routing and answers in English and Spanish, and AgentZap for urgency detection with human backup. Callbook's entry plan: $79/mo (250 AI min, first month $49); trial: Not stated.

Whatever you pick, call after hours with "my furnace is out and it's freezing", then check who got alerted, how fast, and what the caller was told.

Best if you already run Jobber

Pick: Jobber Receptionist. It answers calls and texts 24/7, books visits using your Jobber online booking settings, creates work requests and escalates urgent calls by keyword. Jobber does not publish a separate price for it: the no-card free trial is for the Jobber platform, and the AI Receptionist may be a paid add-on. Ask Jobber for the add-on price in writing.

Standalone option: ConvoForms (Gus) answers 24/7 and creates real Jobber clients, requests and visits. Pricing as published: $49/mo including 600 minutes; $0.30 per extra minute only if you opt in. No contract. Trial: Free trial, 14 days, no card required. KaiCalls and Lippy AI also list Jobber.

Best if you already run Housecall Pro

Pick: Housecall Pro CSR AI. Built into Housecall Pro, it answers calls and chats 24/7, books jobs into your schedule and uses your price book, services and availability, with custom scripts, hours and escalation rules. Voice pricing is not published, so treat it as quote only. Housecall Pro's platform trial runs 14 days.

Other vendors that list Housecall Pro: AgentZap, DialIQ, KaiCalls, Lippy AI and Sameday. Ask whether each books into the schedule or only passes lead details.

On ServiceTitan instead? Avoca AI, Sameday and Hatch all list ServiceTitan. Starting prices as published: Avoca AI: Not published; Sameday: Launch from $449/mo (500 min, 3 locations); Hatch: Not published.

Best published low entry price

Pick: Upfirst. Entry plan as published: Starter $24.95/mo (30 calls, $1.50/extra). It can answer 24/7, overflow-only or after hours, so it can back up an office manager instead of replacing them. Trial: Free trial, 14 days.

Other low entry points as published: KaiCalls Kai Backup $10/mo (~20 answered calls), Dialzara Business Lite $29/mo (60 min, $0.48/min over), Marlie Basic $49/mo (250 min, then $0.35/min) and Rosie Professional $49/mo (250 min). Per-call and per-minute plans behave differently in a heatwave, so check your average call length; Marlie vs OnCrew puts a per-minute plan next to a per-call one.

Best hybrid with human backup

Pick: AgentZap. AgentZap lists live human agent backup, alongside urgency detection, real-time calendar booking and ServiceTitan and Housecall Pro integrations. Pricing as published: Starter $109/mo (150 min, $0.85/min overage); Professional $295/mo (450 min, $0.75/min); Business $899/mo (1,500 min, $0.70/min); Enterprise custom. $499 one-time training and setup fee (waived on a 6-month Professional term). Fully managed plan also offered. Free trial: Not offered; it offers a 30-day money-back guarantee.

Smith.ai and Abby Connect sell human receptionists too, but they are not tagged HVAC in our data. See AI receptionist vs human receptionist for how hybrids work.

What "answering service" means on this page

Classic answering services use human agents who take messages. Most HVAC tools sold as an "AI answering service" are AI receptionists that answer, triage and often book. Our AI answering service vs AI receptionist guide explains the difference, and the cost guide compares pricing models.

Not usually for routine booking and triage, but keep a human path for unusual or distressed callers. AgentZap pairs AI with live agent backup.
