Honest comparison of the top AI answering services for HVAC businesses — features, pricing, booking rates, and which is right for your operation size.
Not all AI answering services are built for HVAC. A tool that works fine for a law firm or a dentist tends to fall apart when a homeowner calls about a no-heat emergency at 11pm and needs an answer in the next 90 seconds. This guide ranks the best options specifically for HVAC contractors — what each one does well, where it falls short, and who it makes sense for.
Before getting into the rankings, here's what separates a good HVAC-specific AI answering service from a generic one.
Generic AI answering services handle appointment scheduling across many industries. They're not trained on HVAC-specific scenarios: what a "no-cool" emergency means, how to handle a customer whose system failed during a heat wave, or how to qualify an HVAC installation request vs. a repair. HVAC-specific platforms are trained on these scenarios and perform significantly better on both booking rate and emergency handling. The right tool is the one built for your trade, not one adapted from a different industry.
Each service was evaluated on:
Best for: HVAC contractors with 1–15 trucks who want an all-in-one system
Artifact AI is built specifically for HVAC and plumbing businesses. The Phone Agent answers every call instantly, qualifies HVAC jobs by service type and urgency, books directly into your calendar, and triggers automatic follow-up for any lead that doesn't convert on the first call.
Artifact AI's Phone Agent picks up on the first ring and has a natural conversation with the caller. It understands HVAC job types (tune-ups, emergency repairs, system replacements, inspections) and routes each appropriately. Emergency calls trigger your preset escalation protocol. Routine appointments go directly into your dispatch calendar with a confirmation text to the customer.
The system is pre-trained on HVAC call scenarios, so you don't have to teach it from scratch. Emergency detection is built in — when a caller uses keywords like "no heat," "no cool," "system completely out," or "it's 95 degrees in here," the AI flags and escalates automatically. The Follow-Up feature fires a text within 60 seconds for any call that doesn't immediately convert to a booking.
ROI is typically visible within the first month. Getting back 5 additional jobs a month at $550 average ticket pays for the Starter plan nearly 10 times over.
Best for: Larger HVAC operations already running ServiceTitan
Avoca is the AI tool most deeply integrated with ServiceTitan. It's built for the enterprise end of the market and delivers excellent results for operations already embedded in the ServiceTitan ecosystem.
Avoca handles inbound calls, texts, and chats, using AI trained on your specific call recordings to improve over time. It integrates natively with ServiceTitan's dispatch board and can handle most common call types (lead qualification, appointment booking, and follow-up).
Aire Serv, using Avoca, went from 58 to 208 after-hours bookings per month after implementation. Booking rates consistently hit 90% (as of 2026). For ServiceTitan users who are already paying for the enterprise platform, Avoca is a natural extension.
Avoca's pricing is custom and tends to run higher than mid-market options. Best for established HVAC companies with 15+ trucks and a ServiceTitan investment already in place.
Best for: HVAC operators who want to build and customize their own AI flow
Goodcall offers a highly configurable AI phone agent that you can set up and adjust yourself without needing vendor support. It integrates with CRMs (or customer relationship management software) and calendars and can be customized for HVAC-specific use cases with enough setup time.
Goodcall answers calls, runs custom conversation flows you define, and integrates with your calendar and CRM. It's fast to deploy but requires more configuration than purpose-built HVAC tools to perform at the same level.
Goodcall offers a free tier with limited calls and paid plans starting around $49/month (as of 2026). At enterprise volumes, costs scale up. Good value for the configuration-minded operator.
Best for: HVAC companies that want AI efficiency with a human fallback
ZyraTalk combines AI call handling with live human backup for calls that need a real person. The AI handles the majority of calls; complex or high-emotion situations escalate to a trained human agent.
ZyraTalk's AI answers calls, handles routine qualification and booking, and recognizes when a call needs a human and transfers seamlessly. They serve home services, legal, and healthcare, so their agents have some familiarity with service business call patterns.
If your HVAC business handles commercial accounts, has high-stakes emergency volume, or operates in a market where customer relationships are particularly relationship-driven, the hybrid model ensures that complex calls always get a human who can manage the nuance.
ZyraTalk's pricing is based on call volume and service level. Basic AI-only plans start around $199/month (as of 2026); hybrid plans run higher depending on live agent volume. You pay more for the human layer, but gain coverage for the edge cases where AI alone may fall short.
Best for: HVAC contractors who want to be live in under 5 minutes
Lacy AI emphasizes speed to deployment. Their platform can have you set up and live within minutes, making it attractive for contractors who want a fast fix rather than a deeply customized system.
Lacy AI handles inbound calls, qualifies leads, and books appointments for HVAC and other home service businesses. It offers a free tier and paid plans that scale with usage, making it accessible for smaller operations testing AI for the first time.
If you want to stop missing calls today with minimal configuration effort, Lacy AI is worth testing. The trade-off is less HVAC-specific depth than purpose-built platforms, but it's a significant improvement over voicemail immediately.
$9.99–$499/month (as of 2026) depending on plan and call volume. Very accessible entry point.
Best for: HVAC companies wanting calls, texts, and follow-up in one platform
Whippy handles voice calls plus automated text follow-up in an integrated platform. For contractors who want both inbound call handling and outbound lead engagement in a single tool, it's a strong option.
When a call comes in, Whippy handles it. When a lead comes in from a web form or missed call, Whippy follows up with automated texts. The unified view of all customer communication in one dashboard reduces the coordination overhead of running separate tools.
Whippy includes emergency handling configuration — you define what constitutes an emergency and what happens when one is detected. Less automated than purpose-built HVAC platforms but functional for most scenarios.
Whippy's pricing is usage-based and varies by call volume and features. Contact for custom pricing based on your call volume. If you need calls and texts managed from one dashboard and don't need deep HVAC-specific training out of the box, Whippy is worth a look.

At this size, budget and ease of use are paramount. You need something that works without a dedicated admin to manage it. Artifact AI Starter or Lacy AI are the strongest options — both are fast to set up and require minimal ongoing management.
You're missing enough calls that the ROI math gets significant fast. You also need FSM integration so AI bookings flow directly into your dispatch board without manual steps. Artifact AI Growth or Avoca (if you're on ServiceTitan) are the right tier.
At this scale, you want the deepest integrations, the best analytics, and potentially a hybrid model for your most important commercial accounts. Avoca (ServiceTitan) or Artifact AI Scale with escalation rules configured for your key accounts are the right fit.
Our top pick for most HVAC contractors, especially those with 1–15 trucks, is Artifact AI. It's purpose-built for HVAC and plumbing, covers phone answering, follow-up, scheduling, and reviews in one platform, and delivers a measurable ROI typically within the first month. If you're already deep in the ServiceTitan ecosystem, Avoca is worth evaluating. For contractors who want to test AI quickly with minimal setup, Lacy AI is a fast, low-risk entry point.
