Best AI Receptionist for HVAC Companies (2026)
A missed call in July is often a missed install. HVAC demand spikes with the weather, after-hours emergencies are common, and a small office can't staff the phones around the clock. In ServiceTitan's 2026 State of AI in the Trades survey, 34% of contractors said providing after-hours support was a reason they were trying AI (Contracting Business).
An AI receptionist answers every call, captures the caller's details, and in many cases books the job directly. Below are the options in our directory that list HVAC support, grouped by the size of shop they fit best.

What to look for in an HVAC AI receptionist
- Booking, not just messages. The best value comes when the AI puts the job on the board. Check whether it books into your scheduling software or only sends you a text.
- Emergency handling. Make sure you can set rules for no-heat and no-cool calls, such as transferring to the on-call tech.
- Minute or call caps. Entry plans often cap minutes or calls. Estimate your peak-season call volume, not your average.
- Trade-specific workflows. Tools built for the trades (Avoca, Sameday, Netic) are designed around home service dispatch and scheduling. General tools are cheaper but need more setup.
- A human fallback. Some callers want a person. Smith.ai pairs AI with live agents.
Best for small HVAC shops (1-10 techs)
Upfirst has the lowest paid entry price in this guide and a 14-day free trial. It trains from your website, and you can customize the questions it asks callers. The Starter plan includes 30 calls a month. It's a general-purpose tool rather than an HVAC-specific one, so expect to write your own call scripts.
Rosie is a simple 24/7 AI answering service. The $49 Professional plan includes 250 minutes, custom message taking, appointment links sent by text, and automatic spam detection. Booking directly on your calendar starts with the $149 Scale plan, and 250 minutes may run short in peak season.
Dialzara starts at $29/mo for 60 minutes of talk time, with a 7-day free trial and no contract. Outbound calling and the AI SMS agent are priced separately; a website chatbot is bundled with its voice plans.
Goodcall builds an agent from a plain-English description of your business, your website, or your Google listing, so you can build and test one before you pay. There's no traditional free trial; you start with a free demo agent instead.
Frontdesk covers voice, chat and two-way SMS in one plan, with a built-in CRM and automations. The entry plan includes 200 voice minutes a month.
Best for shops that want a human backup
Smith.ai answers with AI first and can transfer complex calls to a live North America-based receptionist. A free tier covers 25 calls a month ($3 per call after that), which is a low-risk way to test. Paid plans start at $150/mo and are priced per call, which can add up for busy shops.
Best for pay-as-you-go
Newo.ai has a $0/mo pay-as-you-go option: new accounts get 50 free units, then pay $1.75 per unit (roughly one voice call). Spam calls disconnected within 30 seconds, immediate hang-ups and calls that never connect aren't billed. At high volume, its $299/mo plan (200 units, then $1.50 each) may work out cheaper.
Best for mid-size and growing HVAC companies
Sameday AI is built for home service trades. Plans start at $449/mo with 500 minutes, unlimited users and ServiceTitan scheduling integration. Beyond answering calls, its outbound campaigns work your customer list by call and text: reactivation, maintenance reminders, estimate follow-ups and review requests.
Avoca AI is built for the trades and aimed at heavy call volume. A customer quoted on Avoca's website says Avoca handles 70% of its call volume (a vendor-published testimonial). Pricing requires a demo.
Netic handles inbound demand across channels and runs automated outbound campaigns, with a focus on larger service companies. Pricing is quote-based.
Already on a field service platform?
Your FSM software may offer AI answering of its own. Jobber sells an AI Receptionist add-on for $29/mo that can answer questions, take requests and book jobs on your calendar. Housecall Pro offers an AI CSR that answers calls and books jobs 24/7, and ServiceTitan offers an AI Virtual Agent. In ServiceTitan's 2026 survey, 61% of AI users said they prefer AI built into their core software. Compare the add-on's cost and booking depth against a standalone tool before deciding. See all scheduling platforms in Field Service Management, Scheduling & Dispatch.
Don't forget your website
Many HVAC leads arrive by web form or chat after hours. Pair your phone AI with a website chat and lead capture tool such as Podium or Tidio, or follow up paid leads instantly with LeadTruffle.
FAQ
How much does an AI receptionist cost for an HVAC company?
Published entry pricing for the tools in this guide ranges from free tiers (Smith.ai, Newo.ai) and about $20 to $29 a month (Upfirst, Dialzara) up to $449 a month for Sameday AI's trade-focused plan, and every entry plan caps calls or minutes. Avoca AI and Netic, which target larger shops, quote pricing after a demo.
Can an AI receptionist handle HVAC emergency calls?
Most let you set rules to transfer urgent calls or alert an on-call tech. Test this during your trial with a few mock no-heat calls.
Will customers know they're talking to AI?
Often, yes. Most owners find callers care more about getting a fast answer and a booked appointment. Tools with a human fallback, like Smith.ai, cover callers who insist on a person.
