Best AI receptionists for HVAC companies (2026)

What is the best AI receptionist for HVAC companies?

What should an HVAC business look for in an AI receptionist?

HVAC calls are not like salon or dental calls. The weather sets the volume, a fraction of the calls are genuine safety issues, and the job is only booked once the job is on a technician’s board. Five things separate the options for a heating and cooling shop. First, emergency triage should follow rules you write. For example, a gas-smell caller is told to leave the house, and a no-heat call goes to the on-call tech. Second, the receptionist should book into ServiceTitan, Jobber or Housecall Pro during the call, not leave a message to retype. Third, arrival windows should come from your real capacity and service area. Fourth, the plan should be priced for the first 95-degree week, so compare overage rates as well as entry prices. Finally, check what happens at 2 a.m. and whether a missed caller gets a text back.

Emergency triage on rules you write

The receptionist should sort calls by your definitions, not its own. A gas smell or a carbon monoxide alarm means telling the caller to leave the house and call the utility or 911 from outside. No heat with an infant or an elderly person at home, or no cooling during a heat advisory, usually goes to the on-call tech now. A noisy blower books into tomorrow. Ask who writes these rules, and ask to hear the gas-smell call.

Booking into ServiceTitan or your field-service software

A message that a CSR has to retype in the morning is not a booked job. Ask whether the vendor creates the customer, the job and the call notes in ServiceTitan (or Jobber or Housecall Pro) during the call, and whether it does that natively or through Zapier. Dispatch should see the system type and symptoms before assigning a tech.

Dispatch windows and service area

The receptionist should offer arrival windows from your real capacity, check the address against your service area, note whether the caller is on a maintenance plan so members get the priority you promise, and quote only the diagnostic or trip fee you put in the script. It should never price a replacement; that needs a comfort-advisor visit.

Seasonal surges priced sensibly

The first 95-degree week and the first hard freeze bring the calls. A per-call plan charges for every one of them, a per-caller plan charges for every new household, and a minute plan charges for talk time. None is wrong, but the overage rate decides your July bill, and some vendors do not publish one. Ask too how many calls it answers at the same moment.

After hours and missed calls

Keres AI estimates that 35–50% of HVAC demand arrives after hours, because furnaces and air conditioners fail on their own schedule, and urgent no-heat and no-cool calls do not wait for the office to open. That range is a Keres AI estimate, not a measured figure; the HVAC answering benchmarks show the reasoning. Check what happens at 2 a.m.: a booked visit, a transfer to on-call, or a voicemail. Check also whether a missed caller gets a text back, and whether the receptionist can answer in Spanish if your customers need it.

Which option suits which HVAC shop?

Keres AI (Remi)

Remi is the AI receptionist from Keres AI. Remi answers in two rings, 24/7, asks your intake questions (system type, symptoms, address), applies the emergency rules you set and books the visit into ServiceTitan, Google Calendar or HubSpot during the call, with other tools through Zapier. Remi also answers website chat, the text line and form enquiries, and texts back missed callers within 60 seconds. For example, a no-heat call at 2 a.m. can go straight to the on-call tech while a noisy-blower call books into tomorrow. Billing is one monthly rate with included minutes, then per minute, with no per-call fees, and Keres AI does the setup for you. Limitations: the price is quoted to your volume, not published; Remi answers in English only; and Jobber and Housecall Pro integrations are still rolling out.

Avoca

Avoca sells an AI CSR for home service trades, with HVAC first on its industry list. Its HVAC page says the AI books jobs into your CRM, routes emergencies, and can transfer to Avoca’s own human CSR team when the AI cannot handle a call; it has a dedicated ServiceTitan integration page and also sells speed-to-lead, Google LSA and outbound campaign tools. It suits larger ServiceTitan shops that want a wider front-office suite. Avoca publishes no prices, so you cannot compare its cost without a demo.

Sameday AI

Sameday AI is an AI CSR for home service businesses, HVAC among them. Its Launch plan starts at $449 a month with 500 minutes and three locations; Scale starts at $789 with 1,000 minutes and unlimited locations, and both include “Pro scheduling (ServiceTitan etc)”. It suits multi-truck shops that want ServiceTitan scheduling from a trade specialist. The pricing page does not publish an overage rate, so ask what a heat-wave month costs past the included minutes.

Smith.ai

Smith.ai mixes AI with North America-based live receptionists. Its HVAC page says the AI handles routine scheduling while people take emergency coordination and upset customers, and it links its ServiceTitan integration. Billing is per call: the AI receptionist is free for 25 calls a month and then $3 a call; human plans start at $300 for 30 calls. It suits shops that want a person available on hard calls. In a surge week, per-call billing grows with every call, short or long.

Rosie

Rosie is a self-serve AI answering service with English and Spanish on every call. Its $49 plan includes 250 minutes and sends appointment links by text; booking directly on your calendar starts on the $149 Scale plan with 1,000 minutes. Its HVAC page says it sorts urgent from non-urgent calls and notifies you, but that it cannot dispatch technicians directly. It suits owner-operators with a light call load.

Goodcall

Goodcall is a self-serve AI agent billed per unique caller: $79 a month covers 100 different callers, then 79¢ each, and a repeat caller counts once a month. Its HVAC page argues this absorbs seasonal spikes and says Zapier connects it to ServiceTitan, Jobber and Housecall Pro. It suits shops with many repeat callers. A heat wave that brings many first-time households still raises the bill caller by caller.

How did we choose these HVAC options?

Each vendor here markets to HVAC or home service companies on its own site; the table links the page where each vendor does so. We recorded four facts for every option on October 11, 2026. First, who answers: AI, people or both. Second, how the service bills: per minute, per call or per caller. Third, the lowest plan the vendor publishes. Finally, how the vendor’s own HVAC page describes the fit. For example, Goodcall’s HVAC page says per-caller billing ($79 a month for 100 callers) absorbs seasonal spikes, and the table reports the vendor’s claim without testing the billing. The guide is a comparison of published information, not a call-quality test, and there is no overall winner. Vendors without a published price are marked “Not published” rather than estimated. Keres AI wrote the guide and sells Remi, which appears in the same columns under the same rules.

How much does an AI receptionist cost for an HVAC company?

Published entry prices for the HVAC options above run from $49 a month (Rosie, 250 minutes) and $79 (Goodcall, 100 callers) to $449 (Sameday AI, 500 minutes). Smith.ai’s AI tier is free for 25 calls, then $3 a call. Avoca does not publish prices, and Keres AI quotes Remi to your volume. For comparison, the U.S. Bureau of Labor Statistics puts the national median wage for receptionists at $38,010 a year (BLS, May 2025), before payroll taxes and benefits. For an HVAC company the useful number is the cost of your busiest month. First, size the plan to July or January. Next, compare overage rates, because Sameday AI does not publish one. Finally, price the next tier up: Sameday AI’s Scale plan starts at $789 for 1,000 minutes. The AI receptionist cost guide works out what 100 calls cost on each published plan, and the HVAC missed-call calculator puts a figure on the calls you miss now.
