Best AI answering service for HVAC, plumbing and roofing
Updated September 20, 2026
For a 1 to 5 truck HVAC, plumbing or roofing shop, the best AI answering service is missed call text-back, not an AI voice receptionist. The caller gets a text from a local number within about 30 seconds, answers the questions a dispatcher for that trade would ask, and the job lands in your inbox. AnswerBot does this for $129 CAD a month, flat. No AI voice ever talks to your customers.
The category splits three ways: text-back services, AI voice receptionists that pick up and talk, and human answering services with AI assist. They are priced on different units, which is where most comparisons go wrong. Text-back is priced per month, voice is usually priced per call or per minute, and human services are priced per call. The table below uses each vendor's own published figures, with the date they were read.
The three options, side by side
| Text-back (AnswerBot) | AI voice receptionist | Human service with AI | |
|---|---|---|---|
| What your caller gets | A text from a local number within about 30 seconds, then a short conversation they answer in their own time | A bot that picks up the phone and talks to them live | A person, with AI assist, answering the call live |
| Published starting price | $129 CAD a month flat, no per-call or per-minute charge. $109 a month billed annually. USD is the same number. | Dialbox from $129 CAD for 100 AI-handled calls; Ask Benny from $99 CAD for 300 minutes, then about $0.45 a minute (as published August 2026) | Smith.ai from $300 USD for 30 calls (as published September 2026) |
| Photo of the leak, panel or roof | Yes, on Growth and Pro. It arrives attached to the lead. | No. A voice call cannot carry a photo. | Usually not during the call. |
| Questions asked | Intersection or address, first name, the issue, plus one detail per trade. Pro plans can replace these with your own. | Whatever script you configure, spoken | A script you agree with the service |
| Setup | About five minutes: one conditional call forwarding code dialed from the business phone. No app. | Call routing setup, usually a day or two | Onboarding call and script sign-off, usually a day or two |
| Your business number | You keep it. A dedicated local number takes the call only when you do not answer. | You keep it, with forwarding | You keep it, with forwarding |
| What it does not do | No appointment booking and no price quoting. It captures the lead and hands it to you. | Cannot see a photo; a caller who dislikes bots can hang up | Costs the most per captured lead at low volume |
Competitor prices are each vendor's published list price on the date shown, not a quote: Smith.ai and GoHighLevel read September 20, 2026; Dialbox and Ask Benny read August 2026. Check their sites for current terms. AnswerBot prices are CAD, and USD is the same number.
Where a CRM platform fits
GoHighLevel is the other name that comes up, at $97 USD a month for its Starter plan as published September 20, 2026. It is a full CRM platform with text-back as one feature among many, and you build and maintain the automation yourself. That is a fair trade if you want a marketing stack and have the evenings to wire it up. It is the wrong trade if what you want is for missed calls to stop costing you jobs by the end of the week.
Why text beats voice for these three trades
- •The job is visual. A homeowner can text a photo of the water under the tank or the shingles in the yard. You can size the job before you drive. A voice bot cannot see any of it.
- •The caller is busy too. They called between other things. A text lets them answer while the kettle boils, which is why a text conversation finishes when a live call would have been declined.
- •You get a written record. The intersection, the issue and the caller's name arrive typed, in their own words, instead of in a message someone took down.
What the text actually asks, by trade
Every caller gets the same three basics first: the nearest intersection or address, so you know the job is in your service area, their first name, and what is wrong. Then one detail for the trade. These are the defaults AnswerBot runs today, not a sample script.
| Trade | Trade detail asked | Photo asked for (Growth and Pro) |
|---|---|---|
| HVAC | How old the unit is, if they know, after the issue itself (no heat, no cool, leaking, short-cycling) | The unit, if it is reachable |
| Plumbing | Whether the shut-off is reachable, after the issue itself (leak, no hot water, clog) | The leak, if it is reachable |
| Roofing | The storm date, and whether they are filing insurance, after the issue itself (storm damage, leak, missing shingles) | The damage from the ground, if it is safely visible |
Electrical, garage door, locksmith, towing, appliance repair, landscaping and auto repair have their own defaults in the same shape. On Pro plans you can replace the lot with your own questions.
No annoying AI voice
People hang up on AI voices. A homeowner who has just been sent to voicemail does not want to argue with a robot on the next attempt. AnswerBot never puts an AI voice on the line. The missed caller gets a plain text, answers a few questions, and you call them back with the details already in hand.
If someone texts "can I talk to a person", the reply is that the owner will call them back. The text is the bridge to a human, not a replacement for one.
Who this is for, and who it is not for
For: owner-operators and 1 to 5 truck shops
You answer your own phone when you can and miss it when you are under a sink, on a roof or driving. HVAC, plumbing, electrical, roofing, garage door, locksmith, towing, appliance repair, landscaping and auto repair.
Not for: shops where someone already answers every call
If a person picks up every time, missed calls are not your problem and a live answering service is the better spend.
Not a booking tool
AnswerBot captures the lead and hands it to you. It does not book appointments or quote prices; a caller who asks for a price is told you will call them back.
When one of the others is the right call
If a call must be answered and routed while the caller is still on the line, a voice service earns its money and text-back does not replace it. If you run commercial work where a missed call is a contract rather than a service call, a human service at $300 USD for 30 calls can be cheap. And if your volume is a few minutes a month, metered voice pricing can beat a flat monthly fee. For a shop missing 5 to 15 calls a week, flat text-back is usually the lowest cost per captured job.
What it costs here
Starter is $129 CAD a month for 25 engaged leads and one location. Growth is $199 for 75 engaged leads, photo capture and up to three locations. Pro is $349 for unlimited engaged leads, your own intake questions and up to ten locations. Billed annually those are $109, $169 and $296 a month. USD is the same number. The trial is 14 days, a card is required at signup, and nothing is charged during the trial. Every text carries a STOP opt-out, which is what CASL requires in Canada.
