Your business
Your revenue potential
First month free · No card · 15-min setup call
This is a ceiling, not a forecast. It takes the calls you say you are missing, assumes every one of them got answered, and assumes about a third of them would have become booked jobs. We have no answer rate of our own to quote you, which is what the free month is for.
Monthly plans, once the free month has earned it
The first month is free. After that, monthly plans start at $299, or you can pay per booked appointment. What you pay depends on how many calls you actually take, so we look at your numbers on the demo and tell you which plan covers it.
Starter
One to three trucks.
- Answers every call, 24/7

Pricing and Plan FAQs
Why is there no price on each plan?
The first month is free and monthly plans start at $299, so you know the floor before you talk to anyone. Past that it comes down to how many calls you actually take in a month. A table of three tiers usually pushes people into the wrong one, so we look at your call volume on the demo and tell you which plan covers it. That call takes about fifteen minutes.
What does the free month include?
A full month on your real line, with full transcripts of every call it takes. No card up front, no subscription and no setup fee. At the end of it you get a report — calls answered, appointments booked, recordings — and you either pick a plan or walk away owing nothing.
Can I change plans later?
Yes, you can upgrade or downgrade anytime. Changes prorate from your next billing cycle.
Do I need a contract?
No contracts required. All plans are month-to-month by default. We also offer discounts for annual billing.
What if the AI misses calls or makes mistakes?
It will get things wrong sometimes, and we would rather say so than quote an accuracy number we have not measured. What you get instead is the full transcript of every call, so you can read exactly what was said and ring the customer back if it went sideways. Tell us what it got wrong and we adjust how it answers.
How long does setup take?
Setup is one onboarding call. We configure the agent with your business name, services and how you want the phone answered, run test calls with you, and you forward your number when you are happy with it.
What happens during the demo?
It's a 15-minute call where we give you a live walkthrough of how AI handles real HVAC calls, answer your questions, and recommend the best plan for your call volume.
How does the 90-day money-back guarantee work?
If you're not completely satisfied within the first 90 days, we'll refund 100% of your payments. No questions asked.

Not sure which plan you need?
Tell us roughly how many calls you get in a week and we will tell you which plan covers it. If starting with the free month makes more sense, we will say that instead.
