ROI
7 min 2026-10-27 Short answer: most AI assistants built for HVAC and trades technicians are priced per user (per seat) per month, often with a monthly limit on questions. Brixon, for example, starts at $2.99 per month for a single technician and $20 per seat per month for company plans, with a free first question and a 14-day team trial. The price matters less than what you get for it: sources you can check, a shared history of your team's solved problems, and your own manuals searched for every tech.

Most HVAC company owners have already seen a tech pull out a phone on a job and ask a general chatbot about a fault code. Some answers are useful. Some are confidently wrong. And none of them stay with your company: the next tech who hits the same problem starts from zero.
That's usually when an owner starts looking at tools built for the trade, and the first question is simple: what does it cost, and is it worth it?
This guide explains how these tools are typically priced, what drives the cost, the costs people forget, and what to compare before you pay for anything, including Brixon.
Pricing models vary, but you'll mostly see some combination of these:
Per seat, per month. You pay for each person who uses the tool. This is the most common model for business software. It's easy to predict, and it grows with your team.
A monthly limit on questions or "requests." Each question a tech asks uses one request. Plans include a set number per month. When a tech runs out, they either wait for the next month or buy more.
Tiers by usage and features. Higher plans usually include more requests, more storage for your documents, and extras such as branding or admin features.
Free trials or free questions. A way to test the tool on real problems before paying. A trial on your own jobs tells you more than any demo.
Here is exactly how Brixon is priced today (monthly, per seat, cancel anytime):
| Plan | Price | Requests per month | Best for |
|---|---|---|---|
| Field | $0.99 first month, then $2.99/month | 30 | A solo technician |
| Basic | $20 per seat | 500 | Small teams |
| Pro | $40 per seat | 1,500 | Busy teams that use it daily |
| Premium | $80 per seat | 3,500 | Heavy use, with white-label branding |
A few details that matter:
The sticker price per seat is only part of the picture. These are the things that really decide what you'll spend:
How many techs need it. Not everyone needs a seat on day one. Many companies start with the techs who call for help most often, usually newer techs, and expand if it works.
How often they'll use it. A tech who uses it a few times a week fits a smaller plan. A team running commercial service calls all day may need a higher request limit.
Whether you need shared knowledge. If you want your team's solved problems and your manuals available to everyone, you need a company plan rather than individual accounts.
Document storage. If you plan to upload a large library of manuals, check how much storage each plan includes.
Whatever tool you choose, keep these in mind:
Time to get the team using it. A tool nobody opens is the most expensive one. Plan a simple rollout: one or two techs first, a short explanation, and a check-in after a week.
The cost of wrong answers. A cheap tool that sends a tech down the wrong path can cost more than it saves: a wasted hour, a part that didn't need replacing, or a callback. This is why sources and honesty about uncertainty matter more than a low price.
Knowledge that walks out the door. If solved problems live only in one person's head or one person's chat history, you pay to solve them again every time. (More on this in the tribal knowledge trap.)
Use this checklist for any AI assistant you're considering, Brixon included:
You don't need industry averages. Use your own numbers:
If a tool saves even a small part of that time each month, the math usually becomes clear quickly. If it doesn't, you'll know within a trial.
Brixon is built to help your techs diagnose: it suggests the checks to do first, shows sources when available, and keeps your team's solved fixes. It doesn't replace their judgment on the unit in front of them.
Most are priced per user per month. Brixon costs $2.99 per month for a single technician (after a $0.99 first month) and $20, $40 or $80 per seat per month for company plans, depending on how many requests your team needs.
Yes. Your first question is free with no account and no card, and you get two more questions when you create a free account. Teams can also start a 14-day trial.
Per technician (per seat). Company plans are multi-seat and share your team's solved fixes and uploaded manuals across everyone on the account.
Company admins can add extra requests during the month, or move to a plan with a higher monthly limit.
Yes. Plans are monthly and can be cancelled anytime.
General chatbots can help with general questions, but they don't know your manuals, they don't keep your team's solved problems, and they may not show where an answer comes from. For a team, shared knowledge and checkable sources are usually what make the difference.
No. Brixon helps technicians narrow down the cause of a fault and shows sources when available. The technician still verifies on site and makes the call.
Commercial HVAC and BAS, including chillers, RTUs, VRF, air handlers, drives, BACnet and Modbus controls, and pumps. Answers are strongest when you upload the manuals for the equipment you service.
