HVAC runs on recurring work: maintenance agreements, seasonal PMs, emergency calls, and the dispatch board that ties it all together. Most HVAC software makes you fit your business to its template. EVIOS builds custom software around how your HVAC business actually runs and connects it to the tools you already use, including QuickBooks.
That means agreement renewals and PMs that schedule themselves the way you want, a dispatch board that matches how you really assign calls, techs invoicing from the field, and job costing that shows real margin, without a per-seat platform you have to move everything into.
You keep the systems that already work, we build the recurring-work and dispatch pieces around them, and you pay a fixed cost to build it instead of a monthly bill per technician.
What slows an HVAC shop down
The hard part is rarely the install. It is keeping the recurring work and the board under control.
Built for recurring work, connected to QuickBooks
We build the workflows HVAC actually lives on, then connect them to what you already run. Agreements track renewals and trigger PMs automatically. The dispatch board reflects how you really schedule. Hours and parts from the field flow into payroll and your accounting instead of being typed in twice.
You keep the tools that work, you are not paying per technician every month, and you own what we build.
Because it is shaped to your shop, it handles your specific mix of agreements, service calls and installs, rather than forcing all of it through a one-size module.
Off-the-shelf vs built for your shop
What we build for HVAC contractors
We begin with whatever is costing you the most, recurring revenue you are leaving on the table or time lost on the board.
From audit to running, three steps
Free audit
We map where time and money leak out of your jobs and show you exactly what we would build first, with a fixed cost up front.
We build and connect
We build the custom piece and wire it into the tools you already use, so nothing gets re-keyed and your team is not relearning everything.
We run it for you
It goes live, we support it, and we adjust it as your business changes. Fixed cost to build, small hosting after, no per-seat.
Is custom right for your HVAC business?
If you are a small shop with a handful of calls a week and a basic app keeps you organized, an off-the-shelf product is probably enough, and we will say so.
EVIOS pays off when recurring agreements are real money, the dispatch board is getting hard to run by hand, and a per-seat platform is charging you more as you grow. A free audit will show you whether you are at that point.

Does your HVAC software handle maintenance agreements?
Yes. Recurring agreements are central to HVAC, so we build agreement tracking that handles renewals and triggers PMs automatically, shaped around how you actually sell and service them.
Does it connect to QuickBooks?
Yes. We build around your existing accounting and connect to QuickBooks so hours, parts, job costs and agreement billing flow through automatically.
Can techs invoice from the field?
Yes. The field app lets technicians log hours and parts and invoice on site, so nothing gets re-keyed back at the office.
Is it priced per technician?
No. You pay a fixed cost to build it and a small hosting cost to run it, so adding techs does not raise your software bill.
Do I have to replace what I already use?
No. You keep the tools that work and we build and connect only the parts slowing you down.
Can it schedule seasonal PMs automatically?
Yes. We build the agreement and PM scheduling around your seasons and renewal windows, so recurring visits get booked without someone tracking them by hand.
