The Problem

Running an HVAC business
on spreadsheets and WhatsApp?

Most HVAC companies lose money because of operational chaos. Zeno fixes all of it.

📋

No visibility on service jobs

You don't know which technician is where, what was done on site, or whether the job is billable.

📦

Inventory always out of sync

Materials go missing, stock records are wrong, and you find out only when a job gets delayed.

📅

AMC contracts slipping

Renewal dates missed, visits not tracked, clients not invoiced on time — revenue leaking silently.

🔧

Tools and assets unaccounted

Expensive tools lost, no record of which technician has what, no accountability.

💰

Billing always delayed

Jobs completed but invoices raised weeks later. Cash flow suffers because of manual processes.

📊

No financial visibility

You don't know project profitability, technician costs, or which clients are most valuable.

business needs, in one place

FAQ

Frequently asked questions

Everything you want to know before booking a demo.

No. Zeno works for HVAC companies of all sizes — from 5-person service teams to 100+ technician operations. The module system lets you start with what you need and add more as you grow.
Yes. Zeno is a responsive web app that works on any smartphone browser. Technicians can view assigned jobs, update status, submit expenses, request materials, and capture site photos directly from the field. No app download required.
You create an AMC contract with frequency, contract value, and linked machines. Zeno automatically calculates the next invoice date, tracks visits, and generates invoices on time. Contract status auto-moves to Expired when end date passes.
Yes. The Site Machines register stores GPS coordinates for every installed unit — along with machine type, brand, model, serial number, capacity (TR), installation date, and warranty expiry.
Zeno uses a ledger-first inventory system. Every material movement creates an immutable transaction. Stock is always reconstructable from history. Negative stock is blocked. For projects, you can set material budgets per stage and track consumption in real time.
Yes. The Assets module maintains a full custody chain for every tool or asset. When you transfer an asset to a technician, a transfer record is created. Every movement is logged. You always know which technician has which asset at any point in time.
Yes. Zeno has a built-in Tally Export module. You can export financial transactions, invoices, and payments as Tally-compatible XML files — eliminating double data entry.
Zeno is built as a multi-tenant SaaS platform with strict data isolation. Every record is tagged with a company ID and all queries are filtered. It is architecturally impossible for one company to access another company's data.
Pricing is based on team size and modules required. We offer flexible plans for small service companies, growing contractors, and large multi-branch operations. Book a demo and we'll give you a custom quote.
Most companies are fully operational within 3–5 working days. After your demo, we handle account setup, help import your client and machine data, add your team, and run a training session.
