For air conditioning engineers

CRM & field app for air conditioning engineers — one system

From enquiry to sign-off in one system — air conditioning software, scheduling, quotes and invoicing. Built for air conditioning businesses doing splits, VRF, service contracts, commissioning. Less paperwork, more work.

Sound familiar, air conditioning engineers?

Service intervals per unit rather than per customer

Refrigerant records kept separately

Commercial sites with many units and one payer

The software for air conditioning engineers: CRM, job sheet app and invoicing

One customer record carries the whole business — from the first enquiry to the signed job sheet and the invoice.

CRM and enquiries

Every enquiry with the address, the history and a status, in a funnel you can read at a glance.

Field app

Survey, photos, job sheet and a signature on the phone, on the job.

Quotes and invoicing

Quotes and invoices in your own branding, emailed with a payment link on them — card, Apple Pay or Google Pay, or a transfer with the invoice number as reference.

Labour and materials kept apart

Split from the moment the work is recorded, which is what makes a CIS invoice come out right instead of being reconstructed.

Works without signal

No signal in the cellar or on a new build? The app keeps photos, sign-offs and hours on the device and sends them when the connection returns.

Chasing that runs itself

Follow-ups, appointment reminders and payment reminders switched on once. Built in, no separate tool and no extra subscription.

Scheduling

Jobs onto engineers and onto the week, with appointment reminders going out on their own.

Handover and sign-off documents

A tidy PDF with photos and your branding, produced when the job is signed off.

Time recording

Start and stop on the job in the app; the hours land on the invoice as a labour line with one click, so nothing shrinks on the way.

Service contracts

Recurring work with its own renewal date and its own reminder, and invoices raised without anyone remembering.

The file, on site

The engineer sees the survey, what was agreed and what was flagged last time — and you decide per photo and per message what goes to the customer.

Email onto the right job

Incoming mail lands against the right customer and the right job.

Move over in an afternoon

Bring your customers and price lists in from Excel or CSV in one go. No retyping.

Setup help

Type what you want to change and Quandron points at where it is set. Configuring works without a manual.

Your branding in one click

Enter your logo or your website address and Quandron picks up your colours for the app, the quotes and the invoices.

Common questions

Can I keep records per unit?

Yes. The appliance, not just the address, is what carries the history.

Does it cover F-gas record keeping?

A log per appliance: the charge, the refrigerant with its GWP and CO2e, every leak check with date and result, and the engineer's certificate number — what both regimes ask to see. Note that Great Britain and Northern Ireland run different regimes, which matters if you work both.

Can I run planned maintenance contracts?

Yes, with renewals on their own dates and reminders that go out without anyone remembering.
