The problem
A refrigeration shop's day without a system
If any of these sounds familiar, it's not that you work badly. It's that the notebook and WhatsApp can't keep up anymore.
01
Preventive visits slip past due
You only remember the maintenance when the customer calls because the unit already broke down. Every forgotten preventive visit is recurring income you gave away.
02
The tech shows up not knowing what to bring
What refrigerant does that chiller use? What was done last time? Without a unit record, every visit starts from zero.
03
Photos and reports get lost
The tech sends photos over WhatsApp, they get buried, and when the customer complains there is no record of what was done.
04
Contract billing slips away
You track monthly maintenance from memory or in Excel; some month you forget to invoice.
With Nodux
How Nodux puts your operation in order
Built for the tech who is on site, not for an office.
Preventive work that schedules itself
You set the frequency and the ticket is created on its own when it is due. No more forgotten maintenance.
Works with no signal
The tech logs the visit, the photos and the status offline in the mechanical room; it syncs on its own on the way back.
Quotes approved by link
You put the quote together on site and the customer approves it from their phone, with no calls and no back-and-forth.
Signed service report
A record with before/after photos and the customer's signature, in PDF. Your proof against any complaint.
Contracts that bill themselves
Recurring maintenance gets billed every month without you having to remember.
Questions about refrigeration and HVAC
Can I schedule preventive maintenance?
Yes. You set the cycle per unit and Nodux creates the work order when it is due, with its checklist. Preventive work stops depending on someone's memory.
Does it log the refrigerant type and the readings from each visit?
Yes. The refrigerant type goes in the unit record, and the report saves the readings from the visit (pressures, temperatures, superheat) according to your template.
The tech works on rooftops and in mechanical rooms with no signal. Does it work?
Yes. They log everything offline and it uploads when they get signal back. They don't lose the work for being on a rooftop.
Can I track several units per customer and see them together?
Yes. Each customer has their equipment with location and model, and you can see at a glance which unit fails the most, which is what justifies a replacement.
Can the customer see how their repair is going?
Yes, by link and with no account. That is what stops the "how is my job going?" calls before they happen.
Refrigeration is field service: your techs go on site. If you also have a shop where the work comes to you (countertop appliances, for example), Nodux covers that model too.
