## What is CoolOps?

Built for solo HVAC technicians who do the work AND the paperwork.

Invoice the customer before you leave the site, log refrigerant in seconds, and keep your records straight — all from your iPhone, fully offline.

INVOICE ON SITE
• Quick invoices with service presets and line items.
• Auto-pull the refrigerant you just logged into the invoice.
• Generate a clean PDF and capture the customer's signature on the spot.

REFRIGERANT RECORDS
Federal leak-repair rules changed on January 1, 2026: the charge threshold dropped from 50 lbs to 15 lbs for many HFC systems.
• Add, recover, and transfer refrigerant with all the fields you need: date, type, quantity, equipment, technician, EPA certification number.
• Automatic 12-month rolling leak rate, compared with the threshold you select — 10% comfort cooling, 20% commercial refrigeration, 30% IPR.
• Export a print-ready refrigerant service record PDF — share in a tap.
• Scan an equipment serial number with the camera — no more squinting at nameplates.
• Service history by equipment — look up any unit fast.

WORKS WITHOUT SIGNAL
• Everything is stored on your device — basements, rooftops, dead zones, no problem.
• No account or setup wizard to fight through.

WHY TECHS PICK IT
• Field-first: big targets, fast entry, made for gloved hands.
• One app for refrigerant records + invoicing instead of two or three.
• Flat, honest pricing — no per-user enterprise fees.

Start with a free trial, then go Pro for full access.

CoolOps is a record-keeping aid. It does not determine which federal or state rules apply to your equipment, and it is not legal or compliance advice.
