The F-Gas app that does the CO₂e maths on the form
Pick the refrigerant and enter the charge. Maintivo applies the GWP, converts the kilos to tonnes of CO₂e, works out which leak-check band the system falls into, and sets the next-check-due date against the unit. Then it sends the customer a branded PDF record before the gauges are back in the van.
The sum that is quietly easy to get wrong
A charge in kilograms tells you nothing on its own. What matters is the tonnes of CO₂e it works out to, because that is what sets your leak-check interval. Do the conversion wrong once and you check that system at the wrong interval for a whole year without ever knowing.
Maintivo does the sum on the form and shows its working, so the interval is not a judgement call made in a plant room with a calculator.
What the app does on an F-Gas job
Open the Split AC or VRF leak check, or the Chiller service and F-Gas form. Pick the refrigerant and type in the charge. Maintivo applies that gas's GWP, turns the kilos into tonnes of CO₂e, tells you which leak-check band that puts the system in, and writes the next-check-due date against the unit in your asset register. The refrigerant designation and charge weight print on the record exactly as you entered them.
The next check, tracked and chased
The unit sits in your asset register with its next-check-due date. Ninety days before it is due, you get a nudge. Thirty days before, another. And again if it slips. Renewals stop being the thing you find out about from an angry site manager.
Works on the roof with no signal
Signal dies on rooftops, in risers and in ceiling voids. Maintivo captures the entire job offline, readings, photos and the customer's signature included, and uploads it by itself the moment you are back in range. Nothing is retyped in the van.
You sign it. Maintivo keeps the record.
You are the F-Gas certified engineer. You carry out the checks and you sign the record, and you remain the competent person. Maintivo does not certify the work. It produces a clean record with your F-Gas certification number on it, sends it as a branded PDF, and keeps every copy searchable in UK-GDPR secure cloud storage.

Common questions
Yes, this is the part it is built for. You pick the refrigerant and enter the charge in kilograms. Maintivo applies that gas's GWP, converts the charge to tonnes of CO₂e, works out which leak-check interval band the system falls into, and sets the next-check-due date against the unit in your asset register. Get that sum wrong by hand and you check the system at the wrong interval for a year, so the app does it on the form and shows its working.
There are two ready-made F-Gas forms: a Split AC or VRF leak check, and a Chiller service and F-Gas. Common refrigerants such as R32, R410A and R134a are supported, and the refrigerant designation and charge weight print on the record exactly as entered. Sections that do not apply are hidden, so if the system holds no F-gas the leak-check section is not there.
Yes. The unit goes into your asset register with its next-check-due date, and Maintivo nudges you at 90 days out, 30 days out, and again if it goes overdue, so you find out before the client does.
Maintivo Pro is £34.99 a month with a 3-day free trial. Additional engineer seats start at £8.99 a month, and invoicing is an optional £9.99 a month add-on. No contract and no exit fee.
