The HVAC inspection app that does the F-Gas sum on the rooftop

Maintivo is an HVAC inspection app for UK air-conditioning and refrigeration engineers. It captures the service or inspection on site, on an iPhone or in the web app on Android and any browser, does the F-Gas leak-check maths on the form, works with no signal in the iPhone app, and has a branded PDF service report ready to send before you leave. Pro is £34.99 a month with a free trial and no contract.

The write-up is the worst part of an air-con service

The service itself is routine. You know the unit, you know the checks. What takes the evening is turning six jobs' worth of scribbled filter conditions, superheat figures and photos into six tidy reports a facilities manager will accept.

And on a rooftop or in a ceiling void, half the time you have no signal at all. So the notes go on paper, and paper gets typed up twice.

What Maintivo does on an HVAC job

You pick the form. Log the filter condition, the pressures, supply and return temperatures, and any fault you find, each with its own photo and the next move.

Then it does the bit nobody enjoys doing up a ladder. You 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. Ninety days before it's due, the owner gets an iPhone notification (optional, switched on in Settings). Thirty days before, another. And again if it slips. On the web, what is due shows on the dashboard. You find out before the client does.

The customer signs on the glass. The moment you hit save, a branded PDF with your logo is ready for the owner or an admin to share or email. The report is done before you have packed the gauges away.

What is on an HVAC service report from Maintivo?

The ready-made HVAC / Air Con service form covers the equipment (asset tag, location, make, model, serial number, system type and visit type), the refrigerant (type, charge in kg, hermetically sealed and labelled, leak detection system fitted, tonnes of CO₂e and next leak check due), condition checks on filters, indoor coil, outdoor coil and condenser, condensate tray, trap and drain, fans and bearings, electrical connections and isolator, controls and thermostat, and pipework and insulation, then performance readings: return, supply and ambient air temperatures, temperature split, running current, suction and discharge pressures, superheat and subcooling. If the system holds an F-gas, the leak-check section appears with the check points, any leak found, its location and repair, gas added or recovered and your F-Gas certificate number; if it does not, that section is hidden so the record cannot contradict itself. There are separate ready-made forms for Split AC / VRF leak checks and chiller service and for fan coil units, AHUs and MVHR. Not sure which leak-check band a system falls into?

Built for rooftops and plant rooms

Signal dies on rooftops, in risers and in ceiling voids. The iPhone app captures the entire job offline, photos and signature included, and uploads it by itself the moment you are back in range. The web app needs a connection and keeps a draft in the browser. Anything still pending shows on your home screen, so a job never quietly disappears.

Two engineers, one standard of report

The classic problem in a small HVAC firm is that two engineers produce two very different write-ups for the same service, and the client notices. A shared template fixes that. Everyone follows the same checks in the same order, so every report that leaves the company looks like it came from the same company.

Your engineers do not see your margins

Engineer seats in Maintivo have no invoices, no pricing and no company settings. They see their jobs and the capture screens, nothing else. Admins get the full dashboard with charged, outstanding and paid. It is not a permissions matrix you have to configure, the screens simply are not there.
