TunePro HVAC/R

TunePro grades your superheat and subcooling, ranks what the numbers point to, and shows the case for and against every call. The call stays yours. When the readings can't separate two causes, it says so, and names the one measurement that would settle it. There is no percentage confidence anywhere in the app, because the engine doesn't compute one. WHAT IT DOES • Grades superheat and subcooling for comfort cooling and heat pumps. On a TXV, subcooling judges the charge. On a fixed orifice, the target superheat is computed from your return air temperature, humidity and outdoor temperature — the way a charging chart does it — and until those readings are in, it won't pretend to grade the charge. For refrigeration, the PT calculator and live probe readings still work. • Ranks the likely faults. Each one shows what points to it, what argues against it, and what to check next, with every check tagged by how much work it is. The ten-minute check comes before the two-hour one. • Pressure–temperature calculator covering 30 refrigerants — R-410A, R-32, R-454B, R-22, R-404A, R-448A, R-449A, R-134a, R-290 and R-744 among them — each with its safety class and a facts card. The R-744 card shows its critical point and the band where venting makes dry ice. • Saves every reading to a history on the phone. Each one records whether its numbers came from an instrument this app has validated — model and firmware, not just paired — or were typed in by hand, so an old reading still says how much to trust it. READS YOUR PROBES Five brands connect over Bluetooth: Fieldpiece, Testo, Parker Sporlan, Yellow Jacket and NAVAC. Readings stream live while the system settles, and a dropped link is retried on its own. A Testo clamp and a Fieldpiece manifold on the same call land in one set of readings on one screen. No probes? Type the numbers in — everything works the same. OFFLINE, NO ACCOUNT Measuring, grading, diagnosing, the PT calculator and the reading history all run on the phone. No sign-in, no signal, no card. Nothing on that path waits on a server. FOR A CREW Sign in and your company's sites, equipment records, readings and photos are shared across every truck — and the office sees the same records in the TunePro web app. Every reading carries who saved it and when, and the records belong to the company, not to whichever phone took them. Work done out of signal queues on the phone and syncs when you're back in coverage. When the job is done, send the customer a plain-language report — a link, or an email — that stays frozen exactly as you sent it. Paid plans cover the crew side — cloud sync and company-branded reports, priced per seat — and are bought and managed in the TunePro web app. This app does not take payment.
