"What should I test next?"
That's ACLogics. Guided troubleshooting that turns a symptom into an ordered list of candidate causes, checks, and confirmations — and teaches junior techs the reasoning as they go.
Comparison Guide
There are more good HVAC apps than ever, and they don't all solve the same problem. Some are equipment-data libraries. Some read your probes. Some document the job. ACLogics is a diagnostic copilot: it helps a technician standing at a broken system figure out what to check next, and why. Here's an honest look at how that compares to the other tools your techs might carry.

The Short Version
That's ACLogics. Guided troubleshooting that turns a symptom into an ordered list of candidate causes, checks, and confirmations — and teaches junior techs the reasoning as they go.
That's Bluon's home turf — a huge equipment, manuals, and parts database with AI support on top, plus deep integrations with ServiceTitan, Housecall Pro, and BuildOps.
MeasureQuick and Fieldpiece Job Link shine here — they read Bluetooth instruments in real time and score system performance from live measurements.
XOi focuses on photo/video documentation and AI work summaries for commercial workflows. ACLogics covers documentation too, with customer-ready PDF reports built from the diagnosis itself.

Tool by Tool
Bluon is the biggest name on this list, and it earns it as an HVAC data platform: millions of model numbers, OEM manuals, wiring diagrams, bills of materials, and part cross-references, with the MasterMechanic AI and a live support line staffed by HVAC veterans on top. It also plugs into ServiceTitan, Housecall Pro, and BuildOps, which makes it a natural add-on for shops already living in those systems.
The honest difference: Bluon starts from the equipment; ACLogics starts from the symptom. When your problem is "I need the manual, the right part number, and a compatible replacement," Bluon is excellent. When your problem is "my second-year tech is staring at a dead condenser and doesn't know what to test next," a parts database doesn't walk them through it — a guided diagnostic workflow does. Bluon's real strength is also a library, and libraries are built to be searched, not walked through — your tech still has to know what to look up, then read it off a phone screen in a hot attic. ACLogics is built the other direction: it keeps a structured job state (candidates confirmed, ruled out, pending), asks for your actual readings, and produces a customer-ready report at the end, so the tech is never stuck flipping through a manual with one hand while holding a flashlight with the other. Plenty of shops could reasonably run both.
Carrier's free technician app is genuinely useful — fault-code lookup, guided troubleshooting, an AI assistant in beta, NFC connections to some newer boards, and a parts-center locator. If you install and service a lot of Carrier-family equipment, your techs should have it.
Its boundary is built in: it exists to support Carrier equipment. Most service companies run calls on whatever is in the ground — a 15-year-old Goodman in the morning, a Trane in the afternoon. ACLogics is brand-neutral by design and diagnoses by symptom and system type across 200+ brands, so the same workflow habit applies to every call, not just the ones that match the nameplate. The same trade-off applies to other OEM apps (Daikin, Trane, Mitsubishi all have their own).
MeasureQuick is the measurement-and-commissioning standard: it connects to 80+ Bluetooth probes across 17+ tool brands, scores refrigerant charge, airflow, and combustion in real time, and its Premier tier ($49/user/month) adds AI Assist and cloud dashboards. For verifying that a system is running right, it's the deepest tool here.
The difference is the starting point. MeasureQuick is strongest once probes are on a running system; ACLogics is strongest when the system won't run and someone has to reason from symptoms — no special hardware required, readings typed or spoken in from whatever meter is on the truck. MeasureQuick also assumes a level of measurement fluency that junior techs are still building; ACLogics is built to coach exactly those techs. Many crews would benefit from both: ACLogics to find the fault, MeasureQuick to verify the fix.
XOi is field-service documentation and asset intelligence, aimed mostly at commercial contractors: photo/video capture of every job, dataplate recognition, AI work summaries, a knowledge hub, and virtual mentor sessions. It integrates with FSM suites like ServiceTitan and BuildOps and is priced by sales quote.
XOi answers "prove what happened on this job." ACLogics answers "figure out this job, faster." There's overlap — both capture photos and produce professional job records — but ACLogics' report falls out of the diagnostic workflow itself (symptom, readings, confirmed root cause), is generated in the customer's language, and comes with transparent per-tech pricing a small residential shop can adopt without a sales call.
Job Link is the companion app for Fieldpiece's wireless probes and manifolds: live readings within 1,000 feet, automatic superheat/subcool calculations, and instant measurement reports. The app is free; the value (and cost) is in the hardware ecosystem.
It's an instrument display, not a diagnostician — it shows you the numbers, but it doesn't tell you which numbers to go get, or what to conclude when they conflict. ACLogics is tool-brand agnostic and sits one level up: it decides what's worth measuring and interprets the result in context. If your shop runs Fieldpiece gear, the two coexist naturally.
Interplay Learning tackles the same industry problem we care most about — the experience gap — but in the classroom: 500+ hours of courses and VR/3D simulations where techs can safely practice on virtual equipment. For structured onboarding programs, it's a strong choice.
ACLogics does its training on live jobs. Every real call becomes a coached rep: the app explains why each check matters while the tech does billable work, and the shop's shared history shows leads exactly how each tech reasons. Simulation builds foundations; a copilot builds judgment where it's tested — on the roof, with the customer waiting. They're complements more than competitors.
Straight Answers
We built ACLogics inside a working DFW service company because the hardest problem we had wasn't finding parts or reading probes — it was getting senior-tech judgment to the person actually standing at the unit. If that's your problem too, we'd love to show you how it works.
