Field-Verified Reality
Built for hot attics, rainy roofs, and dead-zone basements.
ACLogics works alongside the tools technicians carry — manifold gauges, multimeters, and manometers. It does not guess or part-swap; it systematically verifies physical readings and builds customer trust.
Read saved diagnostic steps, record checks, and add notes in mechanical rooms and basements.
One invoice for the whole shop. Invite a tech from the office and they are ready on the next call.
On the job
What changes on your next call
Each step tells your tech what to measure, what it should read, and what that rules out.
01
Know what to check next
Tell it the brand, model, error code, and symptom. It tells you the next check and why, so you stop swapping parts on a hunch.
- See what you have ruled out: Causes you have already cleared are marked Ruled Out, so you don't recheck them and can show the customer.
- Fast single-tap entries: Pick from ready-made options without fumbling to type out readings.
- Unstuck on tricky steps: Step Chat clarifies where to probe or how to interpret unusual readings.
02
Snap the nameplate instead of typing it
Snap one photo of any weather-beaten condenser, heat pump, or furnace data plate. ACLogics reads and auto-fills the brand, full model number, serial number, system type, cooling tonnage, and manufacture date for you.
- Know the unit before you open the panel: See the system type and size without decoding the model number yourself.
- Know how old it is: The manufacture date comes from the serial number, so you can talk age with the homeowner.
- No retyping: No mistyped model numbers in a dark attic or in rooftop glare.
03
Continue saved jobs offline
Open the job while online to save it on this device. Then review its steps, record checks, and add notes without a signal. New AI diagnoses, Side Chat, and AI report generation need internet.
- Follow the steps offline: For saved jobs, read steps, record checks, and add notes without a signal.
- Review saved calls: Pull up saved jobs to review how you solved them or reference prior findings.
- Sync after reconnecting: Keep the app open in the same account until saved checks and notes finish syncing.

04
A clear estimate the homeowner understands and approves
Generate a comprehensive, easy-to-read estimate before you pack up. It brings together equipment details, identified issues, and clear repair recommendations so homeowners understand exactly what they're paying for.
- In clear, customer-friendly language: Explain what needs fixing in plain terms, in English, Spanish, French, and more.
- Faster repair approvals: Transparent scopes and clear repair options help homeowners feel confident saying yes on the spot.
- Instant Sharing: Deliver via SMS or email PDF before packing up your gauges.
05
Running with a crew? Bring your whole team on board
Works just as well for full HVAC shops. Connect your trucks, share job history across technicians, and let managers follow diagnostic progress from the team portal.
- Shared job history: See what other techs found on earlier visits so you're never starting from scratch.
- Company-managed access: The office handles invites and setup so techs can focus entirely on the work.
- Uncapped diagnostic access: Unlimited checks, calculators, and estimates for every technician on the crew.
