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.

10+ Supported Brands

Carrier, Trane, Lennox, Daikin, Goodman, Rheem, York, Mitsubishi, and more.

100% Offline Local SQLite Engine

Read, update, and complete cached diagnositic sessions in signal-free mechanical rooms.

Core Product Matrix

The 5 Pillars of ACLogics

Every feature is backed by real on-device code, thermodynamic logic, and verified field workflows.

Pillar 01

AI Decision Tree Guided Diagnosis

Stop blindly guessing faults or swapping boards. Based on brand, model, error code, and symptom, ACLogics generates an adaptive decision tree with dynamic "Preparation → Verification → Conclusion" state-machine branching.

Dynamic Rule-Out: Automatically marks impossible branches as Ruled Out and focuses on the high-probability fault.
Hands-Free Voice Intake: Dictate measurements in gloves with speech-to-text tuned to HVAC terminology.
Step Chat Coaching: Ask follow-up questions to understand the exact thermodynamic "why" on every call.

Step 2: Capacitance Test Measure Capacitance Across Herm & C Terminals Reading: 0 MFD (Below Spec) → Confirmed Electrical Failure

Root Cause & Recommended Action Replace Dual Run Capacitor (Restore Compressor Startup)

ACLogics symptom intake screen with the plain-English complaint "Some rooms cold air, some rooms warm air" typed in, a voice dictation button, and an Analyze Symptom action.

Guided diagnosis step asking "What did you find?" with two branches — filter heavily soiled goes to the fix, filter clean advances to inspecting the evaporator coil.

Diagnosis summary marking obstructed airflow and low refrigerant charge as "No issue found" with reasons, and flagging a liquid line restriction as the action needed.

Pillar 02

Point-and-Shoot Nameplate Scanner

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.

Instant Equipment & Tonnage Decoding: Auto-identifies system type (Split Heat Pump), capacity (024 = 2.0 Tons / 24,000 BTU/hr), and SEER rating.
Serial Age & Warranty: Parses OEM serial prefix logic to calculate equipment age and warranty eligibility.
Zero Manual Typing: Eliminates mistyped model characters in dark attics and rooftop sun-glare.

Pillar 03

Offline Field Execution & Cached Job Access

Step into steel commercial plant rooms or concrete basements with zero signal. Once generated online, your guided diagnostic steps, error code databases, and calculators are cached in local SQLite for seamless offline execution.

Read & Follow Offline: Review diagnostic steps, record meter readings, and log component tests with zero signal.
Fast Cached Search & Pinned Jobs: Instantly filter your active, bookmarked, and locally cached calls on-site in milliseconds.
Automatic Cloud Sync: All offline measurements, notes, and photos sync bidirectionally as soon as your device reconnects.
