Select a common service complaint to trace the dynamic "Preparation → Inspection → Rule Out → Resolution" flow:

Initial Field Complaint:

Indoor blower and outdoor unit running continuously. Supply air is 74°F while return is 76°F (Delta T = 2°F).

1
Step 1: Preparation & Airflow Baseline

Action Required: Check return air filter and blower wheel cleanliness. Measure static pressure across evaporator coil.

Observed Field Reading:

Filter clean, total external static pressure is 0.42 in. w.g. (Normal airflow verified ~400 CFM/ton).

Ruled Out: Airflow Restriction
2
Step 2: Refrigerant Circuit Verification

Action Required: Connect wireless gauges. Measure suction pressure, liquid pressure, superheat, and subcooling.

Observed Field Reading:

Suction pressure = 78 PSI (R-410A, Sat Temp 19°F), Liquid = 245 PSI (Sat Temp 82°F), Superheat = 38°F (High), Subcooling = 2°F (Low).

Confirmed: Low Refrigerant Charge / Suction Line Leak
3
Step 3: Root Cause Isolation

Action Required: Perform ultrasonic / electronic leak detection on indoor flare connections and condenser service valves.

Observed Field Reading:

Pinpoint leak detected at suction line Schrader core fitting.

Confirmed: Defective Valve Core
Verified Solution & Work Order Summary

Replace Schrader valve core with core-removal tool under pressure, recover/evacuate to < 500 microns, weigh in factory charge, verify 10°F subcooling.

Voice-to-Text Intake & Multi-Turn Step Chat

When your hands are covered in coil cleaner or you're balancing on an 8-foot ladder, typing is hazardous. Just tap the microphone and speak naturally.

  • Trained on HVAC Jargon: Understands terms like "TXV hunting", "ECM module", "45 microfarad capacitor", and "refrigerant migration".
  • Context-Aware Follow-Ups: Ask "What should my head pressure be on a 95°F ambient day?" and get calculated targets based on the specific refrigerant and SEER.
  • Real-Time Reasoning Coaching: Junior apprentices learn the thermodynamic "why" behind every step, turning service calls into on-the-job masterclasses.

ACLogics Diagnostic Assistant Carrier 25VNA Heat Pump Session
Technician (Voice):

"Outdoor ambient is 92°F. Suction is 115 PSI and liquid is 340 PSI. Blower running at 1100 CFM."

ACLogics AI:

Based on R-410A saturation:
• Evap Sat Temp = 38.5°F (Normal)
• Liquid Sat Temp = 105.2°F (Subcooling = 13.2°F)
Next Check: Measure suction line pipe temp at service valve to verify if superheat is within the 8–14°F target window.

AI Diagnostic Workflow FAQ

Does ACLogics replace the technician's multimeter and gauges?

No. ACLogics works alongside the technician's physical diagnostic tools. The technician takes real-world electrical, airflow, and refrigeration measurements, and ACLogics performs the thermodynamic reasoning, decision-branching, and rule-out analysis to eliminate false leads.

How many equipment types and brands are supported?

ACLogics supports all residential and commercial system types: standard split ACs, gas and oil furnaces, heat pumps, inverter mini-splits, package rooftop units (RTUs), and hydronic boilers across 200+ major manufacturers.

Can diagnostic histories be shared across our service team?

Yes. Using ACLogics Organization accounts, business owners and service managers can view all team diagnostic sessions, review technician notes, and export standardized customer PDF invoices.
