Questions about the diagnostic steps.
How does a diagnosis start in ACLogics?
You describe the symptom, error code or readings. ACLogics lists the possible causes in check order and walks you through each one. When a reading clears a cause, it records why and moves on. The checks you made become the service report.
How are the causes ordered?
Quick, easy checks come first. Among checks that take similar effort, the most likely cause comes first. That is why breakers and disconnects come before a capacitor test.
Does it work without internet?
Starting a new diagnosis needs a connection. After that, you can open saved jobs, follow the steps and record checks offline. Side Chat and new AI reports need internet. What works offline
Do I need extra probes or sensors?
No. Use the meter and gauges you already carry and enter the readings. The app runs on iPhone, iPad and Android.
Which equipment does it cover?
Residential and light commercial: air conditioners, heat pumps, furnaces, mini-splits, packaged units and boilers. Diagnosis starts from how the system is behaving, so it is not limited to a model list. On anything unusual it tells you to escalate instead of guessing. See a commercial RTU call
What if the app is wrong?
Trust your meter. If a reading contradicts the step, choose the answer that says so. The app marks that cause ruled out, with the reason, and moves to the next one.
