The technician comes built in.

AI diagnostics watch your machine continuously. When something drifts, the app names the cause in plain language and walks you through the fix — before it ruins a weekend on the water.

Air tightness

Duct leaks caught before they cost you amp-hours.

Water flow

Clogged strainer or tired pump — flagged with the fix.

Condenser efficiency

Heat-exchange trends watched; cleaning called at the right time.

Dirty filter

Airflow-based detection — no guessing, no schedules.
