A heat pump system randomly freezes every 4-5 days despite normal refrigerant charge and recent component replacements, and the technician cannot diagnose the root cause.

No diagnostic tools or software are available to capture intermittent fault data over multiple days (e.g., temperature and pressure logs, equipment cycling patterns) to identify why the system freezes periodically.

Implied Software Gaps

An affordable, easy-to-install monitoring device that logs HVAC system data over days or weeks to capture intermittent freeze events.

App Concept

HVAC FreezeWatch

A smart diagnostic monitoring device that connects to the HVAC system to continuously log refrigerant pressures, temperatures, airflow, and equipment cycling. When an intermittent freeze condition occurs, it captures the data leading up to the event and alerts the technician with a detailed diagnostic report.

Key Features

Continuous monitoring of suction/liquid line temperatures and pressures
Automated detection of freezing events and generation of diagnostic timeline
Cloud dashboard with historical data and trend analysis
Alerts sent to technician and homeowner via mobile app

Target Users: HVAC technicians and service companies diagnosing intermittent system performance issues in residential and light commercial heat pump systems.

Revenue Model: $199 per device (one-time hardware) + $9.99/mo subscription for cloud data storage and advanced analytics, or $49/mo rental with device included.
