A/C Monitoring System

Sentree provides 24/7 real-time remote monitoring of residential air conditioning systems to track A/C health. When unusual activity occurs, Sentree sends alerts to HVAC contractors so they can proactively diagnose the issue and dispatch the right service to the property.

Sentree can help HVAC contractors increase maintenance revenue, reduce truck rolls, and boost customer retention.
