How to install Sentree

Sentree can be installed on an A/C unit in less than 10 minutes by a certified HVAC technician. No WiFi is required.

How does Sentree work?

Sentree gathers the following A/C performance data minute-by-minute and uploads it to AlertAQ™ for analysis: vapor and liquid line pressure and temperature, calculated superheat and subcooling, average run time, amperage draw, ambient temperature and other information. Whenever there is a problem, assigned users receive an instant alert on their phone via text, email and in-app notification.
