Abstract: A pressure stabilization system for an HVAC device. The pressure stabilization system consists of a monitoring unit attached to the refrigerant and pressure lines of an exterior mounted or connected HVAC unit. Multiple sensors will measure refrigerant levels, unit vibration, ambient temperature, and humidity and provide the collected sensor measurements to a cloud-based platform. The cloud-based platform will provide operational command and control to permit a user to control the unit, add refrigerant, add sealant, and receive recommendations for HVAC operation and maintenance.

Abstract: A monitoring system for apparatus and systems in commercial and residential properties is provided. The monitoring system consists of a head unit and a tail unit, each of which has one or more sensors that measure performance parameters that are important to understanding the performance of the apparatus and system being monitored. As an example, an HVAC system may be monitored to determine when an air filter needs to be changed, or to predict when failure of the HVAC system may be imminent. The sensor array in the head unit and tail unit measure performance and report alerts and historical system performance to users through a mobile app, social media accounts, or any other system for communicating over a wired or wireless network connection.
