Zquel Monitor

Bridging the gap between homeowner and HVAC Technician.

The Zquel Monitor

The Zquel Monitor is a WiFi connected device that calculates the efficiency of your system as well as the IAQ.

System Efficiency

The Monitor uses Predictive Maintenance technology to save the homeowner money by alerting them when there is a problem with their HVAC system. It gives the homeowner a way to monitor efficiency over the life of the system and can help lower energy use and its asssociated costs.

Indoor Air Quality

The Monitor protects your home by monitoring for specific Volatile Organic Compounds (VOCs). The homeowner can take actions such as replacing their ventilation system or simply changing their air filters before problems have a chance to arise.
