Cloud monitoring
See a fault before you feel it
The Premium and Energy Management packages put sensors on the system: supply and return air temperatures, humidity, CO₂ and power. Readings stream to a dashboard we watch. A rising coil temperature, a blocked drain or a compressor drawing more current than it should is flagged, and often fixed, before the building notices.
6Readings monitored per zone

What a visit includes

The same checklist on every visit, whatever the package, with a written report and photographs afterwards.
