“

Amazing service from every one, I have only one issue with ecobee thermostat switch, suddenly we got cold air in -25C technician Zi explained to us. ecobee did some upgrade and reseted. Ecobee must inform us about the upgrade. or Airone must inform us about this upgrade and do necessary changes free of charge.<br>Great job guys
