My air conditioning has stopped working and i wonder if it has something to do with my emerson thermostat. the thermostat is reading ''system on +2''. the unit usually reads ''system on'. could this be an issue?

“System On” indicates when heating or cooling stage is energized. “System On +2” indicates when a second stage is energized. This means that the thermostat is sending the correct signal to your AC equipment to run but your unit is not responding on the call of the thermostat, Most of the case this is a system issue not the thermostat, you need to contact your installer to resolve the problem.
