hi all, need some advice here on identifying my problem.

I have a mitsubishi electric inverter 3 system in my house. 9k BTU each. when all aircons are on, only the master bedroom is cold and the rest of the rooms alternate between moderately cold and warm. I just had normal cleaning/ chemical wash and gas pumped in recently so could it be a thermostat prob or anything wrong with the PCB board?

Advice greatly appreciated.
