Question about Mitsubishi MSZ09UN Air Conditioner
Hi the air appears to be cool at first but not enough to cool the room down. The repairmain replaced the flanges and regased today but that has not solved the problem. In fact made no difference. Previously the aircon cooled the room down nice we ran it on 25 deg cel. Now it is set at a max of 16 deg cel.
Split Air Conditioners are not meant to run constantly. so check this first . you may have a faulty component i.e. compressor, condenser, evaporator, or evap fan. Depending on your technician you may have gotten ripped off. You need to find out if he checked the system for refrigerant (gas) leaks. A good way to tell if your ac is leaking is feel the low and high side copper pipe in between the inside and outside units.
the smaller pipe (high side) should be hot be carefull maybe touch it with an ice cube. The Large pipe should be cold but not iced over.
if there is ice on any component you should call a qualified tech. you probably have a leak. you should also clean your air filters which are right above the vents. I am a certified AC mechanic and i have seen this problem. in Iraq because of ambient temperatures being high the systems take alot of abuse and we dont fix them because repair costs exceed replacement costs alot of the time. good luck.
