Having a Mitsubishi unit (Mr. Slim) for about 7-8yrs, can’t remember the model, whether invert or not? Only have 2 blowers one in MBR 1.5HP 12K BTU (size of 2 bedrooms) and one more in other room, 9K BTU. MBR has been leaking in recent months. Did 2 time complete chemical washing this year alone, vacuuming at the drainage pipe, problem solve for a while then back again.
Just did a chemical wash last night, technician inspected the compressor, top up gas and so on. Later when trial run, suspect compressor not running, pour water over compressor and observe “smoke” rising, saying overheating, waited a while and continue to pour water till cool further and blower starting to blow cool air. Problem solved and technician left. Later on the aircon again and no cool air at all, only blowing wind but amount of wind did improve after the chemical wash.
So guys, any advice on what is happening?
Shall proceed with repair or simply replace the complete system?
Need a system 2 only, with usage mainly in MBR (size of 2 bedroom), any recommendation?
Due to concealed piping and trunking, prefer to reuse existing? Any comments?
