Alot of versions out there, MHI not good la, MEQ singaporean favorite la, MEQ is Japan la, MHI got its own factory la. Different aircond shop different story, and your story different too. whistling.gif The only thing i know, MHI is not a newly accomplish company, and it involve in commercial heavy duty aircond system very long time, so residential aircond is just a kacang putih to them, and MHI even exist and support Japan during WW2. More into budget user becos it cheaper than ME?? Hell no and not logic at all. I can also say ME is expensive becos its name. Singapore user prefer MEQ not necessary means MHI quality is inferior compare to ME, just becos ME also produce fridge and other electrical appliance, so its name is more familiar compare to MHI in SG. If you look at MHI brochure, the PCB inside the MHI compressor is comformal coated to prevent corrosion by humidity, ME got or not? No. Support wise, ME service center is at Tun Aminah, MHI is at Johor Jaya, i can't see any lack of support at all.

Anyway, I just purchased a 2HP MHI inverter and 1HP MHI inverter, 1HP i choose premium YL series, which got alot of comfy and extra features compare to my current ME GJ10, and lower consumption too (0.67kW vs 0.8kW), so this new MHI will be my main aircond for my master bedroom since i will use it 10 hours per night everynight. The current ME 1hp will move to guess bedroom for reserve purpose, and the 2hp model i choose YN series, only less comfy airflow function, the rest are same. Outcome, i save almost RM400 compare to ME.

Can u share the prices of all the MHI models U purchased? Your cost saving of rm400 for 3 units?

Oops u r wrong Liao

All Aircons piping size are the same as hosepower required, just internal diameter of thickness are different only, low price and getting thin cover of pipe thickness.

The most important was thickness, due to bend or cut-off can be out of shape, once out of shape when flare and nuts connection join can be leak.

Ya corrected.

Size will affect the performance of cooling and duration time also compressor runs gas.

Only thickness not related to compressor and working, but will affect the condition such as gas leak or explode some way, like wire broken some way.

1.5hp some model still used same size with 1hp and the only 2hp and above is slighly different pipe size, if from 2.5hp and above the copper size is a big gap.

You have to check with the product specs on each models
