Air-con Daikin Non-inv System 4, But 1 Unit Becomes Not Cold. Help

[Megadeth 0]

Need some help & advice here on what are the possible causes. Recently, my Daikin System 4 Non-Inverter Air-con of 2 years, 1 of the 4 units becomes not so cold, while the other 3 air-con units are still cold.

Tat not-so-cold unit, the air that is blowing out also seems irregular & uneven, with the air blowing out at both the corners of air outlet.

While the other 3 units, the cold air that blows out are quite even & cold.

Anyone faced this problem before?

I suspect tat 1 unit is faulty or there's some problem with the cold-air pipe leading to that unit. Any advice? Any good air-con service technician to recommend?

Managed to resolve the problem when i engage 1 air-con technician.

Turns out that the metal fin-like grills inside are dirty, so he cleaned & vaccuum the dirt out & voila, the air is cold & the blowing out of the air is even again. He told me i need to service my air-con unit every 4 to 6 months if possible.
