I own a printing press in mancheswar(Bhubaneswar) where I have two offset machine which needs ac for cooling its motor as after a certain printing it becomes hot .
From the last two years I am using haier 2 ton window ac for my production room and till date I have no issues with it it has an amazing compressor which really is tough and for a unit its too good because usage is very high .
Near about 8 hours a day. With one hour break in between still it is so tough to manage it. The sound is also manageable and is a good ac according to me for trusting upon. Cooling is just sensational of course which makes my production room chilled within 20 minutes.
