What is the brand of your air conditioner at home?

There are three air conditioner in my house, and all of them are Hitachi. I bought the first one more than 4 years ago, and that time the shop promoter recommended me to get the Hitachi's, as he said it's the best selling brand among the air conditioners, also the defect rate is lower. I do not have much problem with the air conditioner so far, I just asked someone to service the air conditioner for me recently, when I got the other two air conditioner, they are Hitachi too. The promoter recommended us to buy that brand too, same reason. I have heard many good comments about Hitachi, perhaps you can survey around or ask the promoters, as they should know which air conditioner gives them more problems.

We are using kalvinator because of its durability and been in the market for decades. So far we have no problem with our unit. I guess it depends on how you use and maintain your air conditioner. Do you use it 24 hours? it cause you a lot if you always change unit so better buy the durable one.
