Hi all, I read back some pages of this discussion but am still unclear what is the better fan option to go for. My current KDK AC type installed 10 years ago already started getting noisy 2 years back and now getting increasingly louder so I think it's time to change. I am a bit undecided between AC and DC. I like to stick to KDK as from what I've read so far, seems like other brands are a bit so so. My main concern is whether 10 years down the line will I face the same noisy issue. I have consulted a handyman before who told me that it's pointless to repair my current noisy fan and should just get a new fan. 

My budget is between 300-500. Any recommendations?
