chiller due for servicing?

[dnsfpl]

my chiller(cl 650) is getting noisier, and the time taken to cool the water down is longer than before

is it due for servicing? how much does it cost? any lobang?

thanks

anyone knows what is the cost to get the fan repair/replace?

thanks

You can look for Derek 97979910. He just did a servicing for my Teco few days back. Good service...
