Hi Guys, currently my house is running on a Carrier system 3 (Millenium series) bought almost 8 years back. Currently, the one in the materbed room is having some problem. It is not cold.
I just have the thermister replaced, top up the aircon gas about 1 month ago and now it's not cold again. Wondering whether it's the compressor that's leaking. The other 2 rooms a/c are still working fine.
Should I just get someone to replace the whole set to a system 2 as one room hardly use or is it cheaper to just repair the existing problem?
If I am to change the aircon, thinking of getting Toshiba system 2 with 3 ticks. Will there be a substatial saving in electricity bills as I on my 2 aircons at least 8 hours a day?
