depends a lot on the size of rooms etc and how many BTU you need for a 9000BTU unit you are looking at 290YTL (117 quid)and for a 24000BTU 730 YTL(290 quid) this is for "demir dokum" brand which are fairly good. Advice pay 60 to 70% up front and pay balance on fitting and tell them If the fitting is not top quality they dont get the rest.
