Hi,
Just wondered if you'd had your air con put in yet, i used a company called DMF Plumbing and Heating Solutions the other week, i spoke to someone called Dave, very friendly chap, he came out the next day to quote on 2 units, 1 in my front room and 1 in the main bedroom, he told me where the units would work best, ie not putting it above my front door, he gave me a very reasonable price so i went with him, he didn't want any money up front or anything, just told me to pay him when he'd finished the job and i was happy with it, it only took him a day to install it all, and he gave me a receipt, his number is 666 907 456 if your interested
