Bought a Comfee 2.6kw air con unit for the bedroom - excellent price when you consider we recently had a quote from a professional to supply & install at £1,300 plus vat - not too bad, BUT, he wanted another £1,400 to install a second unit in the room directly above - 2 v simple installs - 1 days work and the units and parts would be say a total of £1,300 max so £1,400 for a days work - where is the economy of scale and an honest days work for a fair price? We are experienced DIY'ers but have never done air con before, hubby has limited car air con experience and electric experience so once we found the easy install units at Cooleasy, we thought we would try one unit, the worst that could happen is we have to pay to have it re-gassed. The instructions from the manufacturer are both wrong (in parts) and hard to understand ...however, with some v prompt responses to queries from various staff at Cooleasy (Mike & an installer) we did it, it works great & the unit is v quiet and works well. We are so happy I just ordered another 3.5kw unit for the bedroom above and I have no doubt that will be easier & much quicker now we have done one. Probably too difficult for someone with no DIY experience but otherwise, doable. Thanks guys
