i'm currently about to start calling some local guys to come out and give me some quotes regarding having a ducted air conditioning system installed... I have looked through whirlpool and a few other forums for info but would if possible like some info from people i trust a tad bit more than whirlpool members. mainly considering daikan or fujitsu as for such an expensive addition to the house i would rather spend the money to make sure i've got a worth-while unit and looking to try and keep it around the 10k mark but preferably less of course (my house is that of a average size housing commission style house.) have any of you had any experience or heard horror stories of either brand? are there any other brands i should be considering? is there anything i should be on the look-out for? on a slightly related note - it being 10-15 years since being done should i look into having my roof insulation replaced beforehand?
