Also I feellike I have buyers remorse. why
you have top of the line equipment
chances are they pulled the system down and you didnt see them do it. r22 or 410a work pretty much the same and you wouldnt know the differance in cooling
as far as choice some contractors havent started working with 410a yet since it is new and a lot dont feel comfortable working with it. in time we will all be wheather we like it or not. just because you picked the hs26 instead of the hsx doesnt mean your recieved a less then top of the line the only diferance is in the refrigerant and not the ability to cool your house and save you monie on cooling. out of all you quotes no one gave one on a 410a system
