I have just purchased a 2400/sq.ft 3 story townhome in Palm Harbor Fl that is an end unit. The inside was a disaster and I am replacing everything in the unit. The unit was built in 1988 and still has the original A/C unit. I am wanting to purchase and have installed, the most energy efficent heat pump unit possible but after 9 hours of searching around the web, my head now hurts and I am more confused then when I started. I work out of my home and am in the computer field so I have 3 to 4 servers running 24/7 as well as one or two other workstations. For the most part, price isn't a concern as I have budgeted $50k for the remodel which I think will be plenty. I know currently the air handler is in the attic above the thrid floor. Any help, advice or direction that any of you may offer will be greatly appreciated. Thank you in advance.
