I have a split system in a condo unit that needs replaced. Currently its a national comfort system. http://www.nationalcomfortproducts.com/ncpd1000.php is the link to the new system. I installed one before and Im not very fond of it at all. Just wondering if there is anything like it out there. I cant put a condenser outside. This one sits under the furnace and has a fan that pulls in outside air through the condenser coil and exhausts it back out all through a hole in the outside wall. Carrier, armstrong use to make a unit like that but they dont any more. Can anyone point me to a web sight where i can find something other than a national comfort system?
