I am buying a home in the Philadelphia suburbs that was constructed in the 20's. There is no original duct work in the home, it has radiator heat (which I like), and in-wall AC units in some of the rooms with condensers outside. Not every room is cooled though, which I expect will be problematic in the summer.
The units are ugly as sin in the interior of the home, but do not show, thankfully, through the wall on the outside. The home is registered as "central air" in the municipal records, but I always understood central air to be a traditional duct cooling system. I have not been able to find info on these wall units online that explains the installation methods - can someone help reconcile the use of the term "central ac" with these units?
Can these types of units be replaced with more modern/sleeker looking units, depending on fit? (See pic)
What would be the first step towards determining whether traditional system or high velocity would be suitable for the home? I do not have any storage space on the third floor finished attic - is storage a requirement for either system type?
Thanks for your help.
