Contributors to this forum know their stuff, as evidenced by all the high quality information I've been reading. I'd be very appreciative if someone can assist me with my question:
I've purchased a townhome on Capitol Hill in Washington DC. It's from around 1908. It's got no A/C, but does have radiator heat. There are currently no metal ducts for an A/C unit.
I've had a home inspection done and the inspector recommended high velocity A/C units. He noted Space Pak etc. The building needs a new roof, so I was thinking about doing the A/C at the same time and putting A/C on the new roof. My question is this: conventional or high velocity?
High velocity Pros: 2 1/2" tubes versus 8"x4" metal grates in the walls for a conventional unit. Also, high velocity is less visible. Space is a premium, and I'd be looking to rent the basement out at some point, it has 7' ceilings with exposed beams, so high velocity would be easier to snake in between the joists when I drywall over them to finish the ceiling. Does high velocity last as long as a conventional unit?
Conventional Pros: More efficient and cheaper? Longer lasting? Less expensive?
Any insight into this is appreciated. Including brands and even contractors in the area if applicable. thanks and keep up the great work
