Central air unit in attic
I'd want a lot more info.
Did he give you a price? (Putting vents throughout a house that has none has got to be expensive.)
What type of heat do you have now?
I'd get a second and a third professional opinion.
I didn't move into the place until after the systems were installed, so I can't really compare "before" and "after" attic temperatures. I can say that the attic didn't get extremely hot in the summer with the units running in the attic. The exhaust fan didn't kick on too often that I can recall. The attic was a little warmer in the winter, which I attributed to the heating systems and the insulation. Then again, the walls of this house had NO insulation in them and the interior surfaces were plaster, so I felt the cold wind!
The landlord told me it cost about $10,000 for both systems to be installed plus the blown-in insulation (all done by 1 company). The landlord did this to help the house sell...I moved in during July 1999 and they sold the house in September 2000. I hope this information is of use to you. Jim D/Heathsville, VA
Working on a project for client one building has 2 units habitable area is at second floor (first floor is just for access to second level) each unit second floor is 900 SF.
Client likes to have 2 A/C units (one for each unit) my question what models are out there and what are the specs sheets. Engineer needs to calculate loads and also I like to know clearances needed to accommodate unit at attic. Project is new construction. I'm sure clients will look for inexpensive units.
I'm believe client likes to have these units at attic space to safe kept in place.
Thank you for your help.
