I recently purchased a 2 story aprox. 2600 sq ft home with an ac unit for downstairs and a seperate unit for upstairs. Upstairs we have the master bedroom, master bath, walkin closet, full guest bath, 3 other bedrooms and a bonus room over the garage. The bonus room and master bedroom both have vaulted ceilings.
Here recently the weather in TN has really started heating up so we finally turned the ac on and have discovered that there is little to no air flow from any of the vents. Called the home warranty company, they sent out a tech, and he instantly told me I needed a bigger unit. He then threw out a best guess on price for total replacement and left. (Needless to say not very impressed). I then hired another company to come out and look. This tech was much more professional and told me that the duct work needed to be cleaned up and resealed, and the unit was low on freon. I sent this report into the warranty company so they sent out a 3rd tech. This tech said the unit was too small and basically even in ideal conditions it would never work because there were too many registers for the unit (10 total upstairs). He told me that I should add another unit for half the rooms and the master and let the current unit supply the bonus room and other bedrooms.
I am just looking for a little guidance. Not really sure what to do at this point has we have had basically 3 different suggestions. Any ideas?
