I have had three in-home quotes for a new system. All three have quoted the same size system based on installed equipment. None of them did any kind of load calculations. Sears collected some of the data, but the rep's computer was in the shop.
So after reading this forum, I saw the need to do the load calc myself. Much to my surprise, the load calc results came is far lower then expected. With single pane glass windows, it came in at 2 tons. With double pane glass windows it came in with 1.5 tons. So how can the installed system be so over size?
I would really like to get the right kind of system installed, and finding someone that will do it right seams to be hard here in Houston. Any comments on where I can find someone here in Houston would be great. Or anything else I can do to insure i get the proper system.
