Thanks for the 1rst answer regarding central air. We have approximately 630 square feet of living space on each of 3 floors. the central unit is a Heil, 2.5 ton. there are 5 vents on 2nd floor (2 bedrooms and bath), as well as a return and thermstat (next to return). There are 4 vents in 2 large rooms on 1rst floor. Also 2 vents in basement. I was was told by another that we shouldnt try to cool basement so I just closed them.
After tracking the temp. 4 past 3 days we found that , if the thermstat. is set for 67, the 1rst floor temp goes up to 75-76. If thermstat. set for 70, 1rst floor goes 76-78 degrees. On the heatwave days the 1rst floor temp. reached 85 degrees.
The contractor said he will replace 2.5.unit with a 3 ton, but I'm worried that we will have same problem, and there is no room for more vents. Would putting in a Mitsubishi unit for the 1rst floor be better? Some one mentioned a damper; what is that exactly? Any recomendations? Thanks much.
