We just had a 3 ton AC/Furnace replaced.

After the install the air flow out of the vents "seems" lower than before and I do not get the "cool air" feeling as i walk around the house. However it seems to be lowering the air temperature.

We ordered a 3.5 (3 1/2) ton system since I wanted to get a stronger system to reach some of the further parts of the house. However "seems" the opposite occurred.

I had installer come out and check things out. The blower speed is set to high and the temperature drop is 22 degrees. The manufacturer is Carrier. Air flow at all vents is between 300 and 500 CFM.

(1) Can one determine if this is a 3 1/2 ton system from the model #s.
(2) Would mixing Performance with Comfort be an issue.
