I am wondering what size is this evaporator coil.

Also how many cfm's should it be moving?

Is the blower one speed or can it be set from low to high?

How many CFM's is this unit capable of?

Can the blower be adjusted from low to med to high/

A 2.5 ton system would require 1000 cfm of air. Most all furnaces are equipped with at least a 3 ton blower. Carriers have multi-speed blowers and yes there is high, medium, and low. High speed is going to be a black wire of the blower motor. You may want to call a qualified person to verify speed selection is to your satisfaction

I switched blower motor to Medium Low to see if it makes a difference in the cooling in the house.

I have a 1700 square foot house.

Will changing the blower setting affect how much freon there needs to be?
