Went out to a house where they added a garage and then off the garage a commercial style kitchen for there cattering services. They have floor heat and now want a/c. The kitchen has a couple stoves/ovens and exhaust fans. The kitchen is about 500 sq. ft. and then a 80 sq. ft storage area, 120 sq. ft office, 80 sq. ft mechanical rm. Thought about putting a air handler in mech. rm and running ducts above drop ceiling to different rooms and running wild return above drop ceiling with egg crate returns in office and kitchen. What do you think? Any better ideas.
