I have a one room metal building that measures 25' wide 40' deep 20' ceiling.
Metal purlin r-panel style construction
all surfaces have blown in foam with fiber material blown into the foam. I think it's R-7. Not bad temp control with no AC is ok if only in peak season.
Location New Orleans
One room no windows one door
use as office no kitchen
i do have gas if needed.
I've used this site to learn about what I may need and this is what I've come up with.
5ton 2stage 16seer heat pump with variable speed. Thinking Infinity or Evolution. It has zones for future use.
Would someone like to advise me on what to get? Thanks
