A customer of mine is building an addition on to her maids apartment for a rare 18 year old parrot. She is spending over 150k on this project. I have calculated the btu gain to be 3 ton. My question is... Has anyone ever encountered cooling and heating a giant bird house of all glass? I am leaning towards installing an air handler outside the room and ducting it in. Is there special equipment designed for such application? If so where do I find it? However a ductless split would be great if the bird wouldn't tear it up! Please advise! She is very attached to this bird and I would not want anything to happen to it as well. Of course whatever goes in.. I think I need to make some exclusions in my actuall contract before proceeding. Thanks!
