What is wrong with my orchid? The leaves are turning yellow

[Waterdog111]

I just have to say this,although I haven’t even read all about the Phals. They are just about all you can buy here about at the HEB store. I bought a small to average size one with nice blooms to take to my sister(as she’s in a nurseing home) I put it in the window there, and the lady in the bed next to her loved to keep that room as cold as she could, and that window sill sit right above that air conditioner and it made me wish I had a coat on(and I like cold)well that little orchid kept its blooms 3 1/2 to 4 months and then put out another spike and bloomed again. What I’m trying to say is I don’t think they have to be too warm. That little orchid is still alive and with blooms over 6 months. It only get a watering about every two to three weeks.
