What is the minimum distance between 2 A/C registers location on the ceiling? I've a scoffed ceiling, and there are recess cans near the corners. Because of that my builder moved the A/C registers closer - approx. 2 to 2 1/2 feet apart.
I think they are too close, but builder says it is okay. This master bedroom size is 15x17 ft.
Any suggestion is appreciated.
2) This is a 2 story home and we have 2 zone system one for each floor. There are 2 return registers located on the 1st floor only. None on the second floor. Builder says it is okay. But, I'm not sure.
What are the recommended number of return registers?
