I have a few baseboard floor registers just like in the picture I have attached. They are located in my living room, under a window and are about 2 feet apart. I need to move a few chairs in front of them and had a few questions. How much will putting furniture in front of them affect the AC and heating performance? Is there a rule as far as clearance? I think I can get them so only about half the grill is blocked at all by the chairs. Thanks
