We have one room which is 3 degrees cooler than the rest of our home during the winter. I have closed one small register in the adjacent walk-in-closet, and one small one in the adjacent bathroom to take the edge off in that bedroom. We have an electric HVAC and heat pump with 17 total registers. I understand that closing too many registers can cause damage, but what about 2 out of 17? Thanks for any advice.

Probably won't hurt. Would be better off adding another supply to that room, or may be a return.

Another option is to use a register booster. I used two in a room which is an addition at my house and it made a gigantic difference.

If that one room is 3 degrees cooler than others, I would be looking at return issues, or any leaks through outside wall outlets, along with windows leaking air pass the frames. Even just a section of insulation can cause cool air to radiate off of the drywall.

I have a similar problem. What do you mean elect. not as fussy as bad. Also when checking supply and return temps what am I looking for?
