Closing Off Part of the House and HVACClosing Off Part of the House To Save Energy on HVAC - I have a Heil gas/electric package unit in my home. I, particularly, want to know, if I can close off a section to save on heating. Heating dealers have not been helpful as they hedge on whether and how this can be done with the system still running at its most efficiency.

I have closed doors to seal off the area. Then closed floor registers. Should I also close air return in that area? I just read this should not be done at all as it decreases unit efficiency? Will you please advise. I am thinking of closing off part of the house to save energy on HVAC. Thank you. (more…)
