Installers were friendly, courteous, knowledgeable, and hard working! Despite a lot of interference and obstacles, the installers cleaned out fiberglass insulation and stuff and did a great job, and the clean-up was impressive.
The installers found some significant sources of air in-leakage and were both innovative and effective in implementing fixes.
The weather sealing of the basement door provided a fix that will significantly cut down on heat loss, as well as it is easily removable and re-installable for access to the basement door.
I'm sure the hard work of these installers will result in much lower energy bills.
waiting to hear that the part tech suggested is FREE.
