Just an quickie on the house’s performance.
Last night the house was 69 degrees. I use a laser thermometer gun to check temperatures. The temps varied between 69.0 to 69.5. at 11:00 before I went to bed. We left two windows in vent mode, one in the Kitchen and one in the bedroom.
At 7:30 in the morning the house lost about 2 degrees overnight to 67.0 to 67.5. The outside air temperature was 43, but more interesting the hard services, the deck, and siding were at 32 degrees.
At this point there is no sense of a draft. Again waiting for winter.
