The hot weather finally penetrated the house last evening so I went up in the attic and uncovered my whole house fan which had been sealed up in an energy audit. I then went down out of the attic and turned on the fan without any windows open. Lots of noise but the louvers barely lifted up. I thought they were stuck until I went downstairs and opened a couple of windows. The fan then started to act like normal. I guess all I needed was a manometer and I could have checked my air changes while I was at it. I used to be able to do this and the fan would lift up the louvers, so its good indication that my houseis lot tighter these days. I look forward to a full winter with the energy upgrades in place and my new storage which were both put on line mid season.
I did get some wood smoke smell in the house so it looks like my chimney may have been the primary air vent until I opened up a window. I know that the house is on the limit where I need an air to air heat exchanger but havent found a deal on one yet that I like.
I dont use that whole house fan often but its a nice way to get some air movement into the house on a hot night. its also handy when things cool down and dry out to vent the house out. I do have a window AC unit for my bedroom but it rarely gets installed.
