We don't have air conditioning in our house. The early heat wave in Wisconsin has been exceptional with 90+ temperatures. The house has warmed to an uncomfortable level for sleeping so we slept in the RV last night with the air conditioning running. It was great.
Today I ran the air conditioner fan on high and had my wife holding a shop vac hose in the blower mode over a light fixture hole. It was an attempt to pressurize the ceiling area while I used soap water to check for leaks on the roof. I did not find any. I think I need more pressure. Last night's storms showed me I still have a leak. It was too hot to do much else.
