Lots of windows with southwest exposure, but at this time of year the sun goes over the house. Only late in day do we get some sun through west side windows. Put it on yesterday at 3pm. Inside temp was 80f. By 9pm, room was only down to 76f. Left it on all night. Room temp is 71; same as outside. Meanwhile ouu master bed unit got temp down to 64f. I took the IR gun to both and they are both blowing out 58f air.
Good advice from Brian, definitely set it lower and run constantly. 58 degree air discharge is great. You will stay ahead if you do as Brian suggested. My floor unit has been stellar this year, house hasn’t been above 71. One bedroom window unit and one floor unit have kept the house at 70/71. We haven’t even used the lower floor wall unit in AC only dehumidifier. Despite earlier suppositions the floor unit isn’t loud and it’s efficient. My electric bill with the pool pump and AC only went up 33 dollars from June 8th to July 8th and I used 25% less electricity than last year. Last year I ran two floor units and 3 windows. Using fans on the ceiling and one floor unit I finally figured out how to cool my house at 1750 sq ft the most efficient. Helps being home all the time to figure it out. I even shut the floor unit off at night and just run one window unit and fans.
