i turn it on when it reaches high degree days... like 90 and above.. other than that, we open the windows on the south side in the morning.. and close them in the afternoon... and then it keeps the house cool.. we alternate windows the following day and create an air flow of cool air where it is needed.. our 2 and 1/2 car garage is attached to the front of the house and it keeps the master br, bath, utility room pretty cool on hot days.. so, we move from room to room as needed... i have a mini office in the garage and go out there on hot days too.. we have a 3rd bathroom there..
