Staying cool

So far this season we've not used the A/C and have managed to stay cool with our roof mounted evaporative cooler or swamper cooler. This is a stream of bleed off water running to provide a cleaner water over the pads and prevent mineral build up. Our tree and shrubbery loves it. We'll use it until the dew point is too high for it to work very well then we'll have no choice but to fire up the A/C unit. We will leave for the AZ mountains on the 24th for the major part of 2 months and avoid much use of the A/C.
