Yesterday's 107^o in Houston and 108^o in San Antonio are oppressive due to high humidity usually found in those cities.

It was 104^o here in the sagebrush desert of Nevada. Not that bad because humidity is under 10% and a swamp cooler works great under these conditions.

Hint: have a pro clean and check the swamp cooler before the hot weather hits, just after the last frost day.

Also have a pro drain the water line and put it to rest before winter.
