well, the guy who installed our air-conditioning, took a look at it today. He found the culprit!!!: mother nature.
Paula was living next-door when Iwe moved into the house. Just before she moved out, she planted two cottonwood trees I have been without air conditioning for nine years and now that I am homebound so I’m not outside very much.
At least it’s comfortable in my house right now even though it’s 89° !
