I don't like temps above 70, and it was 85 here today. The humidity wasn't too bad, though. Before long, we'll be having "air you wear".
I have terrible asthsma type allergies, much aggravated by all that time I spent in the greenhouse with 20,000 blooming petunias, etc, and lots of chemicals.
We also have 2 acres loaded with perennials, bulbs and blooming trees, surrounded on two sides with open fields and woodlands, so I either have the heat or the AC on all the time. The only time the windows are opened is on a sunny winter's day, when the skylights and greenhouse really heat up the house, and there's no pollen in the air.
We get by with a little help from our friends
