This year I kept the AC off until Aug 1. I am 10 min walk from the beach though.
Heat is a single gas wall heater, no ducts except for exhaust, AC is two window units.
Lately I have been running the bedroom AC all night, this morning I woke up to a very dry 64 degree bedroom, it was wonderful.
I like turning off and then lighting the heater pilot light to mark the change of seasons. I also move the water heater to the lowest setting in summer and almost to the max in winter.
My office suite has huge glass windows that don’t open, and my electric bill for it rises to $350 in the summer compared to $100 in the spring.
