"I turn off the AC or heat, due to fan noise and circulating air, when I listen."
I guess many of us do. I do, but there is that other problem, "Is your refrigerator running?" which despite the old joke many of us do wish it would runaway considering the disturbing noise these modern refrigerators make. Smaller homes where listening spaces are in close proximity to kitchen is real concern, for unlike AC/heat shut off at thermostat, shutting off a refrigerator full of food invites real risks.
