I'd normally talk about a heat wave in the "It's Hot Out" thread, but I want to focus on the amazing Mitsubishi mini-split heating/cooling system. It's been in the 90's every day since Friday, with sweltering humidity, but this one unit - on a low setting - keeps the entire main living space like this and dry. And it's completely silent; you have to stand right next to it, with no TVs or music playing, in order to hear the sound of air moving. The 2nd unit in the master bedroom easily gets that area down to 67, on it's lowest setting. And by low setting, I don't mean lowest temp, I mean lowest blower fan. The 2 condenser fan units are under the back porch. Someone had warned me that I'd be hearing them humming all summer; but again, all you can hear is the fan slowly moving, and an almost imperceptible hum. I guess it helps that all the walls and roof are a foot thick of solid insulation, plus the Anderson windows. For the last 20 years, we've mostly opted to sweat, instead of enduring the brain-rattling hum of the window air conditioners.
