To be fair, we had plenty of that even back in the glory days... but the noise has stayed constant while the signal seems to have dropped off with most topics.
I think that's fair, although it feels like the tone has gotten harsher.
I'm curious, do you think the semi-passive cooling system will still be useful at beginning and end of summer, even if the night get too warm? Savings obviously aren't going to be as attractive as using it all through the summer, but I would hope there are still seasons where the system is worth running.
Definitely. I'm actually already seeing a little of that in late August. Nights are getting down to ~62F, which is managing to cool the house to the high 60s. I'm wondering if I could get a higher-volume fan for the laundry room to increase the air flow... I'm sure that by the end of September we'll have nights in the 50s but days will still often reach the mid-80s. That's when another benefit of having it automated kicks in. If I were just opening a bunch of windows before going to bed, there would be a period of time when the house got too cold at night. With the automated system, when the house gets to 62F it turns the fans off.
Of course, as we get into winter, I pop the laundry room fan out and fill the gap with an insulated pillow of the type they sell for filling swamp cooler vents.
Speaking of swamp coolers... those have historically been fairly effective in Utah, thanks to the dry air. My first house had just a swamp cooler and it was honestly fine. I've actually thought that it might make sense to have all three: passive cooling, swamp cooler and central air. With a smart system deciding which to use when. You don't want to use the swamp cooler a lot on days when the A/C might need to run, because it raises interior humidity, which the A/C then spends a lot of effort extracting. Maybe... have to consider the cost of buying and installing the swamp cooler.
