@saidsoftly@retro.social I mean, cheap and easy usually wins the game.
For the record, though, I'm not talking about leaving the ductwork exposed. I've never heard of anyone having a mold problem from ducting that's enclosed in either a soffit or within the floor joists as is common here.
Bottom line, though, you completely eliminate energy losses as a consideration when you keep the ducts within the conditioned space. Perhaps because we're all cheapskate Midwesterners, we'd never consider otherwise.
@saidsoftly@retro.social I would say that we're a little more likely to spend a bit more upfront to save long-term in large part because our climate is so extreme.
And it's endlessly humorous to me that what we've been doing as a rule for 50+ years is suddenly being discovered in milder climates.
Like, the framing of this article is genuinely hilarious to me! The house I grew up in was built in the 1930's and used a trunk and branch ducting system.
