I hear you on the indoor humidity—mine’s a 1955 ranch, and even after I swapped out all the old windows, I still get some icing if I’m not careful. I tried running a fan during showers, but like you said, it’s the little things that add up: boiling pasta, drying towels over radiators, even just having people over. The humidity creeps up before you know it. Cracking a window helps here too, though my kids grumble. It’s not perfect, but it beats chipping ice at 6 a.m.
- Noticed the same thing here—humidity spikes fast, even with a new HRV running.
- I tried a hygrometer in a few rooms and was surprised how much it varies.
- Have you checked if your attic insulation or vapor barrier is up to date? I read that can make a difference, but I’m not sure how much in an older place…
