That time I learned the hard way that “dry heat” isn’t always better

That hum from the HRV can definitely get under your skin, especially if you’re used to the old-school “open a window and hope for the best” method. I’ve worked in a bunch of 70s houses like yours, and honestly, leaky windows can make your energy bills do some wild things - hot air just flying out in winter, AC working overtime in summer. Once you tighten things up and add an HRV, you usually see the bills drop a bit, but it’s not always dramatic. The real win is the air quality - no more mystery condensation on the windows or that weird musty smell after a week of rain.

About the noise: some folks toss a thick rug or hang heavier curtains to muffle it a bit. Not high tech, but it helps. If your HRV doesn’t have a sleep mode, you could try running it on low overnight or even putting it on a cheap plug-in timer - just don’t turn it off for too long or you’ll end up with stale air and maybe even mold if your place is sealed up tight.

Honestly, I kinda miss being able to just crack a window too... but then I remember the ice buildup on my sills every January and I get over it pretty quick.

That’s funny, because when I first moved into my place, I was all about the “dry heat” everyone raves about. Figured it’d be a nice change from the damp, drafty apartment I used to rent. Turns out, cranking up the heat in a sealed-up house just made my skin feel like sandpaper and my nose was basically a desert. I tried leaving the HRV on full blast thinking it’d help balance things out, but that just made the hum louder and didn’t do much for the dryness.

Ended up buying one of those cheap hygrometers and realized my humidity was barely scraping 20% most days in winter. Tossed a couple of humidifiers around and things got better, but man, it’s a weird trade-off - better air quality but you have to babysit your house so it doesn’t turn into either a swamp or a dust bowl.

I do miss just opening a window for some fresh air, but yeah... not enough to deal with frost on the inside of the glass again.

Totally get where you’re coming from. My place is a 70s split-level and the first winter I spent here, I had the same “dry heat” shock. Here’s what I ended up doing, step by step:

1. Got a hygrometer - just like you. Eye-opener.
2. Put a small humidifier in the bedroom and a bigger one in the living room. Had to refill them way more often than I thought.
3. Figured out that leaving the bathroom door open after a shower helped a bit with humidity, but only if I didn’t run the exhaust fan too long.
4. Tried putting a bowl of water near the radiators - honestly, didn’t do much, but every bit helps.

The HRV is great for air quality, but yeah, it’s not a miracle worker for dryness. I’m still fiddling every year to find the right balance. Have you ever tried those whole-house humidifiers that hook up to your furnace? I’ve been debating if it’s worth the hassle or just another thing to maintain...

- Looked into those furnace humidifiers a while back - seems like mixed reviews.
- Heard they can help, but you’re right, more maintenance (and if they leak, hello window condensation).
- Ever notice if your windows fog up more when you run the smaller humidifiers? Sometimes dry air points to leaky seals or older glass, too. Wonder if that’s part of the battle in these older homes...

Yeah, I definitely see more condensation on my old double-hungs when I crank up the portable humidifier in winter. Tried a furnace-mounted humidifier a few years back - honestly, it kept the air less dry but also made the drafty window problem way worse. Ended up patching some seals and swapping out a couple panes. In my experience, if your house isn’t sealed up tight, adding humidity just highlights every weak spot. Maintenance is a pain too... filters, cleaning mineral buildup, that sort of thing. Not sure it’s worth it unless you’ve already dealt with the window and insulation issues.

I’ve been running into the same thing this winter - got a little ultrasonic humidifier for the bedroom, and suddenly every morning there’s moisture on the inside of the window glass. I never realized how much those old wood frames leak until now. It’s a weird tradeoff: better humidity for my skin and sinuses, but now I’m wiping down sills and worrying about mold.

Patch jobs helped a bit, but I’m starting to see why people say to tackle insulation and window upgrades before investing in humidifiers. The maintenance isn’t terrible yet, but I can see it getting annoying with more rooms or a bigger unit - filters, white dust everywhere, etc.

I do think a bit of extra humidity makes the house feel warmer, though. Maybe it’s psychological, but it helps with static and dry hands. Still, if you’ve got older windows like mine, it’s kind of a catch-22... fix the drafts first or risk water damage later. Not sure there’s a perfect answer, but I’m learning as I go.

Man, I’m right there with you.

“It’s a weird tradeoff: better humidity for my skin and sinuses, but now I’m wiping down sills and worrying about mold.”

That humidity battle is real - especially with older windows. You’re not alone juggling towels and plastic kits. Have you tried cracking a window just a hair when the humidifier’s running? Sometimes it helps balance things, though it feels counterintuitive in winter. I see folks get frustrated because even with all the DIY tricks, those single panes just aren’t built for today’s indoor moisture levels. Out of curiosity, how old are your windows? Sometimes even small upgrades like new weatherstripping can make a difference, but yeah, full replacements aren’t exactly cheap.

Yeah, single-pane windows and humidity just don’t mix well. I’ve done the towel-under-the-sill routine more winters than I care to admit. Cracking a window helps a bit, but then the furnace kicks on more and the bills creep up. I swapped out old weatherstripping last year - cheap fix, but honestly, it only made a small dent. Until I can justify shelling out for new windows, it’s just managing the symptoms. It’s wild how much moisture we pump into houses now compared to when these places were built.

I get what you’re saying about weatherstripping not doing much, but I actually had a different experience. Maybe it’s the kind of windows or just the way my house sits, but after I swapped out all the old, crumbly stuff and added those plastic shrink kits, the drafts and condensation dropped way more than I expected. Still not perfect - like you said, single-pane is just a losing battle - but it bought me a couple years before shelling out for double-pane. Sometimes I wonder if part of it is just how much we cook and shower now compared to back in the day…
