Have you noticed any water stains or soft spots around the baseboards or under windows? That’s usually a giveaway something’s off behind the scenes.
That’s solid advice—those soft spots can be sneaky. I’d add, even if you don’t see obvious staining, run your hand along the wall near the floor and feel for any coolness or dampness. Sometimes leaks are hidden inside the wall cavity and don’t show up right away. Have you checked around any radiators or heating pipes, especially if your living room’s so much warmer than the bedroom? In older homes, I’ve seen tiny pinhole leaks in heating lines cause weird humidity spikes in just one room...
Funny you mention pinhole leaks—I once spent weeks chasing a mystery damp spot in a client’s den, only to find a hairline crack in a radiator elbow. You’re right, those tiny leaks can throw off the whole room’s climate. Don’t get discouraged if you don’t spot anything obvious at first... sometimes it takes a bit of detective work.
Had a similar headache last winter—kept fiddling with the thermostat, but the living room was roasting while the back bedroom felt like a walk-in freezer. Turned out, the culprit was a tiny leak in one of the old copper pipes behind the wall. I’d never have guessed it’d mess with the heat balance that much, but patching it up made a world of difference. Sometimes it’s the smallest things that throw everything off... and it’s not always obvious where to look first.

That’s so true. I’ve seen uneven heating pop up for all sorts of reasons, but leaks behind the walls are sneaky. I usually start with the basics—check all the vents and radiators for blockages or closed dampers, and make sure nothing’s blocking airflow (like furniture or thick curtains). After that, I’ll run my hand along the exposed pipes to feel for cold spots, which can hint at leaks or air pockets.
One thing I always worry about is insulation. Sometimes the problem isn’t even in the pipes—it’s just a drafty window or a gap in the wall letting all the heat out. Did you notice any cold air coming in around windows or outlets in that back bedroom? I’ve been burned before by assuming it was a heating issue when it was actually lousy insulation doing most of the damage.
Curious if you had to cut into the wall to find that leak, or did you spot it another way? Always makes me nervous poking around in old walls, especially with copper pipes.

That’s exactly where I started too, but I still get paranoid about what’s hiding in the walls. I’m honestly not comfortable cutting into anything unless I’m 100% sure. Sometimes it feels safer to just call a pro, especially with old copper pipes—one wrong move and you’ve got a bigger mess. Insulation’s a huge deal though, like you said. Drafts sneak in everywhere... even those little gaps around outlets can make a difference.
