Makes me wonder how many folks are fighting their HVAC when it’s really just a leaky spot somewhere...
Yeah, leaks and insulation are big, but I’ve seen plenty of cases where people ignore the vents and registers too. Sometimes they’re blocked by furniture or clogged with dust—doesn’t matter how good your insulation is if the air can’t move. I’d say check both before spending money on gadgets or upgrades.
Honestly, I’m with you on the vents and registers—people overlook them all the time. But here’s another thing: check your doors and windows for drafts. I once spent a weekend sealing up gaps with weatherstripping and it made a bigger difference than fiddling with the thermostat ever did. If you want to get really detailed, grab an incense stick and walk around—watch where the smoke drifts. Cheap, easy, and way more effective than buying another “smart” gadget that promises to fix everything.
I get what you’re saying about the drafts—weatherstripping made a huge difference in my place too. But I’m still convinced airflow is the main culprit for weird temperature swings. I spent way too long adjusting vent dampers and still had hot and cold spots until I realized my return vent was basically blocked by a bookshelf. After moving it, the temps evened out a ton. Has anyone tried balancing their system with those little airflow meters? Wondering if it’s worth the hassle or just overkill for a regular house...

Man, it's wild how something as simple as a bookshelf can throw your whole system off. I've seen people chase their tails over drafts and insulation, when really it's just the air not getting where it needs to go. I get what you mean about those airflow meters—I've played around with one from work just for kicks. They're cool if you're into numbers, but honestly, for most houses, it's probably more info than you need. Unless you love tinkering or your place is a maze of weird add-ons, just making sure nothing's blocking returns and supply vents usually does the trick.
That said, I did run into a place once where no matter what we did, the back bedroom was freezing. Turned out there was a bird’s nest in the duct. No fancy meter would've found that... Sometimes it’s just good old-fashioned detective work.

Funny how often it’s the obvious stuff, right? I had a tenant swear up and down their heat was broken, but turns out they’d stacked moving boxes in front of the only return in the apartment. Cleared that up and suddenly it was like a new place. Makes me wonder—has anyone ever dealt with those old houses where the returns are just tiny grates in the floor? I always question if they’re even doing anything or just collecting dust...
