It’s wild how many people don’t even realize their vents are under furniture until you point it out. I was helping a buddy move his entertainment center last month and we found a vent that looked like it hadn’t seen daylight in years. No wonder his living room felt like a sauna and the back bedroom was freezing. I get wanting to make a room look nice, but if you’re blocking half your airflow, you’re just asking for trouble. And yeah, those “super” filters are only as good as how often you swap them. I’d rather remember to change a cheap one than forget about an expensive one.

You nailed it—blocked vents are a sneaky culprit. Ever check if your returns are clear too? Sometimes folks forget about those, and it throws the whole system off. And yeah, those “super” filters... I’ve seen more than a few systems choke because someone forgot to swap them out. Even the best filter’s useless if it’s caked in dust.
Blocked vents are classic, but I’ve seen folks overlook the returns way too often. You’re right—if those are clogged or even just dusty, the whole airflow balance goes sideways. I’d add: check for furniture or curtains blocking anything, too. Had a tenant once who stacked boxes in front of a return and wondered why the AC was struggling. It’s usually a combo of little things, not just one big issue. You’re on the right track—keep poking around, you’ll get it sorted.
Funny you mention the returns—people always forget about those. But I’m curious, has anyone tried using those vent deflectors or magnetic covers to redirect airflow? I’ve read mixed things about them. Wondering if they actually help or just mess with efficiency.
I've seen folks use those vent deflectors, especially in older homes where airflow's never quite balanced. They can help a bit, but if you block too many vents or use magnetic covers on supply vents, you might end up stressing the system. Ever checked if your returns are actually clear and unobstructed? Sometimes furniture or dust buildup does more harm than a vent cover ever could.
