When your living room is a sauna but your bedroom's an igloo

Had a similar thing happen, but with a return that was just painted shut. Didn’t even realize it until I started wondering why the AC was running nonstop and the bedroom felt like a fridge. Took a utility knife to the edges and suddenly, airflow everywhere. It’s wild how something small can throw off the whole system. I’m still not convinced those little filters behind the returns do much, but I guess every bit helps...

Funny, I used to think the same thing about those filters. I swapped mine out for a better grade and actually noticed less dust around the vents, but I’m not sure it made a huge difference for airflow. Ever try running without them for a bit? I always wonder if it’s worth the hassle or just another thing to remember.

I’ve had a similar experience—switched to higher MERV filters and the dust definitely decreased, but airflow felt about the same. I do think they help keep the system cleaner long-term. Skipping them entirely made my ducts way messier and probably less efficient over time. It’s a bit of a tradeoff, but I’d rather deal with swapping filters than cleaning out ductwork.

I get what you’re saying about the tradeoff. I’ve tried skipping the filters before, thinking I’d save a few bucks, but honestly, it just wasn’t worth it. The amount of dust that built up in the ducts was ridiculous, and cleaning that out cost way more than a year’s worth of decent filters.

Couldn’t agree more there. I will say though, those high-MERV filters can get pricey, and sometimes I wonder if the extra cost is justified for regular homes. I stick with mid-range ones now—seems like a good balance between airflow and keeping the dust down. Plus, swapping them out every couple months is way less hassle than dealing with uneven temps between rooms or paying for duct cleaning.

Honestly, if your living room’s roasting and your bedroom’s freezing, it might be more about airflow balancing than just the filter grade. But yeah, clean filters definitely help keep things running smoother overall.

Yeah, I’ve wondered about those high-MERV filters too. I mean, unless you’ve got allergies or pets everywhere, mid-range seems fine.
