Had a property a few years back with the same issue—owners were convinced adding two solar attic fans would solve their summer heat problems. They spent a good chunk installing them, but the place was still roasting up top. When I crawled up there, half the soffit vents were painted shut and the rest were packed with old insulation and dust. No real airflow coming in, so the fans just spun their wheels (literally) for nothing.
Honestly, I get why people want a quick fix. But if you don’t have clear intake at the soffits and decent exhaust up high, you’re just moving hot air around or, worse, pulling conditioned air out of the house itself. I’ve seen folks pay for all kinds of gadgets when all they really needed was to clear out those soffits and maybe add a ridge vent.
It’s not glamorous work, but balancing intake and exhaust has always made the biggest difference in my experience. Fans are fine as a supplement, but they won’t cover up poor basics. Sometimes it’s just about getting up there with a flashlight and seeing where things are actually blocked.
That’s spot on about the basics making the biggest difference. I went down the same rabbit hole a few years back, thinking powered fans would be a game changer. All it did was make the attic sound like a small airport, but temps barely budged until I cleared out the soffits and added a ridge vent. Sometimes it’s just about getting dirty and doing the unglamorous stuff first. It’s not flashy, but man, it works.
Funny, I used to think those powered attic fans were the magic fix too—until I realized all they really did was suck conditioned air from the house, especially if the soffits weren’t clear. It’s wild how much difference just unblocking vents and putting in a ridge vent can make. Not glamorous, but it’s way more effective (and quieter). For me, the hardest part was just crawling around in that old insulation clearing everything out... but totally worth it. Sometimes “boring” wins.
I had a similar experience with those attic fans—seemed like a great idea at first, but after a couple summers, I realized my upstairs was actually getting hotter. Turns out, the fan was just pulling cool air from the house right up into the attic and out the roof. Not ideal when you’re running AC. Once I figured out my soffit vents were mostly blocked with old insulation and dust, I spent an entire weekend up there (itchy as heck) clearing them out and putting in baffles. Added a ridge vent while I was at it.
I’ll admit I was skeptical about how much difference it would make, but it’s been way more comfortable since then. And yeah, not as flashy as some high-tech solution, but quieter and honestly less to break down the road. Only thing I’d do differently is wear a better mask next time… that old insulation is no joke. Sometimes the simple fixes are the best ones, even if they don’t seem exciting at first.
- Not sure I’d call attic fans a total bust. In bigger multi-unit buildings, I’ve seen powered fans help a lot—especially when the insulation’s up to code and the soffits are clear.

“the fan was just pulling cool air from the house right up into the attic and out the roof”
That usually means air sealing between attic and living space wasn’t tight enough. If you can stop that leakage, fans can actually keep temps down without sucking out your AC.
- Ridge vents + baffles are great, but sometimes in older buildings with weird rooflines, passive venting just doesn’t cut it during heat waves.
- Personally, I’d say it’s case by case—sometimes simple works, sometimes you need a little more tech.
- Agree 100% on the mask though... fiberglass is brutal.
