Found a stat about capacitor failure rates that really got me thinking

I was looking up some repair logs from a job I did last week on an old stereo receiver and stumbled onto a study from 2019 that said roughly 40 percent of electrolytic capacitor failures are caused by heat damage, not age. I always figured they just wore out over time, but it turns out poor ventilation in tight cases is a bigger killer. I run a small plumbing crew and we deal with similar issues in pumps, so it made sense when I thought about it. Has anyone else found numbers like that that changed how you approach a repair?

I heard a similar stat from a buddy who works on HVAC units, he said over 50% of failed start capacitors trace back to heat buildup from dust or bad airflow. That changed how I look at keeping electronics clean, not just swapping parts. Do you think most people miss simple stuff like vent cleaning?

Dust killing electronics that fast? That's wild, never figured grime could take out capacitors like that.
