Hvac run caps


Over the last several summers in Oklahoma, the number of bad split and regular run capacitors I encounter has become insane. I would easily say it encompasses 60-70% of my no cooling calls.
10 yrs ago I didn't even own a tester. Now it's nearly all I do. Even the older, better manufactured ones. Does anyone know the cause of this?

Hvac run caps


I wouldn't count it out, but it's always been extremely hot here. I guess what I'm wanting to hear is a stretch really. Not knowing much about the way electricity is manufactured I kind of assumed it had something to do with spikes in the stein waves causing them to swell and burst. Like I said earlier, it even happens to caps that have been running summer after summer for decades. I'm at a loss here, just want to put my finger on it. Thank you for the reply, I was starting to think I posted a dumb question lol

Makes me better appreciate a 3 phase. So I'm guessing a man can't find a more durable brand of dual rated caps, right? It's just a circumstantial thing?
