Realized I was using the wrong capacitor size for years

I was swapping out run capacitors on condensers for like 5 years just matching the MFD from the old part. Then a guy from Carrier told me to check the actual specs on the unit label instead. Turned out I was under-specing some of them by 5-10 MFD. Anyone else make this dumb mistake or am I the only one?

Wait, you just match the MFD from the old one? I always thought that was the way to go too, kinda figured if it ran it was fine. But hearing that you were under-specing them makes me think I should start checking the labels on units myself, been doing the same thing for years without question.

Take a closer look at those labels, half the time the numbers are worn off anyway so matching by feel is the real trick.
