Excellent OEM Replacement
Excellent OEM replacement. Why shell out a few hundred bucks to an HVAC company?! They're super easy to test and replace and I always keep a spare on hand.

Check everything twice.
I'm impressed. At first I thought it was defective but after rechecked with a different meter, I found my meter was off. It works as promised and after a month still working well. The problem was with a second start capacitor. Always recheck your work.

Easy A/C repair
So far so good. Easy to install. A/C company said $580.00 to replace the one in my A/C that was supposed to be bad and needed to be replaced. I looked on You tub and saw that it was a 20 min job max. I searched the part and found the one I needed on Amazon for about $45.00. Replaced it and A/C works fine now. Saved about $500.00 on this DYI install. Such a rip off by the A/C company. Pj

Not used but have on hand just in case mine fails on day
Looks like good quality anyway. Have not used but ready to replace the OE cap on my Lennox if it fries. Watch a quality YT Video-'The DIY HVAC Guy' is a good channel-on how to install it and how to use a multimeter that measures capacitance in farads and maybe a cap discharge pen too. Cheap insurance compared to what a HVAC company will charge you for this simple but VERY expensive job. At least don't let them sell you an entire new system instead of this relatively cheap part.

Learn to do this yourself and save tons of money
This is a perfect fit for my outdoor condensing unit. The hvac company we had come out was charging us $600+ to swap out one that was getting close to its recommended usage (outside its normal operating range). Instead of paying that crazy amount, I got this and within 10 minutes, I swapped it out myself. Problem solved for pennies compared to what they were quoting. Got another for our other unit in case that one needs it in the near future as well. Do yourself a favor and learn how to change these up yourself and treat yourself to a nice dinner after because, you'll still be saving money even factoring in your pat on the back reward.
