25 µF Capacitor
I installed this capacitor while repairing my RV rooftop AC, and it matched the specifications of the original component. The terminals were properly aligned, installation was straightforward, and the overall construction feels solid. Once installed, everything operated normally. It's nice having a UL-certified replacement available. Good replacement capacitor for repairing compatible equipment. Installed and tested to evaluate fitment, build quality, and performance.

I would buy it again!
So our air conditioner stopped blowing cool air and before we paid an HVAC company a few hundred dollars to diagnose and fix our much older unit, we decided to try to fix it ourselves. We notice the can in the unit was mis-shaped so we hoped that if we replaced it, that would fix our problem. This can arrived quickly and was packaged very well. The replacement can fit perfectly. It was the exact same size so my dad was able to swap out the cans very easily. It was a great value for the money as it fixed our issues and saved us hundreds of dollars being able to do the replacement ourselves. After changing out the capacitor, the units cooling performance increased in the home. I would definitely recommend this product to everyone and I would definitely purchase again if needed in the future. Please make sure that if you decide to replace the capacitor on your unit that you remember to disconnect all power to the unit before removing the old one or putting in the new one.

A well-made lifesaver!
I bought this last summer just to throw in the garage as a 'just in case' and I'm sure glad I did. I came home from lunch to a house that was over 80 degrees. Some quick diagnostics with a multimeter later, I had this unit installed and my system was running beautifully and cooling yet again! The only hiccup is this is skinnier but longer than the old one. My system lets the capacitor 'hang' by it's top rim through a round hole in the bottom of the panel. I made a ring out of a few zip-ties and put them around the top of it and it slipped into place just fine. Overall a great value when you compare it to the 'name brand' capacitors. Even if it doesn't last as long as a Titan or whatever, you can buy two of these for the price of one of those and keeping one in the garage makes for a quick, easy swap.

Best Replacement
My house is almost 20 yrs old and I have not changed anything on my Lennox A/C unit until now. The capacitor went out. When I changed my old capacitor, it was rusted and couldn't see any writings on the top to connect the correct wires. I was able to clean it up enough to see the "C", "Fan", and "Herm" writing on top. Anyways, this capacitor work excellent. It fits my old one exactly, and it was not expensive at all. If my second A/C condensor goes out, I will buy this item again. No question. Thank you for this product.

Perfect replacement capacitor for our heat pump. Very cost effective to replace this part rather than having a contractor do it a few hundred $,
