AC Season is coming up. Keep extras!
I keep about a half dozen of these capacitors around for when summer is coming. Usually I only need one or maybe two per season for my own AC but I've saved lots of neighbors headaches and got them running quickly. They’re inexpensive, reliable, and exactly the kind of part that can save you from paying a steep service fee for something that takes only a few minutes to swap. The build feels solid and they work well for small fan motors and AC units. It’s still important to be careful and know your limits when working around electrical components, but having a spare on the shelf can make a hot day a lot less stressful. AC Repairman typically take 4-6 hours to show up and charges $120 to switch out this part in 10 minutes.

My AC works again!
My outside fan stopped turning, exhibiting the normal symptoms of a failed capacitor. I was able to "push start" the fan by manually turning the blade. This $10 part and 10 minute installation saved me a lot of money over a service call to my business!

Great alternative
HVAC friend recommended to replace what I currently had in my Trane XB unit. My god the company wanted for this part not the install. $200. Thanks AZ saved me a bunch of money.

Fixed the furnace overnight
I discovered on Sunday morning that my furnace blower wasn't working. A quick test with a meter showe a possible bad capacitor. It was going to be cold enough for frost so I tried finding a capacitor locally on a Sunday and nobody had it. Since I work during most supply house's hours I would have trouble getting one quickly. Amazon to the rescue with 4-8 am next day delivery. The furnace was running by 6:45 AM Monday. 4 stars becaus the tolerance is higher than factory part so I will still have to get a proper spec and keep this as a spare. Can't complain for $12.

Great replacement for our 20+ year old furnace, so far
This is working great in our old furnace. It was a inch or so taller but everything else was the same. So it fit into the original bracket without any modifications or adjustments. The old one crapped out all of the sudden. For $7 each I ordered 2 so that I have a backup and because I have 2 furnaces (one upstairs and one downstairs) that are the same model. So far so good and will update my review if needed. Make sure to discharge the old one before you go accidentally touching it and shock yourself trying to take it off!

When you need a capacitor for an AC motor, nothing else will do!
Great fit, wired up easy.

Fixed our HVAC blower motor!
Outside AC unit is running, but nothing's getting cool - yikes! Crawled up in the attic (wow it's warm up there!) and discovered the "computer" is trying to run the blower motor, but it isn't going in spite of getting the correct voltage. I took a chance that the motor capacitor might be bad and ordered this. Thank you Amazon for super fast delivery - our house is cool again!

The perfect replacement for my AC units fan. Dropped in, and my old girl came back to life. The HVAC store wanted $100 for it, but thanks to this seller, I was able to have my ac unit fixed for a fraction of the cost.

Work great, it slightly small in diameter then the original, l had to add a small piece of rubber for it to be tight in the holder. But other then that it's great. We will see how long it last.
