Easy to install instead of paying OOP to a professional
Fits perfectly with my Rheem AC units. Replacing the old one was just as easy as cutting off the breaker, pulling the disconnect, taking the electrical panel off and swapping the wires. It works exactly as expected and doesn't make a sound. Solid build and reliable performance for my AC motor so far. Great value for anyone needing a replacement or upgrade capacitor.

Excellent
This worked great. It was smaller then one I had before but same uf.

Fantastic direct fit Capacitor for Rheem Classic, quick shipping, quality product
My Rheem AC unit stopped blowing cold air, and then I noticed the fan was not starting up. I immediately suspected the capacitor because I live in Palm Springs and it's triple digits most of the year lol I have never worked on an AC unit before but before owning my own home my landlord had a similar problem and she paid $2,000 for same day HVAC service and the technician literally just did a look over and change the capacitor and charged like $200 for a capacitor. This was a direct fit, shipping was so fast. I'm definitely going to order another one to have just in case I need to replace it in the future. My capacitor was so bulged out it had obviously been struggling for a while. I highly recommend this item and this seller

Helped correct outside unit problem quickly and easily
This fixed a problem with the outside unit not running when the rest of the air conditioning system was trying to cool the house. Verified power was getting to the unit and the relay was working, but neither the fan nor the compressor started. The old unit also had oil leaking from it, which suggested it may be the problem. Replacing the capacitor fixed the problem. Next day delivery helped to get the AC repaired quickly in the summer heat. This unit was slightly smaller diameter than the one it replaced, but a little tape around the perimeter helped to snug it in the mounting bracket. Be careful. Turning off the AC does not cut power to the outside unit and it runs on 220VAC. To minimize the chance of electrocution while working on the outside unit, the breaker for the outside unit must be turned-off or the power cut-off at the outside junction box. The old capacitor might hold a residual charge as well. If you are not sure what you are doing, find someone that is.

Saved me over $100 in service fees! Definitely worth checking the capacitor
My HVAC suddenly stopped working. The fan wouldnโt turn on, and the AC wasnโt blowing cold air. I called an HVAC service, and they said theyโd have to come check the unit, with a $95 dispatch fee plus additional charges for parts and labor. Before scheduling, I checked YouTube for possible fixes and found several videos recommending to check the capacitor. Sure enough, that was the issue! I ordered a BOJACK 45+5uF 45/5MFD ยฑ6% 370V CBB65 Dual Run Circular Start Capacitor from Amazon for under $20, replaced it myself, and the AC started working like new again. It is easy to install and took only less than 15 minutes. Iโm really glad I tried this first and it saved me over $100 in service fees! Definitely worth checking the capacitor if your HVAC suddenly stops blowing cold air.

Came burning hot in mail but works just fine.
The product was sitting in my mailbox in 100-degree weather for so long that it was so hot that I worried it had been damaged by the heat. I checked using a multimeter, and one of the leads showed no resistance, so I thought the capacity was damaged by the heat. Nonetheless, the AC fans and compressors came back to life after I replaced the damaged one. Therefore, I believe that my method of testing a capacitor, which is a popular and simple approach, may not be entirely reliable. This is a good capacitor; go ahead and buy it.

Failed in less than 3 years.
Last less than 3 years. Ordered a different brand part this last time with a 5 year warranty.

Fixed my A/C issue fast
Easy to install and worked perfectly to get my air conditioning running again. Great value and arrived quickly. Lifesaver during the heat wave.

My AC is working again
Worked flawlessly for me. My AC compressor fan stopped working. ChatGPT recommended new capacitor. I found this one. It is the same diameter as my old one and one inch shorter, which made a replacement super easy. It's been working for a week now.

DIY HVAC repair, worked!
Did a quick youtube search following g my blower fan malfunction. Looked like the capacitor was swollen, made an educated guess that it was due to a bad capacitor... bought this, and it's been running great since. It's been 5 months, no issues. If they keep their prices fair, I'll be coming back whenever it goes bad again.

Price is as good as you will find.
Works perfectly - great price - perfect. Product has been working great now for 2 years.

Works
So far working great. Only been 3 weeks. OEM lasted 16 years. If this lasts half as long it should get me to AC replacement time.

Great replacement for 27L880 capacitor
Bought this capacitor to replace a GE 27L880 capacitor in a central a/c unit and it was perfect. Ordered in the evening and I got the part at 9 am next day. Wow.
