It works, looks clean and is built strong. Back to clean AC in 10-15 minutes.

Arrived as advertised, install took 15 minutes with slight learning curve for this model heat pump and it fired right up as it did two days prior!Thank you for making a quality product and it hope the long term review will reflect a decent life span!We have many 'brownouts' and had another AC unit for out next door 36 hours prior to this one. Dirty grid power or regular outages of 5+ seconds are very hard on capacitors in air conditioners!I was curious so I looked into it and ~83% of all HVAC related service calls are capacitor related...I bought two for each unit so we have one sitting in the storage room to use as a quick fix next time one goes out.It is not about the quality of the capacitor as it is the amount of abuse the component takes.Signed of poor construction are barely starting the motor from day one to swelling of the can which indicates it was barely staying sealed when the insides want to blow up.The welds are great, can is clean, connectors are strong and sized properly.It provides the needed burst of energy to get the compressor running and I hope it continues for a long time to come.Best wishes and I hope this helps.

Fan is working again

I've noticed my AC condenser fan was not working. I learned online that there is a simple fix. I just needed to replace the old capacitor. This was a very simple fix. I first turned off the power to the AC, took photo of the wire connections. I installed the new capacitor and connected the wires just like it was connected in the photo. And now the fan is working. This whole process took less than 20 minutes.

Easy to change and works perfectly

I was in the middle of a Sunday night with no technicians available. I saw videos on YouTube about how to replace the condenser and how to identify the correct one. I ordered overnight, and it arrived at 5:30 am. Took me 20 minutes to replace it, and it's working perfectly. It was pretty easy to change. $400 less than any authorize AC company

Worth the money and easy install.

One day delivery and the heat is supposed to be 100 this week. Took about 10 minutes to replace and turn back on. Just make sure all power is off and out of capacitor before touching the old one. I took a pic so that I knew exactly where to put each wire. I highly recommend so far. No clue on how long they last yet. Happy customer here though.

Size Matters

The capacitor works well as soon as it was plugged-in. However, I was focusing on the capacity and the voltage rating, but didn’t know the capacitors come with different sizes for the same capacity and voltage rating. Make sure you pay attention to the diameter 2 inches vs. 2.25 inches so you get the desirable size because size does matter…

They said keep it short read the procedure on YouTube do it yourself..

Simple replacement for a homeowner with a little caution and paying attention to what you’re doing a seasonal check up person company told me I’d run between 200 and $300. I spent less than $15 .I am mechanically inclined, but it took about 17 minutes from beginning to end included, gathering up the proper odds and ends, needle nose, pliers socket set ,unscrew some parts, piece of cake.

So easy and inexpensive

Super easy, cost-effective way of getting your AC up and running again. The last time my capacitor went out, I was charged $350 to replace it. I later learned that capacitor replacement is one of the most common ways that companies rip you off. This time I spent $17 and it took me 15 minutes, start to finish, and I had never done it before. I watched a couple videos and that was it. Make sure you take a picture of your existing wiring setup before you pull the wires and just match it. I appreciate that I was able to order this part at noon and it was delivered around 4:30. Outstanding.

Easy DIY, Save Big $$$$$$$$$

After receiving a $750 quote for a capacitor replacement, we decided to go at DIY style.Honestly, electricity scares the bejesus out of me. Now you want me to discharge a A/C capacitor? I swear I watched many YT videos a gazillion times. We were ready.During the install we also super cleaned the drain pan, drain pipe, outlet, and outside coils.Matching up the capacitor with the old one is easy. Each connector is slightly different. 2 prong, 3 prong etc. Just switch over each connector one at a time.Oh the sweet, sweet sound of a working A/C !! After 10 minutes my wife the room vents. 81 degrees and dropping!We saved over $700. Literally amazing. Get a second capacitor too.
