Review: Working AC Huzzah! - This thing saved my ac fan motor, and instantly brought the temperature back down to livable. It showed up quickly, installed smoothly, even though it was smaller than the previous capacitor it replaced with the same number range. No problem a little weather stripping and a bigger mounting washer couldn't fix. All of the wires clipped into place as they should, and I was pleasantly surprised at how clearly labeled each terminal was. Better than the OEM.
Review: 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.

### ⭐⭐⭐⭐⭐ Fixed my A/C.
*by J***R on April 8, 2025*

Perfect fit and specifications for my 4 ton Ruud Unit. Still working perfectly. Update 8/10/2025. I purchased the first one in June of 2023, still working fine. I purchased a spare a few days ago because of a brutal heatwave that forces my A/C to run almost non-stop and the frequent brownouts, all capacitor destroyers. As noted already its a quick easy fix if your compressor or your fan motor won't start. It is preferable to have a meter to confirm the cap is bad but even if you don't, having a spare one on hand in a pinch is worth the $20 even if it turns out that is not the problem. That's it, may your A/C always run cold.
