Review: This product saved me $1200 - First the background information: I couldn't get my 13.5 btu AC unit on my 5th wheel trailer to start/run while using my brand new 3300 watt generator. Within 1-5 seconds of starting the AC unit, the generator's overload would trip and shut down the AC unit, or the AC circuit breaker would trip. Either way I couldn't run my AC while using generator power. I even tried other people's generators (of greater power) to no avail. The RV service center said I needed a new AC unit to the tune of $1200, plus installation. Others tried to sell me bigger and more expensive generators. I ordered this hard start capacitor from desertcart for around $12. It took less than 2 minutes to install. It actually took longer for me to climb up on the roof of my 5th wheel and take off the AC cover than it took to install the hard start capacitor. I started my generator and turned on the AC unit. The AC immediately started and continued to run for about a half hour before I manually turned it off. By the way, the outside temperature was around 95 degrees F at the time of this test and the inside temp was well over 100 degrees F. Two weeks later we took the 5th wheel on a week long camping trip. The day time temps ranged from upper 80's to the low 90's. I ran the AC unit using generator power for several hours a day over the course of several days. The AC would cool down the inside of the 5th wheel and the cycle on and off as necessary without problem. I have since used the AC on generator power a couple more times during temperatures rang from upper 90's to 100 degrees F. Needless to say, I'm more than completely satisfied with his product. Simple and fast installation. Works exactly as advertised. I have already recommended this product to many people.
Review: Works great but not much in the way of instructions - This hard start capacitor works great and was pretty easy to install my self. There was not much in the way of instructions but there are lots of instruction videos to be found online that helped.

### ⭐⭐⭐⭐⭐ Saved the life of an otherwise "dead" central AC system/compressor.
*by T***E on July 26, 2014*

This literally saved the life of a central AC system (3 Ton 220V). Two contractors before me came to look at it, and gave the same diagnosis (bad compressor, entire system needs to be replaced $6000). I looked at this system as a favor to the homeowner, since someone else was messing with it, the first thing I did was recover the refrigerent, evacuate, and recharge to factory spec, then I saw The problem was the compressor would not start, every time the system called for cooling, it would hum for 2seconds and kick off on thermal overload protector. I installed this about 3 months ago, and the compressor started right up, and unit began cooling immediately. Unit has been running all season every day with no issues since installation. If you have a compressor that is not starting (thermal overload shutdown), its definitely worth a $20 gamble to try one of these. If you have a system that is simply "not getting cold", you need to do a little more troubleshooting before messing with one of these. Update 6-14-2015 - unit is still running good as new a year later! If you have a compressor that is not starting because it is cutting out on thermal overload (5 second hum then click), this is worth the gamble to try and save it.
