I have known there was a thing called a "compressor hard start kit" for years. I had never seen one and did not know exactly what they did. But in fear of losing my condensing units compressor in the hot, hot Texas summer, I decided to try one out. So I ordered this CSR U2. I came in a couple days, and I immediately set out to install it. The instructions were good enough for me to get it installed by my self. It looks to be a large capacitor and some type of switch or something. I did not need to cut any wires as all the wires came with 1/4 inch female spade connectors. They just slide onto the existing capacitor, etc. To be honest, I was not sure I had it installed correctly until I turned the power back on and tried it. You would not believe the difference it made. Now the compressor sounds completely normal when starting. My air conditioner lasted through the rest of the summer and I have forgotten about needing to replace my system. I have run it this spring on a couple hot days and it is still working fine.
I would highly recommend this product. And if you are handy at all, you can likely install it your self. I have no doubt it saved my compressor from premature failure. I'm keeping this hard start kit, and it is going on my next A/C condensing unit.
So there you have it. If you found my review useful, please let me know.
Hopefully I never need to buy another one of these, but if I do, I'd do this again.
Installation: schematically and hooking up the wiring was a piece of cake....the hardest part was mounting the capacitor. The mounting area had several slits, and holes...but finding a pair that matched size wise, and allowed for a proper mounting position that would be safe and secure was a real pain. So I ended up cutting (2) inch long X 1/8th inch wide slits wide enough apart to accommodate the capacitor size, and allow me to use a "worm drive" hose clamp... allowing it to wrap around the cap, and facilitate tightening to secure it to the mounting plate. I first wrapped the capacitor with Silicone Self Fusing Tape, to insulate and cushion it from the metal clamp. I mounted perfectly!
Results: Wow, could actually hear the difference with the start-up....AND...the shut-off of the compressor. Which tells me that those cycles are not exposing the compressor starting coils to long and labored transitions....and a bonus is that it actually uses less electricity in the long run. I highly recommend this product and modification. Well worth the modest cost and hassle in mounting it.
- extend compressor motor life by reducing inflow current and heat
- reduce voltage variation at startup in your house
- potentially start a hard to start compressor if it's just slightly off nominal... this is my case... my compressor wouldn't start, got one of these, put it on, started right up... total time expended about 15 minutes
it's important to note that this is actually a smart preventative thing, not a hail mary to keep your compressor running ... I took a shot and got lucky so maybe I replace my compressor next year instead of this year....
if you are gonna get one, get it now...
for sceptics, this capacitor design is frequently used in modern premium compressor designs so it's a fully endorsed design and you can install it with confidence
