Product review (5 stars): No Brainer
The most arduous part of the process to install this product was trying to make sure that it was compatible with our air conditioner. The instructions on the packaging and the response from the seller we're not very helpful at all. Single phase air conditioner? What is that? Operating volts? We didn't know that there were different kind of volts?

However we called Supco and spoke to their technical support and were finally able to determine that this was quite likely compatible with our air conditioner.

The technical specification label on our AC was very cryptic, to the unitiated, us, however the information is apparently there, as you can see in the picture we uploaded. The number 1 in a square box with the letters PH next to the number 1 apparently mean "single phase" and apparently "volts 208/230" refer to operating volts. Now we are not saying this is 100% correct as we could possibly have been misinformed.

However these are conclusions we arrived at when speaking with the Supco technical support department.

In addition we were told by Supco technical support that this item is their #1 selling item/hard start kit and is compatible with most residential air conditioners.

In addition, it's super easy to install, is an extremely inexpensive component and can according to some HVAC pofessionals/experts be the difference between an early demise of one's air conditioner and a long long long healthy life, makes getting this to seem like a no-brainer. But time will tell.
