Review: Easy to Install AC Capacitor - Good start/run capacitor. It meets the listed specifications and is easy to install. Works very well in air conditioning systems and provides a reliable start. Good quality and great value for the price.
Review: It Works! Way Cool! - The AC only chooses to stop when it's really hot out. Edsel Murphy reminds us that such failure times will happen late on a Friday afternoon, and after the local supply places and HVAC contractors toggle to "exorbitant prices for a service call three weeks from now" mode. As soon as I found the problem on Friday evening, the part was on order here, with a promised Monday delivery. The delivery Gods were hard at work over the weekend apparently, because the part was in my hand in time to get it installed well before lunchtime. Thanks desertcart, the folks in the warehouse and shipping, and those aforementioned delivery Gods in a dilapidated Post Office buggy. --- The capacitor works perfectly and the system has been hard at work since last Monday. This cap is slightly smaller in diameter than the original in our Carrier AC unit, solved with a little creative work on their bracket. Else it was a plug-and-cool effort. Daily mean air temps here have been running at least 10ºF above 'average'. July was all over 90º daytime highs, many 100's, new records set. At 4000' altitude in what's normally a low- to mid-80's resort area on the eastern slopes of the Cascades. Hot. How spoiled we are to have air conditioning. About a third of our neighbors don't. Bottom line -- Good working product, perfect for our particular application, all but self-installing, and at a great price compared with the local purchase options I explored. One of those was a company that explained that these are too dangerous for an amateur to even think of servicing themselves. Over $600 to come install one for me. Um, no thanks, I've got this covered... I'll probably get another one as a spare, and leave it stored in the unit. That should put the fear in the one I just installed, maybe enough to last at least the ten years plus two months that the original one was in service. On our ten year factory warranty... Stay Cool!
