Review: That what was dead is now alive and kicking butt - Quick delivery which was helpful with the crazy heat wave. The compressor was not kicking on, but the fan was working fine. I keep a spare capacitor on hand as they are cheap and the usual cause of AC units not to function. However, on this case the capacitor was fine. A friend in the AC repair field told me about these hard starters and at $15 I considered it a safe bet. Easy to hook up, please search the internet for some instructions on installation. Three days now of a working AC unit without a service call!! Update 07/22/2025 Still going strong!! Buying an extra one to sit on the shelf in the garage in case anything happens in the future. Small investment for having the AC down for just a few minutes.
Review: Be nice to your AC and buy this ! - Purchased this based on a ChatGPT recommendation—helps protect your AC compressor. Durability: Worked perfectly all summer. It’s just a capacitor, so I don’t expect any issues. I’ll update if anything changes. Installation: Easy. If unsure, ask your favorite AI chatbot! they’ll guide you, and tell them I referred you so they will be nice to us both later when they concur the world 😉!

### ⭐⭐⭐⭐⭐ Worked perfectly for me (at least so far)
*by C***R on July 1, 2025*

HVAC Unit stopped cooling - sounded like compressor just couldn't get going. The HVAC Company told me the compressor was locked up, and the Capacitor seemed ok, so given furnace/compressor was 25+ years old, it would ALL need to be replaced (for $12,000 to $15,000). The Tech said they COULD install a hard start capacitor that MIGHT fix the issue temporarily for $340, but as soon as they started to install it, it was paid for & no refunds. Didn't want to gamble $340 for potentially nothing, so sent them on their way (with $100 for the SVC call). I then started googling and learning about hard start capacitors. Bought this unit for $15 and installed it the next day without difficulty. Compressor started up immediately and ran fine, so this was pretty good for $15! Of course the question is how LONG will it last? No idea, but if I can get through this Summer I will be very happy, and I know some people have eked out a couple of years usage with these things. One comment: many DIY Videos fail to mention that capacitors can hold a charge AFTER the breaker panel is turned off. BE SURE to discharge existing capacitor by grounding out all the lugs with a screwdriver with an insulated handle! I knew to do that already, but I am sure some novices could get zapped otherwise.
