Great value for a DIY central a/c repair
My central A/C unit suddenly stopped working during a heatwave, and I quickly came across this for a replacement after comparing symptoms to a faulty capacitor. The capacitor is sturdy and seemingly well built. Repairing my unit with this was very simple, and in less than 10 minutes, my A/C unit was working again. It has been holding strong for over a year now, and the value for this was huge. I saved so much money compared to calling in a technician for repairs. If my central a/c unit’s capacitor runs into any problems, I will have no problems coming back to this one.

House ac unit
Good replacement and is still working great and easy to install and saved me 400 dollars that the ac man would charge me to change it

Savior of my AC! BOJACK Dual Run Circular Start Capacitor Works Wonders!
I couldn't believe my luck when my air conditioner suddenly stopped blowing cold air during the hottest week of the year. Frustrated and desperate, I turned to online forums and stumbled upon a possible solution: a faulty capacitor. After some thorough research, I decided to give the BOJACK 45+5 uF Dual Run Circular Start Capacitor a shot – and boy, am I glad I did! Matching the specs with my old capacitor and cross-referencing with the product details, I hit the order button with a mix of anticipation and skepticism. But as soon as I installed the BOJACK capacitor and fired up the AC, I was met with a rush of cool air that instantly reassured me that I had made the right choice. The 45/5 MFD capacity was an exact match for my old capacitor, and the ±6% tolerance gave me the confidence that this was a quality replacement. The installation process was a breeze, even for someone like me who's not the most DIY-savvy. The clear labeling and instructions made the swap a straightforward task. Within moments, my air conditioner roared to life, and cold air started flowing through my home once again. It was like a breath of relief in the midst of a sweltering heatwave. The 370V/440VAC rating assured me that it could handle the demanding workload, and it did so with grace. The BOJACK capacitor truly saved the day – and my sanity – by bringing my AC back to life. This little powerhouse proved that sometimes, all it takes is a high-quality component to solve a big problem. If you find yourself in a similar situation, don't hesitate to give the BOJACK 45+5 uF Dual Run Circular Start Capacitor a shot. It's a game-changer that turned my frustrating AC ordeal into a success story. Kudos to BOJACK for a fantastic product! 🌬️❄️👏

Good DIY HVAC fix
Worked as expected on the outside AC unit. Easy to install and saved a lot compared to what the HVAC service company was going to charge.

Measure twice order once.
Like any of you who are reading the review, I have a similar story AC stopped working, hottest day of the year, partner decided to blame you, etc. So what do we do? We google what could be wrong, decide it's probably the capacitor, and go outside and check on the capacitor value. Perfect right? WRONG! You actually need to do 2 things not one (before you start though make sure you pull / turn off the fuse to the ac unit! This will keep you safe, additionally you should discharge the capacitor Just do this first, your life is most important). 1. Read the capacitor value. The capacitor value should be printed on the side. If you are here you already know your value, yet. 2. Measure the capacitor "Length and width". This is important. When i started looking around I realized there are multiple capacitor widths, and some of them is much "skinnier" than this one. My bracket has no real way to adjust the capacitor holding without "bending it" which won't hold it well, and feels frankly dangerous. You want the thing that is sending 440V of power to be securely fastened right? Don't "make do" get something that fits right. MEASURE the LENGTH and WIDTH! As to this capacitor, honestly I will withhold my judgement. It does work, but I dont' know about the quality yet. It does have the standard "poles" (2 for the fan, 3 for the HERM, 4 for common). It's also made in China. Honestly I would feel better about it if it was made in Mexico or USA, but the few made in the USA capacitors I found were the wrong size, and once again, DON'T MAKE DO.

Replacement AC capacitor for Thermal Zone CA, thumbs up
This replaced my TZALS series 13 capacitor on my central air. The original was longer and thinner but specs match. Had to adjust the holding strap a little due to the bigger diameter but all good and ac is back up and running. It is easy enough to replace. Turn off power by safety fuse by ac or from your fuse box. Make sure old capacitor is discharged. Take a pic of wiring on old, remembering Fan and Herm wires. A 10 minute job, under $20 part that will save you $500 minimum. Good product. Works.

Be Safe during Installation!
Good capacitor works as described

Recommend it. Would buy it again. Hope I don't have to.
Fit perfectly. Installed easily. Always replace capacitor first when your A/C quits. Reasonable price. Recommended. Would buy it again. Hope I don't have to.

AC condenser unit was humming but not turning on. Matching part number was $60+ local and had to be shipped in. Found this matching VAC and uf spec unit on Amazon, got it the next day, took 15 min to install and the unit is fixed and working perfectly. Time will tell how good this one is, but for now, the house is cold and the family is cool and happy!

Bought this capacitor to replace one that had blown on my exterior AC unit. Worked well with no issues at all. Very impressed with the price and quality of the unit.

It meets the original HC98JA046D used in Carrier comfort series 3.5ton exactly. but the diameter is way too big, so I have to bend the metal clamp to allow the installation. The overnight shipping becomes next day evening shipping, otherwise the cool air could arrive half day earlier at least. Let's see how long it can hold. The previous original one worked 16 years. This cap works perfectly over the past month almost every day. The price and quality deserves a 5+ rating.
