Back to clean AC in 10-15 minutes. *by D***G on May 23, 2025* Arrived as advertised, install took 15 minutes with slight learning curve for this model heat pump and it fired right up as it did two days prior!Thank you for making a quality product and it hope the long term review will reflect a decent life span!We have many 'brownouts' and had another AC unit for out next door 36 hours prior to this one. Dirty grid power or regular outages of 5+ seconds are very hard on capacitors in air conditioners!I was curious so I looked into it and ~83% of all HVAC related service calls are capacitor related...I bought two for each unit so we have one sitting in the storage room to use as a quick fix next time one goes out.It is not about the quality of the capacitor as it is the amount of abuse the component takes.Signed of poor construction are barely starting the motor from day one to swelling of the can which indicates it was barely staying sealed when the insides want to blow up.The welds are great, can is clean, connectors are strong and sized properly.It provides the needed burst of energy to get the compressor running and I hope it continues for a long time to come.Best wishes and I hope this helps. ### ⭐⭐⭐⭐⭐ Excellent Product! *by S***H on April 23, 2025* One of our three heat pumps stopped cooling on Saturday afternoon. The condenser unit fan was running along with the air handler, but the compressor on the condenser unit was not kicking on. I cut power, checked the capacitor with a meter, and determined it needed replacement. Matched up the capacitor size (30+5 MFD) and ordered this product from Amazon. It arrived on Sunday shortly after noon, and I installed the new capacitor later in the day. Restored power to the unit, which is running great and cooling again. This particular unit is a Bryant 1.5-ton heat pump split system. The new capacitor looks great and well-made, arrived quickly, and is working great. I would recommend it to others. The price is great as well, for under $20. It saved me about $300, which is about what I paid an HVAC company a few years ago to diagnose the problem and replace a capacitor on one of our other heat pumps. ### ⭐⭐⭐⭐⭐ Great Price, easy to install. *by R***E on May 2, 2025* Delivered on time. Great price compared to what an HVAC technician would charge to install it. Just make sure that you have the particulars of your existing capacitor and match them accordingly to the new one. It’s easy to install. Make sure the power is off on your Hvac system. Touch one of the leads with a metal object like a screwdriver to discharge any remaining power in the capacitor. Remove the two leads and the ground wire. Install the new capacitor connect the two wires and ground wire. Then power on the system.I know all these instructions have nothing to do with the review. I recommend this capacitor from this seller. I would buy it again. ## Frequently Bought Together - VEXUNGA 45/7.5 uF 45+7.5 MFD 370V or 440V Dual Run Start Round A/C Capacitor CBB65 CBB65B Air Conditioner Capacitors for AC Unit Fan Motor Start or Heat Pump or Condenser Straight Cool - BOJACK 1 Poles FLA 30 Amp Coil 24 VAC Air Conditioner Condenser Compressor Contactor AC Definite Purpose Contactor - BlueStars Ultra Durable 15 uf/MFD 370-440V Oval Run Start Capacitor CBB65 – Replacement for AC Motor, Condenser, and Heat Pump Air Conditioners --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/533188558-vexunga-45-7-5-uf-45-7-5-mfd-370v](https://www.desertcart.us/products/533188558-vexunga-45-7-5-uf-45-7-5-mfd-370v) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
