10 Best Ac Capacitor 2025 in the United States

The VEXUNGA 45/5 uF 370/440V Dual Run Start Capacitor is designed for air conditioning units, heat pumps, and condensers. It features a dual run start, meaning it can replace both 370V and 440V capacitors, making it versatile for various applications. With a capacitance of 45/5 microfarads, it fits standard needs for many AC units.

The round shape and compact size (2.36 inches in diameter and 3.35 inches in height) make it easy to install in tight spaces. The operating temperature range from -40℃ to +70℃ ensures reliability in extreme conditions, and its compliance with US standards like EIA-456-A and UL listings speaks to its quality and safety.

The polypropylene material adds durability, and it has a safety rating of 10,000 AFC (Available Fault Current), which is a plus for safety-conscious users. However, the 6% tolerance in capacitance might be a consideration for those needing highly precise specifications. Brand reputation is solid, but as with any component, ensuring compatibility with your specific AC model is crucial. This capacitor is a good choice for those looking for a reliable, versatile, and durable component for their AC units.

The VEXUNGA 7.5uF 370/440VAC capacitor is designed for air conditioner units, pool pumps, and air condensers. It offers a capacitance of 7.5 microfarads and supports both 370V and 440V, making it versatile for different AC units. The capacitor is an oval shape, measuring 2.17 x 2.17 x 2.03 inches and weighs 3.21 ounces. Made of polypropylene and aluminum, it promises durability and reliability.

With an operating temperature range from -40℃ to +70℃, it can withstand various environmental conditions. Being compliant with stringent US standards and UL & CUL listed ensures it meets high safety and quality benchmarks. This capacitor is especially suitable for those looking to replace capacitors like the 27L566 and others mentioned in its compatibility list.

The VEXUNGA capacitor stands out for its flexibility, safety compliance, and durability, making it a solid choice for those in need of a reliable AC capacitor.

This FOCSPROD AC capacitor is a dual run type with capacitance values of 45+5 µF and a voltage rating of 370/440V, making it suitable for HVAC units, fan motors, heat pumps, or condensers that require this specific rating. It’s designed to replace common capacitor models, which makes it convenient if you need a direct swap. The capacitor's round shape and moderate size (about 2.36 inches in diameter and 3.94 inches tall) fit many standard AC units.

It operates safely in a wide temperature range from -40°C to +70°C, which covers most home and outdoor conditions. Being UL certified and built to high standards means it’s likely to last over five years, offering reliable performance. The materials used, like polypropylene and aluminum, are typical for quality capacitors. One thing to keep in mind is that it’s manufactured in China, which by itself isn’t a problem but is worth noting if you prefer products from specific origins. Also, while the ±6% capacitance tolerance is standard, it may not be ideal if your equipment needs ultra-precise values.

This capacitor is a solid choice for homeowners or technicians replacing capacitors on HVAC systems that match these specs, combining good durability, compatibility, and safety features at likely a reasonable price.
