50+5 uF Dual Run Capacitor 370-440V 10 Pack - HVAC Replacement

In this review the focus is on a pack of ten TEMCo dual run capacitors aimed at HVAC technicians and DIYers who need dependable motor replacements. The bottom line: this 10 pack offers a practical, cost-effective way to swap out failing run capacitors across multiple air handlers or heatpumps, with the single biggest reason to buy being the combination of industrial construction and broad compatibility that gets systems running again quickly. The review examines build quality, installation, and value against typical OEM replacements.

Key Features

• Dual capacitance: The 50+5 uF configuration supports both motor run and start assist needs for many split system and heatpump motors, reducing the need to source separate parts.
• Wide voltage range: Rated for 370 or 440 VAC and 50/60 Hz, these capacitors cover common residential and light commercial installations for flexible replacement choices.
• Rugged construction: Heavy duty aluminum casing with a steel cap and metallized polypropylene film dielectric provide durability for HVAC environments.
• Safety and reliability: PCB-free design, 10,000 AFC protection and UL rated E335070 offer safety-focused features that installers expect.
• Quick connections: Standard 1/4 in quick disconnect terminals simplify swaps and reduce install time for technicians.
• Temperature tolerance: Operates from -40 C to +85 C, making it suitable for a wide range of climates and outdoor unit locations.

Who It's For

This 10 pack is best for HVAC contractors, maintenance teams, and homeowners who service multiple units or prefer to keep common spares on hand. The pack size and standard terminals make it particularly useful for scheduled maintenance or rapid field swaps where minimizing downtime matters.

Those seeking a single OEM-specific part or an exact diameter match for tight-fit housings should verify measurements before buying, as the unit's 1.96 in diameter and 5.58 in height may differ slightly from the original capacitor in some systems.

Pros & Cons

Pros

• High-quality industrial components give reliable performance and long-term durability for motor and blower applications.
• Easy, fast installation with 1/4 in quick disconnects reduces service time to minutes for most replacements.
• Pack of ten offers strong value for technicians and facilities replacing multiple units.
• Wide operating temperature and UL safety rating add confidence for outdoor HVAC use.

Cons

• The diameter is slightly smaller than some OEM capacitors, so users should confirm fit in cramped mounting brackets.
• Pack quantity may be excessive for single-unit homeowners who only need one replacement.
