10 Pack 45+7.5 uF Dual Run Capacitor 370-440V - HVAC Replacement

In this review the 10 pack of TEMCo 45+7.5 uF dual run capacitors is evaluated for HVAC technicians and DIY homeowners who need reliable motor and fan replacement parts. The bottom line: this kit is aimed at those who want a practical, direct replacement that restores motor start and run performance without fuss, thanks to its robust metallized polypropylene construction, UL rating, and a five year warranty that provides confidence for long term use.

Key Features

• Dual capacitance: 45+7.5 uF values give both run and auxiliary capacitance in one unit so it replaces common dual run capacitors for AC fans and blowers.
• Wide voltage range: Rated for 370 or 440 VAC, the capacitor suits a variety of single and three phase HVAC motor systems.
• Temperature tolerance: Operates from -40 C to +85 C so it withstands outdoor unit conditions and seasonal extremes.
• Durable build: Heavy duty aluminum casing with a steel cap and metallized polypropylene film improves mechanical protection and dielectric stability.
• Safety features: PCB-free construction, 10,000 AFC protection, and UL rating E335070 reduce risk and meet common electrical safety expectations.
• Quick hookup: Standard 1/4 in quick disconnect terminals make replacement straightforward and fast for technicians.

Who It's For

This 10 pack is well suited to HVAC service professionals, property managers, or hobbyist technicians who maintain multiple systems and need a consistent, reliable replacement part on hand. The pack quantity and industrial components make it a sensible option when several units require the same dual run capacitor size.

It is less appropriate for someone who needs a single, OEM-identical physical match when exact diameter is critical, since customers note the capacitor can be slightly smaller in diameter than some originals. Also, those who require capacitors with different capacitance values or nonstandard terminal types should look elsewhere.

Pros & Cons

Pros

• Works well as a direct replacement for AC units and heatpumps, restoring motor operation reliably.
• High quality internal materials and robust casing contribute to durability and safe operation.
• Easy to install with 1/4 in quick disconnect terminals, often completed in minutes by a competent technician.
• Good value for multiple replacements given the 10 pack and five year warranty.

Cons

• Some users report the diameter is slightly smaller than certain OEM parts, which can affect fit in tight housings.
• Pack size may be excessive for someone needing just one replacement capacitor.
