35+7.5 uF Dual Run Capacitor 370-440V - HVAC Replacement Pack

In this review a practical replacement option is examined for HVAC technicians and homeowners who need a reliable dual run capacitor. The 10 Pack TEMCo 35+7.5 uF Dual Run Capacitor is built for direct replacement of single and three phase motor capacitors and stands out for its industrial construction and safety features. The single biggest reason to buy is the combination of robust materials and UL-rated protection, which makes it a straightforward, long-term swap for worn or failing capacitors in AC fans, blowers, and motors.

Key Features

• Dual capacitance: The 35+7.5 uF split design covers common motor and fan start/run requirements so it fits many AC units and heatpumps as a direct replacement.
• Wide voltage rating: Rated for 370 or 440 VAC it works with standard HVAC circuits across regions that use either nominal voltage.
• Rugged temperature range: Operating from -40 C to +85 C ensures reliable performance in extreme attic or outdoor equipment locations.
• Safety and durability: PCB-free construction, 10,000 AFC protection and UL rated E335070 provide industry-standard safety for long-term use.
• Heavy duty build: Metallized polypropylene film with epoxidized soybean oil, inside an aluminum casing with steel cap, gives corrosion resistance and mechanical strength.
• Simple connections: Standard 1/4 in quick disconnect terminals make installation a fast job for trained technicians or experienced DIYers.

Who It's For

This capacitor pack is aimed at HVAC professionals, maintenance shops, and homeowners comfortable with electrical repairs who need a ready supply of direct-replacement capacitors for air conditioner compressors, condenser fan motors, and blower motors. The 10-pack format suits service vans and facilities that perform multiple repairs or that want spares on hand.

It is less suitable for casual buyers who will only ever replace a single capacitor and prefer an individual unit rather than a bulk pack. Also, if exact original physical dimensions are critical, buyers should verify fit in tight housings since some customers noted a slightly different diameter than their OEM part.

Pros & Cons

Pros

• Works well as a direct replacement for many OEM capacitors, restoring HVAC function quickly.
• High-quality industrial components and UL rating give confidence in safety and longevity.
• Easy to install with 1/4 in quick disconnect terminals, typically a five minute swap for a trained person.
• Good value when purchased as a 10-pack for technicians and maintenance programs.

Cons

• Physical diameter is slightly smaller than some originals, so double-check fit in tight mounting brackets or housings.
