10 Pack TEMCo 40+5 uF Dual Run Capacitor CBB65 - HVAC Replacement

In this review of the 10 Pack TEMCo 40+5 uF Dual Run Capacitor CBB65 the bottom line is straightforward: this pack is for technicians, HVAC hobbyists, and maintenance teams who need reliable, ready-to-install replacements for AC fan and motor capacitors. The reviewer found the primary reason to buy is dependable performance combined with industrial construction that makes swapping OEM capacitors quick and predictable. The set is aimed at direct replacement jobs where a standard 40/5 uF, 370/440 VAC, dual-run capacitor is required.

Key Features

• Dual 40/5 uF Rating: Provides the correct capacitance for both fan and motor circuits so it can replace common OEM dual run capacitors without rewiring.
• 370/440 VAC Compatibility: Rated for two common AC system voltages so one part covers multiple unit specifications.
• Wide Operating Temperature: Operates from -40 C to +85 C, making it suitable for units exposed to harsh outdoor or attic conditions.
• Durable Construction: Heavy duty aluminum casing with a steel cap and metallized polypropylene film improves physical durability and electrical stability.
• Safety and Protection: PCB-free design, 10,000 AFC protection and UL listing provide safer replacement parts for service technicians.
• Standard Terminals and Warranty: 1/4 in quick disconnect terminals simplify installation and a 5 year warranty gives added confidence.

Who It's For

This 10 pack suits HVAC repair shops, building maintenance teams, and contractors who perform regular capacitor replacements on residential and light commercial systems. The pack format is cost-effective for technicians who service multiple units and prefer stocking identical, UL-rated parts for quick swaps.

It is less appropriate for someone who needs a single, OEM-matching cosmetic replacement or who requires an exact diameter match for a cramped housing, since some customers note the capacitor diameter can be slightly smaller than original parts. For custom electrical specifications outside the listed ratings, a different specialty capacitor should be selected.

Pros & Cons

Pros

• Industrial-grade materials and UL listing mean a reliable replacement in demanding environments.
• Quick disconnect terminals and compact dimensions make installation fast and tool-friendly.
• Good value for a 10 pack that covers most common HVAC dual run capacitor needs.
• PCB-free and 10,000 AFC protected for safer end use compared with older designs.

Cons

• Some users report the diameter is slightly smaller than certain OEM capacitors, which can be a concern in tight housings.
• Pack quantity may be more than needed for a one-time homeowner replacement.

Our Verdict

The 10 Pack TEMCo 40+5 uF Dual Run Capacitor is a practical, value-oriented choice for professionals and maintenance crews who replace multiple HVAC capacitors. With durable metal construction, UL listing, and a 5 year warranty it balances cost and reliability well; buyers should confirm physical fit in their specific housings because the diameter can differ slightly from some OEM parts.

Frequently Asked Questions

Will this capacitor fit my HVAC unit?
It is designed as a direct replacement for many dual run motor capacitors, but confirm the 40+5 uF rating, voltage, and physical space since diameter can be slightly different from older OEM parts.

Can one pack cover multiple service calls?
Yes, the 10 pack is intended for technicians and shops that service multiple units and prefer stocking identical replacements.

Is this capacitor safe to use in residential systems?
Yes, it is PCB-free, UL listed and 10,000 AFC protected, making it suitable for residential and light commercial HVAC applications when installed correctly.
