TEMCo 70+5 uf 370-440 VAC Round Dual Run Capacitor - HVAC Replacement

Our review of the TEMCo 70+5 uf 370-440 VAC Dual Run Capacitor finds it best suited for technicians and DIYers who need a direct, reliable replacement for HVAC motor capacitors. The single biggest reason to buy is its practical combination of correct electrical ratings and heavy-duty construction: a polypropylene metallized film core in an aluminum case with a steel cap and vegetable oil dielectric offers a straightforward, PCB-free replacement with a 5 year warranty. Installation is simple for those familiar with motor capacitors and the unit is designed to fit common OEM footprints.

Key Features

• Voltage range: 370-440 VAC covers common HVAC single and three phase applications so you can replace a wide range of OEM capacitors without worrying about voltage mismatch.
• Capacitance: 70+5 uf provides both run and start assistance where systems require a dual value, reducing the need to source separate parts.
• Construction: Metallized polypropylene film with vegetable oil filling and a heavy duty aluminum casing delivers robust insulation and physical protection for long-term service.
• Terminals: 1/4 in quadruple QCT terminals (four terminals per post) make wiring straightforward and compatible with common motor harnesses for a quick swap.
• Safety and ratings: 10,000 AFC protection and UL E335070 rating mean the capacitor meets industry safety expectations for HVAC replacements.
• Warranty: The no-hassle 5 year warranty gives added confidence for installations where downtime or repeat visits are costly.

Who It's For

This capacitor is aimed at HVAC technicians, maintenance teams, and experienced DIYers who need a direct OEM-style replacement for air conditioner or motor run capacitors. It fits applications that call for a dual run capacitor with a 70+5 uf value and a 370-440 VAC rating, and it is convenient when a quick field replacement is required.

Less technical users who lack experience with high-voltage components should seek professional installation because capacitors store charge and require safe handling. Also, if a system needs a different capacitance or a radically different physical footprint, choose a part that exactly matches the OEM label rather than adapting this unit.

Pros & Cons

Pros

• Solid build quality with polypropylene metallized film and a robust aluminum case for durable service.
• Designed for easy replacement with standard 1/4 in QCT terminals and an OEM-friendly round footprint.
• Safety-minded features including PCB-free construction, 10,000 AFC protection, and UL rating.
• Five year warranty provides peace of mind for installers and building owners.

Cons

• Reported lifespan varies in customer feedback, with some units failing sooner than others, so real-world longevity can be inconsistent.
• Physical size (2.48 in diameter by 5.9 in height) may not fit every enclosure or OEM bracket without checking dimensions first.

Frequently Asked Questions

Is this capacitor safe for HVAC replacements?
This unit is PCB-free, 10,000 AFC protected and UL rated, making it suitable for HVAC motor replacement when the electrical specs match.

Will it fit my existing capacitor bracket?
It uses a common round footprint (2.48 in diameter, 5.9 in height) but buyers should confirm the enclosure and mounting hardware will accept those dimensions.

Can I install it myself?
Experienced DIYers can install it, but because capacitors store high voltage charge, anyone unsure of safe handling should hire a qualified technician.
