10 Pack TEMCo 189-227 uF 220-250V AC Start Capacitor - HVAC

Our review of this 10 pack of TEMCo 189-227 uF motor start capacitors finds them most useful for technicians and DIYers who need a compact, economical replacement for single phase motors in HVAC, compressor, or pump systems. The biggest reason to consider this pack is straightforward: it replaces OEM start capacitors at a fraction of the cost while offering a rugged phenolic case, UL rating, and a five year warranty that together make it a practical choice for routine service work.

Key Features

• Capacitance range: The 189-227 uF rating covers a common start range so these capacitors suit a variety of single phase motor applications without needing multiple part numbers.
• Voltage and frequency: Rated for 220-250 VAC and 50/60 Hz, they match standard motor supply conditions for HVAC and compressor equipment.
• Durable construction: The electrolytic oil filled design in a rugged phenolic resin case provides reliable insulation and mechanical protection in service environments.
• Compact size: At 1.78 in diameter and 3.33 in overall height, the units fit many motor housings and replacement brackets where space is limited.
• Installation ready: Standard 1/4 in quick disconnect terminals allow fast swaps during maintenance without special adapters.
• Safety and assurance: PCB-free construction and UL rating E492933 add confidence for commercial HVAC and industrial use, backed by a 5 year warranty.

Who It's For

This 10 pack is aimed at service technicians, facility maintenance teams, and home mechanics who perform multiple capacitor replacements and want to stock a proven, low-cost replacement option. The pack format makes it economical when repairing more than one unit or when keeping spares on hand for busy seasons.

Those who should look elsewhere include users who need a specific OEM physical size match beyond the listed dimensions, or users who require capacitors with different dielectric technology or specialized mounting hardware. Also, if absolute peak longevity is critical for a bespoke application, consider OEM-specified or higher-end options.

Pros & Cons

Pros

• Good value for money when replacing multiple motor start capacitors during service calls.
• Fits many applications due to its common 189-227 uF rating and compact form factor.
