Buying Guide

Match capacitance to motor requirements

Select the exact microfarad (µF) rating specified on the existing capacitor or motor nameplate—e.g., 25 µF run or 60/5 µF dual-run—so the motor starts and runs correctly

Verify voltage and tolerance

Choose a capacitor with equal or higher rated voltage (common HVAC ratings 370–440V) and acceptable tolerance to ensure safe operation under load

Pick single vs dual run type

Use a dual-run capacitor (two capacitances in one can, e.g., 60/5 µF or 30/5 µF) when replacing combined fan and hermetic compressor caps, otherwise use a dedicated run capacitor like 25 µF

Check form factor and terminals

Confirm the physical size, mounting style, and terminal type match the mounting bracket and connector clips in your HVAC unit to avoid fitment issues

Consider brand and industrial build

Industrial-grade brands such as TEMCo Industrial offer CBB65 polypropylene construction and ratings suited for continuous motor duty, which improves longevity in HVAC applications
