Best dual run capacitors for AC condensers
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Start with the rating, not the brand. A dual run capacitor has to match the microfarad numbers printed on your old one (e.g. 35/5, 45/5) and be rated 370/440V — the wrong value will kill the compressor or fan motor.
Top pick: EverGrow 45+5 MFD 370/440V CBB65 — the most common condenser rating, ±6% tolerance, and the one I'd trust for a straight-cool or heat-pump condenser swap.
Who the others suit:
- Seentech 35+5 or 45+5 — solid alternative if you want a second brand choice at the same ratings.
- SOTUBX 35+5 / 50+5 — for units calling for 35 or 50 µF on the compressor side.
- Titan HD 70+10 — only for larger commercial-style units.
- 20+10, 45+10, 60+7.5 — match those exact odd ratings only.
Whatever you buy: power off at the disconnect, discharge the old cap, and match µF and voltage exactly.
