60/12.5/440 – DUAL CAPACITOR (ROUND, MADE IN USA)
Bring the old cap in — we bench-test it free at the counter, and you'll know in two minutes whether it actually failed. Match the MFD exactly; voltage can go up (440V replaces 370V) but never down.

Symptoms of failure
- AC hums but the fan and compressor will not start
- Outdoor fan only starts if you push it with a stick
- Compressor tries to start, clicks, then trips the breaker
- System short-cycles or runs warm on a hot afternoon
- The capacitor top is domed, split, or leaking oil
- Unit worked this morning and quit in the heat of the day
Seeing these does not always mean this part is the culprit. Bring the old one in and we will meter it at the counter, free, before you buy.
If your AC won’t start, hums but doesn’t kick on, or runs but won’t cool, a bad capacitor is the most common cause. This 60+12.5 MFD dual cap powers both your compressor (60 MFD) and condenser fan (12.5 MFD) from one unit. The most common AC capacitor type.
Replaces: 60125440
Fits: Fits most residential HVAC systems using this value. Bring your old cap or model number — we match at the counter.

Installing it yourself
- Kill power at the disconnect and confirm 0V. A capacitor stores a lethal charge with the power off.
- Discharge it: bridge the terminals with an insulated-handle screwdriver, or a 20k ohm resistor, then confirm 0V with a meter.
- Photograph the wiring before you pull a single wire. HERM, FAN and C are not interchangeable.
- Loosen the mounting strap and lift the old capacitor out.
- Match MFD exactly. Voltage may go up (370V to 440V) but never down.
- Land the wires on the same terminals, strap it down, restore power.
- Never handle a swollen or leaking capacitor by the terminals - bring it in and we will dispose of it.
Power off at the disconnect first, every time. Not sure partway through? Bring it to the counter and we will walk it with you.

How do I know if my capacitor is bad?
Classic signs: AC hums but the outdoor fan won't spin, compressor won't start, or the system short-cycles. Bring it to the counter and we'll bench-test it free.
Can I use a higher MFD rating than the spec?
No. Match MFD exactly to the data plate. Higher MFD pulls more amps and will burn out your motor windings. Voltage rating can go up (440V replaces 370V), but capacitance has to match.
How long should a capacitor last?
Texas heat shortens cap life. Expect 5-7 years on a residential cap; less if your unit bakes in full afternoon sun. Cheaper imported caps fail sooner — we stock USA-made Titan HD if you want the upgrade.
Do I need to discharge it before removing?
Yes. Even an "off" cap holds a 240V+ charge that'll bite hard. Short the terminals together with an insulated screwdriver for 5 seconds before disconnecting.
