Why this part fails so often here
Near year-round runtimeA run capacitor is an electrolytic component that degrades with heat and with hours. Central Florida gives it both: about 3,452 cooling degree days a year against 525 heating degree days, so the compressor and the outdoor fan are cycling for most of the calendar rather than for one season.
Then there is the age of the equipment it sits in. The median residential parcel in Altamonte Springs was built in 1981 and 72.4% of the city's 13,253 residential parcels went up between 1970 and 1989. Almost none of those homes is on its original system, but plenty are on a condenser that is itself fifteen years old.

How to tell a capacitor from a compressor
The reading decides itThe symptoms overlap, which is why the price spread between the two — $150–$400 against $850–$2,400 — makes this the single most consequential diagnosis in residential HVAC.
- Humming, then nothing. The outdoor fan will not start, or starts if you nudge it. Classic weak capacitor.
- Fan spins, compressor does not. Could be the run capacitor's compressor terminal, could be the compressor. A meter settles it in a minute.
- Bulged or leaking can. Visible failure. Replace it, and check what killed it — a failing capacitor is often a symptom of a hard-starting compressor.
- Breaker trips on start. Not a capacitor story on its own.
Ask for the microfarad reading
A capacitor is rated in microfarads and is measured, not guessed. A technician who replaces one without reading it has not diagnosed anything. The reading and the rating are both stamped on the part — ask to see them.
