The capacitor gives your AC motors their starting kick, and Florida heat kills more capacitors than any other part — the classic sign is an outdoor unit that hums but won't start.
Handle it soon — these get more expensive with time. A capacitor stores a serious electrical charge even with the power off. Confirming or replacing one is a job for someone trained to discharge it safely — not a screwdriver-and-video project.
Common causes:
• Years of Florida heat cooking the part inside the outdoor cabinet — a swollen, bulging top is the classic telltale
• Power surges and brownouts, which stress capacitors every storm season
• Simple age — capacitors are wear items, not lifetime parts
• A struggling fan or compressor motor overworking the capacitor until it gives out first
• A whole-new-system pitch for a failed capacitor — one of the quickest, most routine repairs in the trade
• A replacement capacitor installed without checking the motor it serves — a dying motor kills new capacitors in short order
• No parts-and-labor breakdown on the invoice
• No state license number for air-conditioning work on the estimate
What are the signs of a failed AC capacitor?
A humming or clicking outdoor unit whose fan won't spin, an AC that tries to start and gives up, warm air while the indoor blower runs, or a fan that only starts if pushed — which you should leave to a tech, not a stick.
Is replacing a capacitor a big job?
For a licensed tech it's typically quick and inexpensive as AC repairs go. The valuable part of the visit is finding out why it failed — heat and age are normal, but a weakening motor means the next failure is already scheduled.
AC repair (capacitor / fan / minor): $150–$1,200 (typical ~$400)
A compressor is the expensive failure — often $1,500–3,000+.
