AC capacitor replacement cost in Casselberry, Florida
Replacing an AC capacitor runs $150 to $400 installed, with a national average near $250. The capacitor itself is rarely more than $45; the rest is diagnosis, the correctly rated part and safely discharging a component that holds a lethal voltage after the power is off.
These are researched market ranges, not our prices and not a quote.
The dollar figures below come from published third-party cost guides — named and linked at the foot of the page — and from the City of Casselberry’s own published permit fee. They are here so you can tell whether a quote you have been handed is in the ordinary range for this work. They are not an offer, and no two houses in Casselberry cost the same to do.

A run capacitor is a small cylinder in the condenser that gives the compressor and fan motor the phase shift they need to start and run. It is the single most common failure on a Florida condenser, because it is an electrolytic component sitting outdoors in an enclosure that spends nine months a year hot.
What the money actually buys
The gap between a $45 part and a $150–$400 bill is the question everybody actually has. What you are paying for:
- The diagnosis. A dead capacitor, a failed contactor, a seized fan motor and a tripped float switch all look identical from the thermostat. Getting it right is the work.
- The right part. Capacitors are rated in microfarads and volts and are matched to the specific compressor and fan. A generic multi-tap capacitor fitted to the wrong values will run, and will shorten the compressor’s life.
- Doing it safely. A charged capacitor holds a lethal voltage after the disconnect is pulled. This is the classic “cheap part, do it yourself” job that puts people in hospital.
The honest caveat: on a system that is already fifteen years old, a capacitor is a $250 stay of execution, not a repair. It is still usually worth doing — but do it knowing that, and read the repair-or-replace page before the next part fails.
Why this is the most common call in this city
Casselberry is a capacitor market for a specific, checkable reason. 57.1% of the city’s 8,563 improved residential parcels were built between 1970 and 1989 and the median build year is 1977. Those houses are on their third or fourth condenser, and a condenser installed in the 2000s or 2010s is now deep into the age band where the capacitor is the first thing to go. If yours has been replaced twice in three years, the capacitor is not the problem — something is overheating it, usually a failing fan motor or a condenser coil packed with debris.

Condenser humming but not spinning?
That is the classic capacitor signature. It is also what a seized fan motor does. Worth a phone call before you buy a part.
