Farrell AC cost guide

AC capacitor replacement: what should you budget?

The capacitor gives the compressor and the outdoor fan motor the push they need to start and keep running. When it fails, the outdoor unit hums, clicks or will not start. This range is the replacement part installed. The diagnostic service call is billed with it.

Compare the right work

What are you paying for?

Dual run capacitor

$300–$380

Thirty-nine reviewed at current catalog prices, $302.80 to $375.87. Most outdoor units in our area use one dual capacitor for both the compressor and the fan motor.

Single run capacitor

$295–$335

Four reviewed, $299.55 to $331.30. Some units use a separate capacitor for the compressor or for the fan motor.

Hard-start capacitor or start kit

$380–$585

Two reviewed: a start capacitor at $382.97 and a relay and start capacitor kit at $582.55. Two jobs is a small sample, so ask for the written price.

Typical daytime visit total

$390–$460

Fifteen of eighteen reviewed daytime visits that billed only a capacitor and the $90 service call totaled $392.80 to $457.82.

Read the scope before comparing prices.

What the work covers

  • A replacement capacitor matched to the microfarad (MFD) and voltage rating of the failed part.
  • Removing the failed capacitor, wiring in the new one and checking that the outdoor unit starts and runs.

What may be separate

  • The diagnostic service call: $90, or $195 after hours and on weekends.
  • A failed contactor, fan motor or compressor found on the same visit.
  • A hard-start kit, which is a different part from a run capacitor.

What changes the price?

  • A dual capacitor that serves the compressor and the fan, or a single capacitor.
  • The microfarad rating and whether an economy or standard part is used.
  • A daytime or after-hours visit, and any other failed parts.

Behind the planning guidance

How we checked the prices.

We reviewed 51 completed jobs from July 1 through October 10, 2026 that billed a replacement capacitor. Thirty-nine dual run capacitors at current catalog prices ran $302.80 to $375.87, with a median near $331. Four single run capacitors ran $299.55 to $331.30. Six older catalog lines at $225 and one capacitor fitted during a motor change at $181.22 were left out of the headline, along with warranty parts. Eighteen daytime visits billed only the capacitor and the $90 service call, and fifteen of those totaled $392.80 to $457.82. The display is rounded outward.

51 distinct completed records were reviewed for this service. Subgroups have smaller samples, as described above. This is a selected scope review, not a statistical average. We do not publish customer details. A historical discount or an older price is not a current promotion.

Questions worth asking.

01How do I know the capacitor is the problem?

Common signs are an outdoor unit that hums while the fan does not spin, a unit that clicks and will not start, or warm air from the vents while the indoor fan runs. A swollen or leaking capacitor can sometimes be seen, but a meter test confirms it. A bad contactor or fan motor can cause the same symptoms, which is why we test before replacing parts.

02Is the service call included in the capacitor price?

No. The ranges above are the capacitor installed. The residential service call is $90, or $195 after hours and on weekends, and it shows as its own line on most of the invoices we reviewed.

03Can I replace an AC capacitor myself?

A capacitor holds a charge after the power is off and can give a serious shock. The new part also has to match the microfarad and voltage rating of the old one. We recommend leaving it to a licensed technician.

04Why do capacitors fail so often in Florida?

Heat and power surges. The capacitor sits inside the outdoor unit, so months of high temperatures and summer lightning storms wear it down. It is one of the repairs we see most often from June through September in Pasco and Hernando County.
