Notes

  • Where the number comes from. The national price for a central air conditioner replacement is $2,500 per ton — central AC replacement pricing published for 2026, $1,800–$3,800 per ton installed. Labor is about 45% of that. Heating, Air Conditioning, and Refrigeration Mechanics and Installers near Sumter, SC average $53,350 a year against a U.S. mean of $64,780 — a factor of 0.824 — so the labor half is scaled by that and the material half is not.

  • Why the city matters, not just the state. Trade pay moves inside a state as much as it does between states. Crews do not commute across a state to bid a job, and materials ship at national prices either way — so a metro wage is the honest input here and a state average quietly rounds four different cities into one number.
  • Design temperatures. 95°F summer and 23°F winter at Shaw Air Force Base — the two numbers a Manual J starts from, and the reason equipment sized for one city is wrong in another.
  • What is in the price: the condenser, the matching indoor coil, a new line set where the run allows, refrigerant charge, a pad, electrical connection, permit and labor.
  • What is not: ductwork repair or replacement, a new electrical circuit or panel capacity, asbestos abatement on old duct wrap, and any drywall work. These are the lines that turn a $9,206 quote into a $11,508 invoice, so ask about each one before signing.
  • Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a per-unit average.

$9,206 is the typical number, and three bids on the same scope normally land between $6,628 and $13,993.

Why the city changes the number

About 45% of this job is labor — $4,143 of the $9,206 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

Heating, Air Conditioning, and Refrigeration Mechanics and Installers near Sumter average $53,350 a year, against a U.S. mean of $64,780. That is a factor of 0.824, so the labor half is scaled by it and the material half is not.

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $9,206 and something a quarter higher.

Use it as a bid check, not a quote

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.

If a bid lands outside $6,628 – $13,993, that is not automatically wrong — but it is the question worth asking out loud.
