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 West Allis, WI average $70,230 a year against a U.S. mean of $64,780 — a factor of 1.084 — so the labor half is scaled by that and the material half is not. Source: BLS OEWS May 2025 for the Milwaukee-Waukesha, WI metro area, SOC 49-9021.
- 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. 88°F summer and -2°F winter at Gen Mitchell International Airport — 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 $7,784 quote into a $9,730 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.

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 $5,604 – $11,832, that is not automatically wrong — but it is the question worth asking out loud.
