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 in Maine average $65,300 a year against a U.S. mean of $64,780 — a factor of 1.008 — so the labor half is scaled by that and the material half is not.
  • 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 $3,764 quote into a $4,704 invoice, so ask about each one before signing.
  • Why state matters more than people expect. Materials ship at national prices; crews do not move. Maine sits above the national mean by 0.8%, which lands on 45% of the job and moves the total by $14.
  • Use this as a bid check, not a quote. It prices an average job in an 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.

A 1.5 ton AC replacement in Maine

$3,764 is the typical figure, and bids on the same scope normally land between $2,710 and $5,721. That is 2 tons at $2,509 each.

Why this is not the national number

The same job priced at the U.S. average comes to $3,750 — this one is $14 more.

Heating, Air Conditioning, and Refrigeration Mechanics and Installers in Maine average $65,300 a year against a U.S. mean of $64,780, from the Bureau of Labor Statistics OEWS release for May 2025, SOC 49-9021. That is roughly $31 an hour of trade pay, a factor of 1.008.

Labour is about 45% of this job; equipment is the other 55% and it costs the same in every state. So only the labour half is scaled here.

$1,694 of labour, $2,070 of equipment.

What moves a quote inside the range

A straight condenser-and-coil swap that reuses the line set and the pad sits near the bottom. A replacement that needs a new line set run through a finished wall, an electrical disconnect brought up to code, and a crane for a rooftop unit sits near the top.

The thing that is not in the price, and usually should be

Ductwork. A system replaced onto duct that was undersized for the old equipment performs no better than the old equipment did — and the new unit gets blamed. Ask for a static pressure reading before signing, not after.

Do not copy the old size

The unit being replaced was very likely oversized; contractors have rounded up for decades. A Manual J costs a few hundred dollars against this figure and is the only way to know whether 1.5 tons is right for the house rather than right for whatever was there before.

Using this against a real bid

Three quotes on identical scope should cluster. One well under $2,710 usually means something was left out rather than found cheaper. One well over $5,721 is either a harder job than average or a crew that does not want the work.
