Is $5,000 the price of a Tucson system?

No. HomeAdvisor says the average cost to replace a central air conditioner is about $5,000, inside a general range of $2,500–$7,500, and that the price can rise to $12,500. That is a national published range, not a proposal.

Why do ducts change the price so much?

HomeAdvisor lists installing ductwork with a new central system at $6,000–$12,000. A condenser-only swap is a different job from new attic ducts. Ask which one the quote is.

Does a higher SEER rating have its own price on this page?

No. We are not publishing an efficiency upcharge we did not cite. Efficiency, matched coils, and line set condition belong in a written estimate.

Can I subtract the TEP rebate from the HomeAdvisor range?

Not as a promise. TEP lists up to $720 for a qualifying heat pump and up to $600 for a qualifying air conditioner, only with a participating contractor. See the TEP page and confirm eligibility before you do the arithmetic.

What should a quote include?

Equipment model numbers, whether the air handler or coil is included, duct or electrical work, haul-away, and any rebate marked as conditional. A single bottom line with no scope is how people compare different jobs.

Where do I start if I already have a quote?

The second-opinion page. Bring the scope, not just the total.

People want a Tucson number for a new air conditioner before anyone has seen the closet, the roof, or the electrical panel. The honest national ranges we can cite are from HomeAdvisor’s AC repair cost guide (updated June 17, 2026), which also covers replacement:

What HomeAdvisor published	National range
Central air conditioner replacement, generally	$2,500–$7,500
Average central air conditioner replacement	About $5,000, and the page says the price can rise to $12,500
New central system plus ductwork	$6,000–$12,000

Those figures depend, in HomeAdvisor’s words, on the size of the home, the brand, and the efficiency rating, and on how complicated the ductwork is. They are not a Sabino Creek price and they are not adjusted for Tucson labor. Use them to tell a condenser swap from a whole-system job, not to budget to the dollar.

What actually changes a Tucson job

Tonnage and whether the old nameplate was ever the right size. Square footage is not a tonnage: what size AC a Tucson home needs.
Attic ducts that leak into a 140-degree attic. A new condenser does not fix that. Ducts and attic heat.
Electrical service: a breaker, a disconnect, and sometimes a panel that cannot take the new equipment.
Roof versus ground, and an HOA screen that blocks the outdoor coil.
Heat pump versus straight air conditioner plus a gas furnace. That choice is about winter heat, not a slogan.
Line set, indoor coil, and whether the quote replaces them or reuses them.

Tucson Electric Power lists instant rebates of up to $720 for a qualifying high-efficiency heat pump and up to $600 for a qualifying high-efficiency air conditioner, plus duct sealing and mini-splits. The rules and the participating-contractor requirement are on TEP rebates. Do not subtract those amounts from the HomeAdvisor range unless the job qualifies. The job-conditions page, without a second invented price list, is AC replacement cost. Installation steps are on AC installation.
