AC replacement costs
AC replacement cost: Installed Budget and Cost Factors
Budget for a matched cooling system and its stated job work. Bryant publishes a broad installed central AC range of $3,000 to $15,000. Angi's central AC guide gives $3,800 to $7,900. Those scopes and samples differ. Keep new ducts, panel work and open coil or line-set work outside your subtotal until priced. A home-specific written bid determines the total.

AC replacement cost starts with the scope of the swap. National guides put a central AC job in a broad range, but an outdoor unit swap is not the same job as replacing a matched indoor coil and outdoor unit. Use the source table and scope checklist below to decide which prices you can check.

AC replacement cost and the national price range
The range is a planning aid, not a menu of local offers. Both sources price the unit together with its installation. Neither lets you turn a house size into a firm price without a load and scope record.
| Source, checked October 14, 2026 | Published installed range | How to use it |
|---|---|---|
| Bryant HVAC pricing guide | $3,000 to $15,000 | Broad central AC envelope; confirm indoor scope |
| Angi central AC buying guide | $3,800 to $7,900 | National installation guide; new ducts need their own scope |
| Your written matched-system bid | Not yet known | Full models, included work and exclusions for your home |

The sources disagree on the upper part of the range. Do not average away that gap and call the result a quote. Unit type, local labor and included work can all differ. Read each guide's range in its own context.
For an editable starting point, open the central air installation cost calculator. It keeps the low and high guide envelope and shows how its typical planning point is derived. You can replace every allowance with a written amount.
Outdoor unit and coil and matched-system scope
A split system has more than the outdoor cabinet. The indoor coil, blower and controls affect its output. ACCA Manual S covers selecting a unit for the design load. A new outdoor unit should not be judged by its nameplate alone.
Ask for full model codes for both sides of the cooling system. A furnace can provide the blower while a separate coil handles cooling. An air handler can contain the blower and coil. Those arrangements create different swap jobs.
| Proposed job | Record on the bid | Budget issue |
|---|---|---|
| Outdoor unit only | Approved retained coil and controls | A low price may leave indoor work out |
| Outdoor unit and coil | Full matched model combination | Cabinet fit and drainage still need checking |
| Outdoor unit and air handler | Full indoor/outdoor models | Electrical heat or blower work may be included |
| Furnace and AC together | Furnace, coil, outdoor unit and controls | Avoid a second furnace or shared labor charge |

The same tonnage does not prove two units match. Ask for the relevant output record. If a bidder leaves the retained indoor model unnamed, mark fit open. That is useful information even before a dollar amount is available.
Capacity and AC replacement cost
Size is a design question before it is a price input. A larger unit may not fix a hot room. Duct airflow, solar gain and room loads may be the cause of uneven cooling.
Use the central AC size calculator to translate a known cooling load into units. It does not infer a whole-house load from floor area alone. ACCA Manual J describes the load method.
| Capacity field | Required unit or evidence | Price treatment |
|---|---|---|
| Design cooling load | BTU/h, with report date | Guides equipment selection |
| Nominal equipment size | Cooling tons and full model | Compare like-for-like bids |
| Sensible cooling | Heat removal at design conditions | Do not replace it with total capacity |
| Latent cooling | Moisture removal requirement | Check the selected indoor/outdoor combination |
| Unknown capacity | No load report yet | Keep a broad price envelope; no guessed tonnage |

This page does not publish a linear dollars-per-ton multiplier. The sources above are broad job guides, not a controlled table holding every other job detail constant. A size difference can also mean a different indoor coil, circuit or control package.
SEER2 and refrigerant compatibility
SEER2 is a seasonal cooling rating under a stated test method. It does not tell you the exact electricity bill for your house. A higher number may accompany more costly controls or compressor features, but the installed premium needs a real bid.
Check the rating for the exact matched set, rather than the highest figure advertised for a product family. Keep sound, staging and humidity control as separate fields. None is proved by the SEER2 number alone.
The EPA technology-transition page records refrigerant-related restrictions by unit sector. This is a reason to check the specified unit and job documents. A new refrigerant name does not prove old parts fit. There are no steps here for that work.
Labor, electrical work and removal
An installed range already includes the labor. Do not add an hourly labor estimate on top of it unless the bid states that the allowance excludes that work. The same rule applies to removal: it may be included, extra or still unknown.
| Work item | What the bid should state | If not stated |
|---|---|---|
| Electrical supply | Existing circuit accepted or priced work | Unknown, not zero |
| Line set | Retained, replaced or assessed separately | Unknown scope |
| Condensate drain | Route and included work | Unknown scope |
| Indoor coil | Model and cabinet work | Not assumed included |
| Removal | What equipment and disposal are covered | Ask for a written allowance |
| Permits | Who obtains them and how fees are treated | Unpriced until confirmed |

Outdoor access may also affect the job. A unit on a roof, narrow side passage or raised platform differs from one beside a clear path. Record those facts without inventing a fixed access premium.
Quote checklist for a cooling replacement
Before comparing totals, make one scope sheet for both bids. Record the indoor and outdoor full models. Write down the design load source, retained parts and required site work. Then mark each line included, extra or unknown.
Ask whether the price covers start-up check records. Those records show what was checked at completion, rather than proving that a unit badge meets your home's needs. Keep the bid, model records and warranty documents together.
If the furnace will remain, check the cooling scope separately from a combined swap. If the furnace also needs work, use the whole HVAC replacement guide. Do not add two full-system totals together.
FAQ
Does an AC replacement price include ductwork?
Only if the written scope says so. Existing ducts may be retained, repaired or replaced. The broad prices here do not establish which choice your home needs. Ask for the measured duct scope and a separate amount where required. Keep that line outside the subtotal while its status is unknown.
Can I replace just the outdoor unit?
A written bid needs to name the indoor unit that will remain and the approved combination. The outdoor nameplate alone cannot prove the match. Check the full unit and control records before judging the price. This page does not provide installation or refrigerant handling steps for carrying out the swap.
Is a higher SEER2 rating always worth the price?
The rating alone cannot settle that choice. Check the installed premium, expected cooling use and local electricity rate for the same comfort needs. Keep control and repair obligations in the check. A family maximum is not a bill-savings promise, and a national cost range cannot prove a home-specific payback.
Should I replace the furnace with the AC?
Compare a cooling-only bid with a clearly itemized combined bid. Record the furnace state, coil match and shared job scope. A combined project may avoid some repeated work, but the saving must be stated in the quote. Do not invent a package discount or count the shared coil twice.
Verdict: compare AC replacement cost by matched scope
Use the national ranges to start the budget, then replace them with written equal-scope allowances. Match the load, indoor unit and outdoor unit first. For a home adding cooling rather than replacing it, use the central air installation cost guide. Return to the furnace replacement cost calculator for a combined heating and cooling worksheet.
