How much does AC replacement cost?
Carrier publishes a 2026 range of $3,000–$15,000 or more including installation, but explicitly excludes a furnace, evaporator coil, and duct modifications. Treat that as a manufacturer’s broad reference for a limited scope, not the price of a complete matched system or a Temperaly quote.
For a useful budget, first establish whether the proposal replaces only the outdoor unit, both cooling components, or the heating and cooling system together. Then add any necessary duct, electrical, access, permit, and control work. A headline price without that scope cannot tell you whether your own quote is reasonable.

What does “replace the AC” actually mean?
The indoor coil and outdoor unit work together. An outdoor-unit-only price is not directly comparable with a proposal that includes a new indoor coil, air handler, or furnace. Ask the installer to document the proposed equipment match.
| Project scope | What to confirm | Why the totals differ |
|---|---|---|
| Outdoor unit only | Exact compatible indoor equipment and refrigerant requirements | Reuses more of the existing system; compatibility must be established |
| Outdoor unit plus indoor coil | Coil, connections, controls, and reuse of the existing furnace/blower | Includes work inside as well as outside |
| Cooling system plus air handler or furnace | Model numbers for every replaced component | Also replaces the equipment that moves air or provides heat |
| Replacement with duct or electrical work | Which circuits, ducts, drains, or access work are included | Adds construction and trade work to the equipment installation |

What moves a quote up or down?
Capacity, efficiency, equipment features, and installation access affect price. A variable-speed option may cost more than a basic unit; an attic installation may require more labor than easily accessible equipment. Duct changes, refrigerant lines, controls, and electrical work can be separate costs.
Ask what problem each proposed upgrade solves. A higher price might buy quieter operation or better humidity control, or simply cover necessary installation work. Separate those explanations before comparing totals. Ask for the price of optional upgrades separately so you can choose them deliberately.

Size the system for the home, then compare efficiency
Request a documented heating/cooling load calculation, such as Manual J or an equivalent method, and the matched-system rating for the proposed equipment. Do not choose capacity solely from floor area or automatically repeat the old unit’s size.
Ask the contractor to explain how the proposal addresses rooms that currently feel uncomfortable. Record the exact models and efficiency rating on your comparison sheet; a brand name or the outdoor model alone leaves important information missing.

Three illustrative budgets, with the arithmetic shown
These are invented examples for learning how to compare scope. They are not local averages, contractor offers, or predictions for your home. The equipment line below includes the indoor coil, unlike the narrower manufacturer reference above. Every example assumes a suitable equipment match; actual requirements need an assessment.
| Illustrative line item | A: straightforward replacement | B: additional site work | C: equipment upgrade and duct work |
|---|---|---|---|
| Outdoor unit and indoor coil | $4,200 | $5,500 | $7,500 |
| Installation labor and materials | $2,000 | $2,500 | $3,000 |
| Duct modifications | $0 | $1,200 | $2,500 |
| Electrical and control work | $300 | $900 | $1,200 |
| Removal, permits, and taxes (allowance) | $700 | $900 | $1,100 |
| Total before incentives | $7,200 | $11,000 | $15,300 |
Example A assumes usable existing ducts and simple access. B assumes a duct correction and additional electrical work. C assumes more expensive equipment and larger duct changes. None includes a new furnace, major electrical panel replacement, financing, or unexpected structural work. The allowances are placeholders, not fee estimates. A contractor may bundle these items differently; compare the complete scope rather than demanding this exact invoice format.
Use this checklist before comparing prices
Ask each provider to mark every item included, excluded, or still to be determined. An unexplained blank is a question to resolve before signing.
- Equipment: outdoor model, indoor coil/air handler/furnace model, capacity, refrigerant, and matched efficiency rating.
- Installation: labor, refrigerant lines, drain work, thermostat, startup testing, and cleanup.
- Site work: duct modifications, electrical circuit or panel work, access equipment, and building repairs.
- Charges: removal and disposal, permits, inspections, taxes, and any diagnostic or estimate fee.
- Protection: parts and labor warranties separately, registration requirements, and exclusions.
- Terms: deposit, payment stages, change-order approval, expected installation window, and who resolves follow-up issues.
For example, if one quote is $8,800 with electrical work excluded and another is $9,500 including $900 of electrical work, the first becomes $9,700 only if that same work really costs $900. Get the missing amount confirmed; do not assume the lower headline wins.
Will a higher-efficiency system repay the extra cost?
Compare the extra installed price with a supported annual operating-cost difference. For a hypothetical $2,400 upgrade that saves $200 per year, simple payback is 12 years. At $400 per year, it is six years. Neither saving is a forecast. Ask what electricity price, cooling demand, and equipment ratings support the estimate.
Comfort, noise, warranty, and how long you expect to stay also matter. Use the efficiency comparison calculator to vary the assumptions, or calculate the annual savings needed to justify the premium when future bills are unknown.
Compare repair and heat-pump options before committing
If the current system can be repaired, get the diagnosis and repair price in writing alongside the replacement scope. Compare both over the same period and account for the possibility of replacing the repaired system later. The repair-or-replace guide explains that comparison.
If you are also considering a heating change, request a separately scoped heat-pump option. The heat-pump basics guide explains the design questions. Keep unconfirmed rebates out of the baseline budget; verify current eligibility, application sequence, and payment timing directly with the program before relying on an incentive.
Common question
Can I replace just the outdoor unit?
Ask the installer to establish compatibility with the retained indoor equipment and identify the resulting matched rating and warranty terms. Compare that complete proposal with replacing both components. The cheaper-looking outdoor unit is not enough information to choose a system.
Common question
Is a price above an online range automatically too high?
No. First compare scope, equipment, location, and site work. Ask for the reasons behind the difference and another written proposal for the same scope when possible. An online range cannot establish the right price for a specific house.
Get a quote you can actually evaluate
Have your city and state, existing equipment details, comfort concerns, and preferred project timing ready. Request a written scope and use the checklist above when reviewing it. Start an AC replacement request. Temperaly does not set the service price; you review the provider’s scope and terms before authorizing work.
