Short answer
Carrier publishes a broad national estimate of $3,000–$15,000 or more for installed central AC, with additional indoor equipment or duct changes potentially extra. A Texas home needs a written quote for its exact system and installation. Compare equipment, sizing, included work and warranties before choosing a price.
AC replacement prices are only comparable when the quotes cover the same job. An outdoor-unit replacement, a matched indoor/outdoor system, and a project with new ducts can have very different totals. This guide helps Central Texas homeowners understand those differences and prepare for an on-site estimate.

How Much Does AC Replacement Cost in 2026?
Carrier’s price guide gives a broad national installed central AC estimate of $3,000–$15,000 or more. It says a furnace, evaporator coil and duct modifications can add expense. This is manufacturer budgeting guidance, not a survey of Texas prices or a Kimco quote.
A useful local price comes from evaluating your home and listing the equipment and work included. Confirm whether the quote is for the outdoor unit alone, an indoor/outdoor combination, or cooling and heating together. A lower price can simply mean a smaller scope.
| Replacement scope | What to confirm in the quote |
|---|---|
| Outdoor AC unit | Compatibility with the existing indoor coil, controls and refrigerant |
| Matched central AC system | Exact outdoor and indoor model numbers, capacity and system efficiency |
| AC plus heating equipment | Whether the furnace, air handler or heat pump and backup heat are included |
| Duct or electrical changes | Which repairs, circuits, connections and controls are included or additional |
| Ductless system | Number of indoor zones, their locations and the outdoor-unit combination |
What Moves the Installed Price?
Equipment and comfort features. Compare the exact models, capacity, SEER2 efficiency, sound information and control requirements. Compressor staging and efficiency are separate specifications; a SEER2 number alone does not tell you every feature.
Installation access and existing components. Attic access, indoor-coil condition, the refrigerant line, electrical supply, condensate drainage and the outdoor location can change the scope. Have the installer explain what can be reused and what must change for the selected equipment.
Ducts and airflow. Rooms that cool unevenly can have a duct or airflow problem. Ask whether the existing ducts have been evaluated before assuming that a larger AC will fix the house.
Permits, completion checks and disposal. Ask who handles applicable local permits and inspections, removal of old equipment and the checks performed after installation. The written scope should identify exclusions and any work by another trade.
What Size AC Does a Texas Home Need?
Square footage alone cannot determine the right capacity. A load calculation considers the home’s windows, insulation, air leakage, orientation and other characteristics. Ask for the sizing basis and how the selected equipment fits it, rather than copying the old unit’s tonnage.
ENERGY STAR’s installation guidance recommends sizing from the actual home, checking airflow and refrigerant charge, and evaluating ducts. Oversized equipment can cycle too frequently and affect comfort and service life.
Which Efficiency Level Is Worth Buying?
Compare the extra purchase cost with an operating-cost estimate for your home, utility rate and cooling usage. Ask about humidity control and noise as well as energy use. Higher efficiency can reduce energy consumption, but there is no single payback period or best SEER2 rating for every Texas household.
Have the contractor confirm that the selected equipment combination meets current regional efficiency and refrigerant requirements. The outdoor model’s advertised maximum efficiency may differ from the rating of the combination installed in your home.
Repair or Replace the AC?
| Situation | Question to ask before deciding |
|---|---|
| One diagnosed component failure | What does repair cost, and is any part or labor under warranty? |
| Repeated breakdowns or major component failure | How does a complete repair compare with a complete replacement quote? |
| Uneven cooling or high humidity | Is the cause equipment, sizing, ducts, controls or airflow? |
| Older system still working | What condition and maintenance findings justify replacing it now? |
Age helps with planning, but it does not diagnose a failure. Request the repair option when it is practical, the replacement scope, applicable warranty terms and an explanation of the expected benefit. See our AC repair versus replacement guide for more questions to ask.
Compare Written AC Quotes
- Exact outdoor and indoor model numbers, capacity, efficiency and control type
- Sizing basis and any duct or airflow work
- Refrigerant line, electrical and condensate work included
- Permits and inspections where applicable, disposal and installation checks
- Parts and labor warranty terms, registration requirements and exclusions
- Total installed price, exclusions, payment terms and proposed schedule
Check current utility or manufacturer offers for your address and exact model before subtracting an incentive from the price. The federal Section 25C Energy Efficient Home Improvement Credit ended for improvements after 2025, according to the IRS. Do not budget a new 2026 installation using the old federal credit.

Frequently Asked Questions
How much does it cost to replace an AC unit in Texas?+
A Texas home needs a quote for its exact equipment and installation. Carrier gives a broad national installed central AC estimate of $3,000–$15,000 or more; added indoor equipment or duct modifications may cost extra. That is budgeting guidance, not a Texas price survey or a Kimco quote.
Does an AC replacement price include the furnace and ducts?+
Only if the written scope includes them. Confirm whether the price covers an outdoor unit, matched indoor/outdoor equipment, heating equipment, or duct changes. Compare the same scope before comparing totals.
What size AC unit does my house need?+
The right capacity depends on a load calculation using the home’s actual characteristics. Square footage and the old unit’s tonnage alone are insufficient. Ask about sizing, equipment matching, ducts and airflow.
Should I repair or replace my AC?+
Compare the diagnosed repair, warranty coverage, system condition, breakdown history and complete replacement scope. Age alone does not identify the fault, and comfort problems can come from ducts or airflow rather than the AC itself.
Can I use the old federal HVAC tax credit for a 2026 installation?+
The IRS says the Section 25C Energy Efficient Home Improvement Credit ended for improvements after 2025. Check current local utility and manufacturer offers separately for your address and exact equipment.
