Overview

How Much Does AC Installation Cost in 2026

A typical central AC project costs around $5,900 to $6,000, while simpler installations can cost less and projects involving new ductwork or substantial modifications can exceed $10,000. Homes with suitable existing ductwork usually cost less to equip with central air than homes that need a new air distribution system.

Cost Item	Typical Cost
Central AC installation	$3,800 to $7,900
Central AC equipment	$2,500 to $4,500
Installation labor	$500 to $2,500
New ductwork, 300 linear feet	$3,000 to $7,500
New thermostat	$110 to $260
Basic new electrical circuit	$100 to $150
HVAC permit	About $250 to $400

AC Installation Cost With and Without Existing Ductwork

A home with serviceable supply ducts, return pathways, and accessible connections can often use the existing air distribution system and stay within the general $3,800 to $7,900 range. A home without ducts requires a larger project: new residential ductwork can cost approximately $3,000 to $7,500 per 300 linear feet, which can push total project costs above $10,000.

Labor, Electrical, and Thermostat Costs

AC installation labor can cost approximately $500 to $2,500 depending on equipment access. A basic new electrical circuit can cost around $100 to $150, though substantial modifications cost more. A new thermostat commonly costs approximately $110 to $260 for standard equipment and installation.

How It Works

How to Compare AC Installation Quotes

Compare the complete scope rather than the final number alone.

Check Equipment Capacity and SEER2

Confirm the quoted capacity matches a load calculation, and compare SEER2 ratings across quotes.
Compare Indoor and Outdoor Components

Verify the condenser and evaporator coil form a certified matched combination.
Review Ductwork Scope

Identify whether the quote assumes existing ducts stay or includes new duct installation.
Confirm Electrical and Thermostat Work

Check whether circuit, breaker, or thermostat upgrades are included or billed separately.
Review Drainage, Permits, and Removal

Confirm condensate drainage, permit fees, and old equipment removal are itemized.
Compare Total Installed Price

Only compare quotes once the full scope of labor and materials is understood.

FAQ

Frequently Asked Questions

How much does a new central AC cost in 2026?

A typical central AC installation costs about $3,800 to $7,900. Many projects fall around $5,900 to $6,000, while new ductwork or substantial modifications can push the total above $10,000.

How much does a 3 ton AC system cost?

A 3 ton system provides approximately 36,000 BTUs per hour of nominal cooling capacity. Equipment can cost roughly $3,000 to $4,200, while labor and other installation requirements increase the complete project price.

How much does new AC ductwork cost?

New ductwork can cost approximately $3,000 to $7,500 per 300 linear feet. Home layout, duct material, accessibility, and the number of supply and return runs affect the final amount.

How much does AC installation labor cost?

Installation labor can cost approximately $500 to $2,500 for many projects. Difficult access, duct modifications, electrical work, and new refrigerant lines can increase labor requirements.

Can central AC installation cost more than $10,000?

Yes. Projects involving complete new ductwork, electrical upgrades, higher cost equipment, or difficult installation conditions can exceed $10,000.

Is a new thermostat included in AC installation cost?

Thermostat inclusion depends on the contractor and project scope. A new thermostat commonly costs around $110 to $260, while advanced controls can cost more.
