🔧 Average AC Installation Cost Breakdown

Component	Estimated Cost
AC Unit (14–16 SEER)	$2,500 – $6,000

🏠 Factors That Influence AC Installation Costs

1. Type of System Installed

   • Standard split systems are most common and cost-effective.

   • High-efficiency systems (18+ SEER) cost more upfront but offer long-term energy savings.

2. Efficiency Rating (SEER)

   • A 14 SEER unit is more affordable but less efficient.

   • A 16–20+ SEER unit will reduce energy bills but increase upfront cost.

3. Ductwork Requirements

   • If your current ducts are in good condition, you may save thousands.

   • New or extensive duct replacement adds $2,000 to $4,000.

4. Installation Complexity

   • Homes without existing ductwork or those requiring attic/basement modifications will see higher installation costs.

5. Labor Costs by Region

   • Labor rates vary by location. Expect higher prices in urban areas or regions with HVAC technician shortages.

6. Brand and Features

   • Premium brands like Lennox, Carrier, and Trane cost more but may offer better warranties, quieter operation, and smart home compatibility.
