How Much Does Each Part of Central AC installation Cost?

The cost to install central air conditioning in Killeen ranges from $2,680 to $10,730, with most homeowners paying around $4,920. Your actual cost depends on several factors specific to your home and the Killeen-Temple market.

🔌
System Size (Tons)

Properly sizing the AC system is critical — undersized units run constantly while oversized units short-cycle. A Manual J calculation determines the right tonnage for your home.

Seer Rating

Higher SEER ratings (16+) cost more upfront but save significantly on electricity bills. Each SEER point above 14 saves roughly 7% on cooling costs.

📏
Ductwork Needed

If your home lacks ductwork, adding it can double the project cost. Existing ductwork may need sealing or modification for optimal airflow.

🔧
Refrigerant Type

Newer R-410A systems are standard, but some older systems use R-22 (discontinued). Upgrading refrigerant type may require a full system replacement.

🏗️
Thermostat Upgrade

A smart thermostat ($150–$300) maximizes efficiency and comfort but adds to the upfront cost. Many HVAC rebate programs require a smart thermostat.

The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
