AC installation cost by system.
Installed pricing for Keller, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Keller, Texas, where the median home was built in 1998 and summer cooling demand is high, AC installation is a common upgrade. Typical costs for a like-for-like central AC replacement range from $4,000 to $8,100+, while a new system with ductwork runs $6,100 to $13,200+. Ductless mini-splits and heat pumps are also options, with heat pumps qualifying for federal tax credits. All work must be performed by a TDLR-licensed contractor who pulls the required mechanical permit. Given Keller's hot-humid climate and high homeownership rate (81.1%), investing in a high-efficiency system can improve comfort and energy savings.

Recommended unit for Keller
Given Texas’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Keller homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

- Good to know—

Permit and Code Compliance
Texas requires a mechanical permit for AC installation, and only a TDLR-licensed contractor can pull it. Unpermitted work can lead to fines or issues during home sale.
Refrigerant Transition
As of 2025, R-410A is being phased down in favor of R-454B or R-32. New installations must use the approved refrigerants, which may affect system selection and cost.
Older Ductwork
Many Keller homes built in 1998 have aging ductwork that may need replacement or sealing to ensure efficient operation, adding to the overall project cost.
