AC Installation Cost in Georgetown, TX (2026)

Replacing a full system in Georgetown — condenser and air handler or furnace coil — planning-bands between $8,000 and $18,000, with the typical single-system home landing near $12,500. In a climate where the equipment runs near-continuously from May into October, sizing and install quality matter more than brand.

What moves the number

• Tonnage — from a load calculation. "Same as before" sizing is how Georgetown got a generation of oversized, short-cycling systems that dehumidify poorly. Insist on the calc.
• SEER2 tier. Higher efficiency costs more up front and earns it back fastest in exactly this climate — long runtimes are where efficiency compounds.
• Ductwork condition. Leaky or crushed ducts throw away new-equipment gains; a bid that inspected the ducts is comparing honestly with one that didn't.
• Permit and inspection. Georgetown requires mechanical permits on replacements; contractors offering to skip are a red flag, not a discount.
• Two-story stock. Zoning or airflow correction for the classic hot-upstairs problem adds cost and comfort in equal measure.
