How Much Does HVAC Replacement Cost in Georgetown TX?
Georgetown homeowners replacing a full HVAC system in 2026 should expect to budget $5,500-$12,000 for a complete split system installation (air handler/furnace + outdoor condensing unit), depending on system size, SEER rating, and installation complexity. Here's a realistic breakdown of what drives cost in Williamson County.
What's Included in a Full HVAC Replacement
A proper HVAC replacement is more than "swap the equipment." What a legitimate installation includes:

- Equipment: Outdoor condensing unit + indoor air handler or furnace coil cabinet
- Refrigerant line set: Existing line sets can often be reused if in good condition; new line sets add $200-$600
- Electrical: Disconnect box, wiring inspection, breaker verification
- Condensate drain inspection and repair: Georgetown's hard water often requires drain line replacement at change-out time
- Manual J load calculation: Proper sizing verification, not just replacing with the same size
- City of Georgetown mechanical permit: Required by code; failure to pull permits creates insurance and resale issues
- TDLR-licensed installation: Required for all Texas HVAC work
- Equipment registration: 10-year manufacturer warranty requires registration within 60 days of installation
- Startup and commissioning: Refrigerant charge verification, airflow measurement, thermostat calibration
Georgetown HVAC Replacement Cost by System Size
Georgetown homes range from 1,200 sq ft cottages in Old Town to 4,000+ sq ft homes in Sun City and Wolf Ranch. Approximate installed costs:
- 2-ton system (800-1,100 sq ft): $5,500-$7,500
- 3-ton system (1,200-1,800 sq ft): $6,500-$8,500
- 4-ton system (1,800-2,400 sq ft): $7,500-$10,000
- 5-ton system (2,400-3,200 sq ft): $9,000-$12,500
- Two-stage/variable speed systems: Add $1,000-$2,500 to above ranges
These ranges assume standard single-story attic installations common in Georgetown. Challenging access (cramped attics, two-story homes with indoor handler on second floor, difficult line set routing) adds $300-$600.
SEER Rating and Georgetown TX: What Actually Makes Sense
A 16 SEER system costs approximately $800-$1,200 more than a 14 SEER system of the same capacity. At Georgetown electricity rates (approximately $0.13/kWh in 2026), the payback period on the efficiency premium runs 5-8 years for typical Georgetown usage patterns.
Our honest recommendation: 16 SEER is the sweet spot for most Georgetown homeowners. The jump from 14 to 16 SEER provides meaningful utility savings with reasonable payback. The jump from 16 to 20 SEER has much longer payback periods and introduces additional complexity (variable speed compressors) that increases service cost when problems occur.
What Drives Cost Variation Between Georgetown Contractors
You'll receive quotes that vary by $1,500-$3,000 for the same job. Here's why:
- Equipment brand and tier: Budget brands vs. Carrier, Trane, Lennox. Mid-tier brands (Rheem, Heil, Goodman) offer good value at 10-20% below premium brands.
- Whether the quote includes a Manual J load calc: Low-ball quotes often skip this and "match" the existing system size, which may be wrong.
- Permit fees: Georgetown mechanical permits run $100-$200. Contractors who don't permit their work save this but expose you to code compliance issues.
- Line set handling: Reusing old line sets is cheaper; new line sets are sometimes necessary and should be disclosed upfront.
- Warranty labor coverage: Some quotes include a 2-year labor warranty; others cover only manufacturer equipment warranty.
Timing Your Georgetown HVAC Replacement
Spring (February-April) and fall (October-November) are the best times to schedule non-emergency HVAC replacement in Georgetown. Demand is lower, technician availability is better, and you're not racing against extreme weather. Summer replacements are possible but require scheduling around peak service demand, in July, same-day replacements may require several days' lead time.
