Georgetown Weather and HVAC Load
NOAA's 1991-2020 climate normals put Georgetown at 1,949 heating degree days and 2,747 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Count on roughly 28 nights below 32°F and 112 afternoons past 90°F in a typical year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 1,949 |
|---|---|
| Cooling degree days / year | 2,747 |
| Nights at or below 32°F | 28 |
| Days above 90°F | 112 |
| Average low / high | 55.2°F / 79°F |
Georgetown Housing Stock
Census figures put the median build year in Georgetown at 2007, so a typical house here has about 19 years on it. Newer homes are built tighter, so oversized equipment is a common problem. It short-cycles, wastes energy and leaves rooms clammy. Georgetown has roughly 23,000 owner-occupied homes, or 69.4% of households. The median home value is $398,600, and median household income is $91,857. We use both figures to adjust labor and pricing for this page.
Williamson County had 29 hail days and 14 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 4 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Williamson County also had 3 tornado days in that period. In Georgetown, 28.2% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

Texas Permits, Efficiency Rules and Rebates
Texas is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Equipment replacements in Georgetown generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Texas license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.

HVAC System Replacement Questions from Georgetown Homeowners
How much is full HVAC system replacement in Georgetown?
Plan on $10,600 to $23,000, with most jobs near $17,400. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule full HVAC system replacement in Georgetown?
Between late fall and early spring. With 112 days over 90°F, Georgetown contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Can I replace only the AC and keep my furnace?
Yes, as long as the indoor coil and blower work with the new AC. A mismatched system loses efficiency and can void the warranty.
How often should an HVAC system be replaced?
Most systems get replaced every 15 to 20 years. AC units and heat pumps usually wear out before gas furnaces do.
