College Station Weather and HVAC Load
In a normal year, College Station racks up 1,545 heating and 3,169 cooling degree days (NOAA 1991-2020 normals). 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 16 nights below 32°F and 117 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 | 1,545 |
|---|---|
| Cooling degree days / year | 3,169 |
| Nights at or below 32°F | 16 |
| Days above 90°F | 117 |
| Average low / high | 59°F / 79.7°F |
College Station Housing Stock
The median College Station home dates to 1998, according to the Census ACS. That makes the typical house about 28 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 35.9% of occupied homes, roughly 16,000 households. Homes here have a median value of $326,500 and households a median income of $51,776. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Brazos County show 15 hail days and 20 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2.75 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.

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). Plan on a mechanical permit for most replacements in College Station; the contractor normally pulls it. Before you sign, ask each bidder for their Texas license or registration number and proof of insurance. 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.
