Laredo Weather and HVAC Load
NOAA's 1991-2020 climate normals put Laredo at 818 heating degree days and 4,471 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 5 nights below 32°F and 178 afternoons past 90°F in a typical year.
| Heating degree days / year | 818 |
|---|---|
| Cooling degree days / year | 4,471 |
| Nights at or below 32°F | 5 |
| Days above 90°F | 178 |

Laredo Housing Stock
Census figures put the median build year in Laredo at 1996, so a typical house here has about 30 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Laredo has roughly 48,000 owner-occupied homes, or 63.3% of households. The median home value is $182,400, and median household income is $63,264. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 7 days with damaging thunderstorm winds in Webb County. The largest hail reported was 2 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.
