NOAA's 1991-2020 climate normals put Harlingen at 542 heating degree days and 4,438 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. Freezing nights are rare here, but a normal year brings 151 days over 90°F.

Harlingen Housing Stock
Census figures put the median build year in Harlingen at 1987, so a typical house here has about 39 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Harlingen has roughly 15,000 owner-occupied homes, or 57.4% of households. With a median household income of $55,891 and a median home value of $125,700, local labor rates come out below the national middle in our model.
NOAA storm reports for Cameron County show 4 hail days and 21 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Cameron County also had 6 tornado days in that period.
