Corpus Christi Weather and HVAC Load
Corpus Christi logs 861 heating degree days and 3,402 cooling degree days in a normal year, based on the closest NOAA weather station. 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 54 days over 90°F. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.

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. Nueces County also had 3 tornado days in that period.

Texas Licensing and Efficiency Rules
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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Texas the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask for the per-pound refrigerant price before any work starts.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
- Swap the air filter and check the breaker before you call anyone.
