Port Arthur Weather and HVAC Load
NOAA's 1991-2020 climate normals put Port Arthur at 1,262 heating degree days and 3,075 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. On average, Port Arthur gets 8 freezing nights and 93 days above 90°F per year. On the cooling side, a 2,000 sq ft house here usually needs around 3.5 tons. A tight, well-insulated house may get by with half a ton less.

Jefferson County had 8 hail days and 22 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.5 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. Jefferson County also had 6 tornado days in that period.
Symptoms Worth a Service Call
- The outdoor unit hums, but the fan doesn't spin
- The system cycles on and off every few minutes
- Ice on the refrigerant lines or the indoor coil
- The breaker trips when the AC kicks on
- The AC runs, but the air coming out is warm
What Moves the Price
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
- Refrigerant type and how many pounds it takes
- Whether the equipment sits in a tight attic or on a roof
- The service call or diagnostic fee
- Nights, weekends and holidays

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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Texas license or registration number before the visit.
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.
- If you see ice, shut the system off. Running it frozen can kill the compressor.
