Mission Weather and HVAC Load
NOAA's 1991-2020 climate normals put Mission at 453 heating degree days and 4,989 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 177 days over 90°F.

Mission Housing Stock
Half the homes in Mission were built before 2000 (Census ACS median), so the typical house is about 26 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 71.5% of occupied homes, roughly 20,000 households. Homes here have a median value of $160,800 and households a median income of $60,813. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Hidalgo County show 9 hail days and 19 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 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. Hidalgo 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). 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
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Maintenance plans often put members first in line for emergency calls.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
