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 Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in Pharr; the contractor normally pulls it. Before you sign, ask each bidder for their Texas license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
