Galveston County had 7 hail days and 17 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.75 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. Galveston County also had 4 tornado days in that period. In Galveston, 20.1% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk.

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). Equipment replacements in Galveston generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Texas license or registration number and a certificate of insurance with the quote. 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.
  • Ask your gas or oil company about rebates on condensing boilers.
  • A combi boiler frees up space and replaces your water heater.
