Fulshear Housing Stock

The median home value is $546,200, and median household income is $178,398. We use both figures to adjust labor and pricing for this page.
Fort Bend County had 3 hail days and 11 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. Fort Bend County also had 2 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). Equipment replacements in Fulshear 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.
- For a steam system, hire a contractor who works on steam regularly.
