The Woodlands Housing Stock
The median The Woodlands home dates to 2000, according to the Census ACS. That makes the typical house 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. About 31,000 households here own their home, 71.7% of the occupied total. The median home value is $479,400, and median household income is $141,353. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Montgomery County show 10 hail days and 24 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.75 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. Montgomery County also had 4 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 The Woodlands 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 duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
