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.
When Replacement Makes Sense
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- The furnace is 15 to 20 years old or more
- A repair quote runs past a third of the cost of a new unit
- Gas or electric bills keep climbing even though usage hasn't changed
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
- Permit and inspection fees, which the local building department sets
- BTU size, which should come from a Manual J load calculation
- Condition of the existing ductwork and any changes it needs
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
For The Woodlands we raised the national figures about 20%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.

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
- Look up utility rebates on 95%+ AFUE units before you buy.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
