Spring Weather and HVAC Load
Spring logs 1,266 heating degree days and 3,287 cooling degree days in a normal year, based on the closest NOAA weather station. Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. A normal year brings 10 nights at or below freezing and 111 days over 90°F.
| Heating degree days / year | 1,266 |

Spring Housing Stock
The median Spring home dates to 1991, according to the Census ACS. That makes the typical house about 35 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Spring has roughly 16,000 owner-occupied homes, or 74.8% of households. Homes here have a median value of $221,300 and households a median income of $86,888. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Harris County show 28 hail days and 44 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 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. Harris County also had 9 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). Expect the contractor to pull a mechanical permit for a replacement job in Spring. If a bidder suggests skipping it, move on. Also ask for a 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.
- Ask your gas or oil company about rebates on condensing boilers.
