Pasadena Housing Stock
The median Pasadena home dates to 1976, according to the Census ACS. That makes the typical house about 50 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 54.2% of occupied homes, roughly 27,000 households. Homes here have a median value of $193,600 and households a median income of $64,270. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 28 hail days and 44 days with damaging thunderstorm winds in Harris County. 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.

- The pilot or ignition keeps failing
What Moves the Price
- A new chimney liner or venting
- A combi boiler that also makes your hot water
- Condensing or non-condensing boiler
- Fuel type: gas, oil or propane
- Pumps, zone valves and the piping around the boiler
We lowered the national figures about 18% for Pasadena using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

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). Plan on a mechanical permit for most replacements in Pasadena; the contractor normally pulls it. Before you sign, ask each bidder for their 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.
- A combi boiler frees up space and replaces your water heater.
- For a steam system, hire a contractor who works on steam regularly.
