Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. A normal year brings 3 nights at or below freezing and 56 days over 90°F.

Texas City Housing Stock
Census figures put the median build year in Texas City at 1981, so a typical house here has about 45 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Texas City has roughly 12,000 owner-occupied homes, or 53.9% of households. The median home value is $190,600, and median household income is $65,447. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Galveston County show 7 hail days and 17 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. Galveston 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
- A repair quote runs past a third of the cost of a new unit
- A tech found a cracked heat exchanger, or the CO detector has gone off
- The furnace is 15 to 20 years old or more
What Moves the Price
- Condition of the existing ductwork and any changes it needs
- Permit and inspection fees, which the local building department sets
- BTU size, which should come from a Manual J load calculation
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
We lowered the national figures about 18% for Texas City 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). Equipment replacements in Texas City 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.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.

Furnace Replacement Questions from Texas City Homeowners
How much is furnace replacement in Texas City?
Plan on $2,600 to $6,400, with most jobs near $4,700. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule furnace replacement in Texas City?
Between late fall and early spring. With 56 days over 90°F, Texas City contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
