Texas City Weather and HVAC Load
NOAA's 1991-2020 climate normals put Texas City at 962 heating degree days and 3,307 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 3 nights at or below freezing and 56 days over 90°F. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.
| Heating degree days / year | 962 |
|---|---|
| Cooling degree days / year | 3,307 |
| Nights at or below 32°F | 3 |
| Days above 90°F | 56 |
| Average low / high | 65.1°F / 77.6°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 It Makes Sense
- The house can't reach the thermostat setting on hot afternoons
- It still runs on R-22 refrigerant
- Summer electric bills keep going up
- The AC is 12 to 15 years old or more
What Moves the Price
- SEER2 rating and whether the compressor is single-stage or variable-speed
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- Tonnage, based on house size and local climate
- Electrical work such as a new disconnect, breaker or wiring
- Whether the coil and line set also need replacing
We raised the national figures about 8% 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.
What the Quote Should Cover
- The electrical disconnect and wiring
- The new condenser, coil and, if needed, line set
- Refrigerant charge and a leak test
- Startup, an airflow check and warranty registration
- Removing the old condenser and coil
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
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Ask for a Manual J calculation. "Same size as the old one" isn't sizing.
- Fall and early spring installs often come with better pricing and shorter waits.

AC Installation Questions from Texas City Homeowners
How much is new AC installation in Texas City?

When is the best time to schedule new AC installation 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.
How long does a new AC last?
With yearly maintenance, 12 to 17 years. Salt air and extreme heat shorten that.

It depends on square footage, insulation, windows and climate. The rough rule is a ton for every 450 to 650 sq ft, but only a Manual J calculation gives you a real number.
