College Station Weather and HVAC Load
In a normal year, College Station racks up 1,545 heating and 3,169 cooling degree days (NOAA 1991-2020 normals). Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. Count on roughly 16 nights below 32°F and 117 afternoons past 90°F in a typical year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 1,545 |
|---|---|
| Cooling degree days / year | 3,169 |
| Nights at or below 32°F | 16 |
| Days above 90°F | 117 |
| Average low / high | 59°F / 79.7°F |
College Station Housing Stock
The median College Station home dates to 1998, according to the Census ACS. That makes the typical house about 28 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 35.9% of occupied homes, roughly 16,000 households. Homes here have a median value of $326,500 and households a median income of $51,776. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Brazos County show 15 hail days and 20 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2.75 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.
When Replacement Makes Sense
- A repair quote runs past a third of the cost of a new unit
- The furnace is 15 to 20 years old or more
- A tech found a cracked heat exchanger, or the CO detector has gone off
- Gas or electric bills keep climbing even though usage hasn't changed
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- Permit and inspection fees, which the local building department sets
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- New PVC venting if you move to a condensing model
- BTU size, which should come from a Manual J load calculation
- Condition of the existing ductwork and any changes it needs
For College Station we lowered the national figures about 13%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- Gas line and vent connections
- Combustion and safety tests
- The new furnace, filter rack and thermostat wiring
- Removing and hauling away the old furnace
- The permit and the manufacturer warranty registration
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 College Station; 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 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.
- Look up utility rebates on 95%+ AFUE units before you buy.

Furnace Replacement Questions from College Station Homeowners
How much is furnace replacement in College Station?
Plan on $2,800 to $6,800, with most jobs near $5,000. 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 College Station?
Between late fall and early spring. With 117 days over 90°F, College Station 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.
