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 |
|---|---|
| Cooling degree days / year | 3,287 |

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.
When Replacement Makes Sense
- Gas or electric bills keep climbing even though usage hasn't changed
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- 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
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Single-stage, two-stage or modulating gas valve
- Permit and inspection fees, which the local building department sets
- Condition of the existing ductwork and any changes it needs
- BTU size, which should come from a Manual J load calculation
- New PVC venting if you move to a condensing model
We lowered the national figures about 9% for Spring 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 new furnace, filter rack and thermostat wiring
- Gas line and vent connections
- Combustion and safety tests
- 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). 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 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 Spring Homeowners
How much is furnace replacement in Spring?
Plan on $2,900 to $7,100, with most jobs near $5,200. 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 Spring?
Between late fall and early spring. With 111 days over 90°F, Spring 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.
