Cedar Park Weather and HVAC Load
In a normal year, Cedar Park racks up 1,903 heating and 2,746 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. On average, Cedar Park gets 27 freezing nights and 114 days above 90°F per 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 | 1,903 |
|---|---|
| Cooling degree days / year | 2,746 |
| Nights at or below 32°F | 27 |
| Days above 90°F | 114 |

Cedar Park Housing Stock
Census figures put the median build year in Cedar Park at 2004, so a typical house here has about 22 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Cedar Park has roughly 19,000 owner-occupied homes, or 67.3% of households. With a median household income of $123,972 and a median home value of $474,800, local labor rates come out above the national middle in our model.
NOAA storm reports for Williamson County show 29 hail days and 14 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 4 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. Williamson County also had 3 tornado days in that period.
When Replacement Makes Sense
- A repair quote runs past a third of the cost of a new unit
- Gas or electric bills keep climbing even though usage hasn't changed
- The furnace is 15 to 20 years old or more
- A tech found a cracked heat exchanger, or the CO detector has gone off
What Moves the Price
- 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
- Condition of the existing ductwork and any changes it needs
- Permit and inspection fees, which the local building department sets
- New PVC venting if you move to a condensing model
For Cedar Park we raised the national figures about 18%, 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
- Removing and hauling away the old furnace
- The new furnace, filter rack and thermostat wiring
- Gas line and vent connections
- The permit and the manufacturer warranty registration
- Combustion and safety tests
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 Cedar Park. 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
- Look up utility rebates on 95%+ AFUE units before you buy.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.

Furnace Replacement Questions from Cedar Park Homeowners
How much is furnace replacement in Cedar Park?
Plan on $3,800 to $9,200, with most jobs near $6,800. 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 Cedar Park?
Between late fall and early spring. With 114 days over 90°F, Cedar Park 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.
