Dallas Weather and HVAC Load
NOAA's 1991-2020 climate normals put Dallas at 1,991 heating degree days and 3,124 cooling degree days per year. 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 23 nights at or below freezing and 108 days over 90°F. Snowfall averages about 2 inches. 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 | 1,991 |
|---|---|
| Cooling degree days / year | 3,124 |
| Nights at or below 32°F | 23 |
| Days above 90°F | 108 |
| Average low / high | 58.1°F / 77.9°F |
Dallas Housing Stock
The median Dallas home dates to 1980, according to the Census ACS. That makes the typical house about 46 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 42.4% of occupied homes, roughly 224,000 households. The median home value is $295,300, and median household income is $67,760. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Dallas County show 44 hail days and 30 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. Dallas County also had 4 tornado days in that period.
When Replacement Makes Sense
- Gas or electric bills keep climbing even though usage hasn't changed
- The furnace is 15 to 20 years old or more
- A repair quote runs past a third of the cost of a new unit
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
What Moves the Price
- BTU size, which should come from a Manual J load calculation
- New PVC venting if you move to a condensing model
- Condition of the existing ductwork and any changes it needs
- 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
For Dallas we lowered the national figures about 8%, 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
- The new furnace, filter rack and thermostat wiring
- Gas line and vent connections
- Removing and hauling away the old furnace
- Combustion and safety tests
- 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 Dallas. 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.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.

Furnace Replacement Questions from Dallas Homeowners

Plan on $3,000 to $7,200, with most jobs near $5,300. 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 Dallas?
Between late fall and early spring. With 108 days over 90°F, Dallas contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
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.
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.
