Richardson Weather and HVAC Load
Richardson logs 2,294 heating degree days and 2,612 cooling degree days in a normal year, based on the closest NOAA weather station. Neither season dominates in Richardson. That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. On average, Richardson gets 35 freezing nights and 93 days above 90°F per year. Snowfall averages about 2 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 40,000 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 | 2,294 |
|---|---|
| Cooling degree days / year | 2,612 |
| Nights at or below 32°F | 35 |

Richardson Housing Stock
The median Richardson home dates to 1985, according to the Census ACS. That makes the typical house about 41 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Richardson has roughly 23,000 owner-occupied homes, or 50.8% of households. The median home value is $405,600, and median household income is $96,257. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 44 hail days and 30 days with damaging thunderstorm winds in Dallas County. 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
- 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
- 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
- BTU size, which should come from a Manual J load calculation
- Condition of the existing ductwork and any changes it needs
- New PVC venting if you move to a condensing model
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Permit and inspection fees, which the local building department sets
- Single-stage, two-stage or modulating gas valve
We raised the national figures about 8% for Richardson 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 permit and the manufacturer warranty registration
- Combustion and safety tests
- The new furnace, filter rack and thermostat wiring
- Removing and hauling away the old furnace
- Gas line and vent connections
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 Richardson; 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
- Look up utility rebates on 95%+ AFUE units before you buy.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.

When is the best time to schedule furnace replacement in Richardson?
In spring or fall. Those are the slow months between heating and cooling season in Richardson.
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.
