Irving Weather and HVAC Load
Irving logs 2,220 heating degree days and 2,824 cooling degree days in a normal year, based on the closest NOAA weather station. Neither season dominates in Irving. That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. On average, Irving gets 29 freezing nights and 106 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.

Irving Housing Stock
Census figures put the median build year in Irving at 1986, so a typical house here has about 40 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Irving has roughly 36,000 owner-occupied homes, or 38.3% of households. Homes here have a median value of $287,300 and households a median income of $79,641. Those two numbers drive the labor adjustment in our estimate.
Dallas County had 44 hail days and 30 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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
- 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
- A repair quote runs past a third of the cost of a new unit
- The furnace is 15 to 20 years old or more
What Moves the Price
- New PVC venting if you move to a condensing model
- BTU size, which should come from a Manual J load calculation
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- 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
For Irving we lowered the national figures about 3%, 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
- Combustion and safety tests
- The permit and the manufacturer warranty registration
- 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). Equipment replacements in Irving generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Texas license or registration number and a certificate of insurance with the quote. 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
- 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.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
