Arlington Weather and HVAC Load
In a normal year, Arlington racks up 2,126 heating and 2,823 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Arlington. That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. Count on roughly 36 nights below 32°F and 106 afternoons past 90°F in a typical year. 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 | 2,126 |
|---|---|
| Cooling degree days / year | 2,823 |
| Nights at or below 32°F | 36 |
| Days above 90°F | 106 |
| Average low / high | 56.3°F / 77.4°F |
Arlington Housing Stock
Census figures put the median build year in Arlington at 1985, so a typical house here has about 41 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 77,000 households here own their home, 54.8% of the occupied total. With a median household income of $73,519 and a median home value of $276,400, local labor rates come out near the national middle in our model.
NOAA storm reports for Tarrant County show 58 hail days and 38 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 5 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. Tarrant County also had 3 tornado days in that period.

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 Arlington; 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
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Get one quote for a heat pump system and one for a furnace plus AC.
