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.

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
- Ask your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
