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, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 23 nights at or below freezing and 108 days over 90°F. Snowfall averages about 2 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3.5 tons. A tight, well-insulated house may get by with half a ton less.

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.

Symptoms Worth a Service Call

  • The system cycles on and off every few minutes
  • Water pooling around the indoor unit
  • The AC runs, but the air coming out is warm
  • Ice on the refrigerant lines or the indoor coil
  • The breaker trips when the AC kicks on

What Moves the Price

  • Nights, weekends and holidays
  • The service call or diagnostic fee
  • Refrigerant type and how many pounds it takes
  • The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both
  • Whether the equipment sits in a tight attic or on a roof

For Dallas we raised the national figures about 13%, 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

  • Replacing the failed part
  • Checking refrigerant pressures
  • Diagnosis and electrical testing
  • Clearing the drain line if it's clogged
  • A test run

Texas Licensing and Efficiency Rules

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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Texas the company should carry a state license or registration. Ask for both.

Before You Hire

  • Ask for the per-pound refrigerant price before any work starts.
  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
  • If you see ice, shut the system off. Running it frozen can kill the compressor.
