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.

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.

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
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Book maintenance twice a year, once before summer and once before winter.
- Keep two feet clear around the outdoor unit, including snow.

Heat Pump Repair Questions from Dallas Homeowners
What does heat pump repair cost in Dallas?
Most bills land between $200 and $960, including the service call. A typical visit is about $620. Night and weekend calls cost more.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
