Richardson Housing Stock

The median Richardson home dates to 1985, according to the Census ACS. That makes the typical house about 41 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Richardson has roughly 23,000 owner-occupied homes, or 50.8% of households. The median home value is $405,600, and median household income is $96,257. We use both figures to adjust labor and pricing for this page.

Between 2020 and 2025, NOAA's Storm Events Database logged 44 hail days and 30 days with damaging thunderstorm winds in Dallas County. 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 breaker trips when the AC kicks on
  • Water pooling around the indoor unit
  • Ice on the refrigerant lines or the indoor coil
  • The AC runs, but the air coming out is warm
  • The system cycles on and off every few minutes

What Moves the Price

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

We raised the national figures about 25% for Richardson using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

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

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). A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Texas license or registration number before the visit.

Before You Hire

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