Flower Mound Housing Stock

The median Flower Mound home dates to 1997, according to the Census ACS. That makes the typical house about 29 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 23,000 households here own their home, 82.3% of the occupied total. With a median household income of $157,737 and a median home value of $514,100, local labor rates come out above the national middle in our model.

Denton County had 53 hail days and 31 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 5.9 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. Denton County also had 4 tornado days in that period.

Symptoms Worth a Service Call

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

What Moves the Price

  • Nights, weekends and holidays
  • Whether the equipment sits in a tight attic or on a roof
  • 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

What the Quote Should Cover

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

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

  • If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
  • 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.
