Round Rock Housing Stock
Census figures put the median build year in Round Rock at 2001, so a typical house here has about 25 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Round Rock has roughly 26,000 owner-occupied homes, or 56.2% of households. The median home value is $383,700, and median household income is $97,187. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 29 hail days and 14 days with damaging thunderstorm winds in Williamson 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. Williamson County also had 3 tornado days in that period.

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.
- Keep two feet clear around the outdoor unit, including snow.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.

Heat Pump Repair Questions from Round Rock Homeowners
What does heat pump repair cost in Round Rock?
Most bills land between $220 and $1,070, including the service call. A typical visit is about $690. Night and weekend calls cost more.
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.
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.
