Allen Housing Stock
The median Allen home dates to 2002, according to the Census ACS. That makes the typical house about 24 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 25,000 households here own their home, 69.8% of the occupied total. Homes here have a median value of $429,900 and households a median income of $129,130. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Collin County show 39 hail days and 27 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 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. Collin County also had 6 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.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Book maintenance twice a year, once before summer and once before winter.

Heat Pump Repair Questions from Allen Homeowners
What does heat pump repair cost in Allen?
Most bills land between $240 and $1,170, including the service call. A typical visit is about $750. 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.
