Allen Weather and HVAC Load
NOAA's 1991-2020 climate normals put Allen at 2,497 heating degree days and 2,531 cooling degree days per year. Neither season dominates in Allen. That balance is a big reason heat pumps and dual-fuel systems sell well in Texas. Count on roughly 48 nights below 32°F and 97 afternoons past 90°F in a typical year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 40,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 2,497 |
|---|---|
| Cooling degree days / year | 2,531 |
| Nights at or below 32°F | 48 |
| Days above 90°F | 97 |
| Average low / high | 54.1°F / 75.9°F |
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 Permits, Efficiency Rules and Rebates
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). Plan on a mechanical permit for most replacements in Allen; the contractor normally pulls it. Before you sign, ask each bidder for their Texas license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
