McAllen Housing Stock
The median McAllen home dates to 1993, according to the Census ACS. That makes the typical house about 33 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 59% of occupied homes, roughly 28,000 households. With a median household income of $60,165 and a median home value of $173,800, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 9 hail days and 19 days with damaging thunderstorm winds in Hidalgo County. 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. Hidalgo County also had 3 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 McAllen; 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
- A combi boiler frees up space and replaces your water heater.
- 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.
