Window replacement costs in McAllen

McAllen moved into a hotter climate zone in the last round of the energy code. The 2021 map shifted Hidalgo County from zone 2 into zone 1, and in a climate like that your glass mostly has one job: keeping the sun's heat out of the house.

Storms reach this far inland, too. When Hurricane Hanna came ashore on Padre Island in July 2020, McAllen's airport logged a gust of 52 knots, about 60 mph, and 12.50 inches of rain was measured in McAllen. The National Hurricane Center reported widespread power outages, including 150,000 homes in Hidalgo County, and flash flooding that took numerous water rescues. Rain driven sideways by that kind of wind tests every seal around an old frame.

Texas's own rulebook hasn't followed the map. Texas has kept the 2015 International Residential Code's energy chapter as its house standard since September 1, 2016, and that edition's climate map put Hidalgo in zone 2. Unless a city adopts something newer, the efficiency floor for a McAllen window was set for a milder label than the one the county now carries. Meeting the floor and suiting a zone 1 summer aren't the same test.
