The Best Replacement Windows for South Carolina Summers

South Carolina summers are hard on windows, especially in places like Rock Hill where heat, humidity, and afternoon storms can show up in the same week. The warning signs tend to build slowly, then become obvious once the AC is running nonstop and the windows still feel weak.
