Summer heat crisis explained: your AC is properly sized for your home WITHOUT considering solar heat gain through windows. Modern homes have 30-40% more glass than 1990s homes but AC sizing didn't change. West/south-facing rooms become heat traps—furniture hot to touch, bedrooms sleep-awful, living rooms unusable 2-6pm. Our summer cooling guide shows the math: 100 sq ft west-facing glass = 20,000 BTUs hourly heat gain (afternoon), typical bedroom AC capacity 5,000-8,000 BTUs, math doesn't work (heat exceeds removal capacity). Solar film solution: blocks heat at entry point, reduces load to manageable levels, AC sized correctly once windows controlled. Article includes room-by-room heat gain calculations and film ROI timeline. Stop fighting physics—control heat at source.
