How Window Orientation Affects Cooling Costs in Central Texas

Why A Few Hot Windows Can Raise The Whole House Temperature

In window installation Central Texas, the direction a window faces can matter almost as much as the window itself.

Once the room absorbs that heat, the HVAC system has to remove it later, which is why a window that looks harmless at breakfast can become a cost issue by 4 p.m.

If a room seems fine in the morning but turns stuffy every afternoon, orientation is often part of the story.
