How to Tell Whether Your Windows Are Losing Energy
A window can look fine from the street and still be leaking heat, letting in drafts, or working against your HVAC system.
The clues are usually practical, not dramatic. Drafts, uneven room temperatures, fogging between panes, and rising utility bills often point to the same underlying issue.

If you see persistent clouding between the glass layers, the seal is already compromised. At that point, the window has likely lost much of the insulating value it had when new.
Temperature swings are another warning sign. Rooms with weak windows often feel overheated in the afternoon, chilly near the perimeter, or uneven from one side of the house to the other.
Sunlight can also reveal trouble. If a room gets harsh glare, faded fabrics, or a noticeable heat gain through the glass, the window may be missing low-E protection or may have older glass that was never designed for modern efficiency.
