New windows do not make a house airtight by magic, and they are not the right answer for every energy problem.

How worn windows waste energy

Most energy loss through windows comes from three sources, air leakage, poor insulation, and unwanted solar heat.

A draft at the frame, hot spots in south-facing rooms, and AC cycles that seem to run forever are classic signs that the windows are not doing their job.

Condensation between panes is another clue, especially in humid weather.
