Common Symptoms of Window Issues

Drafts and leaks are energy drains

On a still morning or evening, run the back of your hand slowly around the sash, meeting rails, and lock while the AC is running, and feel for moving air.

A flicker test next to the weatherstrip confirms infiltration, and infiltration in Mandeville equals higher AC runtime and more indoor humidity.

Moisture between the glass

Light fog on the glass surface can be normal in our humidity, yet moisture trapped between panes confirms a broken insulating seal.

Because seal failures do not reseal, plan on replacement and consider low-E choices that keep interiors cooler and protect furnishings.

Assessing Window Operation
