How Aging Windows Raise Energy Use
In Northeast Florida, windows do more than frame a view, they affect how hard the HVAC system has to work every day.
Even when a window is not visibly damaged, weak seals and thin glass can create constant small losses that add up over time.
Northeast Florida also deals with long stretches of humidity, strong sun, and frequent temperature swings between air conditioned interiors and outdoor conditions.

New windows can make a house feel more even from room to room, which reduces the urge to keep adjusting the thermostat.
They also help with humidity, which is a major issue in this region.
