How to Reduce Energy Bills with Better Windows in Leesburg, VA

How Worn Windows Raise Heating And Cooling Bills

In Leesburg, a lot of energy waste shows up at the windows first. Drafts around the frame, thin glass, worn weatherstripping, and failed seals all force the HVAC system to work longer than it should.

Low-E glass benefits for Northern Virginia summer heat are real, especially on exposures that get direct afternoon sun. 4.
