How Energy-Efficient Windows Can Lower Heating and Cooling Bills in Leesburg

Why Old Windows Raise Energy Costs

Most of the time, the issue shows up as higher bills and a house that feels harder to heat in winter and harder to cool in summer.

The glass itself transfers heat, but the bigger issue is usually the leakage around aging frames, worn weatherstripping, or seals that have stopped doing their job.

When warm air escapes in the heating season, the system has to replace it. When hot outdoor air slips in during cooling season, the AC has to pull that heat back out.

Homeowners sometimes assume the problem is only the age of the HVAC equipment, but the building envelope matters just as much.
