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

Why Old Windows Raise Energy Costs

A lot of homeowners notice the same pattern first: one room feels fine, another room never quite settles down, and the HVAC system seems to run longer than it should.

Windows are a major part of that problem because glass is much less insulating than a well-built wall, and older units often leak air around the sash, frame, or installation seam.

Even if the difference per window seems small, a house with several weak spots can lose enough conditioned air to make the HVAC work much harder than it should.

A good furnace cannot fully compensate for a house that leaks air through worn windows, and replacing equipment without fixing the weak points usually leaves money on the table.

• Does the frame design limit air leakage at the sash and corners?
• Are the performance numbers suited to a climate that needs both winter and summer protection?
• Will the window match the house and any local requirements?

Where The Savings Come From

Over time, that means the HVAC system does less work to hold a steady indoor temperature.

Rooms stop feeling chilly at the perimeter, and you may find that the thermostat setting can stay lower while the house still feels comfortable.
