Energy efficient windows

If you're looking to reduce your energy bills and improve your home's comfort, upgrading to energy-efficient windows is one of the smartest investments you can make. Here's how new windows can save you money.

The Real Cost of Old Windows

Old, single-pane windows are one of the biggest sources of energy loss in homes. They allow heat to escape in winter and let hot air in during summer, forcing your HVAC system to work overtime. This can account for up to 30% of your heating and cooling costs.

How Energy-Efficient Windows Work

Modern energy-efficient windows use several technologies to minimize heat transfer:

  • Double or Triple Pane Glass: Multiple layers of glass with insulating gas between them
  • Low-E Coatings: Invisible coatings that reflect heat while allowing light through
  • Insulated Frames: Vinyl or fiberglass frames that don't conduct heat
  • Warm Edge Spacers: Reduce heat transfer at the edge of the glass

Expected Savings

According to the Department of Energy, replacing single-pane windows with ENERGY STAR certified windows can save you $126-$465 per year on energy bills. For double-pane windows, savings range from $27-$111 annually. Over the 15-20 year lifespan of quality windows, that adds up significantly.

Tax Credits Available

The federal government offers tax credits for energy-efficient home improvements, including windows. You may be eligible for credits up to $600 for qualifying window installations. Ask us about current incentives!

Beyond Energy Savings

Energy-efficient windows offer additional benefits:

  • Reduced outside noise for a quieter home
  • Less UV damage to furniture and flooring
  • Improved home comfort with fewer drafts
  • Increased home value and curb appeal
  • Reduced condensation and moisture issues
