Can New Windows Help Me Save Money on Energy Bills In Oregon?
By Lucas Kelly, Portland Siding Expert | February 28th, 2025
If you’re looking for ways to reduce your energy bills, upgrading your windows might not be the first solution that comes to mind. However, outdated or inefficient windows can be a major source of heat loss in the winter and heat gain in the summer, forcing your HVAC system to work harder—and driving up your energy costs. At Sister Siding, we specialize in high-quality window installations that enhance your home’s efficiency, comfort, and value. But are new windows really worth the investment when it comes to saving money?
How Do Windows Affect Energy Efficiency?
Your windows play a crucial role in regulating your home’s temperature. Old, single-pane windows or those with failing seals allow heat to escape in the winter and enter in the summer. This leads to:
- Higher heating and cooling costs as your HVAC system works harder to maintain a comfortable indoor temperature.
- Drafts and inconsistent temperatures, making some rooms feel too hot or too cold.
- Increased UV exposure, which can cause fading of furniture, flooring, and curtains.
By upgrading to energy-efficient windows, you can significantly reduce heat transfer, resulting in a more comfortable home and lower electric bills.
How Much Can You Save with Energy-Efficient Windows?
The U.S. Department of Energy estimates that replacing old, single-pane windows with ENERGY STAR®-certified windows can save homeowners:
- Up to $465 per year when replacing single-pane windows.
- 10-20% on heating and cooling costs with energy-efficient upgrades.
These savings vary based on climate, the condition of your current windows, and the type of replacement windows you choose. However, in addition to lower energy costs, new windows also increase home value, curb appeal, and indoor comfort—making them a smart long-term investment.
What Makes a Window Energy-Efficient?
When choosing new windows, look for these key features to maximize energy savings:
Double or Triple Panes
Multi-pane windows provide better insulation by trapping air or gas (like argon or krypton) between the panes to reduce heat transfer.
Low-E (Low-Emissivity) Glass
A special coating that reflects heat while still allowing natural light to enter, helping keep your home warm in winter and cool in summer.
Gas Fills
Argon or krypton gas between panes enhances insulation, reducing energy loss.
Quality Frames
Vinyl, fiberglass, or wood frames with thermal breaks help minimize heat transfer.
Proper Installation
Even the best windows won’t perform well if they’re not installed correctly. A poor installation can lead to air leaks and reduced efficiency.
