If your energy bills are climbing or your home never feels comfortably warm or cool, your windows might be the culprit. In Charleston and the surrounding Lowcountry, older or poorly installed windows can quietly drain your energy—and your wallet.
In this blog, we’ll explore how to know if your windows are causing energy loss and what you can do about it.
1. You Feel Drafts, Even When Windows Are Closed
A light breeze or sudden temperature change near your windows is a warning sign. Drafts often come from worn seals, warped frames, or improper installation. These gaps let conditioned air escape and outdoor air sneak in, forcing your HVAC system to work harder.
Quick test: Hold a lit candle or incense stick near the window edges on a windy day—if the smoke moves erratically, you’ve got a leak.
2. Your Energy Bills Are Higher Than Expected
A sudden or steady rise in heating and cooling costs may indicate your windows aren’t insulating properly. Even with an efficient HVAC system, leaky windows can let all that effort escape. According to the U.S. Department of Energy, up to 30% of residential heating and cooling energy can be lost through windows.
3. Your Home Has Hot or Cold Spots
Rooms that feel like saunas in the summer or iceboxes in the winter are a clear sign your windows aren’t performing. Single-pane windows or older windows with worn seals often cause uneven temperatures.
4. Condensation or Fog Between Panes
Foggy double- or triple-pane windows usually indicate a broken seal. When the insulating gas—often argon or krypton—escapes, the window loses its effectiveness.
5. Increased Outdoor Noise
Modern energy-efficient windows help reduce noise. If traffic, barking dogs, or neighbors seem louder than before, it may signal failing window insulation and decreased energy efficiency.
6. Visible Frame Damage or Warping
Charleston’s humidity, salt air, and intense sun can damage window frames over time. Warping, rot, or water damage can lead to air leaks and even more serious issues like mold or wall damage.
7. Your Windows Are Just Old
Windows over 15–20 years old likely don’t meet modern energy standards. Today’s high-efficiency options feature multiple panes, low-E coatings, improved seals, and durable frames designed for coastal climates.
