Windows account for around 20 percent of your home’s energy loss in any home, so repairing leaky windows can significantly reduce your energy bills. New energy efficient windows using low-E technology reduce heat loss in winter and heat gain in summer, and filter the sun's rays which can damage furniture and carpeting over time.

 

Simply weather-stripping loose windows can save around $15 per year per window in energy costs, while making your home much more comfortable to live in. Rather than repairing your windows, you may want to consider replacing them. Government incentives on energy efficient windows may help reduce your cost.

 

Look for ENERGY STAR qualified windows, which meet or exceed US Department of Energy performance standards without sacrificing style or versatility. Today’s ENERGY STAR qualified windows are twice as efficient as the average windows manufactured just 10 years ago.

 

Poorly installed windows will cause air leaks and drafts, resulting in increased energy costs. Make sure your installer is qualified and experienced (check references) and prepared to follow the manufacturer’s installation instructions, or you may void your warranty.

 

Whether you choose to repair or replace your windows, you are taking a step in the right direction to improve your home’s energy efficiency. Your local RESNET Qualified EnergySmart Contractor is the best place to start.
