The recent national research study looked at the cost to replace windows in a medium-sized home and how much this project would add to a home price, should the home be sold a year later.  It found that for the 20 major markets served, the average rate of the window replacement cost that was recouped was 99.2%. This 2005 research study, conducted by remodeling magazine, a Hanley-Wood, LLC trade publication utilized professional opinions of over 1600 real-estate agents and appraisers in the top remodel markets who are members of the National Association of Realtors.

In Los Angeles and Ventura County, a recent survey recorded an average heating and cooling cost savings of more than 15%.
