Older Gilbert areas near Downtown contain more 1980s-1990s housing, while Power Ranch, Seville, Val Vista Lakes, Agritopia and other master-planned communities added large numbers of homes from roughly 2005 through 2020. Many of those builder systems are now at the point where homeowners are comparing another major repair against a full replacement.
Because Gilbert homes are often relatively modern, the best replacement may be a straightforward equipment upgrade — but duct sizing, return-air capacity and the original builder installation still deserve verification before higher-efficiency equipment is selected.
