Matt Risinger and his team are always looking for a way to increase energy efficiency in their homes, both original builds and remodels. In this video, Risinger takes viewers along to switch out air compressors in one of his remodels. The original AC units are not high efficiency, and by replacing them, the homeowners will use less energy to cool their home and see a significant decrease in their electric bill—a win-win.Risinger explains the key differences between the older AC unites and their high-efficiency counterparts. The new units have two compressors, which allow them to run at different rates; low speed (3 tons) when the cooling load is low and high speed (5 tons) on days that are total scorchers, which are the norm during Texas summers.Even though these new units are high efficiency," they do take up significantly more space. New technology doesn't always mean smaller Watch the video to learn more.
