We have been very happy with the installation process from Z&R, they have been professional, kept a clean space when they're done at the end of the work day and have kept in contact with us throughout the process making sure the work is done right and is done the way we want it (location of duct work, etc). We have been very happy from the gentleman that came to give a quote to the 2 that are doing the installation. We will recommend Zenner & Ritter to family, friends and neighbors
