Excellent, I couldn't have asked for better service from Shad. Since these systems had to be installed outside my house, Shad had to take into account the power draw on the circuits in my house, so I wouldn't overload a circuit when everything was operating. He added in an extra electrical outlet to the outside of the house from one bedroom. He also plumbed the filtered water line under a paver walkway to the greenhouse, and put the pavers back into place, as though they never moved. He also had to install a completely new hose bib, which involved welding. After that he put all the filtration system in an enclosed cabinet to protect it from the elements. He had to figure out the best position for the swamp cooler and cut, then seal a hole in the greenhouse, as well as make a level surface for the unit with pavers. Shad was extremely prompt, friendly, tidy, resourceful, and professional. He cleaned up after himself and wore shoe covers in the house. I will definitely be calling him again.
