I've used ARS two times. Once to install 14 new ball valves in all my water lines including my main line. And second, my coupler on my heater pump broke. The repair man saved me money by recommending to wait based on my problem so I wasn't paying the emergency fee. Also asked me to send him pictures to his cell so he would know my heater system and could see the components. Next day service, had parts on there truck, reasonable repair fee even bought the home protection plan. Not sure why other left such bad feedback. They must be nuts! These guys/gals are good and as of now they have me as a dedicated customer for life.
