I asked this company to replace my rental water heater as I feel paying rent monthly is not economical. The GSW water heater provided by Chin is similar to the one in big box store but provides longer warranty. Chin and his partner came on Sunday morning to install the water heater plus changing my outdated vent pipe. Entire installation process was professional and clean up after the job was completed. He also removed my old tank and returned to the rental company free of charge. Unlike the big box stores where they will charge $40 to come to perform pre-installation assessment, his price over the phone includes everything from installation to removal of old tank.
