STAY FAR AWAY! This company is currently under investigation for tax evasion after working with immigrant salesmen, they hired UNLICENSED plumbers on over 50 installs and work their best to con customers. They will blindside you if you give them the slightest chance. If you ever have an issue, I've been told by insiders of the company the boss Calvin Sr has told employees to tell them HES NOT AVAILABLE and will ignore your phone calls. They will change service fee on your system without notification and I was informed that NONE OF THEIR 200 CUSTOMERS HAVE HAD THEIR WARRANTIES SUBMITTED SINCE 2014. AVOID THIS COMPANY AT ALL COSTS.
