I purchased a top of the line Rinnai tankless water heater from this store. They not only had the best price compared with any other supplier I could find but also helped me save money by letting me know about a manufacturing rebate program Rinnai had in place until the end of that month. This meant I purchased the unit one month earlier than needed by my contractor but for similar price to a lower capacity unit. The owner(Belinda) was very friendly over the phone and also during my visit to their showroom. I also purchased an accessory there(pipe cover plate) that was only installed at the end of my construction work(or 5 months after initial purchase). When that box was opened I noticed it was bent. I think it was delivered like that but I can not assure it was not my contractor that damaged the unit. In any case, I called Belinda and she explained to me that since it had passed 5 months she would not be able to return the accessory back to the manufacturer but she did accepted the return and provided me a brand new replacement. I could not ask for more! I would do business again with Supergreen and Belinda anytime!
