text: We turned off our water heater during our vacation and when he came back we dont know how to turned it on. I called several co left a message to call me back but none of them called back except for Mario . I told him the situation and he helped me over the phone as a courtesy . Now that's a wow!!!! He didn't mind spending time helping me over the phone with no charge, you will never see that kind of courtesy at all. Mario thank you again!!! I will definitely call you and recommend you to anyone.
