My hot water heater went out and many companies did not get back to my inquiry. This company did came out same day, diagnosed my issue. Found that my hot water heater had a warranty for the part that was needed and called it in. When the part was delivered they came back same day and installed it. I will definitely use this company again and recommend them to everyone!
