Worst experience ever. The technician name Olivia Shoemaker with his assistant came to my house for a problem with my Navien heating system. They just asked me to turn on the hot water and then asked me to turn it off for two times. Then she told me there I no problem with my Navien heating system. How can people charge me $99 for just coming to my house to turn on my hot water and turn it off. That’s ridiculous. Don’t call them, and dont trust them, it’ll just wast of your time and money.
