"Authority came out to service my tankless water heater, and I?m really impressed with the experience. Chris was the technician who handled everything, and he made sure to explain how the system works and what needed to be done. He performed a thorough cleaning, checked all the components, and made sure everything was running efficiently. He was professional, knowledgeable, and took the time to answer all my questions. My water heater is running like new again! I?m very happy with the service and will definitely call them again for any future needs. Highly recommend!"
