Woke up to no hot water and immediately called Superior HVAC Service. Hunter arrived on time, quickly diagnosed the issue with my tankless water heater, and had it working again in no time. He even did a quick check on my furnace to make sure everything was running smoothly. I really appreciated his professionalism and attention to detail!
