My furnace started acting up, so I called Superior HVAC Service. Rameen arrived promptly, diagnosed the issue, and had it repaired in no time. He even checked my water heater to make sure everything was running efficiently. The service was reliable, hassle-free, and exactly what I needed!
Reard was so fast and clean when fixing my boiler. Great service!
I scheduled a routine maintenance check for my heating system, and I’m glad I did. Reard from Superior HVAC Service found a small leak in one of the pipes leading to my boiler that could have turned into a much bigger problem. He repaired it on the spot, checked all the connections, and tested the system to make sure everything was working safely. I really appreciated his thoroughness and the peace of mind knowing everything is in top shape. Definitely a company I trust!
