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!

Our AC unit was making a loud buzzing noise. George from Superior HVAC Service came out and discovered a loose capacitor. He replaced it quickly, and the AC is running quietly again. Fast and efficient service!
