"My toilet was not functioning correctly and i was going to call someone to fix... my son in law said call Hartman...i think they do plumbing, too. I didn't know that! Hartman has taken care of my heating/air since 2001 so i didn't even hesitate to call! Brad was great and was able to remedy the issue quickly. He was polite and knowledgeable! He also showed me where to turn my water off for future reference. Another great experience with Hartman!!"
