See Why Your Neighbors Trust L&S Plumbing
Joe helped troubleshoot an issue with me on the phone for over twenty minutes on a furnace he installed almost ten years ago. He did such a good job I was able to get it running again within an hour! I would never wish for furnace issues, but I would happily be a customer!
