I had a soft water unit installed in my house and Ryce was the tech. If every company had techs like this , i would have them do everything in my house. Just a great guy, pleasant, informative, efficient and did a great job answering every question I had. I will only hire Tonna for all my plumbing needs from now on. Thank you very much. Ryan Johnson

Today I had a great experience with Dan Draxler & Hunter Schultz. Both were knowledgeable, professional and very personable. I highly recommend them to anyone needing work done. The two worked in tandem to find and fix a leaking pipe in my finished basement ceiling after I noticed a water spot. Dan came out first to diagnose the problem and determine if it was HVAC or Plumbing causing the issue. After explaining a couple things it could be and letting me know my options, we decided to open up the ceiling. After determining it was a plumbing issue, we got the Tonna office on the line and Hunter was immediately dispatched to my home. Dan prepared the workspace and even stayed to explain the situation before handing off the job to Hunter to fix the leaking pipe. Altogether the problem was diagnosed and resolved within a couple hours. Thanks for a job well done guys, you are both assets to the Tonna Mechanical team!!
