Mr. H Shultz completed my plumbing inspection and did a terrific job. I didn't feel rushed and he explained everything to me very well then offered what services he suggestes be completed. I also asked him about rerouting all my water so it would be soft and he was able to complete the job extremely fast and at a price I would have probably spent more by doing it myself. Awesome company even better employees!

Hard retro fit of entirely new HVAC system in a house built in 1896. Fantastic crews, very prompt arrival and very professional. Worked hard the whole 3-1/2 days they were here. Highly recommend Tonna for both plumbing & HVAC work. You get what you pay for in their case. Some before, during and almost complete pictures . System works better than I’d had hoped for.
