When we moved into our new home, there was a Culligan water system already in place but we didn't know exactly how it was being used. We also noted that the water had a very distinct, unpleasant odour. We contacted Culligsn and were assigned Matthew. He was very pleasant, knowledgeable and explained everything clearly when he came to visit us on our initial consultation. After several water tests and reviewing our existing system , he offered us suggestions to make the system more effective. We had high levels of iron and Matthew proposed an iron filter.On install day, Matthew even came back with the technician, Kyle, who was also knowledgeable and efficient, to make sure we understood how the system was running. He also set up the systems for regeneration and treatment levels.About a month after the system was installed, Matthew came back, for a third time, to retest the water and make sure that the system was functioning as intended. Matthew was again, very thorough and explained the tests he was conducting and showed the comparison between our current and initial levels of iron and total dissolved solids. He was also very hands on and emptied out the water softener tank of the previous owners' salt that had created a sludge and cleaned out the tank to further improve water treatment.Matthew is very professional, knowledgeable and helpful and has been available whenever we had questions.Thank you, Matthew!
