Cordy

This company seems to make customer satisfaction a very high priority. Last year on 10-02-24 they did the annual replacing of the numerous filters on their cleaning system at our house. Then they came by again on 10-31-24 to replace all the filters again due to the City of Laredo finding E-coli in the City's water supply. Culligan did not charge us for the replacing of all the filters in less of a month's span.Then on 10-08-25 Omar with Culligan saw that their water line was not connected to our refrigerator/Freezer and he asked if we wanted it done. Omar said there would not be any additional charges since it was supposed to be done by Culligan previously.We greatly appreciate Omar and Culligan. So many companies are dishonest and try to take advantage of customers not realizing the customers are going to stick long term with the companies that treat them honesty and fairly.
