System was serviced by Culligan for years. A-1 pointed out a fundamental flaw in the system and repaired it on the first visit that improved overall system performance

We were having problems with our water softener. After calling them for service and the reviewing the work they did, I am completely confident in the work and service they provided. They are knowledgeable and experienced and they are an excellent choice if you are in need of service.

I was very impressed with Roger, the owner. When A-1 responded to my request on Home Advisor, Roger called me to understand the issue. He asked many questions to understand the problem and was very concerned that I not have someone come out and I incur unnecessary expense if I was communicating the problem incorrectly. After agreeing that I had diagnosed it correctly, he sent two very competent plumbers and they fixed the problem quickly. I couldn't be more satisfied.

Roger was great to work with and very knowledgeable in water softeners. I did not feel pressured or that I was hearing a sales pitch just someone providing knowledge about water softeners. So far so good with the water softener and my wife is super happy saying with the results

I did a lot of research on water softener installers in the local area and finally picked A1 through Home Advisors. I was happy with the no BS and transparent approach from Roger and his team. Roger provided a clear cost breakdown and their work was satisfactory. I would recommend A1 to others.

We are so very pleased with this company. From start to finish they were professional reasonable courteous. I plan to have them back to change filters in my home. I can recommend them completely. Finally a company who listens to customers needs and follows through every step of the way. If I could give 10 stars I would. Just fantastic!!!!! The VassarĂ¢ s.

Excellent communication when planning the job and after the install to make sure we understood how to use our new water softener system. Their team is professional and knowledgable and we would use them again for future projects.

Service person was very professional. Knew what he was doing and did it well. Owner of the company was really helpful in trying to help me get my water softener working to see if it was just a glitch or really needed service. Overall experience was great! I will definitely not only recommend them to friends but will use them in the future.
