"Overall a very good company and I would recommend them. We had an AIO system installed to remove hard water and iron (among other things) along with a water softener system. My one complaint would be this. The water filter they installed had a leak. They came and looked at it and just fiddled with it if you will until it stopped. This was covered under their warranty. Six months later when I changed the water filter, the same leak started again and I needed a service call. This time they had to replace the part, not covered under warranty. The service call and parts and labor were not covered under warranty because it was six months after being installed. I would not have known this though until I went to change it for the first time and had an ongoing service call for the same reason with them. I was not impressed with that level of service."

"Dave is AWESOME! Talked with me and we went though all the work he was doing. We checked the electric Panel and ensured a good power source. I feel confident in his work, his personal integrity and the quality of the parts he repaired/replaced my Water Heater with."

"Simons is the best company we have ever done business with in the North Country. We chose them to install five mini splits for both heating and air conditioning after getting five other quotes. We could not be happier with our decision. From getting the initial quote from John, to Honey and Missy in the office answering all our calls and questions, to Ryan and his partner installing the system on time and as promised — we have never used contractors this professional either in the North Country or in New Jersey! After it was installed and we went back to NJ, and we realized the Wi-Fi was not working. John went to our house first thing the next day, and worked with my husband over the phone to set up the app so we could monitor the temperature from NJ. Three months later, we arrived at our home in NY and it is the first time in 26 years that we were able to raise the temperature the day before we left NJ, and arrived to a warm and comfortable home on Lake George! Thank you everyone at Simons we look forward to working with you going forward."

FAQs for water treatment & purification system repair or service projects in Nassau, NY

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
