From the first call, Ed the owner worked around my availability and made the entire process super easy and fast. The installation technician was knowledgeable and efficient, and Ed walked me through the owner's instructions carefully. With that said, I think what really sets Ed's company apart is his obvious pride and care for his business and customers, as clearly evidenced by his prompt and excellent after-service. I felt a bit bad about asking him all sorts of questions years after the job was done but he always responded quickly, enthusiastically, and professionally. I had a few top rated service providers come by for quotes but I'm sure that I made the best decision to go with Ed.

Very disappointed with the communication and overall service from this company. I was told one…read morething, while my tenant was given different information, which created unnecessary confusion. After the technician completed the filter service, my water filtration system was not working properly. I contacted the owner expecting them to stand behind their work and help troubleshoot the issue. Instead, without performing an official inspection of the system, I was quickly told that the resin likely needed to be replaced and was quoted approximately $500 for another service visit. My system is only about 5-6 years old, so I was concerned that such an expensive repair was being recommended without properly diagnosing the problem first. We later discovered on our own that the actual issue was that the filtration system settings had not been set correctly after the technicians changed the filters. Once the settings were corrected, the system worked. My biggest concern is the lack of communication and proper troubleshooting. Before recommending a customer spend another $500, especially immediately after your technicians serviced the system, I would expect the company to first verify that the work was completed correctly and that the system settings were properly configured. Unfortunately, based on my experience, I would not recommend this company.

In this economy, it's important to research a bit to find service providers that are reasonably priced without compromising quality. I called for an initial quote and Trung took some basic questions and advised us the next step would be for him stop by the house for a quote. We agreed on a date and time, and he showed up promptly. After a quick assessment, including understanding the neighborhood and its hard water challenges -- he was able to give us an instant quote. Of course, we had to discuss the quote with the family to see if it was something we were able to work with. Within a week, we were able to get in touch with him to schedule the installation appointment. Trung arrived the day of our appointment and got straight to work. He installed the water softener tank along with corresponding piping, and secured everything with a drill. He finished in record time (less than two hours) and was very thorough with explaining maintenance instructions, etc. The product is covered with manufacturer warranty and he wrapped up the appointment by advising us to call him should we ever experience any issues. The unit looks great in its setup, our water is cleaner and softer, and we didn't have to break the bank. Win-win all around. Exceptional experience for service, quality, and affordability!

As a new homeowner I did not have much of an experience with water in general and plumbing/piping in general. On the initial phone conversation Rick Randazzo asked me some questions about my house and piping and gave me some thorough recommendations about how to prepare for the process to get started. I needed to do some repiping and also chose my repiping company to be my own installer for the water softener product. Because of my lack of experience, Mr Randazzo was kind enough to talk to my installers about his requirements of correct installation. When the installation was complete and it was time for turning on the system, Mr Randazzo came and found that it was not done correctly (the repiping guys drained the brine pipe o.O). Long story short Mr Randazzo came two more times to my house on pretty short notices to finally approve my installer's job. He never complained but gave precise directions on how to do it correctly. It was all my installer's fault as they kept sending different people each claiming they know exactly how to do the job. I can't thank Mr Randazzo enough for his kindness and support. And of course, for the very soft water my family is enjoying every single day. I am sure my appliances are pleasantly surprised as well. This was the best change we did in our house for the last 3 years and I am really happy I went with Randazzo's.
