    The owner is untrustworthy. Never put deposit. Your money could be gone for any reason (store transfer or just "policy change"). I purchased the deposit card but didn't use it inside for water due to obvious reason during last year. Then when I tried to use the deposit card the owner said it expired after one year. He didn't tell me about this policy when I paid and there is no such a policy on the card. Even I would like to pay the possible price difference, he still insisted that the card expired and even stepped up to me almost face to face to threat me to leave his store. Oh, forget to say, I purchased 5 gallon water buckets from him and one bursted out in the car during driving without hitting anywhere. Check them you will find the bucket is so thin.

    This store is selling hand sanitizer at a gauging price that has no alcohol content despite's the label says 70% alcohol. If you bought any of such hand sanitizer from this store that looks like the one I bought there, stop using it because it does not work and you may be catching the virus despite you think your hands are clean by using it! I am really mad about such unethical practices at this pandemic time. Gauging price is still acceptable if the product itself works. I would really think twice to ever purchase any product from this store after this experience,,, Strobgly advice to avoid this store! How do you know there is no alcohol in it one may ask... If it has alcohol, as soon as it gets applied to you hands, you will feel the coolness as the alcohol evaporates from your hands. This product did not have that feeling at all... that made me really suspicious so I did another experiment with it. I squezed it on to a cup and light a match over it and it did not catch fire... I used another hand sanitizer that I bought over CVS that only has 65% ethyl alcohol and it catch fire right away and burnt for a while. This is how I concluded there is no alcohol in this product!

    Very unfriendly bordering rude. I went there once and found it cramped also. I found another store in the area and am happy now.

    De Anza Water Conditioning installed a water softening system and reverse osmosis (RO) filter…read moresystem in Spring 2026. The installation includes a 1-year service warranty, which has proven very helpful. Side note, if you add a mineral cartridge to your RO system and that RO system supplies an existing copper water/ice line to a refrigerator, be sure to have the ice line replaced with polyethylene tubing. If not, the minerals will degrade the copper ice line, resulting in leaks. Many thanks to José for the super job he did capping our old copper ice line and replacing it with under cabinet-mounted polyethylene tubing--works great, can't see the tubing, no leaks! Many thanks to Niko for resolving a problem we had with melted potassium in the reservoir tank for our softening system. Niko was very patient as he explained the problem and showed me step-by-step how to fix the issue myself if it happens again. He also tested the water until the results confirmed that the problem was resolved. Many thanks to Angel for taking service calls cheerfully and with kindness and efficiency. I really appreciate the great service my family has received from De Anza Water Conditioning. I would hire them again without reservation.

Our Kinetico system was effecting a major water leak (600 gal over ~28 hours), and I tried reaching them at different numbers after hours; a representative contacted me from each of those lines and set up an appointment the following day, 8a-12p window. Our technician Sonny Vigil arrived at 9AM, very professional and respectful. He explained his triage per step, replaced parts and fixed everything up without hassle. Shared tips about the filtration system and general troubleshooting. He additionally performed a full system checkup and replaced our filters as part of the same service visit; we would've otherwise run out of potable water shortly. Serviced everything efficiently and effectively. I had originally planned to get to work in the afternoon, but everything was resolved and ready to go by 10:30AM.

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.

Ed was very polite and educated me further and helped me understand the difference between the different types of filtration and softening products on the market. Ultimately I decided to go with Soft Patagonian not just because they had a superior product but also they had a very respectful and professional team. That made a complicated install for others extremely clean and easy. I highly recommend them and have already shared with all of my neighbors who I think they should consider if they are looking at a water softener for their home. By the way this is the best purchase I've made all year!

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!

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.
