I had made an appointment for Thursday, but was pleasantly surprised to receive a call on Wednesday that Eloy could come out a day early. They serviced my RO water system and soft water system. They exhibited excellent attention to detail and worked in a professional manner. When finished they cleared explained what we needed to to do move for the coming year. I will certainly use them again for annual inspections and servicing.

John was very knowledgeable and pleasant to work with. Unfortunately, he didnt have the parts i needed so he will be returning in a couple of days to do the actual work. I will update after the work is completed.

Allegiance Water Services are prompt, thorough, and professional. I found them when they did work on my next door neighbor’s irrigation system. When my irrigation started leaking and watering weeds, I called Allegiance Water Systems for a quote and then to schedule repairs. They send text messages and emails with links to track your technician or to call them direct. Invoicing is quick and easy to access via their billing system. You have everything in writing with links to confirm, deny, or modify your service needs.

David was terrific to work with to get my endless questions answered and align on the right water softener system. Lawson, who installed the water softener was outstanding. He explained service and care issues and did a very professional install. The whole team takes their customers satisfaction seriously. I'll be back for future plumbing needs!

Great company! My water heater and water softener both decided it would be best to stop working on the same day. Allegiance came out and gave me a quote for both and their price was great. I feel like they were really interested in helping me.

I love this business. They go the extra mile to make sure their clientele are taken care of. My hot water heater went out on New Years eve and required a part to fix it. The part was unavailable and Rheem the manufacturer was closed until Monday. John Gonzales from Allegient brought out a new unit and installed it, so that I would have hot water for the weekend. This is a great company, and I am glad that I selected them. UPDATE Allegiance is my go to water company. My house is 50 years old now, so I'm glad I have them to call if I have a problem. Rommel Valenzuela came today to service my filtration system. He was nice, professional and did a great job.

Allegiance’s technician Eloy Garcia arrived promptly, explained and showed me the issue with my water softener and also he noted some water in tray beneath the water heater that I had even noticed. He fixed the motor on softener and then removed and replaced my water heater as he noted it was still under manufacturer’s warranty! I am so please with his prompt, thorough and efficient service. I highly recommend him and Allegiance Eater Services!

Had an issue with my sprinkler system, something failed and I had a big wet spot on the side of my house. Called in and was helped with instructions on how to turn off the sprinkler side so no water would go to it until a repair could be scheduled. Paul comes out and shows me the problem, we set a time and he fixes all of that, THEN while testing, just waltzes into the spraying sprinklers and dials in where the water SHOULD have been spraying, like " oh, that's the wrong direction to spray for this area..." Then he programs the whole thing to fix my already mediocre lawn and bushes, told me what to do to improve my lawn through yard care and got into his car with soaking pants and thanked ME! 10/10.

John was on time and professional. He fixed the leak in my backyard system and tested it to make sure no further leaks. He also checked the front yard and found an additional leak that I hadn’t noticed and also fixed it in the same trip. Super happy with the great service and will definitely call these guys again for future plumbing repairs outdoors and indoor.
