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!

Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.

Paul came today to check my Rain Bird system controller. I have worked with him during my new irrigation installation project at the beginning of this year. I was extremely pleased with the outcome then and again today. I specifically requested him for today’s job. As always, he offered excellent, professional service, knowledgeable, courteous and friendly. I would refer him and Allegiance Water Service to my friends with high remarks.

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.

What a great job by everyone involved in this process!! A new drip system was installed in both the front and back yards - first time a system was installed by real professionals. System works great and is easy to use!! Highly recommend Allegiance!!!

I have used Allegiance for years now and every time I'm still amazed at how courteous and professional they are. Every year I have my R.O. filter changed and my soft water big blue filter changed. They also perform my mist services for the backyard with shutdown for the winter and startup in the spring. 100% recommend them!

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.

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.

After 5 years we had water softener , we found out we use soft water for our pool and watering the plants in our back yard , so I called this company they responded fast and the next day they sent their technician Ruben . After we agreed on his estimate , he came the next day. He did awesome job on separating our soft water. Ruben was knowledgeable, fast and reliable. I am so happy with his work and recommend him and this company to everyone.
