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!

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.

I have used Allegiance Water since 2018. The company and service is outstanding. John Gonzales was our repair person for this call. He changed our RO water filters, installed a leak detector for the RO, and repaired our water shut off valve. He was GREAT!!! He is very knowledgeable and dependable. I highly recommend Allegiance and their team. Thanks

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.

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.

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!

Why should you hire Allegiance? Quality. Dependability. Customer service. Experience. Dedication. Hard work. This company takes quality experience and service to the next level. I haven’t worked with many home service companies who do such a good job like this. From the moment we got the quote, until the minute the job was done, they were reliable and they provided the service we requested. First they came out to inspect the issue. Once they figured out what was wrong, they provided a verbal quote and followed up with a digital quote. I was able to accept the quote digitally and put a deposit down to begin the work. Since our system needed to be replaced, it was quite a process and luckily they had it all under control. They contacted the city and cox communications to flag their underground items so that they knew where to avoid. Then Lawson came out and literally spent an entire day replacing the system. The customer service was above and beyond. Yes there are a million plumbers and irrigation companies out there, but there aren’t as many reputable, trustworthy, licensed and qualified ones like Allegience.
