I had Eloy come by to repair a water softener system that had failed, as well as replace the filter in the RO system. He was courteous, knowledgeable, responsive, timely, and really knew his stuff.

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

Assessed my sprinkler system. Told me and showed me the main issue I'm having. No charge! Very nice and knew the answers to my questions. Didn't try to sell me anything. Will have these guys over everyone else I've done business with.

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.

I had an exceptional experience with Allegiance today. My old gas water heater needs to be replaced. I called Allegiance yesterday and discussed with David who is very knowledgeable, transparent and told me pros and cons among the different water heaters. I decided to go with 50 gallon Bradford White water heater. Ruben came in next day and clearly explained to me what is the process. He is excellent, very skillful and told me how to maintain it. He cleaned everything afterwards. I am very happy with their services and will call Allegiance for my plumbing issues for sure. Ruben from Allegiance Water Services did an excellent job again today. I had water hammer issue for a couple of months and my pipes coming out the main pipe weren't connected right by a previous plumber. The irrigation system controller needs to be replaced as well And it is now upgraded to an enabling phone control unit. Ruben did an excellent job on replacing the unit and repiping everything. It only took him an hour and they work great! Ruben is very experienced, knowledgeable and efficient. It wouldn't go wrong for Ruben to do your plumbing jobs.

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!

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.
