Check Out Our Customer Reviews
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.
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
Allegiance has been great. Eloy was perfect. I recommend this company highly and will certainly continue to use them in the future.
Friendly and reliable. Does great work!
Fast and reasonable.
Will make sure the job gets done!
Extremely impressed and satisfied with professionalism and service. A real person always available by phone unlike several competitors I tried to reach. Eloy the tech was the best in all respects.
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.
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.
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 was in a panic when my sprinklers started making loud noises at 5:30am. I called Allegiance water and was able to get a service rep out the next day. They...
The service tech was pleasant, courteous and knowledgeable. He tracked down the problem and eliminated it as quickly as possible, as he was aware that what his time cost us in getting the job done.
Josh and the office and service tech Rommel were excellent in every way! Professional, knowledgable service of issues with my water softener.
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
Excellent job! Will use them again.
Johnny Gonzales was very professional, courteous, and thorough.
Lawson installed a reverse osmosis system at our new home today. While he was here, he also helped answer (many!) other questions and helped inspect the home’s irrigation system for me. He was thorough, professional, friendly, and patient. Thanks so much Lawson and Allegiance!
They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
Annual service on RO water system. Rommel was friendly, fast and professional.
We had a leak in our drip system. Johnny was awesome. He took the time and explained what the problem was and how to get it fixed. He didn't have the part...
Very smooth transaction! One phone call got the osmosis and softner system scheduled and an experienced technician came and installed both within 2 hours! Great experience. Thank you!
I am so grateful to Lawson for helping me with my spinkler system. He is knowledgeable, kind, and patiently answers all my questions. I trust him and Allegiance Water Service for all of my home’s plumbing needs.
Friendly, knowledgeable and efficient.
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.
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
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!
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 sent a repair man to fix a broken sprinkler head.. He was courteous, pleasant and well informed. He fixed the head and checked to be sure the whole system was working again correctly. I appreciated his service. Thank you
John was great. Professional and courteous. Very pleased with his work.
Excellent service and water quality!!
Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.
I’ve used this company for multiple services! And they are great at everything they do. They are super responsive to all of my needs and are always on time. I will never use any other company!
Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.
Arrived on time , perfectly described a job he'd be doing and provided excellent service , would recommend him to all of my neighbors, did a great job fixing my water heater leak
Had a hot water heater replaced today; Lawson did a fantastic job. The workmanship is very professional. Lawson was on time and did exactly what he said he was going to do.
