Check Out Our Customer Reviews
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.
Very prompt service and were there at scheduled times. Both tecs that have been here, Dan and John, were outstanding. Very professional staff including Josh. Pricing is reasonable. I would highly recommend this company.
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.
They answered the phone (after several other business didnt) and came right out to do the estimate and complete the work. Quality is good. Will call next time I need sprinkler/landscaping work.
They have done several projects for us and they were done efficiently and well. I highly recommend them for any water service
John was great. Professional and courteous. Very pleased with his work.
Installed water softener
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!
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
Friendly and reliable. Does great work!
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.
Ruben and Juan were the best! Great attention to details, all zones were color coded, and helped us with the use of the Rain Bird app. We couldn’t be happier with the great work!
Paul is all of the above plus irrigation systems technologically advanced.
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.
Lawson with Allegiance Water has done work for us the last few times and he’s very polite and professional and has done great work for us!
Technician was here within 30 minutes. Did a great job for a fair price. I highly recommend Allegiance…..
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.
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!
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!
Lawson Key was very professional, respectful and kind. He did a great and solid job of installing a new faucet for our water filtration system!
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!
Friendly, knowledgeable and efficient.
Great company. We would highly recommend them. Courteous, professional, fast response time. Very reasonable rates. This is the third time we have used their services and have been very happy every time.
Excellent service. Rommel was very professional. I will call on them again. Marc C.
Very professional and responsive. No guess work as to when they arrive. Explained everything and cleaned up yard after they were done. Recommend...
Would highly recommend. Lawson was very professional.
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 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.
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.
These Guys are awesome! They were on time and on the mark. Service was professional and they did a clean repair. I would definitely recommend them.
Excellent service
Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.
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.
