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.
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.
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!
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.
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
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.
Fast and reasonable.
Annual service on RO water system. Rommel was friendly, fast and professional.
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...
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.
Allegiance and Eloy are my "go to" plumbers. Prompt, efficient, cost effective and courteous.
Excellent service and water quality!!
Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.
Allegiance has been great. Eloy was perfect. I recommend this company highly and will certainly continue to use them in the future.
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 installed a water softener system and did a great job. He also updated our r/o system. Very professional
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!
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!
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.
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
Lawson was punctual, polite, clean and knowledgeable. He serviced the RO system. Recommended an alarm to detect a leak. Will think about it.
Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.
Fixed my backyard sprinklers without having to put a whole new system in.
We have used Allegiance Water Services for several years now, and we have not been disappointed. Very professional, quality work, friendly, reliable.
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.
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.
Friendly, knowledgeable and efficient.
Friendly and reliable. Does great work!
Highly recommend for Navien install and servicing.
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.
Josh and the office and service tech Rommel were excellent in every way! Professional, knowledgable service of issues with my water softener.
