Annual service on RO water system. Rommel was friendly, fast and professional.
Fixed my backyard sprinklers without having to put a whole new system in.
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.
Allegiance is fantastic. Lawson in particular is a total professional. Super knowledgeable, trustworthy, and efficient. Diagnosed our crazy irrigation issues and came up with a cost effective solution.
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!
Technician was here within 30 minutes. Did a great job for a fair price. I highly recommend Allegiance…..
Looking into my options as soon as I hear back about my options
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!
John was great. Professional and courteous. Very pleased with his work.
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!
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...
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.
Installed water softener
He was wonderfully informative and polite. Educating me on my irrigation system, as I'm from Michigan and very unfamiliar with them.
Josh and the office and service tech Rommel were excellent in every way! Professional, knowledgable service of issues with my water softener.
These guys replaced my Water Heater today. Prompt, fair price, easy to work with. 5 Stars is not sufficient to rate their quality
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.
He installed a water softener system and did a great job. He also updated our r/o system. Very professional
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.
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.
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.
Would highly recommend. Lawson was very professional.
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
Fast, reliable. Polite repair people. Fair price.
Lawson was incredibly friendly, informative and professional. David was also a standout for his strong communication and customer service. 10/10 would recommend to friends and family.
Fast and reasonable.
Eloy is just awesome, friendly, detailed, professional and took time to walk me through all work completed, highly recommend.
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.
Johnny Gonzales was very professional, courteous, and thorough.
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.
Technician patiently walked me through my current setup, identified multiple leaks, and looked to save money by combining and eliminating unneccesay zones.
Allegiance Water Services was great! They prioritized my urgent request and Lawson was great when he came to diagnose the issue. He thoroughly explained the problem and gave me different options and advice on future work. 5 star support!
Will make sure the job gets done!
Excellent service. Rommel was very professional. I will call on them again. Marc C.
