Testimonials

  • Office staff is wonderful to work with and they respond to questions quickly. I recently had some issues with my home pool equipment and a tech named JC came out and was extremely helpful and I think he went beyond what he had to do in order to fix the issues at hand. Very professorial and friendly. This type of service calls makes the money we spend yearly worth it. THANK YOU.

  • Good morning! I just wanted to take a minute to thank you for your assistance with our pool predicament. We have had countless bad experience with pool cleaning services and decided to take matters into our own hands. Yesterday, Tony Marruffo came out and did a Pool School session and finally, I feel like I know what I’m doing. He was patient and answered every question I threw at him with patience and spoke in a language could understand. He also made sure I was ok with what I’d learned before he left for the day. Thank you so much for employing such kind, caring, efficient staff and I hope to work with H3O Water Systems in the future.
    God Bless You,

  • We have been working with several different contractors for the past 3 months on various projects and it was your company that finally gave us faith in the contract world. We have had lots of issues and poor quality of work until you.
    We were so impressed with the prepping team that came to our home last Friday and Saturday. They were polite, very efficient, and worked well as a team with Carlos as the head of the team. We told them time and again how impressed we were but I wanted the “boss” to know and pass on proper recognition to his employees. They did excellent work, left the area clean when they departed each day and were just a class act team. We watched in awe as to how things should be done.
    We also were very impressed with Brandon. He also was very polite, efficient and followed thru with us at all times. Another class act.
    Please feel free to use us as very satisfied customers for any references. And please, make sure your team receives the highest of compliments. They serve your company well!!

  • This is the time of year that we check our sprinkler system for any leaks or repairs that may need to be done. We contacted H3O and within 24-48 hours they were here to repair our problem. They are the most pleasant and professional individuals that we have had the pleasure of dealing with in this town which is rare to find and we would recommend them to anyone!! We have used this company for years and will continue to do so!! Kudos for hiring such a great crew of people!!!

  • I have used 4 irrigation companies over 18 years, H30 being the last and the only one I will use in the future. Several years ago my sprinkler head type and arrangement was made more efficient by H30 for a very reasonable price. Recently my 18 year old system controller box needed to be replaced-no digital readout at all- and a modern one was installed for a reasonable price. And to top it off every sprinkler head was look at and any that were not performing or were over spraying were adjusted. I feel that I now have a new system thanks to H30.

  • Thanks guys for retrofitting our backyard irrigation system to drip. Given the on-going drought restrictions in San Antonio, this is the only way to go. Your team was thoroughly professional and finished the job quickly. I appreciate the timely repairs on the small leak. The system is working beautifully now and our plants are thriving. Next year we’ll do the front yard.

  • Hey Tony,
    Thanks for sending the guys out here to tweak our sprinkler system last Thursday. It’s to our benefit that you’re such a perfectionist! I am loving the sprinkler system – it makes my life so much easier.

  • A week ago we called and confirmed you did leak repair. We explored the various options.
    Pool cleaning company – replaced spider gasket.
    Leaks continued – we contacted a leak detection company (as per your recommendation) they wanted $450.00 to find it.
    At that point it became obvious that the leak was up high as the pool settled just above the bottom of the skimmer.
    We spoke to Mike again and decided it was time for the dye test.
    Today, Mike your technician came over to do a dye test
    In less than 45 minutes he found the leak and fixed it.
    Best $85.00 dollars we ever spent
