Air Purification

Air is essential to our daily lives. While there are systems in place to clean the air in our homes to be free of germs and toxic chemicals, there are still impurities which can affect our overall health and happiness.

Improving Your Air Quality

Air purifiers are the best way to clean the air in your home! With an air treatment system in your home, you can capture airborne particles in the moving air like allergy-provoking dust, pet dander, pollen, smoke and mold spores.

The Beyond Guardian Air purifier is unlike any others. It got its origins in the Nasa space program. The technology was dramatically enhanced and transformed it to illuminate airborne contaminants everywhere. It also cleans surfaces and clothes!

If you have breathing issues, allergies, asthma, challenged immune systems or pets in the house then reach out to Fidelis Plumbing today!

Matt and Carter work excellent together, they have installed my system outside and inside. I had my RO system running through my refrigerator at first. I recently changed it to a running faucet because of lower pressure coming from my refrigerator. They are quick and informative about all the steps they took to install my RO faucet. They are both very professional and I welcome them both anytime to install, repair or maintenance my home plumbing. Thank you Matt and Carter for your excellent work/install.

I have had the water filtration system for about a month now. Installation took two visits due to unforeseen circumstances. The company gave me extra soaps to make up for it to last me 10 years. A minor glitch as well installing the system which caused water to go everywhere. The installers apologized and cleaned up the mess. The water is soft and tastes great. It is very pricey which is the one downside of the system. Katy came to present the product and did a fabulous job. You can tell she loves her job and helping people have clean water in their homes. She communicated well with me when issues came up. Overall happy to have the system installed.

My experience with Fidelis Plumbing has been great! We just purchased the water softener system and air purifier system and are very happy with both. Katy is our point of contact and she has truly been amazing! She came to our home and showed us our current water quality, and what it would be with the purification system. It is clear that she cares about her customers and wants to do right by them. She has provided excellent customer service for us and has been involved in every step of the installation process to ensure that everything goes smoothly! We will definitely be recommending her services to our friends and family.

My skin feels like butter in the shower now! The service was great! Jeff was our representative. He was very knowledgeable of the system and enthusiastic. The installation team was very professional and informative. They did not leave until the job was done. Along with the water softener you get 5 years with of free soap!!!

Erica Marrow

I just had a water softener installed in San Antonio by Justin L. & Matt M. They were professional, thorough, knowledgeable, and made the installation process very smooth for me. After installation, they explained how the water softener worked and how to maintain it. I’d highly recommend.

Stephanie Garcia

Isaac Garcia & Justin Leyrer we’re both very professional, courteous, communicative, and friendly, not only with me, but with my dog and 16 month old son. Was happy to have them in my home and hope to have them for my next service call!

Ashley Monplaisir

I would definitely recommend Fidelis for plumbing needs. David Gonzalez and Jacob Sanchez were the technicians called to my order. They were very courteous and informative. I was more properly educated on my system, and learned some self-help methods to avoid future issues.

Thanks for the great service!

Michael Snell

My Fidelis rep Terrell provided a great explanation of products and all of the benefits that are provided with the systems. Very professional and courteous reps with not only sales, but also those who came to do the installation. I would definitely recommend and pleased doing business with them!

Kayla Squyres

Had my system installed back in 2016 under a different company name whom I lost contact with. My RO system lost pressure and after some digging online I found out they had changed their name to Fidelis. Called them up to see they still had me on file and scheduled a tech to come out. David Gonzalez and Jonathan Wycoff showed up to quickly find and fix the problem. Both were very polite and informative on what may have caused my problem. Before leaving they tested the water, checked out the softener system, and reconnected the RO line to the fridge for me. David even went a step further and gave me a much needed refresher on maintaining the softener system and it’s electronics yearly, how to restore it in the event of a power outage, and how to bypass the softner should I ever need to. Thank you to David and Jonathan for coming out and getting me back up and running.

Responded to a post card saying Fidelis had a package on hold. Knowing full well that it was a “sales pitch”. Turned out the “package” was a $25.00 gift card and to claim the gift card all we had to do is let a salesman come out and test our water and air quality. As we had just moved to the area and had a pretty good idea our water and air was not of the best quality this was just fine with us. Did not expect the “salesman” that came out. First and foremost he was not a “salesman”. He (Michael Fox, Water Technician) was a pleasure to “visit” with. He was very professional in his presentation and appearance. His presentation was enlightening and thorough. He was not pushy even when we explained that we weren’t ready to make a commitment to buy. He made a very good offer and very graciously accepted our decision not to buy his product.

I’ve had wonderful service with Fidelis Plumbing. Installation was quick. Customer service is excellent. Quick to respond to questions and service calls. I’m loving my new system. They also send out helpful hints to keep your pipes safe.

Stacie Brown

I will start by saying that I don’t really like their practice on getting customers, since it feels like a scam. That being said, everyone we worked with was an absolute pleasure. The guys that came out for the Install were super friendly, and were her not just to “do an Install” but also to make sure I was completely happy with the install and where the Softener was located. I would recommend them to anyone in the Hutto Area for a water softener!
