Kristin Buchhorn
The RK Group
“For the last few months, the team at Shafer Mechanical has been invaluable to operations here and my own workload. This account is certainly a demanding one for several reasons. We have a lot to maintain, including the large office warehouse building and a historic mansion as well as a new office building and mobile asset units. We have unique systems to maintain, namely because of the design and specs of our components. We have difficult systems to maintain, partially because of the design and mostly because we run the system in overdrive regularly. We also, like other accounts, hope to be the first to gain attention from the service schedule when an issue arises. Thank you and your team for the partnership. I look forward to working together.”

Swan’s Landing Assisted Living
“We have been using Shafer HVAC since first construction. Our Assisted Living facility had a leak today from the attic. We called and the technicians showed up within an hour. They diagnosed, explained the problem, and fixed the problem in no time. The technicians are Chuck and Nick- thank you both for their kind hearts.”

“We’re so grateful for this ‘in kind’ donation from Shafer Mechanical! Having well-maintained and high-quality HVAC systems on campus is a critical component of keeping our clients, staff, volunteers, and dogs safe and comfortable. This partnership also allows us to put more resources directly into preparing future generations of guide dogs for Texans who are blind. Thanks to Shafer Serves, more people will be able to benefit from these amazing guide dogs.”

Oblate School of Theology
“In the last 6 months we have been working very close with Shafer Mechanical. There have been a couple of guys who have come out who were extremely helpful and knowledgeable. I have worked closely with all them, but Chuck has gone above and beyond. On Saturday March 30th (holiday weekend), we had a large wedding at our center and the AC was not working properly. I called him directly and he walked me through a couple of things but still could not get it going. So, he came in, figured out the problem, and got the AC to work; and we were able to hold a successful wedding here at our center. That is just one of the stories and great things that Shafer has done for us.”

Protect Your Plumbing Systems and Equipment

Water quality can have a direct impact on the performance and lifespan of your facility’s plumbing systems and equipment. Hard water, mineral buildup, and contaminants can lead to scale inside pipes, inefficient equipment operation, and costly repairs over time.

At Shafer Mechanical, we provide commercial water softener and water treatment repairs and installations that help businesses maintain reliable plumbing systems and protect critical equipment. Our team evaluates your facility’s water quality and recommends solutions that support long-term system performance and operational efficiency.

For restaurants, healthcare facilities, manufacturing operations, and multi-tenant buildings, proper water treatment helps prevent buildup that can impact fixtures, appliances, and mechanical systems.

Shafer Mechanical has served Central and South Texas businesses for generations with reliable mechanical and plumbing expertise, delivering solutions that keep facilities running smoothly.

Commercial Water Treatment System Installation

Installing the right water treatment system helps reduce mineral buildup and maintain consistent water quality across your facility.

Our commercial installation services include:

  • Water softener system installation
  • Commercial filtration systems
  • Scale prevention solutions
  • Water treatment system upgrades and replacements
  • System sizing based on facility demand

Properly designed systems help protect plumbing infrastructure while supporting the performance of equipment such as water heaters, dishwashers, and cooling systems.

Water Softener & Treatment Repairs

Over time, water treatment systems can lose efficiency due to mechanical issues, mineral buildup, or aging components. Our technicians diagnose problems quickly and restore system performance so your facility can continue operating without disruption.

Common repairs include:

  • Resin tank issues
  • Valve and control failures
  • Salt bridging and system blockages
  • Reduced softening performance
  • System leaks or pressure problems

Fast, reliable service helps minimize operational disruptions and protects the plumbing systems your business relies on every day.

Why Water Treatment Matters for Commercial Facilities

Water quality affects more than just plumbing. It impacts equipment performance, maintenance costs, and overall facility operations.

A properly maintained water treatment system can help:

  • Reduce scale buildup in pipes and fixtures
  • Extend the life of water heaters and appliances
  • Improve system efficiency
  • Protect plumbing infrastructure
  • Support consistent water quality throughout your facility

For facilities managers and business owners responsible for multiple locations or high-use systems, proactive water treatment can prevent avoidable repairs and downtime.
