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.

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.”

Modern Solutions for Multi-Zone Commercial HVAC Systems

Variable Refrigerant Volume (VRV) and Variable Refrigerant Flow (VRF) systems provide flexible, energy-efficient heating and cooling for buildings that require precise climate control across multiple zones. Over time, aging components, outdated controls, or increased demand can reduce system performance.

At Shafer Mechanical, we provide professional VRV/VRF system replacement and retrofit services designed to restore efficiency, improve reliability, and support the long-term performance of your facility.

Advanced Control Integration

Modern VRV/VRF systems offer powerful control capabilities that improve building comfort and energy management. When replacing aging equipment, our team integrates updated control technology that allows facility managers to monitor and adjust temperatures across multiple zones with greater accuracy.

With upgraded control systems, businesses can:

  • Maintain consistent comfort across different areas of a building
  • Monitor system performance and energy usage
  • Adjust temperatures quickly to meet operational needs

VRV/VRF Equipment Replacement

As equipment ages, compressors, indoor units, and control components may struggle to keep up with building demand. Replacing outdated VRV/VRF components helps restore system performance while improving efficiency and reducing maintenance issues.

Our replacement services can include:

  • Upgrading outdoor condensers and indoor units
  • Replacing aging refrigerant lines and components
  • Improving system efficiency with newer equipment models

Improve Efficiency and Reduce Operational Disruptions

For facility managers and building owners, HVAC reliability directly impacts operations. A properly designed and installed VRV/VRF replacement system helps maintain consistent temperatures, reduce energy consumption, and support uninterrupted business operations.

Shafer Mechanical works closely with property managers, facility teams, and building owners to ensure system replacements are planned carefully and installed efficiently with minimal disruption to daily operations.

With decades of commercial mechanical experience, our team delivers solutions that support long-term performance and reliability for your facility.

Keep Your Building Running with Reliable VRV/VRF Performance

When your VRV or VRF system begins to show signs of aging, replacing it at the right time can prevent costly breakdowns and restore efficiency across your facility. Shafer Mechanical provides expert system replacement and retrofit solutions designed to support consistent comfort, improved energy performance, and dependable operation. Contact our team today to schedule an evaluation and learn how we can help upgrade your building’s VRV or VRF system with minimal disruption to your operations.
