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.”

The Witte Museum

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.”

Rooftop Package Equipment Retrofit

Rooftop package units are a common solution for commercial and industrial buildings due to their efficiency and ease of maintenance. Over time, however, these systems can become less efficient. Our rooftop package equipment retrofit services provide the following benefits:

DX Split Systems Retrofit

DX split systems offer flexibility for heating and cooling specific areas of a building. Our retrofit services for DX split systems focus on:
  • Component Upgrades: Replacing older components with high-efficiency models, including compressors, condensing units, and evaporators, to enhance overall system efficiency.
  • System Expansion: When additional heating or cooling is needed, we can expand existing DX split systems to cover new areas, ensuring consistent comfort throughout the building.
