The Assignment That Sparked Curiosity
Every year, Oakridge University challenges its senior engineering students with a capstone project designed to test not just their technical skills, but their problem-solving under real-world conditions. mini split refrigerant line
Last spring, the challenge was simple: build a working HVAC model that could efficiently cool a mock living space. It sounded straightforward—until the students realized they’d need to source every component themselves, down to the smallest detail.
That’s when the story took an unexpected turn.
A Team Divided
The group of five friends quickly split into two camps.
One side argued for saving money with generic parts.
The other insisted on investing in premium materials, especially the copper line set, which carried the refrigerant.
At first, it seemed like a trivial argument. After all, it’s just tubing, right? But as one student, Hannah, put it: “You wouldn’t run tap water through a garden hose and expect medical-grade purity. Why should refrigerant be any different?”
Two Models, Two Outcomes
In the spirit of experimentation, the team built two models.
The first used bargain materials, including a cut-rate AC line set they found online.
The second used components from Plumbing Supply And More, with a properly sized, high-quality HVAC line set at its core.
At the demo, both systems started strong. But after 48 hours of continuous testing, the differences became clear:
The budget system leaked pressure, its insulation frayed, and efficiency dropped dramatically.
The Plumbing Supply And More system ran smoothly, stable and quiet, delivering consistent cooling.
The results spoke louder than any lecture.
The Moment of Realization
The team presented their findings to the faculty, highlighting that the invisible parts of a system often determine its success. Their professor, a seasoned engineer, nodded knowingly:
“This is the lesson most contractors learn the hard way. You’ve discovered it in a lab—better here than on the job.”
For the students, it was more than just a grade. It was a real-world insight: quality starts at the core, and in HVAC, that means choosing the right copper line set.
Discovering the Right Supplier
Curious about why their second system worked so well, the team researched their supplier. They found that Plumbing Supply And More had built its reputation by carrying line sets trusted by contractors nationwide. For More Knowledge:
From mini split line sets that install effortlessly in dorms and apartments, to rugged HVAC line sets designed for heavy-duty systems, the company had become a quiet backbone for professionals who wanted fewer callbacks and happier customers.
For the students, it was eye-opening: the supplier matters just as much as the part itself.
Lessons Beyond the Classroom
The project became a case study across the engineering department. Future students now review the Oakridge team’s results before beginning their own builds. The lesson is clear:
A premium AC line set prevents efficiency losses.
A reliable mini split line set ensures long-term performance in compact spaces.
A durable copper line set is the foundation of any system’s lifespan.
It’s not just about parts—it’s about trust in the source.
A Future Shaped by Quality
Several of the Oakridge students have since gone into HVAC careers. Hannah, the one who argued hardest for quality, now works at a design firm that specifies Plumbing Supply And More as its preferred supplier.
“I’ll never forget that project,” she says. “It taught me that the smallest details can make or break a system. And that the right supplier makes all the difference.”
FAQs Students Still Ask
Q1: Why not just buy the cheapest AC line set?
Because low-quality tubing risks leaks, energy loss, and expensive future repairs.
Q2: How are Plumbing Supply And More’s line sets different?
Their HVAC line sets are engineered for performance—seamless copper, reliable insulation, and proper sizing.
Q3: Do mini split systems really need special line sets?
Yes. A mini split line set must be flexible, insulated, and kink-resistant to keep the system efficient.
Q4: What’s the one thing contractors wish they knew sooner?
That starting with a solid copper line set saves years of headaches.
More Than Just a Project
For the Oakridge students, the HVAC capstone project wasn’t just about passing a class. It was about discovering the difference between cutting corners and building for the long run. To learn more:
