It Started with a Cold Storage Project
Last spring, I was handed the budget for a new 10,000 sq ft cold storage facility. As a procurement manager at a mid-sized refrigeration installation company, I’ve seen too many projects go red because someone chased the lowest unit price. I manage about $500,000 in equipment spend annually, and I’ve kept every invoice for the past 8 years. So when it came to picking evaporators, I knew I needed to be smart—or at least not repeat the mistakes I’d watched others make.
My shortlist came down to three brands: bohn, KeepRite, and Heatcraft. The project specs called for bohn evaporators because the client had good experience with their reliability. But the purchasing team wanted me to compare anyway. Fair enough.
The Temptation of a Lower Quote
Vendor A quoted $18,200 for the evaporators and a matching bohn air cooled condenser. Vendor B came in at $15,900 for a similar capacity from another brand. On paper, B looked like a no-brainer—until I started digging.
The cheaper quote didn’t include the controller harness kit (an extra $700) and their “standard lead time” would push us past the project deadline. I said “as soon as possible” to my contact; they heard “whenever convenient.” That miscommunication cost us two weeks (ugh).
In my experience—and I’ve tracked this across about 60 orders—the initial price is only half the story. The real cost shows up in installation complexity, maintenance frequency, and warranty support. B’s condensing unit had a different refrigerant type that would have required a separate recovery machine. That alone added $1,200.
“I saved $2,300 on the unit price, but after factoring in the harness, the lead-time rush fee ($800), and the refrigerant compatibility, the net loss was actually $1,900. The cheap choice would have been more expensive.”
The Garage Heater Detour
While the cold storage equipment was being finalized, the maintenance manager asked me to also source a garage heater for the vehicle bay. Totally unrelated to bohn, but it was another chance to apply my TCO thinking. I looked at three models, compared gas line hookup costs, thermostatic controls, and efficiency ratings. We ended up with a well-rated unit that wasn’t the cheapest—but its lifetime operating cost was 15% lower than the bargain option. The same principle applied.
A Surprising Filter Lesson
One of the technicians suggested upgrading the condenser’s air filters to improve airflow. He recommended K&N air filter products, which he used on his own truck. I even checked a Can Am air filter as an alternative—but after reading bohn’s installation manual (again), I realized the OEM filters were designed specifically for the fan curve. Using aftermarket filters could void the warranty. We stuck with bohn’s recommended filters. The tech was disappointed, but I’d rather be safe than face a $4,000 compressor replacement later. (That’s not a hypothetical—I’ve seen it happen on another project.)
The Final Choice and the Real Lesson
After a month of back‑and‑forth—I must have gone through six versions of the cost spreadsheet—I chose bohn. The bohn evaporators and bohn air cooled condenser cost more upfront, but the total cost of ownership over five years was lower by about 11% when I included energy consumption, filter replacement frequency, and local service support.
The bigger lesson, though, was about transparency. I spent two hours walking the installation team through bohn’s model naming convention (the “nomenclature” as they call it) and the sizing chart. At first they rolled their eyes—but after the first unit arrived and everything fit perfectly, they thanked me. An informed team makes better decisions and fewer installation errors.
If you’re ever torn between two bids, do yourself a favor: calculate the total cost, not just the price tag. And don’t be afraid to educate your team on the details. It saves money in the long run—trust me, I’ve got the spreadsheets to prove it.
