I can trace the trajectory of my career all the way back to a job walk in Pasadena.
Back in 2007, our sales manager suggested we take a look at an installation of a new type of heat pump. It was one of the first installations of its kind. It had the ability to connect multiple fan coils to a single outdoor condenser. It even had the ability to heat and cool different zones of the system at the same time. The system was called a Variable Refrigerant Flow system or VRF.
I was a young sales engineer at the time and I understood those words but my mind had a hard time comprehending how that could work. I went to the job site and took these few photos with my Sidekick 3. I didn’t know it at the time, but I ended up concentrating on and spending the majority of my career on VRF.
Back then, it was a new technology and even today in 2024, it still is considered “advanced” or “complicated” (at least in the United States). I’ve spent the last 10+ years selling, educating, and advocating the benefits of VRF and I can trace it all the way back to that job site visit.
