• NCI analyzer kit that includes a Testo digital static pressure manometer, probes, test port installation kit, and test port plugs
  • For air conditioning, they need solid electronic charging gauges. I’ve found that most of these work well, so I let the techs choose and buy the ones they prefer
  • Water pressure gauges: We provide this so they can check water heaters and boilers.

We love the NCI kit as well as all the training that NCI provides. The training and tools we’ve acquired from NCI over the years helped me to turn my business around years ago.

One last thought: by controlling our truck inventory, we could change how we stage jobs each morning. With R.E. Michel’s ESP, we can get our HVAC techs in by 7 a.m. and out by 8, then bring in our plumbing techs. Before understanding the inventory of trucks, we tried to stage everything together, and it was complete madness.

As I stated at the beginning of this article, one of the most significant benefits of truck inventory management is that we’ve improved productivity so much that we can get one extra job per tech per day. We measure success by using billable hours as a key performance indicator. And we are seeing that number increase.

Maintaining proper HVAC service truck inventory is essential for optimizing efficiency, enhancing customer satisfaction, and controlling costs in the HVAC service industry. I believe that if you follow the guidelines outlined here and regularly evaluate and adjust your inventory management practices, you can ensure your service team is equipped to handle any job that comes their way.
