Huff's Kool Bus Preferred Tool Kit with Indoor and Outdoor Smart Probes, Electrical Testing, and Veto Tool Bag
Huff's Go-To HVAC Diagnostic Kit
Bring Huff's everyday diagnostic setup to your next service call. Drawing on the tools he uses at NextGen HVAC Academy and Huff's Kool Bus, this kit combines his preferred wireless probes, electrical meters, and accessories in a Veto Pro Pac SB-LD bag. Huff mixes brands to get the features he values most: easy-to-read displays, access to tight spaces, durable construction, and compatibility with measureQuick. Multiple probe sets let you keep key measurements connected, check additional points, and have a backup ready, helping you work through air-side, refrigerant, furnace, and electrical diagnostics with fewer tool changes.
Key Features & Benefits
- Air probes for different jobs: Two slim Fieldpiece probes fit tight supply and return registers, while the JB probe's built-in display makes outdoor readings and quick room checks convenient.
- A complete furnace setup: Fieldpiece manometers handle incoming and manifold gas pressure while the Testo 510i measures total external static pressure, reducing the need to disconnect and reposition tools. Compact Retrotec static probes help with tight access.
- Flexible refrigerant diagnostics: JB pressure probes provide on-tool readings and built-in charging tees. Fieldpiece temperature clamps offer the grip and durable sensor construction Huff prefers, while a third JB clamp adds a display, backup, and another measurement point for discharge-line, heat-pump, or restriction checks.
- Electrical measurements that matter: Huff chooses the UEi HAC meter for its resolution when checking low-wattage loads such as smaller ECM blowers.
This mixed-brand approach brings these measurements together in measureQuick for a more complete view of system performance.
Masterclass, hands-on HVAC training—delivered directly to your location
