Think You Know Your Stuff?
Written the same way I'd quiz a new tech on the job. Every question has an explanation — the point is to teach, not to trick. Pick a topic and see where you stand.
Chiller Plant Fundamentals
Test yourself on approach temps, kW/ton, refrigerant circuits, and the fundamentals of chiller plant operations.
Air Handling & Distribution
AHUs, VAVs, static pressure, economizers — the airside is where comfort meets the ductwork. See if you really know what's happening between the fan and the diffuser.
Building Automation & Controls
BACnet, DDC, PID loops, and the digital backbone of modern buildings. Test your knowledge of building automation systems and controls.
Cooling Tower Water Treatment
Cycles of concentration, biocide programs, legionella prevention, and blowdown controllers — how well do you really understand your water treatment program?
Steam Traps & Energy Waste
Failed steam traps are the biggest hidden energy waste in commercial buildings. Test your knowledge on trap types, failure modes, testing methods, and the real cost of ignoring them.
DDC Controls & Wiring
From 24V power supplies to shielded cable runs, BAS wiring mistakes cause more callbacks than bad programming. Test your knowledge on the wiring fundamentals that keep buildings running.
