How to Troubleshoot an HVAC Tool Kit

Search for empty spaces in your tool kit, if tools are kept in an organized set. Empty spaces mean missing tools that require replacement if you can't find them. This prevents you from being short a tool when you need one during an HVAC repair.

Check the batteries on the flashlights and on gauges that have batteries. This makes sure the tools don't run out of power when you need them most. Replace the batteries in each tool once a year to ensure the power supply is always fresh.

Inspect the metal tools, like screwdrivers and wrenches, for rust and corrosion. Apply fine sandpaper to the tools to remove any small rust spots. Heavier rust requires the use of a rust remover to make the removal easier.

Lubricate the joints of tools like pliers and wrenches with lubricating oil if they don't move smoothly.

Tap on the casing of any gauges that are stuck. Slight vibration often dislodges a stuck needle and loosens it so the gauge reads properly again. Tighten any loose fittings on the gauge to prevent leakage when the gauge is hooked up to the AC system. Inspect any hoses connected to the gauge. Replace any hoses that are breached or corroded to eliminate leaks that negatively affect a gauge's reading.

Replace any tools that don't work properly. This ensures that you maintain a complete set of HVAC repair tools.
