Below is a list of essential equipment that every air conditioner technician should have in their toolbox. With these tools, you’ll be able to service any AC unit with ease!

AC Tools#1: Gauge Manifold

Gauge Manifold

A manifold gauge is a must-have tool in any AC technician’s arsenal that measures pressure changes in gases and liquids such as air conditioning refrigerants.

The refrigerant’s temperature and pressure are displayed on the manifold’s gauge, which can then be used to diagnose problems with the AC unit.

This little device can tell you if your air conditioner is working properly, or whether there are leaks in the gas line. It comes in handy when it’s time for a refrigerant change or removing refrigerant from the air conditioner. It’s also very useful when performing maintenance on an older AC.

AC Tools#2: Digital Clamp Multi Meter

Digital Clamp Multi Meter

The digital clamp multimeter is a device that can measure voltage, current, and resistance. It has an LCD display that shows the results of the measurements taken by the tool in numerical form.

Digital multimeters are used to test electrical circuits for continuity (whether they are open or closed), as well as other tests such as measuring AC/DC current and voltage levels.

While servicing an Air conditioner, a digital Clamp Multimeter is used to check the ampere and voltage reading.

AC Tools#3: Nose Plier or Pilas

Pilas or Nose Plier

A plier is a tool that is used to grip or hold objects. There are many different types of pliers available, each with its own unique purpose. Pilas (or needle-nose pliers) are a type of plier that has a long, thin nose. They are ideal for gripping small objects such as wires or screws.

Pinch pliers are a type of locking pliers that have two serrated jaws which can be locked in place to hold an object firmly. They are also called Channel Locks, Vise-Grips, or C-Clamps. The jaws are opened and closed by squeezing the handles together.

This is a very common tool and is generally used to remove the outer covering of wires. It is an essential tool for servicing air conditioners.

Pinch pliers are used to hold small objects such as nuts and bolts in place while tightening or loosening them. They’re often called needle-nose because of their long, thin jaws that can reach into tight spaces where other tools wouldn’t fit!

AC Tools#4: Screw Driver

Screw Driver

A screwdriver is a basic but essential tool for any technician servicing air conditioners. This tool is used to remove and install screws of various sizes. Screwdrivers are used to tighten or loosen screws, nuts, bolts, and other fasteners. It can also be used for removing panels or covers and prying objects open.

They come in many different sizes, shapes, and types to accommodate various tasks. So require one that can fit your needs perfectly!

There are two different styles of screwdrivers: flathead (straight edge) and Phillips (crossed slots).

  • Phillips Head or Crossed Slot screwdriver
  • Flathead or Straight Edge Screwdriver

Flatheads have either a single slot on top for driving screws into the woodwork; while Phillips heads feature two slots at 90 degrees from each other allowing them to drive more securely than flathead screwdrivers.

It is one of the most basic tools needed by any technician. So, make sure you have a Phillips head and flathead screwdriver in your toolkit!

AC Tools#5: Screw Wrench

Socket Wrench Set

A wrench is a tool used to tighten or loosen nuts and bolts. It has an adjustable jaw that can be moved up and down, so the size of the nut/bolt head it fits over changes accordingly.

There are two types of wrenches: open-end (which has two jaws with teeth on each side) or box-end (which only has one jaw).

Box end wrenches are typically longer than their open counterparts because they allow you to apply more force when turning nuts/bolts while still maintaining control over how fast they’re going around in circles!

  • Allen wrench set
  • Socket wrench set

These are two additional toolsets that can be extremely useful when working on air conditioners.

Allen wrenches are used for tightening or loosening screws with an Allen key head, while socket wrenches are perfect for turning bolts or nuts using a ratchet handle.

Make sure you have these two sets handy the next time you need to work on your AC unit!

AC Tools#6: L Key Set

L Key Set

The L key set is a collection of hex keys (aka Allen keys) that come in different sizes and shapes. These keys are used to tighten and loosen bolts and screws with hexagonal sockets in them.

Hexagonal type of screw is common on many appliances and machinery. It is also present in an air conditioner. So, it’s important to have a set of hex keys on hand for servicing an air conditioner. A L key set is an essential tool for any technician who works on air conditioners.

AC Tools#7: Vacuum Pump

Vacuum Pump

The vacuum pump is a device that creates a vacuum (a space with reduced air pressure) in order to suck or pull fluids and gases out of containers or systems.

It is commonly used in mechanical engineering and automotive repair to remove oil, water, or other unwanted fluids from engines, transmissions, and other components.

In AC servicing, it is basically used to create a vacuum in the refrigerator refrigeration lines before charging the refrigerator gas. With the help of a vacuum pump, an AC technician can remove contaminants from refrigerant lines by creating an area of low pressure inside them (this process is called “vacuuming” or “Evacuation”).

This tool is essential for air conditioner technicians as they need to be able to remove all traces of moisture from an air conditioner before recharging it with refrigerant. It also helps ensure the integrity of your AC unit after servicing has been performed!

AC Tools#8: Mini Gas Welding Machine

Mini Gas Welding Machine

Welding is a process of joining metal parts by heating the surfaces to the point where they melt and flow together. A mini gas welding machine is an essential tool for any air conditioner technician.

A mini gas welding machine is a small portable and easy-to-use tool that uses oxygen as fuel for cutting metal with an electric arc. It is perfect for welding and repairing thin sheet metal, and because it’s small and lightweight, it can be easily transported to the job site.

This device uses a small, handheld torch to heat the weld joint, melting the two pieces of metal together.

AC Tools#9: Torch


A torch is another essential tool for air conditioner technicians. A torch is a handheld device that uses an open flame to heat up metal parts so that they can be welded or soldered together. A torch can also be used to cut through metal sheets.

Torch flames come in many different shapes and sizes (butane, propane, acetylene) and are used for a variety of applications including metalworking, jewelry making, cooking, and even tattoos!

AC Tools#10: Swaging Tool

Swaging Tool Set

A swaging tool is a device that crimps or deforms metal tubing so that it forms a tight seal. It is often used in plumbing applications to join two pieces of copper pipe together without using solder.

Swaging tools come in many different shapes and sizes, but all of them work on the same principle: by pushing one end of the tube into another until it reaches its maximum depth; at which point an internal hammer strikes down against anvils inside the device to complete this process.

In Ac servicing, it is mostly used in connecting two copper pipes together by increasing the hole size of a copper pipe. It is essential for air conditioner technicians as they need to be able to securely attach fittings to tubes.

AC Tools#11: Level

Level Tool

The level is a device that measures whether or not something is straight up and down (horizontal), left-to-right (vertical), or forward and backward (slope).

It can be used in construction, carpentry, plumbing, masonry, and other trades where precise measurements are required because they ensure accuracy when drilling holes through walls etcetera.

In AC servicing, this tool is essential to ensure proper leveling of the indoor unit. A magnetic version of the level is good.
