Basic Aircon Unit Repair Tools

When it comes to repairing your aircon unit, aside from calling a professional aircon servicing company in order to have it properly done, it would also be right if we would get to know the tools and equipment being used in repairing them. This will be useful and helpful especially during emergency situations or when you need to perform a quick or DIY repair at home. Let’s get to look at the basic tools used for aircon unit repairs:

Allen Wrench

This is often used if you have a window-style aircon unit. This is a tool that will be required for removing the squirrel cage fans. It is an angled hexagonal tool that is made of hardened steel.

Copper tube blender

In order to bend the copper tubes nicely, you will require a copper tube blender. This tool will have 3 size molded round wheels and it helps in molding the copper tube without any chances of cracks.

Electric Drill

Drills are primarily used for drilling circular holes in the material, or for inserting screws and other threaded fasteners into the material. You must use 18V at least. This electric drill requires a charger and two batteries. You will find that a high-quality drill will be costly but do not compromise for that as a good drill will serve you later and make it worthwhile for every money that you spend.

Electrical Testers

While repairing the aircon unit, it is obvious that you will be working with electricity. Thus, it is a must that you have electric testers handy. Before you start working you should always test the electricity condition with the help of an electric tester.

Hex-head nut drivers

The nut drivers come in handy when you have to drive any hex bolts or remove them. They are most helpful when you have to remove nuts from any deep-seated place. For repairing your aircon unit you will require 5/16 inch, 3/8 inch, and ¼ inch sizes.


You will require a lever for different works associated with your aircon unit. You may choose a magnetic lever that will let you work freely while you are leveling.

Measuring tape

Whether for measuring the length of the copper tube or the volume of the room you will require a measuring tape. It is best to have a steel measuring tape that will be durable and long-lasting. The ideal length of the tape measure should be at least 7m.


Pliers too will be required when you start repairing the aircon unit, especially when you have to remove a clip from any hard-to-reach place of the aircon unit. It is good if you can buy a whole set of pliers but if it is not feasible then buy the long nose plier. One with a long pointed nose will suffice the need.


Depending upon the type of blade you have on your Sawzall Saw, you can do almost anything with it. You must invest in one that is durable with a charger that keeps the batteries charged. Investing in a quick-release blade system seems more feasible.

Screw Drivers

This is the most essential tool for any DIY project. Most aircon repairs in Singapore will require different types of screwdrivers for opening the nut bolts. They are available in different sizes and shapes. It is best to use screwdrivers that have insulated handles that will protect you from any kind of shock. For aircon repair, the most effective screwdrivers are the 3/16 inch and the 1/8 inch ones.

Tube Cutter

You will require a tube cutter in order to chop the copper tune of the aircon unit. The tube will be around an eight-inch to half-inch in diameter. You can adjust the cutter to cut tubes of any size easily. You need to be very careful while cutting the tubes as excess pressure may damage the copper.

Here are other various tools that you will need for your aircon unit repairs:

Domestic AC/Fuel disconnect set

– Universal valve core remover

– Adapter fittings
