The HVAC Technician Tool List in 2023!

It doesn’t matter whether you’re the worlds’ most experienced or respected HVAC technician. OR, if you’re starting out in the industry. If you don’t have the right HVAC service tool list checked out, you won’t manage to meet your clients’ needs. But, before you stock up your tool bag with all the tools you think should go into it, stop.

Let’s do a little strategic thinking here. What essential tool do you think you can’t do without? As an HVAC technician, you should have at least proper footwear and safety goggles. You will also need gloves, and basic tools to show that you’re a professional in your field.

If you’re working for an HVAC business, your employer will provide specialized devices. These will help you get the job done. The equipment they provide may be too expensive for you to buy on your own. But, it would be best if you were always prepared to have some HVAC hand tools. This is so that you can prepare to handle all the jobs that you come across.
We did a little research and threw some feelers to some experienced technicians we know. We asked them what tools they would need to make up the best HVAC tool list, and here is what we came up with.

You will find these tools in the plumbing industry. But, you’re still going to use them in HVAC systems. You will use a pipe wrench and pliers to manipulate or fold wiring.

Some of the pliers you will need are open face, needle-nose, and wire stripper pliers.

Shears and Tin Snips

If you aren’t familiar with how HVAC technicians work, you may have confusion at how much precision they need to do their job. The best example of this is while charging an air conditioning unit. If you put in too little refrigerant, your system will not maintain the required temperature. If you put in too much, the system will have excess pressure in its cooling equipment. This will strain the compressor too much and lead to the shortening of its lifespan.
Too much pressure will lead to constant maintenance issues. When you use a refrigerant scale, you can avoid such issues. Do this by measuring the exact amount of refrigerant you need to add to the compressor. You will have the exact information you need to add what the system needs.

These tools will help you to check whether there are leaks in the system. They will allow you to fix any problems you encounter before they get out of control. Like vacuum pumps, there are different types of refrigerant scales. Before you buy one, ensure that you have researched its benefits to know how it will serve you.
