Essential Tools For HVAC Techs


A person seeking a career in the HVAC industry requires the use of many different tools on the job. As with other technical trades, an HVAC technician usually owns his/her own personal set of hand tools that travel with the tech from job to job and employer to employer. If you are still a student, most HVAC schools provide you with a list of the basic tools you’ll need to have during your coursework. Additionally, there are some specialized instruments and gauges required for HVAC work. Generally the more expensive ones will be supplied by your future employer, but not always. You will need to build your own Tools for HVAC Techs collection.

The collection of hand tools you need depends on whether you’ll be working as a service technician, an installer, or both. You’ll need some basic hand tools, general electrical tools, and a variety of specialized HVAC tools, including some gauges. As you shop for your tools, remember what their purpose for your will be. These tools will enable you to make money. As such, don’t be cheap and skimp on what you’re willing to pay for them. It is much better to pay more initially and get sturdy dependable tools that will service you for years that pay less for ones that will break on the job and need to be replaced. From beginning HVAC students to experienced professionals, you can anticipate investing from $300 to $2000 in your tool collection.
