As an HVAC (Heating Ventilation and Cooling) technicians, you need the right tools for the job. This is especially true when doing HVAC service to a home or business.

Some HVAC tools are not so obvious and the homeowner may end up purchasing the wrong one. This can cause a problem down the road when it’s time to go back for a follow-up service.

Also, to do your job right, you want to make sure you have the right tools for your HVAC system.

We’ve put together this handy guide to help you figure out what tools you need. This guide will cover the basic tools you need as well as some of the more advanced tools you can use.

All the tools I recommended are the ones I used in HVAC service and I recommend them to anyone who is getting into HVAC work.

Straight sided wrenches may take forever to find in your garage, but not with the 31100 model from RIDGID. Another low profile tool that’s also light in weight, the 31100 takes up very little space in your toolbox. But don’t for a minute think that this set of wrenches isn’t built to last. It’s made of heavy duty aluminum, which makes it pretty tough.
