What is a tinner? A tinner is someone who assembles the duct portion of a project. That’s the short answer. I worked the tinner trade for about four years, and I’ve been in construction for more than twenty. These days I manage construction projects in Salt Lake.
What Is a Tinner on a Job Site
A tinner assembles the duct portion of a project. That’s the core of it.
My own experience went broader than that. I also worked on furnaces, condensing units, and controls wiring on small systems. I did troubleshooting too, the easy fixes. But the duct is what the name is about. If you want to see what goes in the bag for that work, here’s my list of duct tools.
Where the Name Tinner Comes From
Other trades call us that. From a union perspective, tinner is a skill set of people.
Outside of unions, it was more common for us to refer to ourselves as HVAC installers (some even say HVACR). Same work. Different name depending on who’s talking. So the answer to what is a tinner depends a little on who you ask.
A Normal Day for a Tinner
Meet at the shop. Prep material for the day. Go to the site and install.
When I first started, we met at the shop if in town and then carpooled to the job. I’d sort and assemble duct, then hang it. That was the work.
When we traveled, and this was often, we all met at the breakfast room and went to the job from there. Anywhere we went the work was the same. Bang on duct and hang it.
Then I learned to build offsets. If you want the math, here’s the 3-4-5 duct offset calculator. After that my day changed. I’d measure the offsets needed the night before if I could not build them onsite. Make them in the morning for an hour. Go to site. Then continue on with the same work of banging duct together and hanging it. Here’s more on how to connect rectangular ductwork and hanging duct by yourself.
Shop days
There were days we had a bunch of us in the shop making duct. We took it from the flat metal at the shear to gluing on the insulation. Then we packed it up for a road trip project. We would spend the whole day making duct.
The owner would BBQ. It was dirty work, and the free lunch was a great perk.
As time went on, we got a crew to make duct in the shop. I didn’t do production after that. Just offsets.
What Nobody Tells You About Being a Tinner
The work starts easy. Hanging duct, climbing a ladder, cutting an offset on the floor, none of it is hard the first week. What nobody tells you is what the repetition does to you, day after day.
You lift and work overhead. You climb up and down ladders all day. You stoop and kneel on the ground cutting offsets in the field. Over time the pain gets more frequent. I remember coming home hurting all over and just lying down.
It wears you down mentally as well as physically, and that’s the part people don’t see coming. It’s a big reason I went back to school and moved into project management.
How to Become a Tinner
I’ll be straight. I actually don’t know what it takes now. I got hired and started working. After my body hurt every night, I went to school. It was hard to take the tools off but moving into project management was right for me and my family.
If schooling is where you want to go, there are certifications and apprenticeship programs that you can chase. Or see if you can get hired on with a local company.
Honestly, a lot of the questions I see from new guys are things you pick up fast on the job, and you get paid while you learn them. If you’re thinking about the trade, don’t let the classroom part scare you off. The real learning happens hanging duct.
If you’re starting out, the basics still matter. Start with my hand tool essentials.
What a Tinner Apprentice Carries
Knowing what is a tinner is one thing. Showing up ready is another. If you want to know what a first-year should have on them, I covered that in sheet metal apprentice tools.
FAQ
What is a tinner?
An HVAC tinner is someone who assembles the duct portion of a project.
Is a tinner the same as an HVAC installer?
Outside of unions, it was more common for us to call ourselves HVAC installers. Other trades call us tinners. In the union, tinner is a broad label for a skill set of people. I have never worked for a union but have worked with union contractors on the management side.
Does a tinner only work on duct?
The duct is the core of it. My own work also covered furnaces, condensing units, controls wiring on small systems, and troubleshooting easy fixes. In my opinion, just working on duct would get pretty repetitive, and I would need some flavor. I evolved into controls, brazing line sets, balancing, troubleshooting and service. It was a lot more challenging and a lot more fun.
Do tinners make duct in the shop?
We did. Some days a bunch of us made duct in the shop all day, from flat metal at the shear to gluing on the insulation. A part of tinning is in the shop and those jobs are available to just build duct. We had a whole team of them.
Is being a tinner hard on your body?
Yes, but not right away. The work starts easy. What gets you is the repetition: lifting duct overhead, climbing ladders all day, and kneeling on the ground to cut offsets. Over time the pain shows up more often, and I remember coming home hurting all over and just lying down. It wears on you mentally too, and it’s a big part of why I went to school.
