Commercial AV
A commercial room has to work while other people are watching. A conference room that drops the far end mid call, or a taproom showing the wrong game on two of five screens, costs you something a living room never does. Most of what decides that is the building rather than the gear: metal studs, a grid ceiling, and how far the source equipment sits from the screen. I ran audio, video, lighting and carpentry for touring live entertainment starting in 2023 and moved to corporate entertainment in 2026, so racks, long cable runs and working on someone else's schedule are familiar ground.
$40 an hour, 1 hour minimum. Every visit is billed at least one full hour even if the work takes thirty minutes. Why, and how to get the most out of it.
What the job involves
- The first thing I do in a commercial room is push a ceiling tile up and look. Cable is not allowed to lie on the tiles, so it gets hung from the deck on J hooks, and if that ceiling is a plenum return the cable has to be plenum rated. The HDMI cable that came in the box is not.
- Runs in a business are long. Passive HDMI gets unreliable somewhere past twenty five feet, and sooner at 4K and sixty hertz. Longer than that the run becomes Cat6 with a transmitter and a receiver, or an active fiber HDMI that only carries signal one direction and has to be pulled with the marked end at the source. Up in a ceiling, guessing wrong means pulling the cable twice.
- Commercial partitions are usually light gauge metal stud, and a lag screw in one of those holds nothing. A large display needs a plate spanning two studs, hardware rated for the load, or backing added before the drywall closes. Block takes sleeve anchors. A glass or demountable partition takes nothing at all, which is worth knowing before the display is bought.
- In a meeting room audio is the harder half, and it is the half that gets specified last. One laptop microphone at the end of a hard surfaced table does not cover eight people, and a camera at the display with a laptop at the table is farther than passive USB carries, which is about three meters for USB 3. That run needs an active extender or a device that puts itself on the network instead.
- Feeding several screens from one box drops every screen to the weakest one unless the splitter manages EDID, and separate games on separate screens means a separate source per screen, not a splitter. Deciding what shows where, and where the boxes live so they can vent and be reached, happens before anything gets mounted.
- An event is three blocks of time instead of one. Load in and set up the PA, microphones and lights, run it while it is happening, then strike it and be out on the venue's clock. Carpentry is part of that too: a riser, a podium front, or getting cable across a walkway in a way nobody trips on.
What changes the price
The cable path moves the number more than anything else. An accessible grid ceiling with room above it is quick. A hard drywall ceiling, a block wall, or surface raceway because there is no path at all turns minutes into hours. After that it is the count of displays, the distance from the gear to each one, whether a wall needs backing before a mount goes on it, and whether the equipment already bought is the right equipment. Working after close bills the same $40 an hour, but a room that can only be down from ten at night until six in the morning takes more trips than one I can work straight through on a Tuesday.
What people usually get wrong
Buying the equipment before measuring the room. There are two versions of it. Consumer televisions go into a space that runs them open to close, and a consumer warranty generally covers home use, which a taproom running a set fourteen hours a day is not. Or an HDMI cable gets bought long enough to reach, at a length where it drops out, and the display gets blamed for it. Send me the distances and what the room does all day and I will tell you what to buy before you spend the money.
Send me this and I can quote it without coming out
There is no trip charge either way, but a remote quote is faster for both of us and it costs you nothing to try.
- A photo with one ceiling tile pushed up, so I can see whether there is a path above it and how much room is up there.
- A photo of each wall a screen is going on. Drag a magnet across it first and tell me if it grabs every sixteen inches, which means metal stud.
- The distance in feet from where the equipment will live to each display, measured along the route a cable would take rather than straight across the room.
- Model numbers of anything already purchased: displays, mixer, camera, receivers, cable boxes. If nothing is bought yet, say so. That is the better position to start from.
- The hours the room can be out of service and which days. That decides how many nights this takes.
When I am the wrong call
I do not do the electrical. No new circuits, no outlet added behind a display, no conduit. That is an electrician's work and on a commercial job it usually has to happen before I show up. Anything tying into the fire alarm, such as ceiling paging that has to mute when the alarm sounds, belongs to a fire alarm contractor and not to me. And there is only one of me. If a dark conference room costs you real money that morning, hire a company with a service agreement and a second technician.
