Howard: call center with 24 hour shifts, when are ducts checked?
In a call center with 24 hour shifts there is no maintenance day. The operations manager in Howard needs to know when the ducts can be opened without leaving a hundred agents without air.

The ducts of a Howard call center are checked by work area and not by building. The floor is divided according to the duct runs serving each group of desks, training rooms, break areas and canteen, and each area is worked in its lowest staffing window, which operations knows better than anyone. While one run is inspected, the rest of the floor keeps taking calls with its own air.
Howard was an air base from 1942 until it reverted to Panama in late 1999, and today its 1,400 hectares are part of the special economic area created by Law 41 of 2004. Among the offices of the former base there are call centers that run without interruption. For duct maintenance that changes the question: it is not when the center closes, because it does not close, but when each run of the system has the fewest people under it.
Continuous shifts: the floor is never empty
An agent floor works with a high density of people and equipment, and the air conditioning runs all day. ASHRAE 180, the standard for inspection and maintenance of commercial HVAC systems, starts from the idea that maintenance is scheduled and recorded, not improvised when something fails. In a Howard call center that program is written over the occupancy curve: there are early morning or weekend hours when an area is left with a fraction of its staff, and those are the windows.
The answer is not to shut the whole system down at the lowest hour, because one area’s lowest hour may be the peak of another that serves a different time zone. That is why work in a call center is organized as if it were several small buildings sharing a roof.
Behind this guide is Climatiza, an inspection and duct cleaning service, which always starts from the real condition of the system before proposing any work in Howard.
Dividing the floor by work area
- Diffuser plan by area. It is marked which diffusers and returns serve each group of desks, each training room and the break areas. If there is no plan, it is mapped with cold smoke and a camera on a first visit.
- Staffing curve by area. Operations hands over, for each area, the weekly slot with the fewest agents. That slot, and not a fixed hour, is the work window.
- Dampers and isolation. Before opening an access panel the branch damper is closed and its return is blocked, so the rest of the floor does not receive what moves in the run.
- One area per visit. Each visit covers a single area from start to finish, with grilles back in place and the damper open before the next shift arrives.
What to check in agent rooms and break areas
Each area of the center accumulates something different. The agent room concentrates people, screen heat and paper dust. The break room adds microwave steam and food scraps next to the return. The canteen, if there is one, adds fine grease. Checking the three with the same criterion wastes time on what is not needed.
| Area | What is checked first | Usual window |
|---|---|---|
| Agent room | Returns between desk islands and the filter of the air handler serving them | That group’s lowest staffing slot |
| Training room | Diffusers over the tables and first run, because it spends days closed and days full | Days with no scheduled session |
| Break area | Return next to the microwave and coffee maker, grille with grease and steam | Between shift changes |
| Canteen | Point where the canteen duct joins the floor duct | Outside meal times |
| Equipment and server room | Own filter and condensation in the run serving it | With the technology lead present |
For the agent room the figure that weighs most is the condition of the air handler filter. The ASHRAE preventive maintenance checklist for air quality recommends reading the filter pressure drop every month and replacing it when it exceeds the manufacturer’s maximum. In a center running 24 hours that monthly reading equals many more hours of use than in a normal office, and it should be noted in the same log where the duct check is recorded.
Coordination with operations and human resources
In a call center the duct contractor deals with two counterparts. Operations sets the windows and knows which campaign cannot lose a minute. Human resources informs the agents, because a technician in the ceiling during a call generates complaints if nobody announced it. Building management in Howard adds entry to the site and the equipment loading schedule. An office with several tenants on the same floor needs the same coordination, with the difference that there an empty night does exist.
- Notice to the agents in the area one day ahead, with start and end time.
- Equipment route across the floor agreed with operations so it does not cross islands in service.
- A shift supervisor present in the area while work goes on, able to stop the task if a campaign requires it.
- Quiet tools in the run over the desks. The rotary brush is kept for windows with no agents underneath.
- Time in and out logged per area, for the maintenance book and for human resources.
Report for the center management
Management wants to know three things per area: what condition the run was in, what was done and when to look again. A report with one sheet per area, the images from the camera inside the duct before and after, the filter reading and the window used allows the next cycle to be planned without arguing dates again. Pending areas are loaded into the planner that orders checks by floor zone and the center can repeat the round with another contractor or the same one without losing the thread. Whoever manages another building in the former base can see how operating shifts are coordinated in Howard to adapt the scheme to their case.
The next step after this guide is usually a visit to check the system, which is arranged with the team at Climatiza using the details in their duct cleaning page.

Frequently asked questions
Does the floor air have to be shut off to check the ducts?
No. The damper of the branch serving the area being worked is closed and its return is blocked. The rest of the floor keeps its air. Only the group of desks under that run notices the change, which is why its lowest staffing slot is chosen.
How often should the ducts of a center running 24 hours be checked?
No rule was found that sets a deadline. The practical rule is to read the filter every month, as the ASHRAE checklist suggests, and run the camera through the first run of each air handler once per season. Cleaning is decided from those images.
Can work go on while agents are taking calls?
In neighboring areas yes, with quiet tools and the equipment route agreed. Over desks in service only inspection is done. Mechanical cleaning of that run waits for the window with no agents underneath.
Who authorizes the visit, operations or the building manager?
Both. Operations authorizes the window and the area, and the building manager in Howard authorizes entry to the site and the equipment loading time. Human resources does not authorize, but informs the agents.
