Doors that never stop opening: how the ducts of a store or a supermarket are reviewed
A store receives people and goods all day, and its air conditioning works against doors that keep opening.
By Limpieza de Ductos Panamá
Short answer
Duct cleaning in a store or supermarket is the camera inspection and cleaning of the ducts over aisles, checkout and stockroom, done at night or in low traffic hours and by zones of the premises. Cleaning is decided from what the camera shows.
What sets stores and supermarkets apart
Constant entrancesEvery door that opens brings in air from outside. That is why returns and filters near the entrances are checked.
Closing hoursThe work is scheduled by zones in closing or low-traffic hours.
A stockroom next to salesThe stockroom may share part of the air with the sales area. The place where they join is checked.
Facts that help decide in stores and supermarkets
- In Panama: INEC’s Business and Establishment Directory (reference year 2022) records 39,937 wholesale and retail trade establishments, including Free Zones, and vehicle repair, the sector with the most establishments in the country, out of 96,397. The category is broad and does not separate supermarkets or stores. (INEC, Business and Establishment Directory 2022)
- Technical fact: A field study in two US supermarkets (ASHRAE Transactions, 1999) measured that lowering the store’s relative humidity lowered refrigeration system energy use, about 10 kWh per day for each 1% drop in one of the stores. They are two stores measured decades ago in another climate, and not a savings promise. It shows that the humidity handled by the air conditioning affects refrigerated cases. (Henderson and Khattar, ASHRAE Transactions, 1999)
Types of place within stores and supermarkets
| Type of place | What changes in the work plan |
|---|---|
| Supermarkets | Ducts over the aisles and the bakery or kitchen area |
| Convenience stores and corner shops | The main unit and filter, in a short visit |
| Chain stores | Each store is looked at separately, because its duct run changes |
| Department stores | A plan by zones inside the store |
| Appliance stores | Returns of the main showroom |
| Hardware stores | Filters and returns near the stockroom |
| Car dealerships | Showroom units and separation from the workshop |
| Duty free shops | Ducts of the sales area and the stockroom |

How the work is organized in stores and supermarkets
- Look inside. The camera runs through the ducts of the sales area and the stockroom.
- Schedule by zones. The manager agrees which zones are worked on each night or in low-traffic hours.
- Hand over the report. With photos by zone and with what could not be seen.
An example of what the report brings
An illustrative example of a supermarket report: a sketch of the premises by zones, with photos of the ducts over the refrigerated aisle and the stockroom, and the suggested order to work one zone per night without affecting opening.
What you are left with at the end
- A plan by zones and hours, agreed with the manager
- Photographs of the inside of the ducts
- The list of sections with no access
- A suggestion of when to check again, based on the traffic of the premises

Frequently asked questions
Does the store have to close?
Not necessarily. The work is done at night or by zones, in low-traffic hours, so sales go on.
Are the stockroom ducts checked as well?
Yes. Those of the stockroom are checked, along with the point where they join those of the sales area.
Is the work different in a large supermarket?
The scale changes: more zones and more nights. The method is the same, camera first and cleaning afterward, if needed.
Does it apply to a car dealership?
Yes. The showroom units are checked and the workshop air is kept apart from the sales area air.
How often does it make sense to check the ducts in stores and supermarkets?
There is no fixed frequency. It makes sense to look when there are odors or moisture in aisles or stockroom, and before busier seasons.
What does the report include for stores and supermarkets?
It brings photographs of the inside of the ducts. It is handed over by zone of the premises, so the manager can schedule what comes next.
