Don Bosco: new house next to a building site, how to protect the ducts
Moving into a new house in Don Bosco with a crane next door is increasingly common. Dust from the neighboring works does not ask permission to enter the freshly installed ducts.
By Limpieza de Ductos Panamá
The ducts of a new house in Don Bosco are protected from the neighboring works on three fronts: an extra filter layer over the return grille, more frequent filter changes while construction lasts, and closed windows on the works side during cutting and demolition hours. When the works end, a camera inspection confirms whether fine dust got in and whether cleaning is needed or just a filter change.
Don Bosco is a young district: Law 42 of 2017 split it from Juan Díaz, and the 2023 census already counts 49,906 residents in just 16.8 km², almost 3,000 per square kilometer. With the Don Bosco station on Metro Line 2, the remaining land gets built fast. That produces a repeated situation: a family moves into its new house and, ten meters away, another project starts digging.
Neighboring works and fine dust entering through the return
Construction dust comes in two sizes. The coarse kind, from excavation and blocks, falls nearby and shows on the car and the windows. The fine kind, from tile cutting, joint compound sanding and cement mixing, floats for hours and enters through any crack. Inside the house, the air system picks it up through the return grille and pushes it through every duct. The filter stops part of it. What gets through settles on the duct walls, where the 75.7% mean humidity of Panama, according to ETESA, fixes it in place.
The EPA and NIOSH Building Air Quality guide, when discussing works in occupied buildings, recommends blocking return registers near the work zone so contaminants are not recirculated. The principle applies just as well when the works are on the next lot: the return is the door to watch.
Anyone who needs to see the real condition of the ducts in the case of Don Bosco can request a camera inspection from the team at Climatiza, a technical duct cleaning service in Panama, which documents every section with images.
Signs in a recently occupied house
- Fine white dust on dark furniture the day after cleaning, more in rooms on the works side.
- Return filter light gray in two weeks, when in a new house it should last months.
- Supply grille vanes with a dusty edge in a house that still smells of paint.
- A cement or stone cutting smell when the air comes on in the afternoon, after working hours.
- Windows on the works side with a gray film in the sliding track.
What to check before and after the neighboring works
The best defense is a reference photo. A new house should have clean ducts, but that is not always the case: dust from its own construction may have stayed inside. That is why it makes sense to look with the camera at the start, before the neighboring works advance, and look again when they end. Comparing the two images decides whether cleaning is needed.
| Moment | What is checked | Purpose |
|---|---|---|
| Before the neighboring works advance | Return, first run and one grille per room with the camera | Set the starting condition with dated photos |
| During the works, every month | Filter, extra return layer and frame | Replace what is loaded |
| When the works end | Same points as at the start, with the camera | Compare and decide whether to clean |
Temporary protection of grilles and intakes
- Add a prefilter layer over the return grille. A sheet of filter media cut to size and fixed to the frame holds coarse dust before the main filter. It is changed every two weeks during the cutting and sanding months.
- Seal the main filter frame. A foam strip along the edges keeps fine dust from going around the filter, the most common failure in new houses with loose frames.
- Shield the outdoor intake if it faces the works. A deflector or filter mesh reduces direct entry. If the intake can be closed during demolition hours, better.
- Close the supply grilles in unused rooms. Fewer open grilles on the works side means fewer points where dust enters while the unit is off.
Frequency while construction lasts
While the neighboring works are active, cleaning the ducts makes no sense: they would be dirty again within weeks. The useful frequency is the filter one, every two to four weeks depending on the construction stage, with excavation and tile cutting as the toughest months. The camera inspection is reserved for the start and the end, and cleaning, if the camera justifies it, for after the neighboring project is delivered. It pays to review the criteria for knowing when a duct needs cleaning before deciding.
If the house is in a gated complex, the administration usually has contact with the neighboring builder and can ask for yard watering and cutting hours. It is the same coordination seen in a building where the board negotiates with the contractor or in the common areas of a complex with works next door. To see how the rest of the district is handled, see what is checked in new Don Bosco homes.
Scheduling a review starts with a message to Climatiza, and the service page summarizes the process.

Frequently asked questions
Should I switch off the air conditioning when the neighbors cut tile?
There is no need to switch it off, but the windows on the works side should be closed during those hours. With windows closed the system recirculates house air and the filter does its job. With windows open, the return picks up incoming dust and spreads it.
Does a new house come with clean ducts?
Not always. Dust from its own construction can stay inside if the ducts were installed before finishing. That is why the reference camera photo at move in serves two purposes: knowing how it was delivered and comparing later with the neighboring works.
Does the prefilter layer over the return reduce the unit airflow?
Slightly, which is why light media is used and changed every two weeks. If the unit gets louder or cools less, the layer is loaded and needs changing. Thick media is not used and the main filter is not doubled.
When does cleaning make sense if the works will last a year?
At the end. During the works you protect and change filters. If at some point the grilles blow visible dust when the unit starts, the camera is brought forward to see how much got in, but cleaning waits until the outdoor dust stops.
