Apartment: own ducts and building ducts, who pays for what
In a condominium nearly everything hanging from the apartment ceiling belongs to the owner, but not everything. Knowing where the boundary lies avoids arguments with the administration.
By 
It depends on whom the duct serves. What serves only the apartment, such as the unit, the home ducts, the grilles and the filter, is paid by the owner. What serves several units, such as a central duct or the air in corridors and lobby, is covered by the condominium out of the budget the assembly approves. Each building’s bylaws refine the boundary, and the camera helps locate it.
An owner of an apartment in a tower notices that the living room air has smelled odd for weeks. She writes to the administration to have “the building ducts” checked and gets a polite reply: the ducts in her unit are hers. She insists the smell comes in through a grille next to the corridor wall. Neither side has the plan at hand, and the conversation stalls over who pays.
That kind of stall is avoidable. Most buildings with apartments have a fairly clear boundary between what is private and what is common, it is just that almost nobody has drawn it on paper. Drawing it takes an afternoon and saves months of emails.
What belongs to the owner and what to the condominium?
The practical rule is that each asset is maintained by whoever owns it. Law 284 of 2022 on horizontal property starts from that principle when it speaks of the upkeep of private and common property, and assigns ordinary tasks to the administrator with the budget approved by the assembly. In the text reviewed no express mention of ducts or air conditioning was found, so the boundary comes from applying the general principle and from whatever each building’s bylaws say.
The fieldwork is carried out by the Climatiza team, who check branches, grilles and air handlers and record the result in an illustrated report, also in the case of apartments.
| Element | Who covers it |
|---|---|
| The apartment’s unit, air handler or console | Owner |
| Ducts, grilles and filter inside the home | Owner |
| Central duct or riser running through several floors | Condominium, with the assembly’s budget |
| Air in corridors, lobby, gym and social hall | Condominium, with the assembly’s budget |
| Rooftop outdoor unit serving a single apartment | Owner, with access authorized by the administration |
How can anyone tell where the apartment’s own system ends?
In most towers each apartment has its own unit, and the administration does not step inside the home. The exceptions are buildings with central chilled water, where the plant is common but each apartment’s air handler is private, and older buildings with a fresh air or exhaust duct running through every floor. In those cases the boundary sits at the point where the common duct enters the home.
Three documents and one look help to locate it. The documents are the co-ownership bylaws, the mechanical plan if the administration keeps it and the apartment’s handover record. The look is a camera inspection from the grilles of the home, which follows the duct to the point where it joins something that is no longer part of the apartment. If the camera never leaves the home, the whole run is private and the discussion ends there.
An illustrative case, not a real client: in a tower with central chilled water, an owner asks for an inspection because of the smell in the living room. The camera enters through the grille, runs along two branches of the home and reaches the air handler box, all inside the apartment, with a saturated filter and a pan holding residue. The odor had its own cause and there was nothing to claim from the building. With the images in hand, the owner knows what to fix and does not lose weeks waiting for an answer from the administration.
Why does it matter to make the boundary clear?
Because without a boundary nobody looks. The owner assumes the common duct belongs to the administration, the administration assumes anything hanging from an apartment is private, and the stretch in between goes without maintenance for years. That turns into odors nobody can explain, grilles that drip with no owner and the feeling that the building is responsible for everything and nothing.
It also matters for selling or renting. A careful buyer asks about the air conditioning before the paint, and an answer backed by papers conveys order. And it matters for the apartment that sits closed for months: the private unit is switched off while the shared system keeps working for the neighbors, so the absent owner returns to a musty smell that is their own, and it helps if someone with a key switches the unit on now and then and looks at the pan.
How is a case put to the administration?
When the problem seems to come from outside the home, the owner raises it in writing and with facts, not as a general complaint. The administration acts with the approved budget and, if the expense was not planned, takes it to the board. A well put together request shortens that path.
The request works best with four elements. First, the symptom described precisely: what is noticed, in which room, at what time and since when, with a photo if there is a stain on the grille. Second, what was already checked, such as the replaced filter, the cleaned pan and the camera images from inside the home. Third, the doubtful section, pointing out the grille or duct believed to be common and asking the administration to confirm whom it belongs to. And fourth, access, setting a date if the common review requires entering the home and keeping a record of what was reviewed.
Which report is worth keeping?
The one for the private part is worth keeping: camera images of the home’s ducts, a photo of the filter and the pan, the date and a line saying whether it was cleaned or only checked. If a common duct exists, the administration’s written statement on its last review is attached. The report speaks of condition and dates, not benefits, because the EPA reminds that cleaning has not been shown to prevent health problems.
That document is kept with the equipment invoices and handed over with the keys. The criteria for knowing when a duct needs cleaning avoid cleaning out of habit before selling. How a board decides on common areas is summarized in the page on condominium buildings, and the other kinds of places the service covers show similar boundaries in other buildings.
For a first conversation about the system, the contact details are on the Climatiza site and the method is described on its duct cleaning service page.

Why does inspecting and cleaning ducts matter?
These are the technical reasons, with their source, why the condition of the ducts is checked before deciding. Duct cleaning has not been shown to prevent health problems according to the EPA and the CDC, and it is proposed only when the observed condition justifies it.
| Advantage | Data with source | What it means in practice |
|---|---|---|
| Anticipate the tropical humidity | According to ETESA (Tocumen station, 1977 to 2010), mean annual relative humidity in Panama is 75.7 % and rises to between 78.2 and 82.4 % in the rainy months. | The condensate pan, the drain and the coil are checked first, because that is where moisture builds up. |
| Protect equipment performance | In a laboratory test with dust equivalent to one year of use, coil pressure drop rose between 6 and 30 % and efficiency (EER) fell between 1 and 9 % (Yang, Braun and Groll, ARTI, 2004). | It is a laboratory result and not a promise of savings: it points to the components worth checking. |
| Follow a technical inspection reference | The ANSI/ASHRAE/ACCA 180 standard is the standard practice for inspection and maintenance of commercial HVAC systems. | It is an industry reference, not a legal requirement in Panama, and helps organize the review plan. |
| Keep construction dust out of the system | The EPA and NIOSH Building Air Quality guide asks to block return grilles while construction work takes place in occupied buildings. | Before accepting a new or remodeled system it is worth checking whether construction dust got in. |
| A local figure that changes the decision | Law 284 of 2022 on horizontal property sets as a principle ensuring the maintenance, salubrity, safety and conservation of private and common property. The administrator carries out ordinary administration and conservation work with the budget approved by the Assembly. The law does not expressly mention ducts or air conditioning and its regulation is still pending. (Official Gazette 29476-C, Law 284 of 2022). | It is the sector context taken into account when planning the visit. |
Frequently asked questions
Does the administration clean the ducts that pass through my ceiling?
Only if they are common ducts, such as a riser serving several floors. Ducts that serve only the apartment belong to the owner. When in doubt, the administration is asked to confirm in writing who owns the section.
What if the smell comes in from the corridor?
It is raised with the administration with date, place and photo. Corridor and lobby air is common. The camera from the home’s grilles makes it possible to check whether the smell comes from a private section or a shared one.
Is a duct report useful when selling the apartment?
Yes, if it shows the actual condition with a date and photos and says whether it was cleaned or only checked. It gives order to the equipment file and spares the buyer from asking about something already documented.
What does Law 284 of 2022 say about maintaining private and common property in a condominium?
Its guiding principle is to ensure the maintenance, sanitation, safety, and upkeep of private and common property, and article 93 entrusts the administrator with ordinary upkeep tasks using the budget approved by the assembly. The text consulted contained no mention of ducts or air conditioning.
Who maintains the outdoor unit on the roof that serves a single apartment?
Its owner, even though it sits on a common space. As a general criterion, each asset is maintained by whoever owns it, and access is authorized by the condominium administration. What serves several apartments, such as a central duct, is common property and comes out of the budget the assembly approves.
