The blower pushes air through filters, coil, plenum, branch ducts and room outlets. Restrict that path and the whole system struggles.
FixakitchenHVAC ducting and fabrication
Custom duct fabrication Cape Town
Custom ducting that fits the building.
We design and fabricate galvanized plenums, square duct, transition pieces and ducted AC routes around the real ceiling, walls, beams and service access on site. The goal is simple: move air properly, keep the system serviceable and avoid awkward ductwork that fights the building.
First, what can we help with?
What we can build, plan or fix
Send photos of the ceiling void, unit position and where the air needs to go. We can help with the duct route, sheet metal parts, diffuser boxes, air balance and the practical details before anything gets fabricated.

Built around the route
Ductwork should solve the room, not create a new problem
Ducting has to pass through real buildings: low ceilings, beams, hoods, lights, drains, wiring and awkward access panels. We plan the route first, then shape the plenums, branches and supports around that route so the system is easier to install, balance and maintain.

Air handler and return air
The ductwork is only as good as the air path feeding it
The indoor unit needs clean return air, filter access, a sensible plenum and branches that do not choke the blower. When the air handler and duct route are planned together, the system is quieter, easier to service and less likely to leave hot or cold spots.
Filters, coils, drains, sensors and panels need to be reachable. Hidden equipment becomes expensive the first time it needs cleaning or repair.
Branch sizes, damper positions and diffuser locations decide whether one room gets all the air while another room is left uncomfortable.
Weak airflow, noisy grilles, water leaks, dirty filters and uneven temperatures usually point back to access, airflow or duct balance.
01
Custom sheet metal parts
Galvanized sheet metal parts made for the job: plenums, square duct, reducers, offsets, take-offs and sections that can be opened or serviced later.

Ducted AC installation support
Support for ducted AC routes in homes, restaurants, offices and open commercial spaces, including brackets, supports, condensate paths, duct sealing and air-balance checks.
- Ducted AC system installation
- Open-plan commercial cooling layouts
- Structural supports and precise duct routing
03
Maintenance and airflow improvement
Existing systems can often be improved with coil cleaning, filter changes, damper adjustment, duct sealing, airflow checks and better access to the parts that need regular service.
- Commercial air conditioning maintenance Western Cape
- Static pressure balancing and duct sealing
- Server room cooling and maintenance
Sheet metal fabrication
Sheet metal parts made for awkward spaces.
The best duct section is the one that fits the route, seals properly and can still be reached later. We shape the metal around the ceiling, equipment and access points instead of forcing a generic part into place.
- Galvanized plenum boxes, reducers, offsets and take-offs
- Diffuser boxes and access panels sized around ceiling voids
- Fabrication detail that keeps future maintenance practical
Ducted AC layout
Supply and return air planned together.
Cold air going out is only half the story. The system also needs a clean return path back to the indoor unit, plus filter and coil access for future servicing.
- Indoor unit position, branch routes and diffuser locations
- Return-air planning, filter access and condensate route checks
- Balancing dampers and airflow checks for quieter performance
Installation support
Kitchen ceilings need careful coordination.
Commercial kitchen ceilings get crowded quickly. AC ducting, extraction, make-up air, lighting, drainage and electrical work all need their own space. Planning the route early keeps the ceiling build cleaner.
- Support points, ceiling void routing and service clearance
- Coordination with hood extraction and make-up air planning
- Commissioning support for airflow, noise and access issues
Correct sign-off route
We keep mechanical work and regulated refrigeration work in the right lanes
Fixakitchen can manage the ducting, sheet metal, supports, access and site coordination. Where the job includes regulated refrigeration commissioning or a Certificate of Conformity, the correct authorised refrigeration practitioner is brought in for that scope.
Mechanical scopeDuct design, fabrication, supports, routing and access planned as one project.
Refrigeration scopeAuthorised practitioners are used where refrigerant-side commissioning requires it.
CoC routeCertificates are issued by the practitioner responsible for the regulated work.

Send the ceiling, the unit and the route
For a useful ducting quote, send the room size, ceiling photos, unit position, where the air must go and anything already installed in the ceiling. Clear photos make it much easier to plan the sheet metal, access and installation time.

ComplianceRequired cooling capacity, refrigerant type if known and whether a CoC or commercial sign-off is needed.
