Delivering in live banking, healthcare and hospitality environments since 2018 · Tendered works at a major integrated resort · Daikin Million Dollar Dealer, 6 consecutive years · Daikin VRV CORE dealer
Plant that carries a building.
VRV, ducted and cassette systems across whole floors, delivered while the building stays open.
Who This Is For
Building owners with a project
We prefer working with you directly.Direct engagement means the design intent doesn’t get diluted through layers, scoping is transparent, and there’s one party accountable for the outcome. If you own or manage a building with a commercial HVAC requirement — a system replacement, a VRV installation, a plant upgrade — talk to us first.
Main contractors and developers
We work as the HVAC subcontractor on commercial projects, delivering to programme with the documentation your project requires.
Mechanical consultants and quantity surveyors
We submit to specification, participate in tender, and provide the technical documentation and pricing breakdowns your process needs.
Project Scope
VRV / VRF systems
Multi-zone commercial installations — offices, retail, hospitality, institutional buildings.
Commercial ACMV
Air conditioning and mechanical ventilation delivered as an integrated scope rather than separate trades.
Chiller systems
Where a project includes chillers or central plant, we carry that scope as part of the package and bring in a specialist subcontractor to execute it — CASS holds the contract, the coordination and the programme. We are not a chiller plant specialist and do not present as one.
AHU — air handling units
Installation, replacement, servicing, and plant room works.
Cooling towers
Servicing and maintenance of cooling tower systems.
Mechanical ventilation
Fresh air, exhaust, and pressure balance for commercial and industrial premises.
Industrial HVAC
Factory and industrial premises — high-load environments, process-adjacent cooling, and ventilation.
System replacement and upgrades
End-of-life replacement, capacity upgrades, and efficiency retrofits — with design input where a like-for-like swap isn’t the right answer.
Multi-site delivery at volume
Mobilising crews across dozens of sites to a single standard is its own capability, separate from any one installation — CASS has fitted over 1,500 homes across 22+ developments since 2018, and maintains 126 bank branches across two nationwide networks today.
How We Engage
Owner-direct
Our preferred route. You get design input from the start, transparent scoping, and a single point of accountability. No margin stacking through intermediaries, and no confusion about who owns the outcome.
Most of our commercial project work now arrives this way — owners who’ve seen the system elsewhere, or who want the work done by the contractor who’ll also maintain it afterwards.
Tender
Where work goes to tender, we submit competitively with full technical documentation, specification compliance, and pricing breakdowns. We deliver repeat tendered works at one of Malaysia’s largest integrated resort properties, where every job is won on competitive submission.
As subcontractor
For main contractors and developers, we deliver the HVAC scope to programme with the documentation and coordination the project requires.
Delivering in Live Environments
Every institutional client we serve runs an environment that cannot be shut down.
A bank hall. A hospital corridor. A gaming floor. A hotel guest room. Each has different occupancy patterns, access windows, and tolerance for disruption — and none of them can go offline while work happens.
That constraint shapes everything: how work is sequenced, when crews attend, how areas are isolated, and how completion is documented. It’s the difference between a contractor who can quote a project and one who can deliver it inside a working building.
Where we’ve done it:
- Banking — 126 branches across two nationwide networks, serviced around banking hours since 2018
- Healthcare — private hospitals in the Klang Valley, after-hours work in continuously operating facilities
- Hospitality and leisure — a major integrated resort: hotel rooms, gaming floors, conference facilities, theme park areas, delivered job-by-job through competitive tender in a 24-hour operating environment
Engineering, not a catalogue
Riser routing, plant placement, ventilation and the finished room — what a commercial fit-out is actually judged on.
Ventilation is the half of ACMV that decides whether a ceiling closes on programme. Trunking, flexible runs, pipework and cable all compete for the same void, and the order they go in is settled long before anyone is on site. 
Outdoor plant carried on a rear elevation across several storeys, where no roof deck was available. 
Refrigerant risers clipped and insulated floor to ceiling. Routing decided at design stage is what keeps a shaft serviceable ten years later. 
Every diffuser connection is a balancing point. Get the take-off wrong and the room nearest the plant is loud while the room at the end of the run never reaches setpoint. 
The condition the client actually sees: a finished dining room with the system set into the ceiling.
Proof
Major Integrated Resort — Tendered Works Across Four Environment Types
A major integrated resort and leisure destination presents an unusually wide range of HVAC environments within one property: guest rooms with individual comfort requirements, large continuously occupied public floors, conference spaces with variable occupancy loads, and outdoor-adjacent leisure facilities. Nothing can be taken offline — the property runs around the clock.
CASS delivers repair and maintenance works across all of these environments on a per-job competitive tender basis, scheduling each engagement around the specific operating requirements of the area concerned.
Repeat tender awards. Four distinct environment types. One 24-hour property.
Banking Networks — 126 Branches, Two Institutions
Sole HVAC vendor to a leading Malaysian bank’s 71-branch Selangor network since 2018, and to a second nationwide bank’s 55-branch peninsula network since 2025. Full-scope delivery including system replacement, design advisory, and after-hours execution in customer-facing environments.
Healthcare — Klang Valley Private Hospitals
System replacement and reconfiguration work at private hospitals since 2023, executed after hours in continuously operating healthcare facilities.
Why Owners Come Direct
We spent years building in a segment the large players overlooked — multi-site institutional maintenance, delivered with documentation and consistency. That work produced something useful: a track record in exactly the environments where project risk is highest.
Owners who come to us directly are usually looking for one of three things:
- A contractor who will also maintain the system afterwards — so the design accounts for serviceability, not just installation day
- Transparent scoping— knowing what’s included and why, without layers of intermediary margin
- Proven delivery in a live building — evidence that the work can happen without shutting operations down

Frequently Asked Questions
What do you need to quote a commercial project?+−
Building type and use, system type and scale, drawings or specifications if available, site access constraints, and your timeline. If it's a replacement, the existing system details help. Send what you have on WhatsApp.
Do you work owner-direct or only through main contractors?+−
Both, and we prefer owner-direct. Direct engagement means transparent scoping and a single point of accountability. We also work as HVAC subcontractor to main contractors and developers.
Do you participate in tender?+−
Yes — with full technical documentation, specification compliance, and pricing breakdowns. We currently deliver repeat tendered works at a major integrated resort property.
What's included in an ACMV scope?+−
Air conditioning and mechanical ventilation as one integrated scope — cooling systems, fresh air, exhaust, and pressure balance. Treating them separately is where most commercial HVAC problems originate.
Do you service chillers, AHU, and cooling towers?+−
Yes — chiller servicing and maintenance, AHU installation and plant room works, and cooling tower servicing, alongside VRV/VRF and split systems.
Can you work in a building that stays operational?+−
Yes. Every institutional client we serve operates continuously — banking, healthcare, and hospitality. Work is sequenced around occupancy patterns and access windows, with completion documented per area.
Do you handle industrial and factory premises?+−
Yes — high-load industrial environments, process-adjacent cooling, and mechanical ventilation for factory premises.
What documentation do you provide?+−
Technical submissions and specification compliance for tender, service and completion documentation for delivered works, and design documentation where we've provided design input.
