Maintenance contracts for buildings where downtime is an operational problem rather than an inconvenience: bank branch networks, hospitals, hotels, office towers, factories, malls and government buildings. Cycles are scoped against the building's actual load rather than a standard interval, and critical areas are serviced after office hours. Every job, visit and service record runs through our own job management system, so multi-site performance is measured and reportable per site or across a portfolio — which is what makes the difference between a vendor you trust and one you chase.

Larger commercial installations and replacements — VRV, chillers, AHU, cooling towers and mechanical ventilation. Building owners are welcome to come to us directly; we also submit competitively through tender and deliver as HVAC subcontractor to an appointed main contractor. Whichever route, the work is scheduled around a live building: occupancy patterns, access windows and disruption tolerance are part of the plan, not an afterthought at installation.

Design-and-build for offices, restaurants, clinics and premium homes — VRV/VRF and conventional systems. The work starts with heat load rather than floor area: how much heat the space actually generates, how it is zoned, where the outdoor units go, and how the system is controlled room by room. For fit-outs, the constraint that matters is usually the opening date, and the design work exists to protect it.

A bungalow is not a big apartment. Once a house has multiple floors, rooms used at different times of day, double-volume spaces and a west-facing elevation, the load is different in every room and it changes through the day — that is a design problem. The work starts with heat load per room, then zoning, then equipment: multi-zone VRV with independent control from consolidated outdoor plant, and concealed ductwork with grille positions resolved against the interior scheme. We work alongside your designer, renovator or architect, and homeowners come to us directly too.

Servicing, repair, chemical wash and new installation for homes across Selangor and Kuala Lumpur, including Seri Kembangan, Sri Petaling, Puchong, Petaling Jaya, Shah Alam, Subang Jaya, Cyberjaya and Putrajaya. As a Daikin authorised dealer we supply and install the same equipment we put into commercial buildings, and homeowners get the same technicians working to the same documented standards. A new system for a landed home, semi-D or bungalow goes to the design and installation team, because sizing a whole house is a design job.

A single technician can service one building well. Holding uniform quality across 126 branches is a different problem.
Chance Air-Cond Sales & Service Sdn. Bhd. is a system-driven HVAC contractor: documented SOPs, KPI monitoring, weekly management reviews, and squad-level accountability, all running on our own job management system. That structure is the actual product. Holding uniform quality across 126 bank branches, every cycle, with records to prove it, is an operational problem rather than a technical one — and it is the problem our operating model is built to solve.

Daikin authorised dealer

Eight years of commercial contracts
banking, healthcare, hospitality, F&B, and corporate office environments
Documented delivery
service records per site and per visit, tracked rather than asserted
The same operating model runs a 71-branch maintenance contract and a single home installation. What changes is scale, not method.
01
Scoped against your building
Maintenance cycles are set against the building's actual load rather than a standard interval. New systems start from heat load per room — how much heat the space generates — rather than floor area.
02
Scheduled around your operation
Critical, customer-facing areas are serviced after office hours; non-critical areas during normal hours, zone by zone. Occupancy patterns and access windows are part of the plan, not an afterthought at installation.
03
Executed to documented SOPs
Documented standard operating procedures, KPI monitoring, weekly management reviews and squad-level accountability — the same discipline whether it is one unit or a portfolio.
04
Recorded and reported
Every job, visit and service record runs through our own job management system: appointment, technician assignment, visit count, completion status and documentation per site.
On maintenance contracts: breakdowns responded to within 48 hours, preventive schedules held above 98% adherence.
Who we work for
Every client below operates something that cannot be switched off — a banking hall, a hospital corridor, a gaming floor, a dining room mid-service. That is the common thread, and it is the capability being bought: disciplined execution around live operations.

Commercial Maintenance
A nationwide bank's 71-branch Selangor network
Eight years. 71 branches. Renewed annually without interruption.
Previous contractors had delivered inconsistent quality across a large branch footprint and response times that did not match a customer-facing banking environment. CASS was appointed sole HVAC vendor for the Selangor zone — preventive maintenance, chemical cleaning, breakdown repair, system replacement and design advisory, with critical areas serviced after office hours and completion documented per branch.
Hotpot is the most demanding comfort environment in commercial F&B: every table is a live heat source, plus steam, plus a full kitchen behind. Systems were zoned by function rather than applied uniformly — higher-capacity cassettes over the burner load, independent control per VIP room, dedicated provision for kitchen and cold store. Four outlets delivered across Kuala Lumpur, Klang and Johor Bahru, including an outstation deployment.
Repeat tender awards in a 24-hour operating environment.
One property containing guest rooms, continuously-occupied gaming and public floors, conference spaces with variable occupancy, and outdoor-adjacent leisure facilities — none of which can be taken offline, each with a different load profile and access window. Repair and maintenance works are delivered job by job, won through competitive tender and scheduled around each area's operating requirements.

Highly recommend Chance Air-Cond Sales & Service to all. Jenny and her team, i.e. Nazrul and Hazril are attentive and very professional. They have provided excellent services from feedback to queries, providing quotation, checking the air-cond condition, advising the best approach for the air-cond service, performing thorough service of the air-cond, and lastly ensuring the service has been carried out properly without any further issues.

Professional and efficient, friendly service, kept my place clean and tidy, took a lot of precaution to make sure dust and debris don't get everywhere. Service is reasonably priced, even helped me fix a faulty aircon switch which I really appreciate at no additional cost. I'm saving this contact for the future!

Whether that's a branch network, a restaurant opening on a fixed date, a tender package, or one aircond in a bedroom that isn't cooling properly.
