Client: Cambridge Maintenance
Sector: Commercial Property Management
Project Focus: Chiller Replacement (Roof-Mounted System)
Location: The Chancery, Manchester

The brief
The ageing York chiller at The Chancery (installed approximately 20 years ago) was experiencing frequent faults, with no spare parts available. SK Heating & Cooling were tasked with surveying the system, calculating the required capacity, and proposing a replacement solution that would integrate with existing pipework.
The solution
Following detailed surveys and load assessments, SK Heating & Cooling selected a Daikin chiller and Dutypoint pump set to match the system requirements. After winning the competitive tender, SK managed a complex removal and installation process, including road closures and crane lifts.
The benefits
The client now benefits from a modern, efficient cooling system, reduced risk of breakdowns, increased ease of maintenance with readily available spare parts, improved building comfort, and a fully compliant installation, all completed within a short timeframe with minimal disruption to the surrounding area.
The business challenge
The original York chiller at The Chancery had been operating well beyond its intended service life. Frequent faults were becoming costly, and sourcing spare parts was no longer viable. Cambridge Maintenance needed a reliable replacement that would match the existing system’s load without requiring a full system redesign. Space constraints on the 7th floor rooftop and access challenges added complexity to the project delivery.
Our solution
SK Heating & Cooling carried out extensive system surveys and capacity calculations to ensure a like-for-like replacement could be achieved. A Daikin chiller was selected for its efficiency and compatibility, alongside a Dutypoint pump set for circulation.
Key works included:
- Isolation and draining of the existing chilled water system
- Replacement of a previously split frost coil within the AHU (and re-fitting in situ)
- Removal and safe disposal of the old York chiller, requiring dismantling into sections
- Careful planning of a crane lift operation, including road closures across three roads in a registered lifting plan
- Removal of the existing chiller unit and all ancillaries from the rooftop
- Installation of a new steel skid and new chiller within tight rooftop constraints
- Prefabrication and on-site assembly of new external pipework and DRV isolation valves
- System pressure testing, glycol dosing, and commissioning with Daikin engineer
All works were carefully phased and coordinated to minimise disruption to the client and surrounding area.

The outcome
Operational improvements
The building now benefits from significantly improved operational performance. With the new Daikin chiller in place, cooling is reliable and efficient, reducing the risk of system failures and providing a stable environment for occupants throughout the year.
Energy and cost savings
Energy and cost efficiency have also been improved. The modern chiller offers optimised energy use compared to the outdated York unit, helping to reduce the building’s ongoing running costs while also supporting sustainability targets.
Compliance and safety improvements
The project ensured full compliance with current F-Gas regulations and health and safety standards. By upgrading to a compliant system, Cambridge Maintenance can be confident that they are meeting all necessary legal and environmental responsibilities.
Staff and customer comfort
Staff, tenants, and visitors at The Chancery now enjoy enhanced comfort across the building, particularly during peak summer months, with improved temperature control and consistent cooling.
Future-proofed system
The upgraded system provides a future-proofed solution. With modern equipment, ease of maintenance, and a reliable service life ahead, the facilities management team have peace of mind that the cooling infrastructure will continue to perform well into the future.
The benefits
- Improved system reliability with modern chiller and pump set
- Increased energy efficiency and lower operational costs
- Full compliance with current building and environmental standards
- Successful management of complex crane operations with minimal disruption
- Future-proofed cooling system
- Enhanced staff and occupant comfort levels
