Chillers and Cooling Towers

Start with the system serving the affected area. A problem at a terminal unit may involve the chiller, circulation, controls or heat rejection. Replacing or servicing one component without reviewing the relevant interfaces can leave the original issue unresolved.

The work can include reviewing plant records, inspecting condition, investigating performance, carrying out defined servicing and developing repair or replacement packages. Chiller, pump, controls and heat-rejection tasks are identified separately where they form part of the instruction.

Deliverables describe the equipment assessed, operating conditions, work undertaken and further actions. Cooling-tower water treatment, cleaning, monitoring and risk-management responsibilities are explicitly allocated; they are not assumed to be covered by a mechanical service visit.

Plant type. A chiller can reject heat to air or to a water circuit. An evaporative tower uses water evaporation for heat rejection. Identify the actual arrangement and its connected systems.

Water risk. HSE's evaporative cooling guidance addresses legionella control, treatment, cleaning and monitoring. A routine service record does not replace the required risk assessment and control arrangements.

Capacity and condition. Review operating demand, flows, controls and condition before deciding whether a larger or replacement unit is needed. A loss of performance is a finding to investigate, not a capacity calculation.

Send the property address, equipment details, earlier reports and the symptoms prompting the enquiry. Ask the owner or existing operator for water-system records where a cooling tower is present; a tenant's air-conditioning service file may not contain them.

Confirm who owns the plant and who controls access. Explain how loss of cooling affects the property and which occupiers need notice. The first assessment clarifies the technical scope and any separate water-management responsibility.

We identify the equipment and responsible parties, agree the inspection or repair requirement and plan access around the property users. Work affecting refrigerant follows the applicable F-gas qualification requirements.

The owner receives an account of the work and the condition left, with separate actions for other specialists where needed. A completed mechanical repair does not silently close a water-risk finding or transfer responsibility for the cooling system.

The price depends on the equipment and the work needed to reach, assess and repair it. Roof access, shared plant rooms, missing records and specialist attendance can affect a property-level instruction before parts are ordered.

Clarify whether the proposal covers only a chiller task or also associated pumps, controls and water-system work. Agree affected occupier notices, access and handover, including any remaining restriction on use.

For managing agents, establish the shared-plant boundary and maintenance ownership. For hospitality premises, plant access and customer areas affect work timing. Property records should identify any evaporative system rather than use a general air-conditioning label.

The wider service and project range supports all sectors, including retail, FM companies, healthcare, veterinary premises, education, leisure, construction, public and community premises, transport, energy and utilities, residential blocks, social housing and secure estates. Scope follows the function and requirements of the actual property.

We cover Northumberland, Tyne and Wear, County Durham and the Tees Valley, including Berwick-upon-Tweed, Alnwick, Morpeth, Hexham, Newcastle, Gateshead, Sunderland, Durham, Darlington, Hartlepool, Stockton-on-Tees and Middlesbrough. See the full locations directory for the towns and surrounding areas.

Provide the full property address and access details, including any shared area or delivery restriction that affects the visit.

No. A chiller supplies cooling; a tower rejects heat. Some systems use both, while an air-cooled chiller has a different heat-rejection arrangement.

No. Servicing and the system's risk assessment and control scheme have different purposes. Their scopes and responsible people must remain identifiable.

Some checks can use normal operation; other work needs isolation or interrupted cooling. The assessment and programme identify the required conditions.

Obtain equipment details, ownership contacts, current service reports and any cooling-water risk records. Confirm who can authorise access, interruption and follow-up work.

Read what an HVAC maintenance contract should cover and what a legionella risk assessment involves. These explain separate parts of the management requirement.
