Building owners and managers who control air-conditioning systems have statutory obligations and duties of care in the operation and maintenance of air-conditioning systems.

Having your air-conditioning system inspected by an Energy Assessor is designed to improve efficiency and reduce the electricity consumption, operating costs and carbon emissions for your system. Inspection, maintenance and cleaning programmes maintain the ability of the system to provide healthy and comfortable environments for building occupants, limiting the escape of refrigerant gases and ensuring the safety of equipment.

Systems requiring an air-conditioning inspection

All air-conditioning systems with an effective rated output of more than 12kw must be regularly inspected by an Energy Assessor. The inspections must be no more than five years apart.

For all systems from 2008 onwards the first inspection must have taken place within five years.

Systems installed before 2008

    • where the effective rated output is more than 250kW the first inspection must have happened by 4 January 2009
    • where the effective rated output is more than 12kW the first inspection must have happened by 4 January 2011

From 4 January 2011, if the person in control of the air-conditioning system changes and the new person in control is not given an inspection report, the new person in control of the system must ensure the air-conditioning system is inspected within three months of the day that person assumes control of the system.

What a report must contain

The inspection report must include an assessment of the efficiency of the system and its size compared to the cooling requirements of the building. It must also contain appropriate advice on possible improvements to the system.

The following information must be included:

    • the address of the building in which the system is located
    • the name of the energy assessor
    • the name and address of the energy assessor’s employer, or the name under which the assessor trades and his address
    • the date on which the inspection occurred
    • the name of the approved accreditation scheme that he is a member of

Energy Assessor accreditation

An air-conditioning inspection can only be performed by a Government approved Energy Assessor. Accreditation schemes control the quality of air-conditioning inspections by ensuring energy assessors are competent and possess the appropriate skills to conduct energy assessments.
