Air Conditioning systems (used for providing human comfort) larger than 12kW output are subject to mandatory 5 yearly inspections as from

     systems in excess of 250kW output (level 4 systems) : 4 January 2009

     systems between 12kW and 250kW output (level 3 systems) : 4 January 2011

Systems which are used exclusively for industrial processes are exempt from the requirements.

For information on the government website relating to Air Conditioning Inspections, follow the link.

These dates are not when the requirement commences, but when the first inspection should be complete and records in place by.

Additionally, where a property is sold or let, there is a requirement for an inspection to be commissioned within 3 months of the change of responsible person.

Whilst the situation with larger systems is quite clear, smaller systems can present differing scenarios regarding being within or outside the requirements.

For instance: A building is owned by a landlord, who has a number of tenants. Each separate tenanted area has a self contained small split air conditioner of 6kW output. The landlord had the a/c systems installed, and is the responsible person for maintenance etc.

All these units would be subject to the requirements of an inspection. The trigger is the fact that one person/entity is responsible for the whole output.

The requirements are not limited to commercial properties, the landlord of a block of residential flats with heat pumps would also be subject to the regulations.

APP Inspections & Energy Services are qualified to level 4, and can
carry out inspections on all systems.

APPI provide Air Conditioning Inspections to all commercial, public and residential buildings. We service all the major towns and cities of central Yorkshire and Lancashire (and anywhere inbetween) for  commercial EPCs and DECs (Barnsley, Blackburn, Bolton, Bradford, Burnley, Bury, Castleford, Clitheroe, Dewsbury, Doncaster, Halifax, Harrogate, Huddersfield, Leeds, Manchester, Oldham, Pontefract, Ripon, Skipton, Wakefield, Wetherby, York). We also cover Cheshire, Cumbria, Derbyshire, Greater Manchester, North Lincs, North Notts, Tyne & Wear.

All inspections include an advisory report to enable energy efficiency improvements to be considered. In many instances with older installations, this will pick up that the refrigerant is obsolete, and indeed may be a banned substance, as earlier refrigerants were particularly detrimental to the ozone layer. There are numerous replacement refrigerants available as "drop in" replacements.
Other recommendations likely include regular maintenance and upgrading of specific components.

Air conditioning/heat pump technology has advanced substantially in the last 5 years, resulting in systems and components that operate at a fraction of the energy consumption of their earlier counterparts. Many recommendations, if put into practise, can pay for themselves in a relatively short space of time due to reduced energy consumption. Occasionally, the wholesale replacement of a system can be justified purely on energy savings, more typically replacement becomes advantageous when the breakdown/maintenance performance of older systems is factored in.
