TM44 Air Conditioning Inspections Explained

TM44 Air Conditioning Inspections Explained

TM44 Air Conditioning legislation aims to assess and improve the energy efficiency of public and commercial properties.

Air Conditioning Inspections (TM44) were first introduced in 2007 under the Energy Performance of Buildings Regulations.

Requirements of an inspection include the inspection being conducted by an accredited assessor and each inspection must not be more than 5 years apart.

Does my system require an inspection?

If your system has an effective rated output of more than 12Kw it is required to be inspected and have a valid TM44 report. Systems that consist of individual units which are less than 12kW, but whose overall combined effective rated output is more than 12kW require an inspection.

Whose responsibility is it?

It is the building owners or facilities manager’s responsibility to ensure that valid TM44 inspections are in place. Building owners and facilities managers have a statutory obligation and duty of care, in the operation and maintenance of each air conditioning system within their responsibility. They also must keep a copy of the report, and be able to provide the report to any future operators of the system. If the new operator does not have a copy of the report, the system must be inspected within 3 months of the new operator taking over the system.

What are the benefits of a TM44 inspection?

Having a TM44 inspection carried out can help you avoid fines. If your system is not inspected every 5 years, the building owner or facilities manager can face a fine of £300 per air conditioning unit.

Other benefits of having a TM44 inspection include:

  • Potentially seeing a reduction in operating costs.
  • The report may identify any faults within the system.
  • You will receive information about how energy efficient your system is.
