TM44 Air Conditioning & Inspections


A TM44 Air Conditioning Inspection is required for buildings where air conditioning systems have a combined total cooling capacity greater than 12kW and these inspections must be carried out every 5 years by an accredited air conditioning energy assessor.

Only reports that have been produced and lodged by an accredited air conditioning assessor are valid reports and there are two types of inspections that can be offered depending on the type of air conditioning systems installed in your building.

  • Level 3 inspection focuses on simple systems such as packaged split systems installed in a naturally ventilated building.

  • Level 4 inspection is required for buildings that contain more complex systems such as mechanically ventilated buildings.


All of our air conditioning energy assessors are fully accredited with many able to deliver both level 3 and level 4 assessments and we offer nationwide coverage as required.

The benefit of air conditioning inspections


The Inspection is designed to improve the efficiency, energy consumption, operating costs and carbon emissions of the air conditioning systems installed in your building.

Low cost or no cost inspections


Although there is no legal requirement for you to act on the recommendations made on our report, many of the saving opportunities we will identify will be low cost or no cost changes, which can be implemented quickly and inexpensively and the savings made will often cover the cost of your inspection.

Your air conditioning inspection report will include the following information:

  • Executive summary and key recommendations.

  • The efficiency of the system and suggestions for improvement.

  • Any faults identified during the inspection and suggested actions.

  • The adequacy of equipment maintenance and any suggestions for improvement.

  • The adequacy of the installed controls and control settings and any suggestions made for improvement.

  • The size of the installed system in relation to the cooling loads and any suggestions for improvement.
