What is TM44 Air Conditioning Inspection?

TM44 inspection, or survey, is an assessment of a building's air conditioning systems. Their primary purpose was to help businesses improve the efficiency of their buildings. More specifically, reducing energy consumption, carbon emissions and operating costs. All typical issues associated with air conditioning.

How much does a TM44 inspection cost?

A TM44 does vary quite significantly in price as no two sites are ever the same. System type, number of units and building size all differ from site to site. This makes it difficult to set a standard fee for TM44. Additionally, TM44 inspections have two different levels. The level you require depends on the air conditioning equipment you have on site. Your building will need a level 4 assessment if your building has air handling units or centralized chillers. The fee for a level 4 inspection will be higher than a level 3.

This is because the assessor will need to inspect more equipment and take longer on site. Furthermore, the report will take longer to write up as there is more content. If you are unsure which level you need we can advise what is required for your property. The easiest way to calculate the cost of a TM44 survey is to contact one of our expert commercial compliance teams. They will be able to provide you with a free quotation and answer any questions that you might have.
