Air conditioning energy assessment

TM44 A/C Inspections

O.M Energy Assessments are independent accredited energy assessors and leading providers of TM44 Air Conditioning Inspections. We are also F-Gas registered air conditioning engineers with nearly 15 years experience in the HVAC industry. 


A TM44 is a legal requirement where a single air conditioning system or multiple systems are installed in a building with a combined rated output of 12kW or more.  

A TM44 is a great way to highlight any air conditioning system inefficiencies and provides recommendations to reduce energy usage and running costs. 

Whether you manage a single site or multiple sites we are able to provide you with cost effective TM44 Air Conditioning Inspections, ensuring you remain compliant and helping you save money on your energy bill.

Providing a valid TM44 certificate is not only a legal requirement but also an essential part of ISO 14001 and ISO 18001 audits. Non compliance can lead to audit failures and recurring £300 fines. Ensure you are compliant and contact us today for advice and a free estimate.
