Do you know inefficient air conditioning systems can cost you more than you think? It can not just increase energy bills but also result in non-compliance fines. That’s why regular air conditioning inspections are a must. At K2 Heating and Cooling Solutions, we specialise in air conditioning inspections across the UK, helping businesses like yours stay compliant and energy-efficient.
We’re committed to helping you keep your air conditioning systems up to standard, so you avoid penalties or fines. Our accredited engineers carry out inspections in line with EPBD regulations and TM44 guidelines issued by the Chartered Institution of Building Services Engineers (CIBSE). As per current regulations, all AC systems with an output of more than 12kW must be inspected at least once every five years.
With every air conditioning inspection (ACI), our clients benefit from reduced carbon footprints and lower energy bills.
What is an Air Conditioning Inspection?
Under the Energy Performance of Buildings Directive (EPBD), an air conditioning inspection is mandatory for all systems rated over 12kW. The EPBD divides inspections into two categories: simple and complex, depending on the system’s size and configuration.
Scheduled inspections help identify areas for improvement, ensuring your air con system remains efficient and compliant. The process typically includes an on-site inspection followed by a detailed air conditioning inspection report that is valid for five years.
These inspections are not only a legal requirement but an opportunity to identify hidden inefficiencies that could be costing your home or business more than you realise.
Why is inspection of Air Conditioning Systems necessary?
An air conditioning inspection gives you valuable insights into your system’s energy efficiency. This allows homeowners, commercial building owners and facilities managers to explore opportunities to cut energy use, reduce emissions, and improve system performance.
When systems consume less energy, your carbon emissions are lowered, and so are your operational costs. It’s a win-win for both your organisation and the environment.
To ensure full compliance, only a certified energy assessor should carry out your inspection. Book your inspection with K2 air conditioning inspection company today to get ahead of any upcoming deadlines or audits.

Different types of air conditioning inspections offered by K2 Air Con Inspection Company
At K2, we’ve spent 16 years inspecting AC systems, giving us deep expertise in system efficiency, compliance, and industry standards.
We provide a comprehensive range of specialist inspections to help businesses stay compliant, improve system performance, and maintain a safe and efficient environment. Here are three key inspection services we offer: TM44, Legionella Risk Assessments, and F-Gas Inspections.
TM44 Air Conditioning Inspections
TM44 inspections are legally required for all air conditioning systems in the UK with a combined output over 12kW. These inspections, carried out every five years, are designed to assess the efficiency of your system and identify opportunities for energy savings. As accredited energy assessors, our team conducts thorough TM44 inspections and provides detailed reports that not only help you stay compliant with the Energy Performance of Buildings Directive (EPBD), but also reduce running costs and carbon emissions. We also provide guidance on optimising system performance based on our findings.
Legionella Risk Assessments
Legionella bacteria can pose complex health risks when water systems are not properly maintained, especially in commercial buildings with complex HVAC or plumbing setups. Under the Health and Safety at Work Act and the Approved Code of Practice (ACoP L8), business owners & landlords have a legal responsibility to assess & control the risk of Legionella. At K2, we carry out professional Legionella Risk Assessments in accordance with current UK legislation, ensuring your systems are safe and compliant. Our assessments include a full inspection of your water systems, finding potential risks, and a clear action plan for risk mitigation.
F-Gas Inspections
F-Gas inspections are crucial for businesses operating air conditioning systems containing fluorinated greenhouse gases. These checks are required under EU Regulation No 517/2014 to prevent refrigerant leaks, which can be harmful to the environment. Our certified engineers are trained to carry out F-Gas leak checks, system labelling, and proper record-keeping to ensure you meet your legal responsibilities. We also assist in minimising leakage and improving system longevity through proactive maintenance.
HVAC Inspections
A well-maintained HVAC system is key to ensuring indoor air quality, energy efficiency, and occupant comfort. At K2, we carry out detailed HVAC inspections to assess the performance and condition of your heating, ventilation, and air conditioning units. These inspections help identify potential faults, inefficiencies, and safety concerns before they escalate into costly issues. Whether you manage a commercial building, industrial facility, or public premises, our experienced engineers provide comprehensive reports with practical recommendations. Regular HVAC inspections not only support compliance with workplace health and safety regulations but also extend system lifespan and reduce operational costs.
What Do We Do In An Air Conditioning Inspection?
Our air conditioning energy assessment includes the following steps:
- Examining the air conditioning system to identify any signs of damage or reasons why the system might be underperforming.
- Thorough checks of all airflow systems, including filters, fans, and heat exchangers, to see if there are any blockages, dirt build-up, or other issues affecting efficiency.
- Assessment of system controls, like the location of sensors, operating schedules, and time settings, to ensure the system is running as it should.
- Reviewing documents and system records related to the air conditioning unit—such as when it was fitted and any previous maintenance work carried out.
- Generating a full air conditioning inspection report that covers everything from efficiency ratings, faults found, and suggestions for improvement, to control assessments, maintenance advice, and system sizing analysis.
- Providing a clear summary of our findings and tailored recommendations to help improve performance and efficiency.
We’d again reiterate that all these air conditioning energy assessments should only be performed by licensed professionals, like the team at K2 Heating and Cooling Solutions.
