Regular maintenance of any air conditioning or ventilation equipment is vital to ensuring its efficiency, longevity and cleanliness. For some equipment it is also a necessity to have systems checked in accordance with legal regulations (F Gas Certification).
Regular HVACR maintenance is said to reduce the risk of costly breakdowns by as much as 95%. Chances are you wouldn’t drive your car for 30,000 miles without getting an oil change; you’d be asking for trouble.
Regular maintenance of HVACR equipment helps to ensure that the system is running at peak efficiency, reducing energy consumption, and lowering energy bills.
Regular maintenance gives your equipment a much longer life expectancy potentially by many years and delays the need for replacement systems.
Should you have a breakdown during the manufacturer’s warranty period, it would be expected that a replacement part or equipment would be provided, however should the system not have received regular maintenance manufacturers can potentially void the warranty. Manufacturers also require proof of annual maintenance when a repair claim is submitted under warranty.
HVACR equipment plays a crucial role in maintaining indoor air quality. Dirty or clogged filters, coils, and ductwork can lead to poor air quality, potentially causing health problems such as allergies, asthma, and respiratory infections. Regular maintenance can help prevent these issues and ensure that the air inside your building is clean and healthy.
Correctly maintaining HVACR system helps to ensure that the temperature and humidity levels in your office or building, are consistent and comfortable. This is especially important in commercial settings, where employee productivity and customer satisfaction can be affected by the indoor environment.
Maintaining HVACR systems can help reduce energy consumption, greenhouse gas emissions, and the environmental impact of refrigerants. Our maintenance engineers can also talk to you about the benefits of using a programmable thermostat or setting timers and controls so you can help reduce your system’s impact on the environment.
Faulty or poorly maintained HVACR equipment can be a safety hazard. Equipment that is left unmaintained can potentially be a fire risk, pose a risk to the environment and building occupants and potentially be deadly if not inspected for poor fitting or wear and tear.
The legal requirements for maintaining HVACR systems include regular inspections under the Energy Performance of Buildings Regulations, leak testing and repair under the F-gas Regulations, maintaining and cleaning the system regularly under the Workplace (Health, Safety and Welfare) Regulations, and preventing exposure to hazardous substances under the COSHH Regulations. It is essential to comply with these regulations to ensure the safe and efficient operation of systems as well as avoid any legal implications.
A lack of maintenance may potentially affect an insurance claim if the cause of the damage or loss is related to a HVACR system. Insurance companies may require proof of regular maintenance as a condition for processing the claim.
It is essential to keep records of equipment maintenance, including service reports and invoices, as they may be required to support an insurance claim.
Investing in a regular preventive maintenance plan gives you peace of mind; knowing that you have done everything you can to mitigate risks, be compliant and prevent unnecessary costs is a good position to be in.
There are several signs that can indicate that your equipment needs servicing. Here are some common ones:
Reduced Cooling or Heating Performance: If your system is not providing sufficient cooling or heating, it may be a sign that it needs servicing. This could be due to clogged filters, low refrigerant levels, or other issues that can be resolved through servicing.
Noises or Odours: If you notice unusual noises or odours, it may indicate a problem. For example, a grinding or squealing noise could mean that the system’s fan or motor is malfunctioning, and a musty odour could indicate mould growth in the unit.
Higher Energy Bills: If you notice a sudden increase in your energy bills without any apparent reason, it could be due to an inefficient system that needs servicing. Dirty filters, clogged condenser coils, or other issues can cause the system to work harder than necessary, leading to higher energy consumption.
Poor Airflow: If the air coming out of your system is weak or not flowing correctly, it could be due to blocked or damaged ductwork, clogged filters, or other issues that can be resolved through servicing.
Water Leak: If you notice moisture or a water leak around your system, it could indicate a clogged drain line that needs to be cleaned or a failed condensate pump.
Should you notice any of these signs, it is important to contact SFE Services as soon as possible to repair the problem and carry out a full service of the system. In our experience faults which are left unchecked often go on to cause larger costly repairs, all of which can be avoided with regular preventative maintenance.
The frequency of air conditioning or ventilation servicing depends on various factors, including the type of units, usage, environment, and manufacturer’s recommendations.
We would advise clients with systems installed in a residential property to have these serviced once per year, however this is dependent on usage; with many home owners now opting to use air conditioning to provide cooling and heating all year round it may be advisable to have this maintained twice per year.
Systems fitted in commercial settings can vary considerably for how often they require servicing, as the environment in which they are installed can drastically impact the systems filters, drains and mechanical components. As a general rule offices, shops, restaurants and light commercial buildings would require equipment servicing twice per year, whereas sterile environments such as hospitals, dentists and laboratories or highly critical temperature sensitive environments such as data centres could be quarterly.
At SFE Services we do not operate a “one size fits all” maintenance package and tailor all our servicing programmes to suit individual clients. Please see our “What You Need to Know” section for more information about what a service visit involves and our price guide.
Most commercial properties will have a network of ductwork in ceilings, walls or exposed, it is important to ensure these systems are cleaned and maintained correctly.
Ductwork plays a crucial role in heating, ventilation, and air conditioning (HVAC) systems. It is responsible for distributing air throughout a building and maintaining indoor air quality. However, over time, ductwork can become contaminated with dust, dirt, pollen, mould, and other harmful particles, which can affect the efficiency and performance of the system and pose health risks to occupants.
Here are some reasons why you need to have ductwork cleaned:
Improved Indoor Air Quality: Duct cleaning removes dust, dirt, and other contaminants that can affect indoor air quality, which can be particularly important for those with allergies or respiratory issues. Unhygienic ducts have been proven to be one of the main causes of Sick Building Syndrome, a situation where all of the staff continuously suffer from minor illnesses such as viruses, flu and colds as well as allergies. In clinical environments such as hospitals the potential effects can be even worse with MRSA and other infections taking hold as a result. Cleaner air can help prevent health issues and promote a healthier living / working environments.
Increased Efficiency: Dirty ductwork can restrict airflow and cause the HVAC system to work harder to maintain desired temperatures, resulting in increased energy consumption and higher utility bills. Clean ductwork can improve airflow, reduce strain on the system, and improve its overall efficiency.
Extended System Lifespan: Contaminants in the ductwork can cause the HVAC system to wear out faster, resulting in premature failure and costly repairs. Regular duct cleaning can help extend the lifespan of the HVAC system and reduce the risk of breakdowns and repairs.
Removal of Unpleasant Odours: If you notice unpleasant odours coming from your HVAC system, it may be a sign that contaminants are present in the ductwork. Duct cleaning can remove these contaminants and eliminate the source of the odour.
Compliance with Building Regulations: Building regulations require regular duct cleaning to maintain indoor air quality standards and prevent health risks. It is important to check with your local authorities and building regulations to determine the specific requirements for your building. Insurance companies are also becoming increasingly interested in how employers maintain their buildings and equipment. In the event of an employee claim or fire, insurers will ask for evidence of suitable and effective maintenance. If this is not available, then claims could be rejected.
We recommend all HVAC systems and extractors should be inspected for cleanliness each year.
In terms of cleaning, we would suggest you clean your air ducts every 2-3 years. This will ensure fresh air is being passed through the building rather than dust, mould and bacteria.

A TM44 inspection is an assessment of the efficiency of air conditioning systems in commercial buildings. A property which has an air conditioning system with over a 12kW capacity, by law, must have a TM44 regulations inspection every 5 years.
The primary objective of a TM44 inspection is to identify ways to improve the efficiency of air conditioning systems, reduce energy consumption, and minimize environmental impact. The inspection report will include recommendations for improving the system’s energy performance, reducing energy consumption, and minimizing the environmental impact, such as upgrading or replacing equipment, optimizing settings, improving maintenance procedures, or implementing energy-saving measures.
The TM44 inspection is conducted by a qualified and accredited energy assessor who will perform a comprehensive review of the air conditioning system’s performance and energy efficiency. The inspection includes an examination of the system’s design, installation, operation, and maintenance, as well as an analysis of energy consumption and potential energy-saving measures.
The typical steps involved in an inspection are:
Initial assessment: The inspector will review any available documentation about the building’s air conditioning system, such as plans, maintenance records, and previous inspection reports. They may also ask questions to understand the system’s usage and any issues that have been observed.
Visual inspection: The inspector will conduct a visual inspection of the air conditioning system, looking for any signs of damage, wear and tear, or poor maintenance. They may also assess the layout of the system and check for any potential hazards.
Performance testing: The inspector will conduct various tests on the air conditioning system to assess its efficiency and compliance with regulations. This may include measuring the airflow, temperature differentials, location of sensors and refrigerant pressures.
Report and recommendations: Based on the inspection findings, the inspector will prepare a report detailing any issues with the system and recommendations for improvements. The report will also include an assessment of the system’s compliance with regulations and any necessary remedial actions.
When the TM44 inspection is complete, you’ll usually receive a report detailing the findings with any areas for improvement. The report provides information on the condition, efficiency, and compliance of the system with regulations. Here is a breakdown of what is typically included in a TM44 report:
Executive summary: This section provides an overview of the report and highlights the key findings and recommendations.
Building information: This section provides information about the building, including its use, size, and location.
Air conditioning system information: This section provides detailed information about the air conditioning system, including its type, capacity, and age.
Inspection findings: This section details the findings of the inspection, including any defects, issues, or areas for improvement that were identified.
Energy efficiency recommendations: This section outlines recommendations for improving the energy efficiency of the air conditioning system, which can help to reduce energy consumption and save money on bills.
Compliance recommendations: This section outlines any recommended actions to ensure compliance with regulations, such as improving the maintenance and operation of the air conditioning system.
Technical appendices: These appendices provide detailed technical information about the air conditioning system, including diagrams, measurements, and calculations.
The exact format and content of a TM44 report may vary depending on the specific requirements of the inspection, but it should always provide a comprehensive assessment of the air conditioning system and recommendations for improvements.
If you fail to comply with a TM44 inspection, there may be several consequences, depending on the circumstances:
Legal action: Failure to comply with a TM44 inspection may result in legal action being taken against you, which could lead to fines, penalties, or other sanctions.
Invalid insurance: If you are required to have a TM44 inspection by your insurance provider and you fail to comply, your insurance policy may become invalid, which could leave you liable for any damage or losses that occur.
Non-compliance with regulations: Failure to comply with TM44 regulations may result in your building being non-compliant with relevant regulations, such as the Energy Performance of Buildings Directive (EPBD). This could lead to further legal action or penalties.
Higher energy costs: If your air conditioning system is not operating efficiently, it may be using more energy than necessary, which could result in higher energy bills.
Poor air quality: If your air conditioning system is not properly maintained, it could lead to poor air quality within your building, which could affect the health and wellbeing of occupants.
