Air Conditioning Installation

We provide professional air conditioning installation services tailored to the specific requirements of your space. From initial design through to commissioning, every system is installed to deliver efficient, reliable performance.

We assess the layout, usage, and thermal demands of the environment to ensure the correct system type and capacity are selected.

Systems we install include:

  • Split air conditioning systems

  • Multi-split systems

  • VRF and VRV systems

  • Central air conditioning systems

All installations are carried out to a high standard, ensuring systems operate efficiently from day one and continue to perform over the long term.

TM44 Air Conditioning Inspections

We provide TM44 air conditioning inspections in line with current regulations, helping businesses ensure their systems remain compliant, efficient, and safe to operate.

TM44 inspections are a legal requirement for air conditioning systems with an effective rated output of over 12kW and must be carried out every five years.

What a TM44 Inspection Covers

A TM44 inspection includes a detailed assessment of your system, including:

  • System efficiency and overall performance

  • Condition of equipment and components

  • Suitability of the system for the space

  • Controls and operation

  • Maintenance standards

  • Identification of potential improvements

A full report is provided following the inspection, outlining findings and recommendations.

Who Requires a TM44 Inspection

TM44 inspections apply to:

  • Commercial buildings

  • Offices and retail spaces

  • Industrial facilities

  • Any premises with air conditioning systems over 12kW

If you are unsure whether your system requires an inspection, we can provide guidance and arrange the necessary assessment.

Why TM44 Inspections Are Important

  • Ensures legal compliance

  • Improves system efficiency

  • Reduces energy consumption

  • Identifies issues before they develop

  • Helps extend system lifespan

TR19 Duct Cleaning

We provide TR19-compliant duct cleaning services in line with the recognised UK standard for internal ventilation hygiene.

TR19, issued by the Building Engineering Services Association (BESA), sets out the requirements for inspecting, cleaning, and certifying ventilation systems to ensure they remain safe, clean, and fit for purpose.

While TR19 applies to general ventilation systems, it is particularly important for commercial kitchen extract systems, where the build-up of fat, oil, and grease can create a serious fire hazard.

What TR19 Duct Cleaning Involves

A TR19 duct cleaning service involves a full inspection, cleaning, and verification process to ensure the system is returned to a safe and compliant condition.

This typically includes:

  • Pre-clean inspection of the system

  • System mapping and identification of access points

  • Wet film thickness testing where required

  • Before photographs of internal duct condition

  • Installation of access panels where necessary

  • Mechanical and manual cleaning of internal ductwork

  • Removal of grease, dust, and other contaminants

  • Cleaning of associated components such as fans, filters, canopies, and hoods

  • Post-clean verification and testing

  • After photographs to confirm cleaning standards

  • Full reporting and certification

Post-Clean Verification and Reporting

Once the cleaning process is complete, the system is checked again to confirm that the required standard has been achieved.

Following successful completion, a TR19 post-clean report can include:

  • Summary of the work carried out

  • Pre- and post-clean test readings where applicable

  • Before and after photographic evidence

  • System schematic showing access points

  • Certificate of cleanliness

  • Recommendations for future cleaning intervals

This documentation is important for compliance, record keeping, and insurance purposes.

The Cleaning Process

TR19 requires the entire ventilation system to be cleaned, not just the visible or easily accessible sections.

Where required, additional access panels may need to be installed to allow safe and effective access throughout the ductwork.

Cleaning can involve a combination of:

  • Mechanical brushing

  • Manual scraping

  • Degreasing treatments

  • Specialist cleaning methods suited to the system type

The aim is to remove built-up grease, dust, and contaminants without damaging the system, while restoring the ductwork to a safe and compliant condition.

Why TR19 Compliance Matters

Fire Safety

Grease deposits within extract ductwork can present a major fire risk, particularly in commercial kitchens. Regular TR19 cleaning helps remove this hazard and reduce the risk of fire spreading through the system.

Insurance Requirements

Many insurers require evidence of regular, compliant duct cleaning. Without valid documentation, claims following a fire or related incident may be affected.

Hygiene and Compliance

Clean ventilation systems help support a safer, healthier environment for staff, customers, and building occupants, while also supporting wider fire safety and maintenance responsibilities.

Where TR19 Is Most Relevant

TR19 duct cleaning is particularly important for:

  • Commercial kitchens

  • Restaurants and catering premises

  • Hospitality venues

  • Food production environments

  • Buildings with heavily used extract systems

  • Commercial ventilation systems requiring hygiene management

Repairs & Diagnostics

If your system is not performing as it should, we provide fast and effective fault finding and repair services.

We carry out detailed diagnostics to identify the root cause of issues and carry out the necessary repairs to restore performance.

Our repair services include:

  • Fault finding and diagnostics

  • Electrical fault identification

  • Component repair and replacement

  • Leak detection

  • Regassing

  • System performance testing

Our approach focuses on resolving issues efficiently while reducing the likelihood of recurring faults.

Maintenance & Servicing

Regular maintenance is essential to ensure systems continue to operate efficiently and reliably. Without routine servicing, performance can decline and the risk of breakdowns increases.

We provide both one-off servicing and planned maintenance tailored to your system and usage.

Our maintenance services include:

  • System performance checks

  • Filter cleaning and replacement

  • Condenser and evaporator coil cleaning

  • Refrigerant level checks

  • Electrical component inspection

  • Airflow and performance testing

  • Early fault detection

Routine maintenance helps extend system lifespan, reduce energy consumption, and minimise unexpected failures.
