Our Services
We provide complete air conditioning and ventilation solutions, covering everything from system design and installation to maintenance, repairs, and upgrades.
Our services are tailored to commercial, residential, and industrial environments, with a focus on reliability, efficiency, and long-term performance.
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
If you require TR19 duct cleaning or would like advice on whether your system needs inspection and cleaning, get in touch with Tech Mech to discuss your requirements.
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.
Ventilation Systems
We design and install ventilation systems that improve airflow, control temperature, and maintain a healthy indoor environment.
Our systems are tailored to the specific requirements of each space, ensuring effective air movement and air quality control.
Our ventilation services include:
Mechanical Ventilation with Heat Recovery (MVHR)
Energy Recovery Ventilation (ERV) systems
Fresh air supply systems
Extraction and exhaust systems
Commercial kitchen extraction
Bathroom ventilation systems
Industrial ventilation solutions
All systems are designed to provide consistent performance and efficient operation.
Ductwork Installation
We provide professional ductwork fabrication, installation, and modification to support efficient airflow and system performance.
Ductwork is designed and installed to suit the layout of the building, ensuring proper airflow, sealing, and insulation.
Our ductwork services include:
Custom ductwork fabrication
Installation of rigid and flexible ducting
Ductwork modifications and rerouting
Sealing and insulation
Airflow balancing
Correct ductwork design is essential for system efficiency and long-term performance.
