Duct Cleaning, HVAC & Air Ventilation System Maintenance

Pre Clean

Post Clean

Ventilation systems and ductwork can become contaminated and dirty over the period of their use, and issues are often hidden from general view. That is why regular ductwork cleaning is essential. The correct duct cleaning of ventilation units and the distribution ductwork and grilles is essential for the correct and efficient function of a building.

We undertake:

• Ductwork cleaning to BESA TR19 standards
• Hospital ventilation system cleaning to HTM03 01 standards
• Air Handling unit cleaning, filtration and refurbishment
• Cleanliness surveys and inspections
• Fogging or sanitisation of systems

All of our engineers are BESA qualified as a minimum standard and have attended manufacturer courses regularly to keep them up to date with the latest technologies and guidance.

VSS provide completion reports for all works undertaken. Our reports include photographic evidence, drawings and detailed recommendations.

We conduct indoor air quality testing as adequate fresh air supply and overall air movement is important for indoor well-being and to stop the transmission of the virus during the COVID-19 pandemic. 

It is important to complete the following:

• What does your buildings ventilation systems comprise of? 
• Assess the risks
• Make Changes 
• Monitor
• Review and Adapt

We use the latest technology and procedures and employ only trained, competent personnel. Our surveys of  ductwork systems and HVAC equipment including plant ensure continuous and efficient operation in line with industry guidance.

Survey provision:

• Indoor Air Quality Testing
• Internal surface cleanliness levels as per BESA TR19 / BS EN 15780 industry standards
• AHU cleanliness and condition reports
• Dust and Microbiological sampling of Ventilation surfaces
• Fire Damper Inspections as per BS 9999:2017

We carry out planned air conditioning maintenance in line with the manufacturers recommendations.

• FGas certification
• Cleaning and maintenance
• PPM programmes devised and implemented
• Replacement parts supplied and fitted
• New Air Conditioning systems designed, supplied and installed

All our engineers are FGas qualified as a minimum standard with manufacturer courses attended on a regular basis to keep them up to date with the latest technologies. As with all of VSS work a complete report of all works carried out, together with photographic evidence of conditions will be delivered to our clients

 

 

Air filter fitting in HVAC systems helps to stop the spread of particles, gases and emissions through the system. Our team of qualified engineers can carry out planned maintenance of air filtration filters. We can assess the condition of filters and recommend a programme, supply and fit all aspects and types of air filtration filters. We supply, maintain and install:

• Panel filters
• Bag filters
• Rigid pocket filtration
• HEPA filters
• Carbon filters
• Electrostatic filters
• Ozone purification systems

At VSS we provide quality engineers to fulfil the needs of all HVAC commissioning projects. Our works are in accordance with Part L Building Regulations, CIBSE guidelines and BSRIA application guides to meet current requirements and industry best practice:

• Pre-Commissioning
• Ductwork Pressure Testing
• Balancing and Commissioning of HVAC systems
• Pressure Regimes and Airflow Direction Checks
• Hospital HTM03 01 Validations
• Clean Room Testing
• Local Exhaust Ventilation (LEV) Testing in accordance to COSHH regulations
• BMS/Controls Commissioning and Testing
• Covid19 Compliance Surveys for HVAC systems
