SM & IAQ Diagnostics utilizes award winning patented robotic technology and we follow strict standards based on NADCA ACR 2013 standards for Assessment, Cleaning & Restoration of HVAC System. This standard, produced by NADCA, is used only by registered members of the organization to ensure that HVAC systems are professionally cleaned. Air conditioning systems act as the "lungs" of the building and it needs to be maintained not only for cooling but more importantly the cleanliness of the HVAC system and its air ducts. Over time, contaminants such as building debris, dust, hair, animal dander, fibers from clothing and carpets, pollen, tobacco residues and many more accumulate inside the ducts and on the cooling coils resulting in growth of bio-film, mould and bacteria that is well documented as a major cause of respiratory illnesses and triggering asthma attacks.Air ducting system, which has not been cleaned and remediated between 3 – 5 years, increases the usage of Energy and creates "Sick Building Syndrome". Primary air filtration in a HVAC system does not stop dust particle & microbial build-up in the air condition ducts.

We provide advanced robotic solutions that cater to various types of industries and their processes.

Data Centres and Computer rooms are without question the heartbeat and engine room of any organisation. Unplanned downtime will cause major expense and disruption to your systems and operations, not to mention the potential loss of valuable company revenue.Data Centre cleaning schedule is a crucial first step in the process to protect against equipment and system failures caused through contamination. Hardware manufacturers are now dictating that IT critical environments are maintained to a very high level of cleanliness in order to ensure their equipment is only exposed to the very minimum of contamination. It has now become vital that a data centre receives an efficient schedule of care to minimise the risk of unplanned downtime. This will in many cases include floor void cleaning, ceiling void cleaning, floor tile cleaning, external rack cleaning, internal rack cleaning, A/C units, PDU's, high level cable trays, trunkings, doors and ledges. In some instances it may be necessary to perform an initial deep clean in order to ensure the facility is brought up to an acceptable standard of cleanliness before regular standard service cleans are performed. Floor void cleaning is a crucial factor to any controlled IT environment as this helps remove the risk of dangerous traces of contamination from circulating throughout the room and equipment. Machine cleaned vinyl floor tiles will provide a safe non slip surface to walk and give the room that 'clinical clean' appearance. From our vast experience a room that is maintained clean and tidy will often result in less staff turnover while providing a safer all round working environment for both operators and equipment!

Data Centres and Computer rooms mainly house rows of racks containing an assortment of business critical equipment. Dust and contamination will cause extreme problems if not correctly addressed. All accessible surfaces of equipment are vacuumed using triple stage filtration equipment and wiped where necessary with anti-static cloths. Clean dust free fans and vents will help reduce power consumption and also help address cooling issues.

Data Centres and Computer rooms are often designed to suit each customer's individual requirements, therefore making each room and environment unique. Our approach to the cleaning operation is to treat every environment on an individual basis. Regular cleaning schedule will be a major step towards protecting and ensuring the smooth efficient operation of your systems.

Foul smelling odours are caused by a mixture of chemicals released from proteins, bacteria and organic matter and if left untreated they will multiply and spread further. This leads to the odour intensifying making it increasingly difficult to contain and eliminate. Environments such as factories, houses, retail outlets, commercial premises, healthcare establishments and food preparation areas can all suffer from problems with malodours. Offensive smells are not only off-putting for your employees they are also unpleasant for your customers. Failure to remove unpleasant odours can have a negative effect on productivity, profitability and the reputation of your business. Our removal service provides a rapid and cost effective solution for areas suffering from foul smelling odours. We identify the source of offensive odours and quickly and efficiently neutralises and eradicates the pungent smell leaving a fresh and clean smelling environment.



Fire & Flood

Fire damage to your personal property can be very traumatizing. Once the shock wears off and the fire is out you’re left with three distinct damage possibilities. Even after a small fire, soot and smoke can contaminate everything, the flames themselves can consume everything from curtains and furniture to whole walls and floors, the water used to extinguish the flame may cause corrosion, mold, and mildew growth and may even be a bigger problem than the fire. To get your life back as soon as possible you need a quick response from well trained, well equipped personnel with the latest knowledge in cleaning, deodorizing, and the ability to coordinate the removal of contents and the damaged material. At Soma Medical & IAQ Diagnostics we have experienced project managers, a fully staffed contents and structure cleaning division, and a construction division that knows just how far to go to be thorough. Our experience in fire restoration goes a long way in providing all the necessary knowledge and resources to restore your property and your peace of mind.


Water is one of the most destructive forces when it escapes the confines of the plumbing or drainage system or enters the interior of the structure from the outside. The longer the structure or contents remains exposed and unattended the worse it gets. It has the potential of not only corrosion and disintegration but also of molds, mildews, and bacteria that over time may create a wide range of health problems to both the residents and workers in the damaged building. Whatever the cause or extent of the water damage, your house and its contents must be dried out quickly and effectively. From the moment you call, we can step in with the best solution to keep damages to a minimum. Soma Medical & IAQ Diagnostics recognize the dangers involved and thus is available to respond 24 hours a day, 7 days a week. By incorporating the science of drying, special training, and our immediate response, the loss is limited to just the affected areas and flood restoration time is minimal. Each drying project is unique and requires the training and equipment and strategy to do what needs to be done to remediate it in the most effective manner. Large losses and sensitive environments require special equipment including commercial drying equipment, generators, site supervision, and resources necessary to reduce business interruption and expedite the claims process.


Dust and other contamination accumulate on the surfaces of HVAC system during its construction and operation. HVAC systems should be cleaned at regular intervals, especially if the system conveys very combustible material such as grease or organic dust. The national regulations and guidelines give time periods to inspect cleanliness of HVAC system, limit values for dust accumulation and time periods to clean HVAC system. The aim of this study was to develop a verifying concept to control and verify the cleanliness of HVAC systems.

Contaminations and their measuring methods.

The contact method and the swapping method were studied to measure the microbe concentrations on the duct surface. The laboratory and field studies showed that the microbial concentrations measured with the contact method were lower than with the swab method. The upper detection limit of the contact method was 5–10 CFU/cm2.

Two tape sampling methods, the gelatine and the carbon tape, were studied to measure mineral fibre contamination on ventilation ductworks. The samples were collected from the duct surfaces and analysed with an optical and a scanning electron microscope (SEM). The gelatine tape was found to be suitable for light microscopic analyses and it allows counting the fibres on the surface. The carbon tape was applicable to SEM analyses and the method allowed the analysis of the chemical composition of fibres. The mean fibre concentration of the studied HVAC system was 112 fibres/cm2 (11–1490 fibres/cm2) measured with the gelatine tape.

The visual evaluation method with a visual cleanliness scale and an visual inspection form has been designed to use it as a primary method to evaluate the cleanliness of HVAC system. A robot with a video camera is used to reach the visual inspection into the whole ductwork.



A simple comb method (Figure 1) was developed to evaluate the thickness of dust and debris layer on the duct surface. The developed comb and the deposit thickness test (D.T.T.) method introduced in the British guideline (Figure 2) were tested in the laboratory and in the field.  The results of the deposit thickness methods were compared with the vacuum test method (Figure 3). The laboratory tests showed that the dust accumulation measured with the comb method correlated with the vacuum test method (R2= 0.5–0.9) when the dust layer was homogeneous. However, no correlation was found when dust accumulation was heterogeneous. In the field test, the mean amount of the grease layer varied between 34–142 g/m2 measured with the vacuum test method and 0.1–1 mm measured with a comb method. The correlation between the comb and the vacuum test method (Figure 4) and between the D.T.T. and the vacuum test method (Figure 5) was 0.84 and 0.9, respectively.

A visual cleanliness scale, a visual inspection form and a simple deposite thickness comb have been developed for the systematic visual evaluation of the cleanliness of air ducts. A robot video camera is used to reach the visual inspection into the whole ductwork. The amount of dust and debris is measured with the vacuum test method and the thickness of the grease layer with the D.T.T. method if the cleanliness level of the ducts is not clear enough visually. The microbial contamination will be measured with the contact method and the fibre contamination with the tape sampling method.
