How to ensure Duct Cleaning work was carried out properly?

Any commercial property has a legal obligation to ensure its ductwork is cleaned and maintained regularly. Ventilation and air conditioning systems should be subject to a regular maintenance schedule to ensure that air quality meets legal standards, workforces are protected and insurance companies are satisfied.

Duct cleaning should be carried out by a fully qualified and accredited team. In doing so, employers can ensure they’re meeting legal standards. However, after having your ductwork professionally cleaned, how can you verify the work carried out?

Visual Inspection

The most simple way to check any duct cleaning work would be to have a visual inspection of the equipment. To do this properly, it’s advised to look at any ductwork systems before work is carried out, so you can see a visual difference after completion.

Ductwork can build up dust and debris, which is obvious to the naked eye. Following duct cleaning work, equipment should be noticeably cleaner. However, while a visual inspection is quick and easy to carry out, you may miss aspects that are more hidden and difficult to spot.

Before & After Evidence

At Deduct, we provide HD videos of your ventilation system on request with every job. Similar to carrying out a visual inspection, a before and after video will show the result of cleaning work.

Photographic evidence and schematics are detailed in your post-clean report. However, a video of specific locations or items of equipment can be much more informative.

Clean hospital ductworkHygiene Certificate

Following the completion of any duct cleaning work, we will provide an insurance compliant certificate for your records. This certificate is proof of the works that have been carried out and suitable for satisfying any requirements from insurers.

Micron Readings Report

Microns are a unit of measurement. The level and frequency of duct cleaning should be based on these figures. BESA released new technical requirements for TR19 in relation to legal requirements for duct cleaning. Providers must supply a post-clean report (PCR) that includes recommendations based on micron readings.

The report itself must detail micron readings for each test location, which can give you an idea of any air quality issues. Where readings exceed certain thresholds, you can see where duct cleaning is needed more regularly.

Conclusion

There are many ways to ensure that duct cleaning work has been carried out properly. Owners and employers need reassurance that their ductwork has been cleaned to a high standard to ensure the safety of their workforce, meet legal obligations and satisfy insurers.
