What is a HVAC audit?

We conduct inspections of the HVAC systems at the client's premises usually after hours when the system can be shut down.  We physically inspect all the plant and equipment and the inside of the air ducts.  We take pictures of our findings, and togethter with the assistance of the plant drawings we produce a comprehensive report detailing and showing the findings and our recommendations and costs for refurbishment.

Do you charge for HVAC audits?

Yes, we do.  The reason we do, is that our audits are conducted by recognised IAQ Scientists and often involve cutting access into the system.  These audits are designed to provide our clients with information for the purposes of long term budgeting and planning.

When do you conduct duct and coil cleaning work?

If the building can be accessed during the day then the work will be conducted during a day shift.  If not, then the restoration work will be conducted between the hours of 18.00 hours and 06.00 hours.

How can we be sure that you will not contaminate other areas of the building with disturbed dust and odours from the bacterial and fungicidal treatments?

We isolate the areas where we are working using containment barriers which are positioned into the ducts and prevent the ingress of dust and odours to other areas of the building.  We extract the dust which is collected in HEPA filters.  The containment barriers are only removed once all dust is removed and the treatments have cured there emitting no further odours.

How do you gain access into the ducts?

We cut out inspection openings which comply with NADCA standards to gain access for inspecitons, cleaning and treatments.  The ducts are then sealed using removable access panels which provide access for future inspections.

What are the advantages of regularly cleaning our ducting, air handlers and coils?

The answer is firstly, healthy people who have a greatly reduced risk of contracting air borne illnesses and secondly, reduced pressure drops and improved plant effiiciencies due to better transfer rates both resulting in significant savings in the operating costs.

How often are inspections required?

How long is a piece of string?  This varies from site to site and depends upon the hours that the system is operated, the use of the building, the cleanliness of the air outstide and the quality and maintenance frequency of the filtration system.
