1. Will you accept NADCA certification (National Air Duct Cleaners Association) for this project in lieu of the certification requirements listed in this solicitation from Chimney Safety Institute of America (CSIA)? Yes

2. Please clarify that when a pricing option says Air Handler Unit it just means to clean the air handler unit only unless it specifically says to clean related ductwork.

4. Is there a schedule of Air Handlers showing CFM or tonnage? Schedule for AHU.

Tonnage and CFM not available.

5. During the site visit it was mentioned that cleaning was only for the duct that can be reached by diffusers, Is this correct? My understanding is that the solicitation was wanted for cleaning the duct in its entirety; which is not hard to accomplish in this facility.

Clean duct work back to the AHU.

6. It was noticed that the price sheet there are a few line items that you’re asking for quarterly. I understand doing this for Kitchen Exhaust, but for AHUs with complete duct system might be excessive? For example, line item 0009. Clean the critical areas OR/SPS’s on a quarterly basis.
