No Return Policy

Air Handling Systems by Manufacturers Service Co., Inc. has a long-established NO RETURN POLICY, based on Cross Contamination Dangers, examples of which have been highlighted in the news headlines recently.

Air Handling Systems does not accept for return, any material that has left our facility. There is always the possibility of contamination from an unknown source. When component parts are delivered to your location, they generally are placed in the area where dust or fume contaminates will be collected. This allows dust or fumes from this location to migrate into the packaging and onto the ductwork, as parts may have been left unpacked in the area. Some components could have been temporarily installed, further tainting them.

Where it is possible that your ductwork has not been contaminated, Air Handling Systems must be prudent and refuse to accept return shipments. Allowing possible contaminated components into our warehousing location can cause Cross Contamination Dangers with new material located in the shipping area, and expose both our employees and our customers to possible hazards.

Some of our customer’s ductwork handles food products. Other customers produce many forms of wood products. Many of our customers are in the metalworking industry, others are pharmaceutically related, electrical power plants, construction, mining, oil discovery, textile, petroleum, plastics, clean rooms, electronics, and laboratories. Our customer base covers all industries, generating different types of dust and fumes that our other customers do not want endangering their operation.

Air Handling Systems by Manufacturers Service Co., Inc. also has a long established NO RETURN POLICY, for ALL Custom Fabrications. Custom items are made to your specifications, they are not returnable for any reason. Orders cannot be cancelled or changed once production has begun.
