Ans: Well, choosing an AMC is always advisable than to clean chimneys personally. This is primarily because the chimney may have clogged filters. The extensive or frequent cooking may result in dense deposits of grease and oil on the chimney. It is always advisable to opt for an AMC with the manufacturer, who will offer services for cleaning, repair, or maintenance periodically. You can also tie-up with a reputed company offering similar services.
