Hi Sparky! The National Fire Protection Association and the Chimney Safety Institute of America recommend inspecting and sweeping your chimney at least once a year. Some chimneys vent heating systems as well. If your chimney has a flue for venting your heating system, that part should be inspected and swept as well. Note I mention inspection as well as cleaning. This is important because your safety is dependent not just on the removal of the flammable creosote, but also dependent on the condition of your chimney and fireplace. Defects in the chimney can be hazardous. I hope you find this helpful, thank you for asking! Billy Sweet
