Can I clean my smoke shelf myself?

• <div><p>You may be able to clean your smoke shelf yourself, though it depends on whether you can reach the shelf with the tools you have. If you cannot see through the chimney damper to the shelf, it’s better to rely on a professional chimney specialist. It’s also wise to get a professional if you see creosote buildup, which is typically hard, shiny, and sometimes sticky. A pro has the correct tools and safety equipment to properly clean out the chimney.</p></div>

Why insulate ductwork?

• <div><p>When you insulate ductwork, you help protect the air moving through the system from external conditions and keep it sealed within the ducts. This makes your HVAC system more efficient since it doesn’t have to work as hard to heat or cool your home. Insulation can help lower your energy bills and prevent problems like condensation and mold formation inside your ducts. </p></div>

Q: Does the EPA recommend duct cleaning?
