INSULATION

Having insulation within the HVAC unit prevents mold from developing within the system. If mold grows within the coils, you and all your patrons are breathing that in. 

However, many old HVAC systems contain fiberglass, a material that is now banned in some states for being cancerous. Over time, the insulation within the unit falls or tears. It can get caught in the belt and cause a service call. 

At SEfilter we provide an FDA approved, cool-shield bubble wrap insulation. It prevents mold, sticks with no risk of tearing, and is composed of safe materials.
