Energy Star provides services for you to get duct insulation done. You can also buy the accessories needed from home depot or Lowes and do it yourself.
Foil and Fiberglass Duct Insulation is best.
To wrap ductwork, start by cleaning the surface to ensure proper adhesion and insulation performance. Measure and cut insulation material, such as fiberglass or foam, to fit around the duct. Secure the insulation with duct tape or foil tape, ensuring there are no gaps or exposed areas. Finally, ensure that the insulation is snug but not overly tight, allowing for some expansion and contraction of the ductwork.
Duct tape can affect the insulation of PVC cable by potentially degrading it over time. The adhesive used in duct tape may react with the PVC, leading to a breakdown of the insulation properties. Additionally, if the tape is applied tightly, it could trap moisture, which might promote corrosion or other issues. Overall, while duct tape can provide temporary fixes, it is not recommended for long-term insulation of PVC cables.
Duct tape is a good insulator because it has a low thermal conductivity, meaning it does not readily transfer heat. It is also flexible and has a tight adhesive seal, which can help trap air and create a barrier that blocks heat transfer. However, duct tape may not be as effective as specialized insulation materials designed for thermal insulation.
Duct tape does not provide insulation, but it can be used to seal ductwork or repair items temporarily. For insulation, it is better to use materials specifically designed for that purpose such as foam insulation or fiberglass.
No, duct tape should not be used as a substitute for electrical tape for electrical insulation purposes. Electrical tape is specifically designed to provide insulation and protect against electrical currents, while duct tape may not provide the same level of protection and could pose a safety risk.

Using rigid duct insulation in HVAC systems provides benefits such as reducing energy loss, improving system efficiency, preventing condensation, and enhancing indoor air quality.
If insulation on the inside of duct comes loose, it can reduce the efficiency of the HVAC system by allowing conditioned air to escape through the loose insulation. It may also lead to poor indoor air quality as the insulation particles can circulate in the air. Additionally, loose insulation can create a fire hazard if it comes into contact with hot surfaces.
