Signs your ductwork needs to be repaired
Feeling Drafts?
Drafts or uneven temperatures may signal issues with your ducts. Poorly sealed or uninsulated ducts can cause air leaks, reducing HVAC efficiency
High Energy Bills
A sudden spike in energy bills often signals HVAC inefficiencies. Leaky ducts make your system work harder, using more power to maintain comfort
Frequent HVAC Repairs?
Constant HVAC repairs can be a red flag. Overworked systems, often due to unsealed or poorly insulated ducts, wear out faster and require more frequent repairs
Check for Visible Damage
Inspect your ductwork. Visible gaps, tears, or loose connections can signify a need for encapsulation and sealing
Professional Assessment
Hiring a certified professional is crucial. They’ll conduct tests to assess if duct sealing, encapsulation, or insulation is needed

Why Replace Crawl Space Ducts?
Over time, crawl space ductwork can become torn, crushed, rodent-damaged, or filled with debris and mold. Leaky or collapsed ducts restrict airflow, causing uneven temperatures, increased energy bills, and unnecessary strain on your heating and cooling system. Replacing them ensures your air gets where it’s supposed to—cleanly and efficiently.

Insulation acts as a barrier; this is what slows down the transfer of heat. This will ensure the air inside your ducts remains at the desired temperature as it travels throughout your home. This minimizes heat loss or gain; insulation will allow the HVAC system to work more efficiently.
do you need a professional to insulate your ductwork?
Professional insulation protects your home properly. We recommend having a professional take care of it if you want all of the benefits of optimal energy efficiency. Our team at Insulation Co. LLC has the knowledge and experience to select insulation material with the right R-Value for your ducts, and to install it correctly to ensure it lasts as long as possible.

Why you can't use cellulose for DIY duct insulation?
Cellulose insulation is a blown in insulation product, which requires specific machines. It also can be time-consuming for a homeowner but as a professional company insulating with Cellulose takes a lot less time, whereas doing it yourself can take weeks. Cellulose can be more difficult to work with, and you will find it difficult to apply this insulation without leaving any gaps.
