Ductwork Insulation
Prevent heating and cooling loss by insulating the ducts that move air through your home , especially in areas like attics, crawl spaces, or unfinished basements. If you’ve been searching for duct insulation near me or noticing uneven temperatures in certain rooms, this upgrade can make a measurable difference in comfort and energy efficiency.

About This Service
Insulating your ductwork protects the air your HVAC system works to heat or cool. Without insulation, air loses its temperature as it travels through unconditioned spaces, especially in older homes or those with ducts running through attics and crawl spaces.
We install high-quality duct insulation that improves comfort, reduces energy bills, and extends the life of your HVAC equipment by lowering system strain.
Frequently Asked Questions
Is duct insulation part of a larger upgrade?
Often, yes. We combine it with Aeroseal duct sealing, attic insulation, or full home performance upgrades to maximize energy efficiency.
What materials are used?
We use foil-backed fiberglass wrap, duct board, or spray foam insulation, depending on the system’s location, layout, and access.
Where is duct insulation most important?
Attics, crawl spaces, garages, and basements, any area where ducts pass through spaces that aren’t temperature controlled.
Why insulate ductwork?
Insulated ductwork helps keep heated or cooled air at the proper temperature as it travels through unconditioned spaces, saving energy, improving comfort, and supporting HVAC efficiency.
Will this impact airflow?
Yes, in a good way. Proper insulation reduces thermal loss and supports more accurate temperature delivery and airflow balance.
