Keep the cool cool and the warm warm.
Ducts in a hot attic or a cold crawl space gain and lose heat on the way to your rooms. Proper insulation keeps the air at the temperature you paid to make.
- Order: Seal first, then insulate
- Materials: Insulated sleeves and sealed jackets
What it is, and why it matters.
Attics in a Tennessee summer can be far hotter than the house, and crawl spaces in winter are cold. Bare or poorly insulated ducts there absorb heat from the attic in summer and lose it in winter, so the air arrives in the rooms warmer or cooler than it should be and the system runs longer.
Nashville HVAC adds and repairs duct insulation across Middle Tennessee. We seal ducts first, because insulating a leak does not stop it, then wrap or replace insulation sleeves with the right thickness and a sealed vapor jacket so condensation does not soak the material.
Four things done right.
Seal first
Leaks are fixed before insulation goes on.
Right thickness
Insulation is matched to where the duct runs.
Condensation control
A sealed jacket keeps moisture out of the insulation.
Visible improvement
Rooms get air closer to the temperature the system made.

Duct Insulation: common questions
Why do my ducts sweat?
Cold ducts in humid air collect condensation. Missing or damaged insulation and a lack of a vapor seal are the usual cause, and insulation with a sealed jacket helps.
Is attic duct insulation worth it?
In hot attics it often is, because uninsulated ducts there gain a lot of heat. We can show you how much your ducts are exposed.
How do I get an estimate for duct insulation?
