Duct Sealing & Insulationin Miami
Measured duct leakage testing and sealing so the air you pay to cool reaches the rooms.
About this service
Typical duct systems lose a significant share of their air through leaks at joints and connections. In a Florida attic that means cooled air is lost into a space that is hotter than outdoors, while return leaks draw humid, dusty attic air into the house.
We measure leakage with a duct pressure test before and after the work, so you have a figure to judge the result by.

Duct Sealing & Insulation: common questions
Is duct sealing worth it on an older home?
Older homes usually benefit most, as long as the duct material itself is still sound. If the ducts are deteriorated, replacement is the better investment and we will say so.
