and no duct repair.)

DISCONNECTED DUCTS are surprisingly common.

In a study of energy-efficient measures, DOE’s Energy Information Administration reported that sealing the ducts yielded by far the greatest energy savings of the 12 measures studied, at the lowest cost. 

A study of 24 Florida homes found air-conditioning energy use was reduced by 18% after duct repairs were made.

Fiberglass PLUS

Call Barbara Clark at 772-778-1815

Owner Barbara Clark’s lifetime of construction experience and building science education led her to develop the Fiberglass PLUS program. Multiple national studies have concluded that duct leakage averages about 20% so it made sense to repair these ducts before covering ducts in 12” of fiberglass. Leaking ducts can also be a source for mold (cold dry air meeting hot humid air causes condensation which creates perfect conditions for mold growth.) It really is hard to imagine but over 20% of your AC could be blowing into your attic.

Fiberglass PLUS includes ducts tested for leaks with non-toxic theatrical smoke then repaired, and the installation of 12" of blown-in Owens Corning fiberglass insulation. Fiberglass PLUS combines the two most cost efficient energy upgrades you can make to your home.

SEALING DUCTS AND INSTALLING R-38 insulation will lower your bills and make your home much more comfortable.

According to the Department of Energy, duct repair is the most cost efficient energy improvement.Fiberglass_Plus_files/Air%20Sealing%20Report.pdfFiberglass_Plus_files/Air%20Sealing%20Report.pdfhttps://www.google.com/ig?hl=en&client=safari&rls=en&btnG=Searchshapeimage_5_link_0shapeimage_5_link_1
“As a long-time building contractor 
I just cannot bring myself to bury obvious, dangerous, or energy wasting attic problems with insulation.
