Thinking of building a new home or putting on an addition? Make sure you’re sticking to the code and getting a blower door test done. Georgia building code can be complex and hard to understand, but at Energy Conservation Solutions, we are experts who work hard to make sure your home meets DET and BET testing required by the state of Georgia.

Georgia building code requires a building envelope test for all new homes, as well as retrofits to homes that add more than 50% of square footage. The guidelines put in place in 2011 dictate that the building envelope not allow more than 7 air changes per hour at 50 Pascals.

The code also requires a duct blaster test to ensure tightness of the duct work system for all new duct work and any retrofit that impacts over 50% of the ductwork system.Testing of duct systems can be done at either rough-in or post-construction stages. For rough-in testing, the total leakage must be equal to or less than 6 cubic feet per minute at 25 Pascals (CFM25) for every 100 square feet of conditioned floor served by the duct system. Post-construction testing allows leakage to outside of up to 8 CFM25 per 100 square feet of conditioned floor, and total leakage for post-construction testing must be equal to or less than 12 CFM25 per 100 square feet of conditioned floor.

BET Testing – Blower Door Test

Building envelope testing (BET) is done through blower door testing. A blower door is attached to a doorway of the home or addition, with the house slightly depressurized. The blower door pushes air into the home and reads how much escapes through leaks. The more air needed to get the home to the correct pressurization indicates more leaks. We use the best equipment in the industry and have the most highly trained staff you could ask for.

DET Testing – Duct Blaster Test

Duct envelope tightness (DET) testing uses a duct blaster to test for leaks in the ducts and insulation. The duct blaster, which is similar to the blower door mechanism, secures to a return vent, then all other supply and return vents get sealed off. The blower then pressurizes the duct system and detects any leaks in the duct and insulation system. Again, we use the best technology available. Our well-trained professionals make sure that your home is up to par so you can feel confident that Georgia’s standards are met and your standards are exceeded.

Duct Blaster & Blower Door Testing Cost

Energy Conservation Solutions is ready to help you meet these code requirements and to save you money and time. Our pricing structure is below and will increase slightly outside of 20 miles from downtown Atlanta to account for drive time:

    • 1 Blower Door – $150
    • 1 Ductblaster – $175
    • Blower door and up to two duct blaster tests – $250
    • Each additional duct blaster required – $50
