Massachusetts*, New Hampshire** and Maine require blower door and duct leakage tests to be performed on new homes before an occupancy permit is provided. GDS Associates has performed thousands of these tests over the past ten years. As BPI, RESNET and ENERGY STAR® certified energy specialists, we are your best choice for accurate, reliable and timely code testing services including:
From architects to general contractors and builders, your hard work boils down to the Certificate of Occupancy…and the house must pass a blower door and duct leakage test to get it.
You have had to comply with many permitting regs and building codes before and during construction. Not all issues become a sticking point, but many cities and towns are adamant that you provide blower door and duct leakage test results. GDS can help you not only meet, but exceed the residential energy code.
At what point in the building process should I contact you?
If you want the ducts tested in the rough, call us when the ducts are installed. Otherwise, call us a couple days before the home is complete. We’ll send a tester there as soon as possible.
When should the blower door test be conducted?
We suggest conducting the blower door test as near to the closing date as possible. The more complete the construction is, the better the house is likely to perform.
When should the duct leakage test be conducted?
We recommend conducting a duct leakage test in the rough, before the ducts are hidden behind finished walls. This will give you a chance to fix any leakage before the closing. However, they can also be tested the same day we do the blower door test.
What is your turnaround time in giving us the tests results?
To do both a blower door and duct leakage test takes about an hour, depending on the size of the house. We will give you the test result forms before we leave.
How do I prepare for the tests?
Following these guidelines will help ensure a smooth test and the best possible score. If the test is for code compliance, your score requirement is based on the volume of the house. It would be very helpful if you could provide this number, or at least the home’s square footage.
There will be a charge for all scheduled tests that are not ready, require a second trip or require significant extra time onsite.
