Assessing Air Tightness
A blower door test is a highly effective way to measure the air tightness of your home. Furthermore, by using a powerful fan to depressurize the house to 50 pascals, equivalent to a 20 mph wind on all sides of the residence, our experts can determine areas where air leakage occurs. After all, investing in blower door testing can help you identify and address areas of energy loss, leading to lower energy bills and increased comfort.
Understanding the Results of a Blower Door Test
The auditor then makes some various calculations from the blower door test in order to give you the results. Below are some terms that the auditor may speak to when referring to the results of a blower door test:
This refers to Air Changes Per Hour at the 50 pascals. The system will replace the total volume of air in your home 5 times every hour. The lower the number the tighter the exterior envelope of the house is. It is important to note that anything at 2 ACH at 50 and below requires fresh exchange from your HVAC system for health and safety reasons.
This refers to cubic feet per minute at 50 pascals. It helps the auditor/homeowner understand how much air is moving from the house to the outside. The results of this number are helped to calculate ACH at 50. A tighter sealed envelope is usually under 1250 CFM at 50 and anything above 2500 would be considered a very leaky home.
If the results of your blower door test conclude that you need to focus on air sealing your home, the auditor should work with you to prioritize areas that are the worst.
It is also important to test out your home after any air sealing improvements have been made for health and safety reasons. Schedule a test or energy audit today!
