Improper airflow in a home can cause problems. It can drastically affect heating and air conditioning efficiency. Did you know that 25-45% of heat loss in some homes can be attributed to air leakage? For this reason that we offer Walnut Creek blower door testing as part of our home energy audits.
Blower door testing was actually invented back in the 1970s. Testing equipment consists of a very powerful, variable speed fan mounted in an adjustable doorway panel. The fan pulls air from the home which causes the internal air pressure to drop. Dropping the air pressure causes exaggerated air leaks which makes the leaks easier to find.
We use different tools to find the exaggerated air leaks, including infrared and even "smoke puffers". Once leaks are discovered, we can calculate the amount of air that will travel through the leak in normal, non-exaggerated conditions. But we don't rely on these calculations alone, as weather, indoor activity and other variables can drastically affect them.
Indoor air quality is also important in addition to our Walnut Creek blower door testing service. If a home is sealed for efficiency, things like ventilation and indoor combustion must be addressed to avoid a health risk. Call us today to learn more about blower door testing for your home!
