To fully address this question, we’ll first discuss what a blower door test is and then why your home may need one done.
Blower door testing is essentially a test that determines how airtight your home is. Seems pretty self-explanatory, but why would your home need blower door testing? Why does it matter how airtight your home is?
For starters, no one has ever liked a drafty house. It usually means there are potential other issues such as water intrusion, mold, and decay of building materials. How so? Well, the air is full of moisture—and in Florida, with higher humidity than many other places, even more so. So, if air is getting into your home, that means the moisture it is bringing in with it is settling on your walls, on your floors, in your HVAC system, on your ceiling, your attic…you get the picture. Over time, mildew and bold begin to grow, usually beginning in hard to notice areas. When mold is able to grow unchecked, it slowly eats away at the building materials, causing them to decay.
As an added downside, drafty homes also consume extra energy just to maintain the correct temperature and because air is constantly leaking, its not very comfortable temperature-wise.
So, blower door testing is just for old, drafty houses?
Only in part; blower door testing is also recommended on new construction homes. Builders have certain codes and requirements they have to construct homes to, but to ensure things were done correctly to ensure an airtight home, more than a visual inspection is needed.
