Your home is supposed to keep the outside air outside. A blower door test shows how well it’s doing that. We gently lower the air pressure inside your home, outside air comes in through every crack and gap, and we measure how much. Then we find where it’s coming in.
Every bit of air that leaks into your home has to be cooled and dried by your AC. In Florida, that air is hot and full of moisture most of the year, so leaks don’t just raise your bill. They raise your humidity too.
That’s why a leaky house can feel sticky even when the thermostat says 75°. Leaks can also pull in dust, pollen and air from the attic and garage.
A leaky house is only part of the story. Sealing air leaks helps, but if your AC is the wrong size or wasn’t installed right, sealing alone won’t fix a high bill or a humid house.
That’s why we use the blower door test as part of a complete energy audit, looking at your home and your AC system together.
A leaky, humid house isn’t “just Florida.” It can be measured, and it can be fixed.
Leaks make your AC cool and dry outside air all day long.
Humid outside air sneaking in can keep indoor humidity high.
Leaks can pull in air from the attic, walls and garage.
A leaky room can fight your AC no matter how low you set it.
How leaky your home is affects what size system it needs.
Testing again proves the work actually made a difference.
Simple, safe and done while you’re home.
We set up the blower door and measure how much outside air your home is letting in.
We walk your home to track down the leaks that matter most, including the ones you can’t see.
You get the results in plain language, with what to fix first and what it will do for you.
After the leaks are sealed, we test again so you can see the difference in writing.
Look up FL HVAC Services on Google and you’ll see a line most AC companies don’t have: “Home energy auditing recognized by the US Dept. of Energy.” Tap it and the Energy Skilled badge pops up, with a link to Energy.gov.
Nobody can add that to a business listing themselves. Not us, and not a marketing company. The U.S. Department of Energy verifies the credential and reports it to Google, and Google puts it on the listing.
What it means for your home: we look at your house and your AC as one system. How outside air leaks in, how humidity builds up, how air moves from room to room, and why some homes end up with stale, stuffy air that makes people feel worse inside than out. Then we design and fix your system for what your home actually needs.

It’s a test that measures how much outside air leaks into your home. A calibrated fan is set up in an outside doorway to change the air pressure inside, and we measure how much air comes in through cracks and gaps. Then we find where it’s coming in.
No. The test gently changes the air pressure in your home. Nothing is damaged, and you can stay home while we do it.
It can help, and it can make your home less humid and less dusty. But in most Florida homes, the biggest waste is the AC system itself. That’s why we look at both.
Yes. How leaky your home is affects what size system it needs. Testing first helps make sure your new AC is sized for your home, not guessed.
