If you’re reading this the night before your final inspection, or even the morning of, I want you to know one thing:
You’re not out of time.
At Middle Tennessee Blower Door, we’ve built our reputation on being there when others can’t.
I’m Chris Lewis, the guy who started this company with a blower door fan, a mission to make home efficiency simple, and a deep understanding of what it’s like to juggle building deadlines, real estate transactions, and changing energy codes.
Over the past few years, I’ve seen one scenario again and again:
The inspection is coming fast.
The house needs a blower door test.
No one’s available, or worse, the last guy bailed.
That’s where we step in. And this post is here to break it all down, how the test works, why it matters, and how we help homeowners, builders, and realtors in Middle Tennessee get it done right, even on tight timelines.
In short, a blower door test measures how “leaky” your home is—how much air is escaping through cracks, gaps, and poorly sealed areas.
It’s done by installing a powerful fan in your front doorway, depressurizing the house, and then measuring how quickly air rushes in from the outside. It gives us a reading of air changes per hour (ACH50), which tells inspectors and energy code officials whether the home meets efficiency standards.
In most Tennessee counties, especially Middle Tennessee cities like Nashville, Franklin, Murfreesboro, and Hendersonville, blower door testing is now required as part of the energy code compliance for new homes, major renovations, and home sales.
If your house is leaking too much air, it won’t pass inspection.
If you’re a builder, contractor, or realtor, you know how quickly things pile up toward the end of a project:
The drywall goes up late.
The HVAC guys were a no-show.
The appraisal date moved.
The buyer’s inspector wants confirmation of energy code compliance.
Suddenly, everyone’s looking at you for answers.
I’ve had homeowners call me in full panic mode the night before closing. Builders have texted at 5:45 a.m. asking if we can “get there before the county inspector shows up at 8.”
And you know what? More often than not, we make it happen.
We prioritize last-minute availability because we know the pressure. No one should lose a deal over an air pressure reading.
Here’s what to expect when we arrive:
Setup (10–15 minutes): We install the blower door fan system into your front door and prep our equipment.
Depressurization Test (5–10 minutes): We run the test, pulling air out of the house and gathering data.
Readings and Walkthrough (10 minutes): We show you the numbers, point out any problem areas, and explain what to do if the house doesn’t meet the ACH50 target.
Certificate Issued (Immediately): We email or hand-deliver your test results and certificate—often required by local code officials.
Total time: Usually 30–45 minutes.
And yes—we’ll text or call your inspector, builder, or buyer’s agent if needed to confirm documentation was submitted.
We’ve served hundreds of clients across Middle Tennessee, from small starter homes to luxury custom builds to historic properties undergoing renovation. Our clients include:
Homeowners prepping to sell
Real estate agents needing a quick turnaround
General contractors trying to hit deadlines
Energy efficiency consultants looking for reliable testing partners
They choose us not just for the test, but for how we show up.
First, don’t panic. It happens.
If your home fails the blower door test (ACH50 is too high), we immediately help identify the issue—often it’s an attic hatch, leaky door seals, missing caulk, or HVAC duct leakage.
We provide:
Photos or notes on problem areas
Quick-fix recommendations you or your contractor can handle
Follow-up retesting (we offer discounted same-day re-tests if needed)
We’re not here to fail people, we’re here to help you pass, without the stress.
If you’re a listing agent or buyer’s agent, adding a blower door test to your pre-listing checklist can be a game changer.
Why?
Faster closings: Avoid delays during inspections or appraisals
More transparency: Buyers love seeing proof of energy efficiency
Added value: Sellers can use the certificate as a marketing point
We work with real estate teams in Nashville, Brentwood, Smyrna, and beyond to handle blower door testing as part of their closing process, and we make it seamless.
You send the address. We handle the rest.
Middle Tennessee Blower Door was built on one core belief:
No one should lose a sale or fail an inspection because someone couldn’t show up.
We answer our phones early. We respond to texts late. We hustle to your job site even when the van’s barely cooled off from the last one.
We’re not a national chain. We’re not a faceless testing lab.
We’re locals. We’re neighbors. We’re pros. And we deliver under pressure, literally.
If you need a blower door test in the next 24–48 hours, or you just want to knock it out early before closing, text or call me directly.
