How soon can you schedule a blower door test in Middle Tennessee? Most testing companies book out weeks in advance. At Middle Tennessee Blower Door, we can typically get you on the schedule within the week, and in many cases within 24 to 48 hours of your call.
That difference matters when your closing is Thursday, the inspector needs documentation by Friday, or you just discovered your HVAC install is complete and the permit clock is ticking.
Construction schedules rarely go according to plan. The drywall crew finishes early. The HVAC inspection gets moved up. The buyer's lender adds a last-minute requirement. When you need code compliance documentation, you need it now, not in two weeks.
A single day of delay can cascade into missed inspections, pushed closings, and frustrated buyers. That is why we built our entire operation around builder timelines, not ours.
Several factors determine how quickly we can get to your job site. Location plays a role. We serve all of Middle Tennessee from our Gallatin base, including Nashville, Franklin, Murfreesboro, Hendersonville, Mt. Juliet, and surrounding counties. Jobs closer to our regular routes can often be scheduled faster.
Project readiness also matters. For accurate blower door results, all exterior doors and windows must be installed and closed. Fireplace dampers need to be shut. Any large penetrations in the building envelope should be sealed or temporarily covered. When you call, we will walk through a quick checklist to confirm your home is ready for testing.
Seasonal demand fluctuates throughout the year. Spring and fall tend to be peak construction seasons in Middle Tennessee, with more builders pushing to close before summer heat or winter holidays. Even during busy periods, we prioritize same-day availability because we understand that your schedule does not pause for ours.
A typical blower door test takes 30 to 60 minutes on site. We install a calibrated fan system in an exterior doorway, then depressurize the home to 50 Pascals, the standard pressure differential used to measure air leakage. The results are expressed in ACH50, which stands for air changes per hour at 50 Pascals of pressure.
Under IECC 2018 requirements, homes in Tennessee's climate zone must achieve an ACH50 of 3.0 or lower to pass code compliance. We provide detailed documentation of your results, including any problem areas identified during testing. If a home does not pass, we can often pinpoint the leakage sources and advise on remediation before you bring in the trades for corrections.
You will know whether your home passed before we leave the job site. We provide same-day documentation for code compliance purposes, formatted for submission to building departments and inspectors across Davidson, Williamson, Rutherford, Sumner, Wilson, and surrounding counties. No waiting days for a report to arrive. No follow-up calls required.
Owner Chris Lewis brings over 20 years of construction experience to every test. That background means we understand the pressure you are under and the stakes involved when a project hangs on a single inspection. We are RESNET certified, so your results carry the credibility that inspectors and lenders expect.
Beyond the credentials, we have built our reputation on reliability. When we say we will be there, we show up. When we say you will have results today, you will have them. That is why builders across Nashville, Franklin, Murfreesboro, and throughout Middle Tennessee keep our number saved and ready.
Cold snaps like we see in February actually create ideal conditions for identifying air leakage. When there is a significant temperature differential between inside and outside, thermal imaging can reveal exactly where conditioned air escapes and unconditioned air infiltrates. If you are testing during a cold stretch, we can often provide more detailed diagnostic information about your building envelope's performance.
Wind conditions can affect testing accuracy, so we may need to reschedule if sustained winds exceed certain thresholds. We monitor conditions and will communicate proactively if weather might impact your scheduled test.
