Blower Door Testing in Palm Bay: An Owner-Builder Comes In at 2.55 ACH50

Blower door testing in Palm Bay with a Retrotec fan and panel installed in the doorway of an owner-built home

Stellar Building Performance recently completed blower door testing in Palm Bay at a new owner-built home in the Wichita Acres area, between the Emerson Drive and Babcock Street corridors near Bill Madden Park. This project came to us directly from the owner, who built the home with his wife as their retirement residence and did most of the work himself.

The call came in on a Friday morning. He needed envelope leakage testing to close out the build and move toward final inspection, and the timing was tight. We were able to coordinate with him and get onsite Saturday morning to complete the test.

A 2.55 ACH50 Result in Palm Bay

During testing, the home measured 740 CFM50 at the required 50-Pascal pressure difference. With a conditioned building volume of 17,410 cubic feet, that produced a final air leakage result of 2.55 ACH50.

ACH50 expresses the measured air leakage relative to the volume of the home, allowing the blower door result to account for differences in building size. It provides a standardized measurement of how much air moves through the building envelope under controlled test conditions.

This project was documented through the performance compliance path, and the energy calculation for this home specified a target of 3.0 ACH50. At 2.55, the envelope came in under that number with room to spare. Air leakage targets are project specific and depend on how the energy compliance was documented, so two homes on the same street can carry different numbers.

Saturday Testing When the Schedule Mattered

This is the part of the project I keep coming back to. The owner reached out Friday morning, and by Saturday morning I was onsite in Wichita Acres getting his testing taken care of.

We don’t advertise or guarantee weekend or same-day availability, because every week’s schedule is different. But when we have the ability to accommodate an urgent project, we’re going to do what we reasonably can to help somebody keep moving. A homeowner working to close out a build he had poured a year into was worth the trip.

Construction schedules have enough moving pieces already. When testing becomes one of those last-minute pieces, communication and responsiveness make the difference. You can see the same approach on a recent blower door test in Rockledge.

Builders and contractors with recurring projects can request a proposal for ongoing energy-code testing and building-performance support throughout Brevard County.

Mechanical Ventilation on a Tight Envelope

There is a second consequence to a result like 2.55, and it is one more Florida builders are going to run into.

Under the 2023 Florida Building Code, Energy Conservation, Eighth Edition, a dwelling testing below three air changes per hour requires whole house mechanical ventilation, and that installation has to be verified by the building department. A house that tight is no longer exchanging enough air on its own, so the fresh air has to be brought in deliberately.

This owner had already handled it. The home was set up with a supply ventilation system pulling outside air through a dedicated insulated duct tied into the air handler, with a motorized damper controlling when fresh air is introduced and how much comes in. It was installed cleanly and ready to be verified, which is exactly how you want to find it on test day.

We covered where this is heading in our breakdown of the 2026 Florida Building Code energy conservation changes. As homes continue to get tighter, envelope and ventilation are going to be two halves of the same conversation.

An Owner-Built Home in Wichita Acres

This project stood out because of who built it.

An owner-builder working on his own home has every reason to cut a corner where nobody is looking, and this one did not. The envelope was spray foamed, the detailing was consistent, the penetrations were addressed, and the result reflected it. Spray foam is one route to a number like this, though not the only one. We have tested homes with blown insulation and a vented attic that landed in strong territory because somebody took the ceiling plane air barrier seriously.

Wichita Acres sits in southeast Palm Bay, an established area where individual lots continue to fill in. It’s another good example of the variety we see in the field. Energy-code testing isn’t limited to large new subdivisions. We work on everything from owner-built and custom residences to production housing, multifamily developments, and larger recurring builder projects.

More Than a Test Result

A big part of doing this work well is making the process easy for the person managing the project, whether that’s a superintendent running six homes or an owner finishing the one he lives in.

For this Palm Bay home, that meant answering the phone Friday, making the schedule work Saturday, and getting him the documentation his closeout needed. That’s the standard we’re working toward on every project.

Stellar Building Performance provides blower door testing, duct leakage testing, HERS ratings, energy-code services, and third-party quality assurance throughout Brevard, Indian River, St. Lucie, Martin, and Okeechobee counties.

Mario with Stellar Building Performance came in clutch today. I was informed by the plans review department of SLC that I needed to complete a blower door test on my nearly finished new construction home. I got in touch with Mario, and he could not have been more professional. He answered all my questions and informed me he would be out the same day. He showed up on time and completed his test, explaining the process. When he finished, he issued my certificate on the spot. This was a great experience, and I would definitely recommend his services.

I cannot recommend Stellar Building Performance and the owner, Mario, enough! We purchased our 1993 home in Viera in mid-February, after having a thorough home inspection completed. When the first truly hot days of summer arrived, however, we realized our air conditioning system was struggling to keep up. An HVAC company we had used in the past told us it was not the system itself and suggested expensive work in the attic. But, before spending thousands of dollars, we wanted an unbiased opinion from someone who wasn’t trying to sell us equipment or additional services. That’s exactly what we found with Mario. He performed an incredibly thorough home energy audit that included a heat load and air leakage investigation, blower door testing with detailed notes and photos, duct leakage testing, infrared imaging, room-by-room pressure measurements, and comprehensive insulation inspections of both the walls and attic. More importantly, he took the time to explain verbally, and with a written report, what he was finding, why it mattered, and what improvements would provide the greatest benefit for our home. The report and recommendations were detailed, educational, and gave us the confidence to make informed decisions instead of simply accepting costly recommendations from contractors. What impressed me most was Mario’s integrity. He had nothing to sell us other than his expertise, which made his recommendations feel completely trustworthy. Even after the audit was finished, he continued checking in to see how things were going and what improvements we had made. That level of follow-up and genuine concern for his clients is rare today. If you’re experiencing high energy bills, uneven temperatures, an overworked HVAC system, or simply want to understand how your home is performing before investing in repairs, Stellar Building Performance is absolutely worth the very reasonable cost. Mario’s knowledge, professionalism, and commitment to helping homeowners make informed decisions exceeded every expectation.

If I could give 10 stars, I absolutely would. We had the pleasure of working with Mario from Stellar Building Performances, and the name of his company truly says it all, stellar from start to finish. Mario went completely above and beyond in every aspect. His attention to detail is on another level, and his communication throughout the entire process was clear, consistent, and professional. What really stood out was his willingness to go the extra mile, he didn’t just do the job, he made sure everything was done right. He even took the time to consult with building departments across multiple counties to ensure accuracy and compliance, which is something you rarely see. That level of dedication and care is hard to find. It’s rare to come across someone who is not only knowledgeable, but genuinely committed to helping and doing things the correct way. Mario is exactly that. We highly, highly recommend Stellar Building Performance to anyone looking for quality, professionalism, and someone who truly cares about their work.
