Transparent Pricing for Tested Home Performance Solutions

Our consultations are complimentary and designed to help homeowners take the first step.

• Discovery calls to discuss goals, concerns, or comfort issues
• Professional guidance to help you understand options before committing to a full audit
• Referrals and resources tailored to your situation
  For those who already know what they’re looking for, we may also offer a:
• Virtual estimate, based on the information you provide (e.g., address, photos, and scope of work)
  • This option is ideal for homeowners who want to move quickly toward installation without unnecessary steps

• Blower Door Test: This test uses a calibrated fan to create a pressure difference across the home’s shell, measuring total air leakage — both infiltration (air entering) and exfiltration (air escaping). The results quantify how leaky the home is and help us prioritize air sealing measures.
  Unchecked leakage not only affects comfort and indoor air quality — it also contributes to unnecessary heating and cooling costs year-round.
• Zone-Specific Pressure Testing: By connecting the blower door's hoses to different zones, like attics, crawlspaces, and basements — we measure pressure differences between these areas and the outdoors. This helps pinpoint hidden air leaks within your home.
• Fog imaging: While thermal imaging helps us spot surface-level temperature differences, we often go a step further by fogging specific zones or entire homes. This technique makes hidden leakage points visible in real time and provides a dramatic, visual confirmation of air movement pathways. It's especially useful when validating pressure boundaries or explaining problems to homeowners.
• HVAC Ductwork Pressure Mapping: We often include pressure panning to map duct leakage and locate hidden return or supply losses. This test, combined with blower door pressure, helps identify air being pulled through wall chases, floor cavities, or disconnected ducts — issues that waste energy and reduce comfort.
• Combustion Appliance Zone (CAZ): This testing should be included when homes have gas water heaters, furnaces, or boilers. This safety check ensures your appliances have adequate air supply to vent properly — especially important before air sealing or insulation work that could alter airflow.

Yes — after your audit, we generate a proprietary, cloud-based energy report that reflects your home's diagnostic test results and retrofit potential. It’s not boilerplate — it’s built around what we verify onsite, secured with a private password, and remains non-static so it can evolve with your project as upgrades are completed.

This standalone service is often required for new homes, major renovations, or to meet Pennsylvania energy code compliance (typically 3 ACH50 or better). We provide testing for builders, HVAC contractors, architects, and homeowners needing fast, accurate results and certification.

Our testing includes:

• Envelope tightness verification using calibrated blower door equipment
• Detailed reporting with ACH50 calculations, pass/fail status, and corrective guidance
• Flexible scheduling, including evenings and weekends when weather permits
• Optional re-test discounts if additional sealing is needed prior to final signoff
• PASS Option (Pressure-Assisted Sealing Service) ~For homes that don’t meet the target, we can quickly diagnose and deliver targeted air sealing using live blower door feedback and specialized equipment — helping you reach compliance the same day without rescheduling.

Yes. The sealant is non-toxic, water-based, and rated ultra low VOC. It's been tested and used in hospitals, schools, and thousands of homes. Most families remain home during the sealing process. As a precaution, Project Probono may recommend that infants or immunocompromised individuals step out for the day.

Aeroseal’s duct sealant comes with a 10-year warranty, but laboratory and field testing show performance lasting well over 20 years. Unlike tape or mastic, it seals from within the duct system, where it can’t peel or degrade from surface exposure.

In most cases, duct cleaning is not necessary. However, if your ductwork contains loose debris, visible mold, or heavy buildup, we may recommend cleaning before sealing. Project Probono will evaluate your system beforehand and let you know if prep work is needed. 

Aeroseal is engineered to seal gaps up to ⅝ inch wide. If we find larger holes, disconnected ducts, or crushed runs, we’ll perform manual repairs first — and then complete the sealing from the inside. This two-step approach ensures full-system restoration.

No — and that’s a good thing. Aeroseal only seals the leaks, not the whole duct interior. The sealant particles stay airborne inside the system until they’re pulled through leak points — where they accumulate and close gaps. The rest of the duct walls stay clean and uncoated.

According to field studies, duct sealing can reduce HVAC energy use by 20–40%, especially in Pennsylvania homes with leaky return ducts or second-floor comfort issues. Some homeowners report saving up to $850 per year, depending on your system, the envelope and energy usage.

Yes — and there's no comparison especially when ducts are hidden in walls, floors, or attics. Aeroseal reaches places manual sealing can’t, sealing the entire interior system from the inside out. Project Probono uses both methods when needed — manual for large repairs, and Aeroseal to finish the job and verify results.

Yes. Every Aeroseal project includes pre- and post-sealing duct leakage testing, plus a digital Seal Certificate showing how much leakage was reduced — often by 90% or more. We also measure airflow improvement and can provide a blower door comparison upon request.
