Eastern Air Balance

What Eastern Air Balance does

Eastern Air Balance Corporation is a privately held, independent testing, adjusting, and balancing (TAB) services firm incorporated in July 1965 and headquartered in Manheim, Pennsylvania. The company specializes in the measurement, calibration, and performance verification of air and hydronic flows within HVAC systems, duct leak testing (both commercial and residential), building systems commissioning, and laboratory fume hood certification testing. Service delivery is performed by NEBB-certified professionals and technicians using NIST-traceable instrumentation calibrated to NEBB procedural standards, supplemented by custom-constructed high-capacity duct leak test rigs (130 CFM to 1,000 CFM at up to 21" w.c.) that allow whole-system testing rather than sub-component testing.

The company's commercial model is a sales-led professional services operation. Engagements are executed under multi-year professional services contracts, with the firm brought in from the pre-construction design phase through final commissioning and owner training. It works directly with building owners, architects, engineers, and LEED-accredited professionals. Pricing is quote-based and not publicly disclosed, with billings tied to project and contract milestones.

Customer concentration is anchored in K-12 school districts across Central Pennsylvania (Wilson, Fleetwood, Oley Valley, Tulpehocken, Governor Mifflin, Chambersburg, and others) and in regional healthcare facilities anchored by Lancaster General Hospital and affiliated medical office buildings. Secondary verticals include higher education (Franklin & Marshall College), pharmaceutical, industrial manufacturing, and residential contractors requiring code-compliance duct leak testing under IEEC/IRC requirements. The firm maintains active leadership and standards-development roles across NEBB, ASHRAE, MAEBA, SMACNA, NEMI, and SMCA. The company has no disclosed institutional investors, no parent company, no subsidiaries, and no M&A or funding activity on record.

Products and services

• Air & Hydronic Systems Balancing Testing, adjusting, and balancing of air and hydronic (water-based) HVAC systems to ensure optimal performance, energy efficiency, and occupant comfort. Includes calibration of VAV systems, pneumatic, electronic, and DDC controls, with coordination with Automatic Temperature Controls contractors. Delivered under NEBB procedural standards by certified technicians.
• Building Systems Commissioning
• Duct Leak Testing (Commercial) Specialty service to identify and quantify air leakage in commercial HVAC duct systems. Uses custom test rigs (130-1,000 CFM capacity) to perform allowable duct leakage calculations based on SMACNA Seal Class and Leak Class Standards, providing certified test results for code compliance.
• Residential Duct Leak Testing Pressurized testing of residential HVAC duct systems as mandated by the International Energy Efficiency Code (IEEC) and International Residential Code (IRC). Includes rough-in tests (before air handler installation) and system tests (with air handler), measuring CFM per 100 square feet of conditioned living area against code allowable limits (4 CFM rough-in; 6 CFM system test).
• Fume Hood Testing Certification testing of laboratory fume hoods following NEBB procedural standards. Identifies operational deficiencies in fume hood and exhaust systems for schools, universities, hospitals, and pharmaceutical companies to ensure safety and regulatory compliance.

Quantifiable outcome

• Over 80% of homes studied were found to have duct sealing quality problems; average leakage rate of 21.6% of system flow in tested homes
