Air Balancing

Air Balancing US operates as a certified Testing, Adjusting and Air Balancing (TAB) professional company based in Philadelphia, Pennsylvania. The business holds a perfect 5.0-star rating drawn from six customer reviews, reflecting consistent satisfaction among both residential and commercial clients. Their service territory encompasses Pennsylvania, New Jersey, Delaware, and Maryland, positioning them as a regional specialist capable of handling multi-state HVAC projects. This contractor focuses exclusively on the technical discipline of air balancing rather than offering broad HVAC installation or replacement services.

What distinguishes Air Balancing US is their portfolio of specialized diagnostic services that most general HVAC contractors do not perform in-house. Their expertise spans hydronic balancing for water-based heating systems, duct leakage testing to identify energy-wasting leaks, stairwell pressurization testing for code compliance, and blower door testing for envelope air infiltration analysis. They also conduct home energy audits that uncover efficiency improvement opportunities beyond the HVAC system itself. The company provides same-day scheduling for urgent situations and delivers completed air balance reports within the same day of service, a timeline multiple reviewers confirmed.

Reviewers specifically mention working with Ori, describing the technician as professional and responsive during service delivery. One customer recounted scheduling an appointment that was accommodated far sooner than competing air balancing companies could offer, with the technician arriving on time and completing the HVAC system balance plus delivering the report on the same day. Another reviewer highlighted the company's rapid response for commercial HVAC systems, noting on-time arrival and fair pricing. The blower door test service in Philadelphia received specific mention from a reviewer who engaged the company for that diagnostic procedure.
