New England's HVAC TAB Specialists Since 1999
From hospital clean rooms to university laboratories, The THB Company delivers TABB and NEMI member TAB services across New England — air, water, fire, and everything in between.
Who We Are
The THB Company is an owner-operated, TABB testing, adjusting and balancing firm serving hospitals, research institutions, universities, and commercial facilities across all of New England.
Since 1999, we've built a reputation for precision, accountability, and deep technical expertise — including specialization in Class 1 clean rooms and FGI-compliant healthcare environments. We don't subcontract. Every project is handled by our certified team with state-of-the-art diagnostic equipment and real-time cloud-connected data reporting.
We've also helped author industry-standard publications — because we don't just follow the standards, we help shape them.
Learn About THBWhy Choose THB
Our dual certification means we meet the highest national standards for both air and water balancing, fire and life safety testing, and indoor air quality — credentials that most local TAB firms simply don't hold.
Our technicians are connected to our cloud platform in real time. Every reading, adjustment, and balancing record is documented live — giving you an accurate, auditable report the moment the job is done.
THB has contributed to the authorship of industry-standard publications. We don't just follow best practices — we help define them. That knowledge is applied to every project we take on.
We specialize in the testing and adjustment of Class 1 clean rooms — precision work that demands exactness beyond standard HVAC TAB. Pharma, biotech, and research clients trust us for this reason.
Since 1999 we have pursued environmental responsibility and energy conservation. We've been a leader in the implementation of Boston's Green Building Initiative and support LEED-certified projects.
