Environmental Test & Balance Co., LLC

Environmental Test & Balance Co., LLC, a for-profit limited liability partnership based in Memphis, Tennessee, provides HVAC testing, isolation room certification, pharmacy inspection, fume hood recertification, and laboratory hood testing services to federal healthcare and research facilities as a prime contractor, competing exclusively in full-and-open procurements with no small business set-aside posture on the majority of its work — though recent awards have included Total Small Business set-asides.

The vendor's customer concentration is heavily concentrated with a single agency. The Department of Veterans Affairs Veterans Integrated Service Network 9 accounts for 22 of 32 awards (81% of award count) and $2.7 million of $3.5 million combined potential value (77% of dollars). The General Services Administration (GSA Federal Acquisition Service), the Department of the Army Corps of Engineers, and the Defense Finance and Accounting Service round out the active customer set, but VISN 9 represents the dominant revenue driver. Environmental Test & Balance holds a single-award Blanket Purchase Agreement with VISN 9 valued at $150,000 through September 30, 2028, for isolation room certification and related facility testing services at Memphis VA Medical Center and subordinate VA facilities in the region. Under this BPA, the vendor has issued three calls: $25,240 (October 2023–September 2024), $26,000 (October 2024–September 2025), and $26,780 (October 2025–September 2026). Representative recent work includes a $784,040 Total Small Business purchase order awarded October 1, 2025, for pharmacy inspection services at the Lt. Col. Luke Weathers, Jr. VA Medical Center (completion September 30, 2030); a $185,270 Total Small Business purchase order issued June 4, 2024, by the Army Corps of Engineers for fume hood and biosafety hood recertification at the Engineer Research and Development Center in Vicksburg, Mississippi (through December 3, 2029); and a $39,120 firm fixed-price purchase order from VISN 9 issued February 2, 2026, for HVAC testing and balancing services (completion March 31, 2026).

Activity has remained flat at two awards per year over the past five years, with one award in 2026 (source date). The vendor faces minimal recompete pressure in the next twenty-four months: only two awards with combined potential value of $109 thousand complete within that window. The vendor operates exclusively as a prime contractor (100% of awards); Service Contract Inventory data captures three prime records above the $150,000 federal service contract threshold, with $7 thousand in invoiced revenue and 0.1 FTEs reported in FY2023 — SCI's footprint is minimal and does not reflect the vendor's full federal services activity, which skews toward purchase orders and BPA calls below the SCI reporting floor. Median government-paid rates on SCI-reportable contracts run $59.17 per hour. Environmental Test & Balance has not engaged named subcontractors on recorded awards.

ET&B was founded in 1982 by Walter Green, TBE and Charles Fant, TBE, PE. Walt was one of the pioneers of the industry, beginning his test and balance career in 1968 when the field of testing and balancing was in its adolescence. Chuck Fant was a professional mechanical engineer who had a long history of mechanical system design and over 30 years experience in the test and balance industry. A partnership was formed with a mutual commitment to the betterment of the industry and HVAC performance. Our commitment to professional independent testing and balancing, customer satisfaction, and most of all honesty and integrity, is the key to our growth and success.
