About H & H Mechanical Corporation
H & H Mechanical Corporation, a small business HVAC contractor based in Austell, Georgia, operates exclusively as a prime contractor delivering heating, ventilation, and air-conditioning repair, maintenance, installation, and equipment rental services to the National Park Service. The vendor competes entirely under Total Small Business set-asides and holds no federal contract vehicles, IDIQs, or blanket purchase agreements.
H & H Mechanical's federal footprint is narrow and concentrated. All seven awards in the source data originate from the National Park Service Southeast Region, representing the vendor's only federal customer. Combined potential value across the award portfolio is $119 thousand, fully obligated; the vendor operates at the micro-contract scale typical of regional maintenance and repair work. Representative prime work includes a $52.8 thousand firm fixed-price purchase order (March 2024) for initial commissioning, inspection, preventive maintenance, and as-needed HVAC service at multiple NPS buildings including a visitor center and historic sites; a $28.9 thousand purchase order (December 2024) for temporary boiler rental, removal and disposal of an existing 500K BTU boiler, and plumbing work at a visitor center in Luther, Iowa; and a $13.9 thousand purchase order (April 2022) for HVAC maintenance and repair at the Martin Luther King Jr. National Historic Site. Additional awards involve HVAC replacement for energy efficiency upgrades and repair work at Kennesaw Mountain National Battlefield Park.
Award activity is sparse and episodic: two awards in 2021, two in 2022, none in 2023, two in 2024, and one in 2026. The vendor faces one recompete within the next twenty-four months (combined potential value $4 thousand). The source characterizes H & H Mechanical as having a strong track record with NPS Southeast Region in maintenance, repair, replacement, and installation projects for federal facility infrastructure, but the vendor has not diversified beyond a single agency or geographic region and carries no subcontract relationships or parent-vehicle positions that would create downstream opportunity for partners or competitors.
