Their ability to execute complex, multi-disciplinary tasks—from HVAC manufacturing to shipboard maintenance and automotive engine rebuilds—reflects a nimble, hands-on operational model with strong attention to material specifications like ASTM A588 and precise mechanical integration. The contractor maintains consistent engagement with the Department of Defense, Department of the Interior, and Department of Agriculture, delivering mission-critical infrastructure support such as HVAC upgrades at national wildlife refuges, maintenance of fire response vehicles, and facility repairs at remote military bases. They also serve the Department of Energy with specialized equipment manufacturing and the Department of Homeland Security on vessel maintenance tasks, indicating a pattern of supporting operational readiness across land, sea, and remote federal sites. Their industry focus centers on plumbing, heating, and air-conditioning contracting (NAICS 238220), with significant activity in commercial HVAC equipment manufacturing (333415) and construction machinery leasing (532412). This positions them as a hybrid service-provider with both installation and equipment supply capabilities, serving federal facilities requiring integrated mechanical and infrastructure solutions. MayoInTheMix LLC is a small, 2L-structured firm based in Upper Marlboro, Maryland, with no federal certifications on record. Their geographic presence is defined by project-based deployments across federal installations nationwide, particularly in rural and remote locations requiring responsive, multi-trade technical support.
