14 Mechanical Decommissioning Services in Nassau County

Heating & Fuel Systems
Boiler Removal
United Decommission provides end-to-end boiler removal services for commercial properties, industrial plants, schools, and residential complexes. Our experienced rigging crews specialize in dismantling and extracting heavy sectional cast iron boilers, scotch marine steel boilers, and high-pressure steam vessels from difficult-access mechanical rooms and basements. We handle the complete process: utility lock-out/tag-out, cold cutting, heavy hydraulic rigging, debris removal, and all required municipal building and environmental permits.
Heating & Fuel Systems
Boiler Decommissioning
Boiler decommissioning requires strict engineering oversight to permanently retire or safely mothball commercial heating plants. United Decommission performs systematic gas line purging with inert nitrogen, fuel oil line drainage and blanking, hydronic system draining, boiler vessel chemical passivation, and mechanical system isolation. We eliminate regulatory exposure and building department violations while preparing facilities for heat pump conversions, building redevelopment, or full property disposition.
Heating & Fuel Systems
Oil Tank Removal
Old or decommissioned heating oil tanks present significant environmental liability and property transaction obstacles. United Decommission delivers comprehensive aboveground (AST) and underground (UST) fuel storage tank removals for commercial facilities, industrial yards, and residential estates. We manage vacuum pumping of remaining fuel oil and bottom sludge, confined space tank cleaning, sparkless cold cutting or excavation, soil screening, backfilling, and state environmental closure filings.
Heating & Fuel Systems
Oil Tank Decommissioning
When underground or vault-enclosed fuel storage tanks cannot be physically excavated due to adjacent foundations, structural footings, or active utility corridors, in-place decommissioning is the engineered solution. United Decommission executes certified tank abandonment: accessing the vessel, pumping out all fuel and sludge, hydro-cleaning interior walls, testing for clean atmosphere, and pressure-filling the tank with inert concrete slurry or structural polyurethane foam per local fire code.
Climate Control Systems
HVAC Removal
United Decommission is the premier mechanical removal partner for commercial HVAC retrofits, facility redevelopments, and warehouse upgrades. We manage the safe removal of packaged rooftop units (RTUs), custom air handling units (AHUs), variable refrigerant flow (VRF) systems, and cooling towers. Our crews handle EPA Section 608 certified refrigerant recovery, crane rigging, roof curb flashing coordination, electrical and gas disconnects, and certified scrap recycling.
Climate Control Systems
HVAC Decommissioning
Proper HVAC decommissioning ensures that mechanical plants are safely de-energized, environmental liabilities are neutralized, and equipment is properly logged for asset recovery or capital write-downs. United Decommission works with building owners, general contractors, and corporate tenants to systematically decommission central HVAC plants, packaged rooftop fleets, and multi-zone VRF systems, providing complete chain-of-custody documentation and clean mechanical room handoffs.
Climate Control Systems
AC / Air Conditioner Removal
Whether upgrading to high-efficiency heat pumps or clearing rooftop space for commercial solar installations, United Decommission provides rapid, certified air conditioner removal. We service commercial buildings, residential developments, and retail strip centers across the Tri-State area. Our crews recover all refrigerant safely, disconnect electrical disconnects, sever copper line-sets, and haul away old condensing units and evaporator coils for recycling.
Climate Control Systems
AC / Air Conditioner Decommissioning
Decommissioning commercial air conditioning systems requires strict environmental compliance under EPA Title VI of the Clean Air Act. United Decommission provides certified AC decommissioning for commercial facilities undergoing renovations, tenant fit-outs, or demolition. We perform deep-vacuum freon recovery, system de-pressurization, electrical safe-off, and supply complete documentation verifying that all ozone-depleting substances (ODS) and greenhouse gases have been legally recovered.
Industrial Cooling Systems
Chiller Removal
Industrial chiller removal is a high-stakes mechanical rigging operation requiring specialized engineering, heavy crane equipment, and rigorous environmental compliance. United Decommission specializes in the extraction of 50-ton to 1,500-ton water-cooled centrifugal chillers, air-cooled screw chillers, and absorption chillers. We manage complex basement extractions using heavy modular gantries, penthouse crane picks with street permits, oil and refrigerant pumping, and certified asset salvage.
Industrial Cooling Systems
Chiller Decommissioning
Decommissioning large-tonnage commercial and industrial chillers demands exacting technical expertise to mitigate severe environmental liabilities. United Decommission executes certified chiller decommissioning for data centers, hospitals, corporate campuses, and district energy plants. We handle high-volume liquid/vapor refrigerant recovery, vacuum dehydration, compressor lubricating oil drainage and recycling, chilled water and glycol loop flushing, and formal regulatory closeouts.
Refrigeration Systems
Commercial Refrigeration Removal
Commercial refrigeration removal demands rapid turnaround and meticulous environmental controls. United Decommission supports supermarket chains, food processing plants, cold-storage logistics warehouses, and hospitality facilities with turnkey refrigeration removal. We dismantle parallel compressor racks, walk-in coolers and freezers, rooftop condensers, and retail display cases while adhering to EPA Section 608 refrigerant recovery mandates.
Refrigeration Systems
Commercial Refrigeration Decommissioning
Closing a supermarket, cold-storage distribution center, or institutional food service facility requires formal commercial refrigeration decommissioning to eliminate ongoing tenant liability and EPA penalties. United Decommission provides turnkey decommissioning services: safely reclaiming multi-circuit refrigerant charges, draining and recovering synthetic compressor oils, purging secondary glycol chill loops, and certifying safe mechanical de-energization for commercial property surrender.
Refrigeration Systems
Refrigerator Removal
United Decommission provides rapid commercial refrigerator removal for restaurants, grocery stores, corporate cafeterias, bakeries, and medical clinics. Whether disposing of broken reach-in coolers, glass-door display refrigerators, sandwich prep tables, or commercial undercounter units, our mobile crews handle EPA Section 608 freon evacuation, careful removal without damaging finished floors or door frames, and environmentally responsible metal recycling.
Refrigeration Systems
Refrigerator Decommissioning
Proper commercial refrigerator decommissioning ensures that appliances are legally certified as hazard-free prior to property transfer, scrap auction, or municipal disposal. United Decommission performs systematic decommissioning of commercial refrigerators, reach-in freezers, and specialty laboratory cold units. We evacuate all refrigerant to federal vacuum levels, recover compressor oil, tag each appliance with EPA compliance certification labels, and deliver audit logs.
