Service and Maintenance Solutions across South Carolina
At OSS Contracting, we believe that a successful construction project doesn’t end with installation—it continues through the life of the system. That’s why we offer ongoing service and maintenance solutions for all the major systems we install and support. Our team is equipped to maintain the mechanical, electrical, and plumbing infrastructure of residential, commercial, public, and healthcare buildings.
HVAC Service and Maintenance
Maintaining a building’s heating, ventilation, and air conditioning system is critical to occupant comfort and energy efficiency. Our experienced technicians provide scheduled HVAC maintenance, cleaning, and performance testing for systems installed in homes, schools, offices, car dealerships, and medical centers. We ensure filters are clean, ductwork is sealed, refrigerant levels are balanced, and all equipment operates as it should—even in the peak of summer or the coldest days of winter.
We also specialize in servicing energy-efficient and smart HVAC systems, offering repairs, upgrades, and preventative checks that extend system life and reduce operational costs. Our responsive team is available for emergency breakdowns and complex repairs, ensuring your heating and cooling never miss a beat.
Electrical System Maintenance
Electrical infrastructure must be inspected and maintained to ensure safety, reliability, and compliance with ever-evolving building codes. OSS Contracting provides full electrical service and maintenance for both high-voltage and low-voltage systems in residential, commercial, public, and healthcare environments.
Our services include testing panel boards, circuit protection, lighting systems, emergency power systems, and integrated automation setups. We make sure your building’s electrical infrastructure operates efficiently while meeting state and national code requirements. With decades of combined field experience, our electricians handle everything from minor wiring issues to ongoing service contracts for large public or institutional buildings.
Plumbing Maintenance and Repairs
OSS Contracting offers reliable plumbing service and maintenance programs for everything from custom homes and healthcare facilities to public buildings and retail centers. Our licensed plumbing team inspects water supply systems, drainage lines, fixtures, valves, and heating components to ensure consistent flow and code compliance.
Regular maintenance helps prevent major issues such as backups, leaks, and corrosion—problems that can disrupt business operations or compromise indoor hygiene. Whether you’re running a medical facility that needs sterile water delivery or a home with advanced water heating systems, we maintain plumbing infrastructure to the highest performance and cleanliness standards. Our emergency response team is available to handle urgent repairs quickly and professionally.
Maintenance Services for Healthcare and Public Infrastructure
Healthcare environments and public facilities depend on fully functioning MEP systems every day. OSS Contracting offers dedicated service contracts and customized maintenance schedules to support these essential environments. In hospitals, outpatient clinics, schools, and municipal buildings, we provide regular system reviews, inspections, and immediate troubleshooting to ensure regulatory compliance and uninterrupted functionality.
Because these buildings often operate 24/7 or host high foot traffic, we tailor our maintenance services to minimize disruption, coordinating with your schedules and maintaining transparent communication every step of the way.
Long-Term Performance with Professional MEP Contractors
As experienced MEP contractors, OSS Contracting offers integrated maintenance services across the Mechanical, Electrical, and Plumbing (MEP) disciplines. This combined service approach allows us to streamline inspection schedules, identify system interdependencies, and resolve issues holistically—ensuring your entire building infrastructure works together efficiently.
With one point of contact for all MEP servicing needs, our clients experience fewer delays, more accurate diagnostics, and better coordination across building systems. Whether your project is residential, commercial, or public-sector, our ongoing MEP service and maintenance work is designed to preserve your building’s value, safety, and comfort.
