COOLING & HEATING UNLIMITED INC

COOLING & HEATING UNLIMITED INC specializes in the installation, maintenance, and repair of commercial and institutional HVAC systems, leveraging deep expertise in mechanical system integration, refrigerant handling, and energy-efficient climate control solutions. The company’s technical capabilities encompass ductwork fabrication, boiler and chiller servicing, thermostat and building automation system calibration, and compliance with ASHRAE and IECC standards. Their work focuses on ensuring operational reliability and thermal comfort in government facilities through preventive maintenance protocols, retrocommissioning, and system optimization tailored to facility-specific load profiles. A key differentiator is their hands-on proficiency in troubleshooting complex hydronic and air-side systems under demanding environmental conditions, particularly in cold-climate infrastructure. Award history does not provide sufficient detail to identify specific agencies or project types, so no direct agency relationships can be confirmed. However, given their NAICS classification and location, it is reasonable to infer engagement with federal, state, and local entities requiring facility services in North Dakota and surrounding regions, particularly in public buildings, military installations, and correctional facilities where climate control is mission-critical. The contractor operates under NAICS 238220, which corresponds to HVAC installation and repair services. In practice, this means they deliver turnkey mechanical system solutions for new construction and existing building retrofits, with an emphasis on code-compliant, long-life installations. Their market positioning centers on reliable, on-site service delivery rather than design-build or engineering consultancy, distinguishing them from firms offering broader systems integration. COOLING & HEATING UNLIMITED INC is a small, locally owned business structured as a 2L entity, indicating it is a limited liability company with no federal certifications on record. The company maintains its primary operational base in Bismarck, North Dakota, and serves regional government and institutional clients with a focus on practical, durable HVAC solutions suited to the Northern Plains climate.
