National HVAC Services

National HVAC Services operates from a Memphis branch at 4105 Hickory Hill Road, serving the Mid-South region including the Memphis metro area and additional locations across Arkansas and Delaware. The contractor holds a 3.3-star rating from three customer reviews, providing commercial and industrial heating, cooling, and mechanical services to businesses across multiple sectors. Homeowners seeking HVAC support can reach the Memphis office directly at (901) 345-5700.

The contractor sets itself apart through its ThermaClear indoor air quality system, featuring advanced UV purification technology designed to neutralize airborne pathogens and improve circulation throughout built environments. Through a partnership with Service Logic, the company delivers coordinated mechanical services spanning multiple regions from coast to coast, a network advantage few regional contractors can match. Their portfolio extends across specialized verticals including mission-critical facilities, healthcare operations, research laboratories, and government properties, demonstrating expertise in complex environmental control demands that exceed standard commercial applications.

Customer feedback reflects polarized experiences. John Davis awarded five stars after the team assisted in restoring system functionality, describing the technicians as very helpful during a difficult situation. An opposing review from Zachary Lewis cited ongoing invoicing disputes following service cancellation, with unwanted visits and billing for work the customer believed was not authorized. These divergent accounts suggest service quality may vary depending on project scope and communication clarity.
