National Air & Energy

National Air & Energy is a family-owned mechanical contractor established in San Diego in 1995, holding nearly three decades of continuous operation in the region. Headquartered at 2053 Kurtz Street in the Midway District, the company maintains an aggregate rating of 3 stars across 22 customer reviews, reflecting a divided client experience that warrants careful consideration. While their primary focus serves commercial, industrial, and institutional markets rather than residential homeowners, their San Diego roots run deep, with direct presence in neighborhoods including Midway District, Point Loma, and North County.

What distinguishes National Air & Energy from regional competitors is their exclusive partnership with Siemens TALON as the San Diego area representative for building automation and controls products. This in-house Building Automation and Controls Department represents a specialized capability that few San Diego contractors offer, enabling integrated system design and monitoring for commercial properties. Their service portfolio spans comprehensive HVAC design, installation, preventative maintenance programs, and retrofit or ground-up construction projects including tenant improvements. The company positions itself around cost-sensitive mechanical solutions paired with what they describe as a commitment to customer care.

Customer experiences at this contractor reveal varied outcomes. Lauren Isaako described scheduling as super easy with technicians who were friendly, quick, and efficient enough to earn a recommendation. In contrast, Mark Kim detailed a frustrating commercial scenario at a mall location where the system failed repeatedly across three service calls, ultimately requiring a $5,000 replacement recommendation after spending $1,000 in diagnostics. Additionally, multiple reviews cited concerning driver behavior on San Diego roads, with drivers allegedly cutting off traffic, brake-checking other vehicles, and exceeding speed limits in residential zones.
