National Air and Energy: Licensed HVAC Services Serving San Diego, CA 92110

As a fully integrated mechanical contractor since 1995, our process goes beyond just equipment swap. For commercial and institutional clients in San Diego, our in-house engineering staff first assesses your building's specific needs. We then handle the complete installation, which can include new ductwork, controls integration, and connection to our 24/7 monitoring service. With over 130 local employees, we manage the entire project from permitting to completion, ensuring your new HVAC system is optimized for both efficiency and the unique demands of our local climate.

We offer 24/7 emergency service for exactly this reason. When you call, our dispatcher will connect you with a local technician familiar with commercial systems. Common issues like capacitor or blower motor failures can often be diagnosed on-site. We maintain a extensive local parts inventory to facilitate same-day repairs for many problems, minimizing downtime for your San Diego business. Our goal is to restore your comfort as quickly and reliably as possible.

San Diego's extended cooling season means HVAC systems run constantly, putting significant stress on components like capacitors and blower motors. The sustained heat and electrical load can cause these parts to wear out prematurely. Our preventative maintenance plans are designed specifically for this local challenge. During a maintenance visit, our technicians will test these critical components for early signs of wear, clean the system to reduce strain, and recommend proactive replacements to avoid a costly emergency breakdown during a heatwave.
