Emergency HVAC Services in Fresno, CA 93703 - Lawson Mechanical Contractors

Our process starts with a detailed pre-construction and energy analysis specific to your Fresno building's needs. We then use our advanced in-house BIM/CAD planning to design the system and identify any potential installation conflicts early. Components are custom-fabricated in our local facilities, allowing for precise, efficient on-site assembly. This method, honed since 1947, ensures the project stays on schedule and the system is built for the Valley's climate and your long-term operational efficiency.

Absolutely. We specialize in diagnosing and repairing commercial HVAC systems to restore performance and efficiency. Our technicians are trained to troubleshoot complex industrial equipment. Often, inefficiency stems from issues within the ductwork or piping systems—areas where our custom fabrication expertise allows us to manufacture precise replacement parts on-site for a lasting repair that fits your existing setup perfectly.

These are common issues in our climate. First, ensure your smart thermostat is correctly configured for your heat pump's specific mode (heating vs. cooling), as improper settings are a frequent culprit. For efficiency loss, it's often due to dirty coils, refrigerant issues, or airflow problems exacerbated by Valley dust. We recommend a professional maintenance check. While we specialize in commercial systems, our deep understanding of HVAC mechanics from large projects gives us insight into all system types, and we can refer you to trusted residential specialists for hands-on help.
