With over 8 years of HVAC engineering experience, including several years as a full-time HVAC Design Engineer, I specialize in designing efficient, code-compliant heating, ventilation, and air conditioning systems for residential, commercial, and light industrial projects. My expertise covers Manual J, Manual D, and Manual S, cooling and heating load calculations, duct design, ventilation systems, airflow balancing, equipment sizing, heat gain and heat loss analysis, energy-efficient HVAC solutions, and mechanical construction documentation using AutoCAD and Revit MEP. Having worked both in the office and in the field, I understand not only the engineering principles behind HVAC design but also the practical challenges encountered during installation. This hands-on experience enables me to create accurate, buildable, and permit-ready designs that reduce costly revisions, improve installation efficiency, and ensure compliance with applicable codes and industry standards. As a freelance HVAC engineer, I combine professional industry expertise with personalized service, fast turnaround, and clear communication. I am committed to delivering precise calculations, reliable documentation, and high-quality HVAC designs that maximize comfort, energy efficiency, and long-term system performance while helping clients complete their projects with confidence.
