HVAC Project and Retrofit Work involves the design, installation, upgrade, or replacement of heating, ventilation, and air conditioning (HVAC) systems to improve energy efficiency, performance, and indoor air quality in residential, commercial, or industrial settings. For new projects, it includes the complete design and implementation of HVAC systems tailored to the specific needs of the building, ensuring proper heating, cooling, and ventilation for optimal comfort and energy efficiency.

Retrofit work, on the other hand, focuses on modernizing existing HVAC systems by integrating advanced technologies such as energy-efficient components, smart controls, or eco-friendly refrigerants.
