FAQs

What is commercial HVAC and how is it different from residential HVAC?

Commercial HVAC systems are designed for large-scale buildings like office towers, hospitals, schools, and industrial facilities. Unlike residential HVAC systems, which are simpler and designed for single-family homes, commercial systems must handle larger spaces, variable loads, and more complex ventilation requirements.
