How is commercial HVAC different from residential?

Commercial HVAC systems are designed to meet the needs of larger, more complex buildings than residential systems. Commercial systems are typically larger in size and more powerful, allowing them to provide more efficient heating and cooling for larger spaces. Additionally, commercial systems often include more advanced features such as zoning, humidity control, and air filtration. These features are not typically found in residential systems. Commercial systems also require more frequent maintenance and servicing due to their larger size and complexity. This is to ensure that the system is running efficiently and safely.
