Demystifying Commercial HVAC Units: A Comprehensive Guide

When it comes to HVAC (Heating, Ventilation, and Air Conditioning) systems for commercial buildings, the options can seem overwhelming. Each type of unit has its own set of advantages and is suited to different applications. At Package Unit Pros, we understand the importance of choosing the right HVAC system for your specific needs. In this blog, we'll demystify the different types of HVAC units commonly found in commercial buildings.

Packaged Units

Packaged HVAC units are all-in-one systems that contain both the heating and cooling components in a single cabinet. They are typically located outside or on the roof of the building. Packaged units are space-efficient and are often used in smaller commercial spaces, making them a cost-effective choice.

Split Systems

Split systems consist of two main components: an indoor air handler or furnace and an outdoor condenser unit. These systems are flexible and can be customized to suit the specific needs of your building. They are suitable for a wide range of commercial applications and offer efficient heating and cooling.

Rooftop Units

Rooftop HVAC units are installed on the roof of a building, offering a space-saving solution. They are commonly used in larger commercial buildings and provide efficient heating, cooling, and ventilation. Rooftop units are known for their ease of installation and maintenance.

Variable Refrigerant Flow (VRF) Systems

VRF systems are versatile and energy-efficient. They use refrigerant to heat or cool spaces and can provide precise temperature control in different zones of a building. VRF systems are ideal for large commercial buildings with varying occupancy needs.

Chilled Water Systems

Chilled water systems use water as a medium to transfer heat for cooling. They are often found in larger commercial buildings like office complexes and hotels. These systems are energy-efficient and can be highly reliable when well-maintained.

Heat Pumps

Heat pumps can both heat and cool spaces by transferring heat between the inside and outside of a building. They are efficient in moderate climates and are often used in commercial spaces seeking eco-friendly solutions.

Fan Coil Units

Fan coil units are smaller, individual units that are often used to supplement other HVAC systems. They are versatile and can be installed in various locations within a building, providing localized climate control.

Evaporative Coolers

Evaporative coolers, also known as swamp coolers, are an energy-efficient cooling option in dry climates. They work by evaporating water to cool the air. They are commonly used in commercial spaces like warehouses and factories.
