Choosing the right HVAC system for your building is a crucial decision that affects comfort, energy efficiency, and long-term costs. Two common options are packaged units and split systems, each with its own benefits and drawbacks, depending on the application. Understanding the differences can help you determine which system suits your needs best. In this blog, we’ll explore the key distinctions between these HVAC solutions, helping you make an informed choice for your space.
What Are Packaged Units?
Packaged units combine all the heating and cooling components into a single, compact system. These units are typically installed on rooftops or the ground near a building.
Advantages of Packaged Units:
- Space-Saving Design: Ideal for buildings with limited indoor space since all components are housed in one unit.
- Ease of Maintenance: With everything in one location, maintenance and repairs are more straightforward.
Disadvantages of Packaged Units:
- Redundancy: Oftentimes, many spaces are served by a single unit, which during failures, can mean more occupants are without conditioned air. However, larger packaged units usually have separate circuits, which will allow for partial conditioning to continue if only one circuit is not operational.
- Weather Exposure: Outdoor placement means ALL components are more exposed to weather-related wear and tear.
What Are Split Systems?
Split systems consist of the same components, except half are located inside a space (air handler) and the other half is located outside of the building (condenser). These systems are commonly used in residential applications as well as some commercial buildings.
Advantages of Split Systems:
- Flexibility: Split systems can allow for a cost effective means of zoning and customized temperature control in different areas without needing numerous VAV terminal units to be installed throughout the building, oftentimes also requiring a costly control system/BAS. This is not always the case, however, and you should always consult a professional contractor.
Disadvantages of Split Systems:
- Indoor Space Requirement: The indoor unit requires dedicated space for installation which for servicing the equipment, can be a nuisance for the occupants or in hard to reach places.
Key Differences Between Packaged Units and Split Systems
| Feature | Packaged Units | Split Systems |
| Design | All-in-one system | Separate indoor and outdoor units |
| Space Efficiency | Saves indoor space | Requires indoor unit placement |
| Maintenance | Easier access to all components | Can be more time consuming due to access and travel time |
Which System Is Right for Your Building?
The choice between a packaged unit and a split system depends on several factors:
- Building Size and Layout: Packaged units are ideal for smaller spaces or buildings with limited indoor space, while split systems can work well for spaces requiring low cost zoning.
- Climate: If your building is in an area prone to extreme weather, the outdoor placement of packaged units may lead to faster wear and tear of ALL components.
Conclusion
Both packaged units and split systems offer unique advantages depending on your building’s requirements. And it is not a one-size-fits-all solution. The choice will depend on your unique requirements. By understanding the key differences, you can choose the system that best fits your space, budget, and long-term goals.
