Commercial Packaged HVAC Units
Shop single package HVAC units for commercial replacement and new equipment projects. These systems house the heating, cooling, and air-handling components in one outdoor cabinet and are commonly used on commercial rooftops. Public HVAC Solutions carries Trane units in a range of capacities, electrical configurations, heating options, and refrigerants. Contractors, facility managers, property owners, and other buyers can compare available equipment and review each product listing for current specifications.
Single Package HVAC Equipment for Commercial Applications
Single package units are a common type of commercial HVAC equipment because the main heating, cooling, and air-handling components are contained in one cabinet. Most are installed on a rooftop and connected to the building's duct system, although installation can vary by model and application.
Choosing the right unit starts with the building and the equipment already in place. Capacity matters, but so do heating type, electrical service, airflow configuration, cabinet dimensions, controls, and ventilation needs. Available models can also differ by refrigerant and efficiency rating.
For replacement projects, it is especially important to compare the new equipment to the existing unit rather than relying on tonnage alone.
Packaged Rooftop HVAC Units
Many single package systems are commercial rooftop units, often called RTUs. Unlike split systems that use separate indoor and outdoor equipment, an RTU keeps the primary heating, cooling, and air-handling components together in one cabinet.
These systems are commonly found on retail buildings, offices, warehouses, multifamily properties, and other commercial facilities. Rooftop placement can also keep mechanical equipment out of valuable interior space.
Public HVAC Solutions carries Trane packaged rooftop equipment in different sizes and configurations. Inventory changes regularly, so product listings are the best place to confirm current tonnage, voltage, phase, heating type, refrigerant, and other model-specific information.
Replacing an Existing Single Package Unit
Replacing a single package unit usually starts with the equipment already on the building. Even when a new unit has the same nominal capacity as the old one, differences in cabinet design and connections can affect how easily it fits the existing installation.
For a rooftop replacement, pay particular attention to:
- Roof curb and footprint: Compare the new unit's dimensions and curb requirements with the existing rooftop opening.
- Supply and return locations: Make sure the duct connections line up with the building's current configuration.
- Airflow orientation: Confirm whether the installation requires downflow or horizontal airflow.
- Heating setup: Match the replacement to the building's gas or electric heating requirements.
- Electrical connections: Check the voltage, phase, disconnect location, and other model-specific electrical requirements.
- Controls and economizer setup: Existing thermostats, economizers, sensors, or building controls may not automatically work with a different unit.
- Refrigerant generation: Newer equipment may use a different refrigerant than the system being removed, which can affect installation and service requirements.
A replacement does not always need to be identical to the existing unit, but any differences need to be accounted for before the equipment reaches the jobsite. Confirm the replacement model, curb requirements, duct connections, controls, and any needed parts and supplies with a qualified HVAC professional before ordering.
Choosing the Right Single Package System
Single package equipment is often the most straightforward choice when a building is already designed around a rooftop HVAC system. Replacement projects, however, still require careful comparison between the existing unit and the new equipment.
Cabinet size, duct openings, curb dimensions, electrical connections, controls, and accessories can change from one model generation to another. A newer unit may also use a different refrigerant than the system being replaced.
That does not automatically rule out a replacement, but it can affect what is required during installation. Review the available equipment and product specifications, or contact Public HVAC Solutions if you need help narrowing down the options for a specific project.
Single Package Units Shipped Across the U.S. and Canada
Public HVAC Solutions ships HVAC equipment throughout the United States and Canada. Larger single package units typically ship by freight, with shipping details based on the equipment and destination.
Because inventory changes, check each product listing for current availability and specifications. Freight deliveries should be inspected when they arrive, and any visible damage or shortages should be noted on the delivery receipt before signing.
It is also a good idea to receive and inspect the equipment before scheduling installation, since transit times are not guaranteed.
Single Package HVAC FAQs
Can I replace an older single package unit with one of the same tonnage?
Not always. Tonnage tells you the cooling capacity, but it does not confirm that the replacement will match the existing installation. Cabinet dimensions, voltage, phase, heating capacity, duct openings, controls, refrigerant, and roof curb requirements can all be different.
For replacement projects, compare the full specifications of both units. A curb adapter, duct changes, electrical work, or control updates may be needed even when the tonnage is the same.
Can an R-454B single package unit replace an older R-410A unit?
Yes, a newer R-454B unit may be used as the replacement equipment for an older R-410A system, but R-454B is not a drop-in refrigerant for existing R-410A equipment.
The new unit must be designed for R-454B, and installation requirements can differ from older equipment. Always follow the manufacturer's specifications and have the replacement reviewed as a complete equipment change rather than simply a refrigerant change.
Are single package units only used in commercial buildings?
No. Packaged HVAC systems are used in both residential and commercial applications. The term simply means the main heating, cooling, and air-handling components are housed in one cabinet.
The equipment in this category is primarily geared toward commercial rooftop applications, where units often have different capacities, electrical requirements, controls, and accessories than residential packaged systems.
