Commercial AC Split System Bundles

Matched Commercial AC Split Systems: How the Pairs Are Built and Rated, and What Ships

Every listing on this page is a Rheem condensing unit and a Rheem air handler sold together as one system. The value of a bundle is not just convenience. A split system’s capacity and efficiency are certified for a specific outdoor and indoor combination, so buying a pair that is already matched removes the most common replacement mistake: a new condenser on an indoor section it was never rated with. This page explains how the pairs here are put together, how to read their ratings, what arrives on the truck, and what you still need to supply.

Each bundle’s part number is the condenser model and the air handler model joined together, for example RACY2120CAZ-RHCYA2120CAS. That makes it easy to confirm exactly which two pieces you are getting and to look them up individually on Commercial AC Condensing Units and Commercial Air Handlers.

Why the 6.5 Ton System Uses a 7.5 Ton Air Handler

The 6.5 ton RACY2078 condenser is paired with the RHCYA2090 air handler, the same cabinet used on the 7.5 ton system. That is the indoor section listed for this condenser, not a substitution. The belt-drive blower and VFD give a wide airflow range, so the same cabinet can be set to the airflow a 6.5 ton condenser needs. When you commission it, set airflow for 6.5 tons using the installation manual rather than leaving it where a 7.5 ton system would run, or you will lose dehumidification and the system will not match its published rating.

Two Circuits on the 3 to 5 Ton Systems

The 3 to 5 ton bundles pair a three-phase condenser with a single-phase 208/230V RH2TY air handler. That is common in light commercial work, where the condenser is fed from a three-phase panel and the air handler from a single-phase circuit. Make sure the building has both available at the right locations. If the air handler location only has 480V three-phase, a 460V RH2TY is listed separately on Commercial Air Handlers, and you would need to confirm that pairing is approved before buying components instead of the bundle.

How Matched Ratings Work

Capacity and efficiency for split systems are certified by combination. The outdoor unit, indoor coil, and in many cases the blower and its settings are all part of the tested system. The AHRI Directory lists certified combinations with a reference number, rated capacity, and efficiency. For the 3 to 5 ton systems, the efficiency metric is SEER2 with EER2; for 6.5 tons and up, it is EER and IEER. When a specification, rebate application, or energy code compliance form asks for system efficiency, it is asking for the matched combination’s rating, not the condenser’s alone. Pull the AHRI certificate for the exact bundle and keep it with the job file.

Ratings assume the system is installed and set up as the manufacturer specifies: correct line-set size and length, proper refrigerant charge, and airflow set to the design value. A matched system with airflow left at the wrong setting will not perform to its rating.

What Ships and What You Supply

A bundle ships the two pieces of equipment named in the listing: the condensing unit and the air handler. Unless the listing specifically says otherwise, plan to supply:

  • Refrigerant line set, insulation, and any fittings or oil traps required for the run
  • Thermostat or controller, two-stage capable on the larger systems
  • Electrical disconnects, whips, breakers, and wiring for each section
  • Condenser pad, roof rails, or dunnage, and air handler pad, stand, or isolators
  • Condensate trap, drain piping, secondary pan, float switch, or pump as the location requires
  • Filters, electric heat accessories, and any economizer or outdoor-air components the design calls for
  • Refrigerant for any additional charge needed beyond the factory charge for longer line sets

The two pieces may ship separately and arrive on different days, especially on the larger systems that move by freight. Check both against the bill of lading and note any damage before signing.

Paperwork Worth Keeping

Save the installation manuals for both sections, the AHRI certificate for the combination, the nameplate photos with serial numbers, and a startup sheet showing line-set length, added charge, measured superheat or subcooling, external static pressure, and the airflow and VFD settings. When the owner registers the equipment, files a utility rebate, or calls for service two summers from now, that one folder answers most of the questions anyone will ask.

When a Bundle Is the Right Choice

  • Both the condenser and air handler are being replaced.
  • The existing system uses R-410A or R-22 and the new one is R-454B, so the indoor coil must change anyway.
  • The job needs a documented AHRI combination for code compliance, an engineer’s submittal, or a utility program.
  • You want one order, one set of documents, and one equipment schedule entry.

If the existing air handler is staying and is already approved with the new condenser, buying the condenser alone on Commercial AC Condensing Units can make more sense.

Sizing a Bundle for the Job

Bundles make selection easy, which is also how oversizing happens. A matched system that is too large for the space short-cycles, removes less moisture, and leaves the space feeling clammy even when the thermostat is satisfied. That matters most in humid climates and in spaces with high ventilation loads, like restaurants and gyms. Before picking a bundle by the tonnage of the old system, confirm the load. The larger RACY systems help here because they are listed as two-stage, so they can run at reduced capacity during mild weather, but staging only helps if the controller is wired to use it.

Also think about how the load is split across the building. One 20 ton system serving a large open floor is simpler to maintain, while two 10 ton systems give you redundancy if one goes down and can serve zones with different schedules. For a business that cannot afford to lose cooling, such as a medical office or a restaurant in summer, two smaller systems are often worth the extra installation cost.

Refrigerant Notes

All systems on this page use R-454B, an A2L refrigerant. Installers need A2L-rated recovery, evacuation, and leak detection tools, and the system must be installed following Rheem’s instructions and the applicable safety standards, including any refrigerant detection and mitigation requirements at the air handler. For a heat pump version of these systems, see Commercial Heat Pump Split System Bundles.

Frequently Asked Questions

What is included in a commercial AC split system bundle?

The condensing unit and air handler named in the listing. Line set, controls, electrical, mounting, and drain materials are supplied separately unless the listing says otherwise.

How do I find the AHRI reference number for a bundle?

Search the AHRI Directory using the condenser and air handler model numbers that make up the bundle part number.

Why does the 3 ton bundle need a single-phase circuit?

The 3 to 5 ton bundles use a 208/230V single-phase RH2TY air handler with a three-phase condenser. Each section needs its own circuit at its own voltage.

Can I order a 460V condenser with a 208/230V air handler on the larger systems?

The 6.5 to 20 ton bundles here are listed with matching voltages on both sections. If you need mixed voltages, buy the components separately and confirm the pairing.

Does a matched bundle need any field setup?

Yes. Airflow, charge, and staging still need to be set at startup, following the installation manual, for the system to meet its rating.

Can I add heat to these systems?

These are cooling systems. Check the air handler installation manual for approved electric heat accessories, or look at Commercial Heat Pump Split System Bundles.
