Commercial Packaged Units

Commercial buildings demand HVAC capacity that residential equipment simply cannot match. A 5,000 square foot retail floor handling daily customer traffic, a restaurant kitchen pulling 6 ton of cooling against ovens and fryers, an office tenant suite needing precise zoning across 15 employees: these are the loads commercial HVAC package units are engineered to handle. By integrating compressor, evaporator, condenser, blower, and (depending on configuration) gas heat into a single rooftop cabinet, commercial package units cut installation cost, free up interior square footage, and centralize service access on the roof where technicians can work without disrupting tenants below.

Our commercial package unit selection spans 3 ton through 25 ton from Daikin and ACiQ. Daikin commercial inventory covers the DSC series (standard efficiency AC, 3 to 20 ton, R32), DHC series (high-efficiency AC, 3 to 5 ton with SEER2 ratings up to 16.6), DSG series (gas/electric, 5 to 25 ton with 81 percent AFUE) and DHG series (high-efficiency gas/electric, 3 to 5 ton, 16.2 to 16.6 SEER2), DSH series (light commercial heat pumps), DHH series (high-efficiency heat pumps), and the DH6TE split heat pump line with two-stage tandem compressors.

Older Daikin DBC, DBG, and DFG platforms remain compatible with current Daikin roof curbs and accessories. ACiQ commercial offerings include the RGV series gas commercial packaged units (3 to 10 ton, 90,000 to 180,000 BTU, R410A and R454B refrigerant variants), plus heat pump alternatives. Voltages run 208/230V single-phase (smaller 3 to 5 ton sizes), 208/230V three-phase, and 460V three-phase across the lineup, matched to typical commercial electrical service.

Best Commercial Package Units for...

Office Tenant Fit-Outs (3 to 5 Ton)

The best commercial package unit for office tenant fit-outs is a Daikin DSC series 5 ton 13.7 SEER2 230V single-phase model or a DSH series 3 ton 13.4 SEER2 light commercial heat pump, both of which fit standard tenant load profiles with straightforward electrical requirements.

Retail and Restaurant Buildings (6 to 10 Ton)

The best commercial package unit for retail and restaurant buildings is a Daikin DSC series 10 ton 15.2 IEER 230V three-phase configuration or a DH6TE series 10 ton 16 IEER commercial heat pump split. These mid-range options handle typical retail and restaurant cooling loads against high occupant turnover.

Gas Heating with Electric AC

The best commercial package unit for gas heating with electric AC is a Daikin DHG series 5 ton 16.2 SEER2 commercial gas package (140K BTU, 230V three-phase) or an ACiQ RGV series 5 ton 13.4 SEER2 gas commercial unit (150K BTU). Both deliver the gas/electric combination most retail and small office buildings prefer.

Large Commercial Loads (15 to 25 Ton)

The best commercial package unit for large commercial loads is a Daikin DSC series 20 ton 14.2 IEER 230V three-phase model or a DFG series 25 ton 400K BTU gas/electric model in 460V three-phase. These sizes cover larger retail spaces, banquet facilities, and light industrial operations needing single-cabinet capacity at scale.
