5 Ton Gree Flexx Ultra 18.5 SEER2 R32 Inverter Heat Pump System FXU60HP230V1R32AO, FXE60HP230V1R32AH
Sixty thousand BTU of inverter-driven heating and cooling, built from the FXU60HP230V1R32AO Flexx Ultra condenser and the FXE60HP230V1R32AH Flexx Eco air handler. Certified at 18.5 SEER2 under AHRI 217123259, this is the largest R32 Flexx pairing Gree builds, and it is also the unit contractors now specify for a 4 ton job. Gree narrowed the FXU/FXE system lineup to 3 ton and 5 ton, and the 60,000 BTU compressor throttles all the way down to 34,214 BTU/h, so a 48,000 BTU load lands comfortably inside its operating band instead of requiring a nominal 4 ton box that no longer exists in this series.
Is a 5 Ton Gree Flexx System the Right Size?
This system is built for the largest residential and light commercial ducted loads: big single family homes, multi-story additions, restaurants, retail suites, and churches where design cooling lands between roughly 34,000 and 60,000 BTU/h. Gree Flexx Ultra R32 submittal data puts the FXU60HP230V1R32AO at 34,214 to 61,600 BTU/h in cooling and 25,931 to 57,240 BTU/h in heating, with 53,000 BTU/h delivered at 95°F and 45,000 BTU/h still available at 17°F.
Because that band reaches down near 2.85 tons, a 4 ton calculated load is served without oversizing penalty. The compressor holds part load for most of the season and only climbs toward full output on design days. What deserves attention on a system this size is airflow: the FXE60 air handler is rated at 1,500 CFM against a maximum 1.0 in. w.c. external static pressure, so undersized returns, restrictive filter racks, or long flex runs will cost capacity before the equipment ever does. Duct sizing, latent load from occupancy and ventilation air, insulation levels, and glazing all belong in the calculation.
Ideal for: Large homes, two-story layouts with a single ducted system, restaurants and kitchens with high internal gain, retail and office suites, and any 4 ton replacement where the load has been verified, since the inverter modulates down to cover it.
Smaller load to cover? Drop to the 3 Ton Gree Flexx 18 SEER2 R32 Inverter Heat Pump System FXU36HP230V1R32AO, FXE36HP230V1R32AH, which handles both 2 ton and 3 ton applications. Browse the full Gree equipment lineup for multi-system and ductless options.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, duct design, ambient conditions, infiltration, internal gain, and a calculated heating and cooling load. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The FXU60 outdoor unit measures 35-7/16 in. wide by 49-5/8 in. high by 13-3/8 in. deep at 241.4 lb net, a narrow side-discharge cabinet that fits tight side yards where a conventional 5 ton condenser will not. Its gold fin coil carries a 1,500 hour salt spray rating. Indoors, the FXE60 cabinet is 24-13/16 in. wide by 52 in. high by 21-1/4 in. deep at 199.5 lb, with a blue fin coil, a five speed centrifugal blower moving 1,500 CFM, and 9.56 pt/hr of dehumidification. Line set is 3/8 in. liquid by 3/4 in. gas flared, precharged for 31 ft, with a rated range of 10 to 98 ft and up to 49 ft of elevation difference. Note that the 5 ton maximum line length is shorter than the 3 ton unit's, so verify the run before committing to a condenser location.

Frequently Asked Questions
My load calls for 4 tons. Is this 5 ton system the right choice?
It is. Gree builds the FXU/FXE pairing in 3 ton and 5 ton only, and this unit's cooling output modulates from 34,214 to 61,600 BTU/h. A 48,000 BTU/h load sits in the middle of that band, so the compressor holds steady at that output rather than cycling. On a 4 ton job this is the system to quote.
Will a 5 ton inverter short cycle on a smaller load?
Modulation is what prevents it. Where a fixed-capacity 5 ton compressor either runs at 60,000 BTU/h or shuts off, this one throttles down to roughly 34,000 BTU/h and holds. Long, low-output run cycles move more air across a cold coil, which is where latent removal happens. The published 9.56 pt/hr dehumidification rating reflects that behavior.
What is the maximum refrigerant line length on the FXU60?
Gree rates the FXU60HP230V1R32AO for total line lengths of 10 to 98 ft with a maximum 49 ft elevation difference, using 3/8 in. liquid and 3/4 in. gas flared connections. It ships precharged for 31 ft; add 0.215 oz of R32 per foot beyond that. This is shorter than the 3 ton unit's 164 ft rating, so plan the condenser location accordingly.
How much electric backup heat can the FXE60 air handler accept?
Gree lists heat kit options of 5, 6, 9, 10, 12, 15, and 20 kW for the 60,000 BTU air handler, the only FXE cabinet that goes to 20 kW. Circuit ampacity climbs with kit size, so size the feeder and breaker from the submittal table for the kit you select.
Will this condenser fit a narrow side yard?
The FXU60 cabinet is 13-3/8 in. deep and 35-7/16 in. wide with side discharge, which is why Gree markets it as a zero lot line design. It occupies noticeably less ground area than a conventional top-discharge 5 ton condenser. Always confirm the service and airflow clearances in the FXU condenser installation document before setting the pad.
Is R32 a drop-in for an existing R410A system?
No. R32 is a distinct A2L refrigerant with its own charge, oil, and service requirements, and this system is designed and charged for it from the factory. Both pieces are replaced together, and line sets from an R410A system should be evaluated and cleaned or replaced rather than reused without inspection.
