5 Ton GrandAire 16 SEER2 R454B Side Discharge Inverter Heat Pump Condenser, W5H9V60AKAAA
The GrandAire W5H9V60AKAAA is the largest heat pump in the W5H9V family. It's a 5 ton R-454B inverter heat pump with a twin-rotary compressor that delivers up to 64,500 BTU/h of heating and holds 52,000 BTU/h at 5°F. Cooling modulates from 11,400 to 56,300 BTU/h, with ratings of 16 SEER2, 10 EER2, and 9.0 HSPF2. That's the widest turndown in the series, so one outdoor unit can run gently on mild days and still handle the heaviest loads in a large home. Like every W5H9V, it uses a side discharge design that keeps the airflow and noise directed away from the house. Pair it with the GrandAire WCVL605CD variable speed air handler, or compare all 5 ton heat pump condensers.
Is a 5 Ton Heat Pump the Right Size?
Five tons is the top of the residential range. It's typically reserved for large homes, open floor plans with vaulted ceilings, houses with extensive glass, or single systems serving big square footage in hot or cold climates. Thanks to its inverter compressor, the W5H9V60AKAAA avoids the short-cycling and humidity problems an oversized fixed-speed unit can cause.
Before choosing 5 tons, confirm the load with a Manual J calculation and make sure the ductwork can move the airflow. The matched WCVL605CD runs up to 1,807 CFM, so undersized return or supply ducts limit performance. Outdoor clearance, electrical service (MCA 40), and line set routing should also be checked.
Ideal for: Large single-family homes, open-concept and vaulted-ceiling layouts, and high-load replacement projects that need maximum capacity from one side discharge heat pump.
Need less capacity? Consider the 4 Ton GrandAire 16.5 SEER2 Inverter Heat Pump, W5H9V48AKAAA for slightly smaller loads with higher SEER2 efficiency.
Recommended applications are general guidelines only. Actual system requirements depend on insulation, climate, duct design, window area, and occupancy. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What's the difference between the 4 ton and 5 ton W5H9V heat pumps?
The 5 ton reaches up to 64,500 BTU/h of heating and 52,000 BTU/h at 5°F, compared with 57,300 and 46,000 BTU/h for the 4 ton. It uses a taller 52.48" cabinet and needs a 40 amp minimum circuit ampacity.
What thermostats or controllers work with the W5H9V60AKAAA system?
Grandaire lists four control options: the 120N(X6) wired controller, the 120N(X6W) wired controller with built-in Wi-Fi, a wireless remote, or a third-party 24V thermostat.
Does the W5H9V60AKAAA ship pre-charged with refrigerant?
Yes. It comes with 183.42 oz of R-454B, enough for up to 24.6 ft of line set. Longer runs need 0.7 oz of additional refrigerant per foot.
What do the crankcase heater and chassis heater do?
The crankcase heater keeps the compressor oil warm to protect the compressor during cold starts. The chassis heater helps keep the base pan from icing up during winter defrost cycles. Both come standard.
What should installers know about R-454B?
R-454B is a lower-GWP A2L refrigerant replacing R-410A in new equipment. Use recovery equipment, gauges, and leak detectors rated for R-454B, and follow the A2L requirements in the installation instructions.
How large and heavy is the 5 ton outdoor unit?
The W5H9V60AKAAA measures 37.48" W x 16.34" D x 52.48" H and weighs 242.95 lb net. Plan for a pad or bracket rated for that weight.
