4 Ton Goodman R-32 Two-Stage Heat Pump System – GLZT7CA4810 & AMVT60DP1300
Larger homes and two-story floor plans need more airflow and more heating reserve, and this 4 ton Goodman system is built for that. The GLZT7CA4810 two-stage R-32 heat pump delivers a nominal 48,000 BTU/h. It is paired with the AMVT60DP1300, a 24.5-inch D-cabinet air handler with a 1 HP variable-speed blower that moves up to 1,600 CFM on high stage. With electric heat strip options up to 25 kW and communicating ComfortBridge controls, it suits growing families, larger ranch homes and contractors replacing aging 4 ton equipment.
Is a 4 Ton Heat Pump System the Right Size?
A 4 ton system handles roughly 48,000 BTU/h of heating and cooling load. Homes that land here often have more glass, higher ceilings, a second floor or a hot attic adding to the cooling load. Sizing up to 4 tons should be based on a measured load, not just a larger floor plan. Start with the AC tonnage calculator and confirm with a Manual J before ordering.
Duct capacity matters more at this size. On high stage the AMVT60DP1300 targets 1,600 CFM with a 4 ton outdoor unit, so undersized returns or long supply runs can limit performance. Also plan for winter: colder regions often need a larger heat strip, which affects the air handler's breaker and wire size.
Ideal for: Larger single-family homes, two-story houses, homes with high ceilings or large window areas, and replacement of existing 4 ton heat pump systems.

Recommended applications are general guidelines only. Actual system requirements depend on insulation, climate, duct design, window load, occupancy and desired indoor temperature. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

The GLZT7CA4810 moves to a larger 7mm copper tube / enhanced aluminum fin coil and 1-1/8" suction valve. It holds a 229 oz factory R-32 charge, the largest in the GLZT7C series, sized for 15 feet of 3/8" liquid line. Goodman notes that installers supply 7/8" to 1-1/8" adapters for the suction connections. The AMVT60DP1300 runs 1,072 CFM on low stage and 1,600 CFM on high with this outdoor unit, and its 24.5" D cabinet accepts Goodman's largest heater kits. Both components are also listed separately: the GLZT7CA4810 heat pump and the AMVT60DP1300 air handler.

Frequently Asked Questions
Is a 4 ton heat pump system a good fit for a two-story home?
Often, yes. Two-story and larger homes frequently land in the 48,000 BTU/h range. Still, confirm the load with a Manual J, since insulation and window exposure can shift the right size up or down.
Why does the 4 ton condenser come with a 5 ton air handler?
Goodman rates the AMVT60DP1300 for both 4 and 5 ton outdoor units. With the GLZT7CA4810, it runs 1,072 CFM on low stage and 1,600 CFM on high stage.
Do I need suction line adapters for the GLZT7CA4810?
Goodman's spec sheet notes that installers supply 7/8" to 1-1/8" adapters for suction connections. The condenser uses a 1-1/8" suction valve, and 25' and 50' 1-1/8" & 3/8" copper line sets are offered as options.
How much R-32 refrigerant is in the 4 ton heat pump?
The GLZT7CA4810 ships with 229 oz of R-32, charged for 15 feet of 3/8" liquid line. Adjust the final charge using the installation instructions' Final Charge Procedure.
How does a two-stage compressor benefit a larger home?
The two-stage Copeland UltraTech scroll runs at reduced capacity during milder conditions and moves to full capacity on peak days. Together with the variable-speed AMVT60DP1300, this gives steadier temperatures and better humidity control.
Can I use a conventional thermostat instead of a communicating one?
Yes. The GLZT7C series supports communicating ComfortBridge wiring and also has a color-coded terminal strip for non-communicating setup, so compatible 3H/2C heat pump thermostats can be used.
