4 Ton Goodman R-410A Variable Speed Air Handler — AMVT48DP1400
The Goodman AMVT48DP1400 is a 4-ton (48,000 BTU/h) multi-position variable-speed air handler for R-410A residential cooling and heat pump systems. Built in a wide 24.5-inch D-cabinet with a 1 HP ECM blower, ComfortBridge communicating controls, and a factory-installed thermal expansion valve, it moves the high airflow a 4-ton system demands while keeping operation quiet and efficient.
Is a 4 Ton Air Handler the Right Size?
A 4-ton air handler supports approximately 48,000 BTU/h of cooling, generally matching larger homes in the range of about 2,000 to 2,400 square feet. Sizing should follow a load calculation and the capacity of the matched outdoor unit rather than square footage alone.
At 4 tons, duct design is critical. The AMVT48DP1400's wide 24.5-inch cabinet and higher nominal airflow are built to move more air, which requires generously sized returns and supply trunks to avoid noise and static-pressure problems. Insulation, climate, window load, and the matched condenser or heat pump all influence whether 4 tons is appropriate.
Ideal for: larger 4-ton residential systems with full-size ductwork, installed upflow, downflow, or horizontal and matched to an R-410A condenser or heat pump.
Need a smaller unit? Step down to the 3.5-ton Goodman AMVT42CP1400 or the 2.5-ton AMVT30BP1400 variable-speed air handler.
Recommended sizing is a general guideline only. Actual requirements depend on insulation, climate, duct design, window load, and the matched outdoor unit. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Frequently Asked Questions
What is the difference between the AMVT48DP1400 and the AMVT48CP1400?
Both are 4-ton variable-speed air handlers, but the AMVT48DP1400 uses the wider 24.5-inch D-cabinet, while the AMVT48CP1400 uses a 21-inch C-cabinet. The D-cabinet provides a larger coil face and generous airflow for full 4-ton systems.
What is the maximum airflow of the AMVT48DP1400?
The variable-speed ECM blower delivers a nominal airflow range of approximately 1,072 to 1,600 CFM, allowing the unit to match the demand of a 4-ton system and adjust for comfort and humidity control.
Why choose a variable-speed ECM blower over a standard motor?
A variable-speed ECM blower ramps airflow up and down gradually, which improves energy efficiency, enhances dehumidification, and runs more quietly than a fixed-speed PSC motor—especially valuable on a larger 4-ton system.
Can I add electric backup heat to this 4-ton air handler?
Yes. Field-installed electric heat kits are available in 5 kW, 8 kW, 10 kW, and 15 kW sizes to provide supplemental or backup heat. Sizing the kit increases the unit's electrical circuit requirements.
Is the AMVT48DP1400 compatible with communicating thermostats?
Yes. With integrated ComfortBridge technology, it supports communicating operation and automatic system configuration, plus Bluetooth setup and diagnostics through the Goodman CoolCloud app.
What suction and liquid line sizes does the 4-ton unit use?
The AMVT48DP1400 has a 3/8" liquid line connection and a 7/8" suction line connection, with a 3/4" FPT condensate drain. Confirm these against your matched outdoor unit and line set.
