Goodman
4 Ton Air Conditioner
Goodman Single-Stage, R-32 | GLXS3BN4810
$2,468.00
A 4 ton air conditioner delivers 48,000 BTU and is built for larger homes — typically two-story or open-plan houses around 2,100 to 2,400 square feet. At this capacity, the ductwork and electrical feeding the system matter as much as the unit itself.

A large air conditioner can only deliver its rated cooling if the rest of the system can keep up. Undersized ducts choke airflow, leaving far rooms warm no matter how big the outdoor unit is, so it's worth confirming the duct runs and blower are rated for the CFM a 4 ton needs. The electrical side matters too — check that the breaker and wiring are sized for the unit's requirements before install.
For a home this size, how the unit modulates also shapes comfort:
Planning a 4 ton install for a larger home? Let's check airflow and specs →
A 4 ton unit (48,000 BTU) typically fits larger homes of about 2,100–2,400 sq ft, especially two-story or open-plan layouts — subject to a load calculation.
48,000 BTU per hour — 4 × 12,000 BTU/h.
Not always. Larger systems need ducts and returns sized for higher airflow; undersized ducts restrict a 4 ton unit and leave rooms uneven. Have the duct capacity checked before installing.
In a large home, often yes. Staged and variable-speed compressors run longer at lower output, which evens out temperatures between floors and pulls more humidity than a single-stage unit.
They vary by model, but a 4 ton unit draws more than smaller sizes, so the circuit breaker and wiring must be sized to the unit's rated load. Confirm the electrical panel can support it before install.
