ALXS3NN4810A
Amana 48,000 BTU 4 Ton
Single-Stage
AC Air Conditioner
The ALXS3NN family is a central AC outdoor condenser option designed for straightforward, reliable cooling. Comfort still depends on correct sizing, the right indoor coil match, and a clean, properly commissioned install.
A 4 ton system is typically reserved for larger homes, higher heat gain designs, or situations where multiple zones/levels are being conditioned through a single duct system with adequate airflow. It’s also common when the existing equipment was truly large and the load still supports it.
The pitfall is assuming the old tonnage was correct. If upgrades were done over time (windows, air sealing, insulation), the real load can drop. Oversizing at 4 tons can mean short cycling, humidity issues, and loud airflow. We confirm actual load drivers, duct capability, and coil match before moving forward.
We confirm sizing and pricing on site – no pressure, no upsells.

Technical documents
Key features of the ALXS3N family
What it is:
- Outdoor central AC condenser (split system) using R-32 refrigerant
- Single-stage operation (simple, straightforward cooling)
Build & serviceability (equipment details):
- Copper tube / enhanced aluminum coil (manufacturer design)
- Steel louver coil guard to help protect the outdoor coil
- Removable grille-style top; compact footprint
- Top + side service access (easier maintenance access)
- Sweat connection service valves with gauge ports
- Enclosed contactor + high-pressure switch (manufacturer safety/control components)
What actually determines comfort (install + matching):
- Must be paired with the right indoor coil / matched system for proper performance
- Airflow has to be set up correctly (duct limitations matter as much as the condenser)
- Proper commissioning: evacuation, leak check, then charge verification using the correct method
Ownership basics:
- Filter changes and keeping coils clean protect capacity and efficiency
- Warranty note: Amana 10-year parts limited warranty typically requires online registration within 60 days of installation (Peak Comfort HVAC handles this for you)
