3 Best 4 Ton Air Conditioning Units 2025 in the United States

The Goodman 4 Ton 14 SEER Package Air Conditioner System is a solid choice for cooling large spaces with a cooling capacity of 48,000 BTU. One of its significant strengths is the 10-year parts limited warranty, which offers peace of mind if installed by a qualified professional and registered online. This unit uses R-410A refrigerant, which is more environmentally friendly compared to older refrigerants.

The 14 SEER rating indicates decent energy efficiency, though it is not the highest available on the market, which means there might be more cost-effective options in terms of energy savings in the long run. Accessories like heat kits, thermostats, and duct adapters are sold separately, potentially increasing the overall cost. Also, installation and maintenance need to be handled by professionals, which adds to the initial investment.

Its large size and weight (377 pounds) might make it more challenging to install in some areas. This Goodman model fits well for those needing a robust cooling solution with a good warranty but might not be ideal for users looking for the highest energy efficiency.

The Goodman 4 TON 14 SEER2 Multi-Position R-32 AC Only System offers a cooling capacity of 48,000 BTUs, making it suitable for larger spaces. The SEER rating of 14 indicates moderate energy efficiency, which can help reduce energy costs but isn't the best in class. The unit uses R-410A refrigerant, known for its efficiency and environmental benefits compared to older refrigerants.

The split system design with separate condenser and air handler units provides flexible installation options. The insulated feature suggests it may operate relatively quietly. Installation and maintenance might require professional assistance, which can add to the cost.

This unit can be a viable option for those needing reliable cooling for a large area, with a moderate emphasis on energy efficiency. The product is discontinued by the manufacturer, which could affect the availability of parts and warranty service in the future.

The Copeland 4 Ton Scroll HP A/C Condenser Compressor, model ZR48K5-PFV-800, offers a substantial cooling capacity of 48,200 BTU, making it suitable for larger spaces or homes. One of its key strengths is the use of a scroll compressor, which is known for its reliability and efficiency. It operates silently, which can be a significant advantage for residential use where noise levels can be a concern.

However, it's important to note that this unit is designed for R22 refrigerant, which is being phased out due to environmental concerns. This might limit its long-term usability unless retrofitting for a different refrigerant is possible and feasible. The compressor also requires specific line sizes for discharge and suction, and potential additional mounting, piping, and field modifications might be necessary, which could increase installation complexity and cost.

This compressor is powerful and quiet but may pose challenges with installation and long-term refrigerant compatibility.
