The Goodman 3 TON 14.3 SEER2 R-32 AC Condenser is a solid choice for cooling homes around 1700 square feet. It offers a decent cooling capacity of 36,000 BTUs (3 tons), which is suitable for medium-sized spaces. The SEER rating of 14.3 means it meets current energy efficiency standards, helping to keep electricity costs reasonable, though there are more efficient models if saving energy is a top priority.

This unit uses R-32 refrigerant, which is more environmentally friendly but requires compatible air handlers or coils, so if you have older equipment using a different refrigerant, you may need additional upgrades. Its rotary scroll compressor is reliable but it does not have inverter technology, so it may run at full power or off rather than adjusting smoothly to cooling needs, which can affect energy use and noise. Goodman units are generally designed to operate quietly outdoors.

It comes with a 10-year parts limited warranty if installed by a professional and registered within 60 days, offering peace of mind for long-term use. This product is the outside condenser only and works with separate indoor components, so installation involves pairing with compatible parts and possibly extra accessories sold separately. This Goodman model is a dependable and straightforward option for those looking to replace or upgrade a central AC condenser without requiring top-tier energy efficiency or the latest inverter features.

Cooling Capacity (BTUs)
Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER)

Most important from
103 reviews

Cooling Capacity (BTUs)
Delivers powerful cooling that quickly lowers indoor temperatures, making it highly effective for medium to large homes.
Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER)
Offers excellent value with a great price point and energy-efficient performance.

The Goodman 3 TON 13.4 SEER2 Horizontal AC Packaged Unit offers a solid cooling capacity of 36,000 BTUs, making it suitable for medium to large homes needing effective temperature control. Its SEER rating of 13.4 reflects moderate energy efficiency, which is acceptable but not top-tier compared to newer models that offer higher efficiency and potentially lower electricity bills. Being a packaged unit means it combines all components in one casing, which can simplify installation in space-limited areas. The unit uses R-32 refrigerant, which is more environmentally friendly than older refrigerants. However, this model has been discontinued, so finding replacement parts or service might be more challenging over time.

This Goodman model can be a dependable choice if you find it at a good price and need a straightforward, no-frills central AC solution, though newer models may offer better efficiency and support.

Buying Guide for the Best Central Air Conditioners

Choosing the right central air conditioner for your home is crucial for maintaining comfort and energy efficiency. The right unit will keep your home cool during the hot months without causing your energy bills to skyrocket. To make an informed decision, you need to understand the key specifications and how they relate to your specific needs. Here are the most important specs to consider when selecting a central air conditioner.
Cooling Capacity (BTUs)Cooling capacity, measured in British Thermal Units (BTUs), indicates how much heat an air conditioner can remove from your home in an hour. This spec is important because it determines how effectively the unit can cool your space. Units with too low BTUs will struggle to cool your home, while those with too high BTUs will cycle on and off too frequently, wasting energy. To navigate this, consider the size of the area you need to cool. For small homes or apartments, 12,000-24,000 BTUs might be sufficient. Medium-sized homes may require 24,000-36,000 BTUs, and larger homes might need 36,000-60,000 BTUs. Match the BTU rating to your home's square footage and layout for optimal performance.
Energy Efficiency Ratio (EER) and Seasonal Energy Efficiency Ratio (SEER)EER and SEER ratings measure the energy efficiency of an air conditioner. EER is calculated by dividing the cooling capacity by the power input, while SEER is the ratio of cooling output over a typical cooling season divided by the total electric energy input. Higher ratings mean better efficiency, which is important for reducing energy consumption and lowering utility bills. EER values typically range from 8 to 12, and SEER values range from 13 to 25. For moderate climates, a SEER rating of 14-16 is usually sufficient. In hotter climates, a SEER rating of 18 or higher is recommended. Choose a unit with higher EER and SEER ratings if energy efficiency and long-term savings are priorities for you.
Noise LevelThe noise level of a central air conditioner, measured in decibels (dB), indicates how loud the unit will be during operation. This is important for maintaining a peaceful home environment. Noise levels can range from 50 dB (quiet) to 80 dB (loud). For a quieter experience, look for units with noise levels below 60 dB. If the air conditioner will be installed near bedrooms or living areas, prioritize lower noise levels to avoid disturbances.
Compressor TypeThe compressor is the heart of the air conditioner, and its type affects performance and efficiency. There are three main types: single-stage, two-stage, and variable-speed. Single-stage compressors operate at full capacity or not at all, which can lead to temperature fluctuations and higher energy use. Two-stage compressors can run at two different speeds, providing better temperature control and efficiency. Variable-speed compressors adjust their speed to match cooling needs, offering the best efficiency and comfort. If you value consistent temperature and energy savings, consider a two-stage or variable-speed compressor.
WarrantyThe warranty of a central air conditioner covers repairs and replacements for a specified period. This is important for protecting your investment and ensuring long-term reliability. Warranties can range from 5 to 15 years, with some manufacturers offering extended coverage for critical components like the compressor. When comparing warranties, consider the length and what is covered. A longer, comprehensive warranty can provide peace of mind and save you money on potential repairs.
