Goodman Central Air Conditioners are among the best central air conditioner brands because of their overall excellent SEER ratings and their compatibility with True HEPA Filters. They also stand apart because of their great warranty coverage, a trademark of the Goodman brand. Unfortunately, they also tend to be a bit noisy, which the GSX16 does little to mitigate.\r\n\r\nWhy We Like It - Goodman 3 Ton AC Unit\r\nThe Goodman 3 Ton AC Unit, specifically the GSX16, is a mid-range air conditioner available to those on a budget, who are looking for their first air conditioner, or who are looking to spend less money up front. The 16 SEER Rating also falls between the 14-16 guideline recommended for homeowners which is always nice.\r\n\r\nPerformance\r\nGoodman Air Conditioning Units traditionally have a good SEER rating, and this one is no exception and falls between the recommended 14-16 for homes like the Amana Air Conditioner. The single-stage compressor means the unit is less energy efficient though because the unit will always run at max power. The dB levels are high for central air conditioners so be prepared for some noise too. The PSC Condenser Fan won\u2019t help with this noise level either.\r\nEnergy Efficiency\r\nThis Goodman Unit, as we\u2019ve already seen, will always run at maximum power because of the single-stage compressor. So if you\u2019re looking to save on energy costs in the long run this unit is probably not the best bet. Try the Carrier Central Air Conditioner if saving in the long term is your goal. However, the cooling capacity this central air conditioner will provide is going to be high quality all-year round.\r\nFiltration\r\nUnlike a lot of other air conditioning units, the GSX16, like its cousin the Goodman Air Conditioner, is actually compatible with True HEPA Filters and thus provides a greater amount of comfort because of the cleaner air. They also feature an electronic air cleaner and a UV light for particle destroying as well as particle trapping.\r\nDurability\r\nThe Goodman Brand offers compressors that are manufactured by Copeland. Copeland is, by far, the leading manufacturer when it comes to compressors in a heat pump or AC unit. The liquid line is a solid \u215c inches and the suction line is also solid at \u00be inches. And let\u2019s not forget about the innovative coil that\u2019s made of aluminum to prevent corrosion and leaks between metal.\r\nValue\r\nGoodman maintains their stellar tradition of backing up all their products with stellar warranties. These include a 2-Year Unit Replacement Limited Warranty and a 10-Year Parts Limited Warranty. Unfortunately, Goodman doesn\u2019t have factory-designated installers because installation is probably the one area you don\u2019t want to skimp on when it comes to Central AC. You\u2019ll have to rely on HVAC installers instead.\r\nGoodman 3 Ton AC Unit Wrap Up\r\nThe drawbacks of the Goodman Central Air Conditioner is the lack of Factory-Designated Installers and that it\u2019s less energy-efficient than most other models because of the single-stage compressor. If you\u2019re looking to save money up-front this is a fine machine. But if you\u2019re looking for long-term savings, you\u2019d do well to check out other Goodman models.
