Goodman Air Conditioners are among the best central air conditioner brands because of their overall excellent SEER ratings and their compatibility with True HEPA Filters. The Copeland compressors are a very nice touch as well. Of course, it does retain some negatives too. Goodman ACs do tend to be noisier than most of their competitors.\r\n\r\nWhy We Like It - Goodman Central Air Conditioner\r\nThe Goodman Central Air Conditioner, specifically the GSX14, is an excellent 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. And with the 15 SEER rating it falls between the recommended 14-16 range for homeowners.\r\n\r\nPerformance\r\nThe Goodman Air Conditioning Units offer a 15 SEER rating which is between the 14-16 rating rating recommended for houses, just 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 72 dB is high for central air conditioners so be prepared for some noise too.\r\nEnergy Efficiency\r\nThis Goodman AC 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.\r\nFiltration\r\nUnlike a lot of other air conditioning units, the GSX 14, 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\nThere\u2019s plenty to love about the construction of the Goodman Air Conditioners. The indoor coil is made of aluminum and thus reduces the chance of corrosion and leaks because there are no dissimilar metals. Goodman compressors are also made by Copeland. Copeland is, by far, the leading manufacturer when it comes to compressors in a heat pump or AC unit.\r\nValue\r\nGoodman offers their traditionally-excellent warranties which includes a 10-year parts limited warranty provided it is registered online within 60 days of installation, which shouldn\u2019t be too hard. Speaking of installation, it\u2019s unfortunate that 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.\r\nGoodman Central Air Conditioner 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 there\u2019s one thing you shouldn\u2019t skimp on with ACs it\u2019s getting them installed properly. A properly installed unit runs more efficiently, for longer, and with better results.
