The Goodman GSX13 is one of many affordable central air conditioners focused on high efficiency and quiet operation, standing out via its low price tag and slew of useful features. It\u2019s Energy Star rated, it\u2019s built with a quiet condenser fan motor for quieter operation, and it\u2019s overall a solid unit that proves that good air conditioning doesn\u2019t have to cost a fortune. If you\u2019re looking for the best central air conditioner on a budget, the Goodman GSX13 is a solid contender, but it's middling efficiency and faulty compressor design prevent it from being an immediate recommendation.\r\nWhy We Like It - Goodman GSX13\r\nThe Goodman GSX13 is a high quality HVAC system that serves as proof that the Goodman brand is synonymous with quality even in the budget sector, providing a solid, reasonably energy efficient air conditioner at an appealing price. It\u2019s not quite as efficient as some of its competition, but it\u2019s a compelling product that should serve most households well.\r\n\r\nPerformance\r\nFor its price, the Goodman GSX13 is a solid performer. It\u2019s not at the same caliber as the higher end Goodman Air Conditioner, which brings a great number of internal upgrades to the table, but it gets the job done cheaply and effectively. Like the Carrier Central Air Conditioner, it\u2019s designed to operate quietly (relative to other ACs; any unit will be loud), and though it struggles a bit in extreme temps it\u2019s good enough at cooling most households.\r\nEnergy Efficiency\r\nEfficiency is decent but not great on the Goodman GSX13. When running optimally, it\u2019s solid enough for a budget unit, rated for up to 14 SEERs; this isn\u2019t the absolute best figure for a budget unit, but it\u2019s not a poor one either. If efficiency is a concern, you\u2019re best off either paying extra for a higher end unit or turning your head to the Amana Air Conditioner instead. Goodman\u2019s ComfortBridge technology is incorporated to improve efficiency, though its usage of single-phase power works against it.\r\nFiltration\r\nThe Goodman GSX13 comes with a factory installed filter drier, meaning it\u2019s adequately filtered. Filter driers work in two ways; the filter keeps particulate matter out, while the drier helps keep condensation and moisture out of the unit\u2019s tubing. This in turn prevents it from freezing over, helping improve durability.\r\nDurability\r\nDurability is a very mixed bag on the Goodman GSX13 due to poor quality control. Some units have faulty compressors that die after only a few years or even just a few months of operation, meaning your new unit is at risk of breaking at any time. Units without these faulty compressors are fine, but there\u2019s no way of knowing if you\u2019ve got one of the good ones or not until it dies.\r\nValue\r\nCompetitive pricing and decent efficiency make it abundantly clear that value is the main selling point of the Goodman GSX13. It handles heating, cooling, and filtration all at a low price. It\u2019s not as good a value proposition as the slightly more efficient (and more reliable) Amana Air Conditioner, but it strikes a solid blend of price, efficiency, and value nonetheless.\r\nGoodman GSX13 Wrap-up\r\nCompared to other Goodman air conditioners it may not be the flashiest, but the GSX13 is a mostly solid product. It\u2019s a bit hard to recommend over the Amana Air Conditioner, and its faulty compressor design doesn\u2019t help its case at all, but when the unit works it\u2019s good for all but the warmest climates and its low price is hard to ignore. If you\u2019re willing to roll the dice and can\u2019t spend extra on something better, it\u2019s worth picking up, but I suspect many buyers will be better off picking up something else if at all possible.
