The Carrier WeatherMaker 9300 TS (also known as the 9300TS-58MTA) is a gas furnace with an efficiency rating of 93 percent AFUE. According to the manufacturer, its high efficiency is due to the use of two heat exchangers that receive air from a two-speed inducer. The primary exchanger, the Super-S, recycles 80 percent of the heat produced by the furnaces operation, and the secondary heat exchanger recycles 13 percent of remaining heat. With both low- and high-stage heating, the WeatherMaker’s Comfort Heat Technology is intended to enable the furnace to quickly reach and efficiently maintain desired indoor temperatures.
For product reliability, the heat exchangers are manufactured with aluminized steel making them corrosion-resistant. The unit has a sealed combustion system to minimize cold drafts that may cause the unit work more than necessary. Carrier also notes that the unit’s hot surface ignition was designed to conserves gas.
Several accessories are available with the 9300TS-58MTA that improve air quality. For example, a system humidifier can be installed or an air cleaner cabinet allowing use of Carrier’s high efficiency air filter.
