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.
In July of 2003 I purchased and installed this furnace in my home with a friend. It is now December of 2015 and I’ve never had an issue. It’s been 100% reliable. I change filters about once a year and nothing else. I usually operate in low fire mode which gives a longer run time and very few cycles per day as my thermostat is set for a wide comfort temperature range. Often my furnace only kicks on once a day and raises my home temperature from about 59 degrees to about 70 or 71. Then I’ll set the thermostat down to 59 again and leave it until the next day. I realize most people would not like this setup, but I’ve purposely set it up this way simply to reduce the number of cycles. Going on 13 years with no failures and no service calls. Who can argue with this?
The carrier 58mtb100 but as I found out the blowers appear to go rather quickly. The heat exchanger works well but the blower died just about 1.5 months after 5 year parts warranty is expired. Planned obsolescense!!! I think next time I will buy a cheaper company and just save the money to repair them! I could have bought a similiar goodman furnace for half the price and had it run longer without problems.
"Should have kept the old 35 year old furnace"
The weather is getting cold so I turned the furnace on. I guess I shouldn’t have been surprised to find that again it is not working properly. It ran and blew a bit of heat for a very short time before it started making strange noises and blowing cold air only. We have had problems with this furnace since it was a couple of years old. We never needed a repair on the old original furnace that was in the house when we moved in. We’re on a first name basis with the repair man. He’s a nice guy but I’m getting tired of seeing him a couple of times each Winter. I would never buy a Carrier furnace 58MTA060-12 again. I do not like having a furnace I cannot depend on!
