Carrier makes a lot of noise about keeping you comfortable, but be assured that the 58STA/58STX takes a more subtle approach. In fact, this model is a member of one of the quietest families of standard 80% AFUE furnaces available. To achieve such low noise operation, our engineers did their homework, digging deep into the old design, and making improvements in several areas. Burner, inducer and fan enhancements are the highlights of what we call our QuieTech system. Regardless of the details, we’re confident that you’ll be pleased with the results. These are the types of innovations that have earned Carrier a century of success.

Every home is unique, so we’ve developed a furnace that is so versatile, it feels like a custom fit even in the most challenging installation. With the previous generation of 80% AFUE furnaces were introduced, we were excited about offering a 40-inch tall cabinet. Now, with a redesigned heat exchanger, the 58STA/58STX stands just 33 1/3 inches to fit into even tighter spaces with room for an air cleaner or other accessory equipment. This model also installs in all four standard positions with thirteen venting options for less time-consuming installations.

You may ask yourself, "Why would Carrier take a proven design and make all of these changes?" The answer is simple. No matter how good a product may be, we can always make it better. That’s why Carrier is now, and always has been, the most innovative and respected name in the indoor comfort industry.

With the 58STA/58STX, you’ll benefit from everything that’s new, while enjoying that has remained the same: quality. Our philosophy on quality is this: it just takes one bad product to tear down a reputation we’ve been building for one hundred years. That’s why every product we create must pass through the most rigorous quality control program in the industry. From initial designs to had-built prototype units to completed units from the assembly line, nothing escapes the scrutiny of our quality testing. And, when we’re done, we’re confident that you’ll be satisfied with the comfort and reliability provided by your Carrier system.

1. Efficient, dependable startup is the result of using hot surface ignition. This feature eliminates the need for a pilot light to help save gas while improving reliability.
