Coleman G9T Furnace Overview

The Coleman G9T is an Energy Star-approved gas furnace series ranging from 91 to 94.3 percent AFUE ratings. Models stand at 45 inches tall and are promoted by the manufacturer for their easy installation because of their compact size and simple wiring. Units can be configured for a two- or single-pipe venting.

Components of the G9T include tubular primary heat exchanger, stainless steel secondary heat exchanger, electric hot surface ignition and computerized control system with built-in self-diagnostics. Sound levels are kept low during operation with help from the induced combustion system and a PCS multi-speed, direct drive motor with a blower.

All units are protected by a corrosion-resistant, pre-painted steel cabinet and are equipped with add-ons for cooling products, with left or right connections and terminals for electric air cleaners or a humidifier.

Other G9T Reviews

Aside from very minimal troubleshooting issues, the G9T is the subject of few reviews across the web. While hvac-for-beginners.com rates units in this series well as basic units that are backed by a decent warranty, contractors on homeowner forums aren't as enthusiastic about this furnace. Some regard Coleman furnaces as fine standard equipment, but still recommend other brands that may offer higher performance and efficiency. Others simply state that the choice of unit may not be as important as the installation. As long as the G9T offers the right features for a homeowner and is installed correctly, these technicians say, the unit should offer consistent home heating.
