95.1% AFUE Variable-Speed/
Two-Stage Gas Furnaces

This furnace delivers up to 95.1 AFUE rating which means that the furnace functions at or above 95% efficiency, one of the highest ratings available on gas furnaces today.

Features & Benefits

ECM Motor: Energy efficient brushless DC (ECM) motor gives up to 1 SEER point efficiency gain in cooling.

2 Stage Inducer: Optimizes efficiency on first stage heat and reduces sound levels.

100% Fired and Tested: All units and each component (both mechanical and electrical) are tested on the manufacturing line.

Low Boy Height: Easy to apply in low ceiling applications, works well with taller high SEER coils.

Tubular Primary Heat Exchanger: Heavy gauge aluminized steel heat exchanger assures a long life.

30 Second Blower Delay at Start-Up: Assures warm duct temperature at furnace start-up. Adjustable
blower off settings (60, 90, 120, and 180 seconds)

30 Second Post Purge: Increases life of heat exchanger.

Hot Surface Igniter: Silicon Nitride Igniter. Utilizes Smartlite technology.
SmartLite® Control Board: Exclusive Patented technology, SmartLite learns the igniter's heat-up characteristics then adapt the ignition time to the furnace characteristics. As a result, the igniter is energized appropriately, extending the life of the igniter.

High Static Blowers: All models equipped with high static blowers.

Flexible Category IV Venting System: May be vented with vertically or horizontally, using either a one-pipe or tow-pipe system for maximum flexibility in installation.

Diagnostic Lights for Easy Troubleshooting without Counting Flashes: Dedicated light for flame signal strength and 2 lights in combination to indicate all other fault codes..

Fully insulated blower cabinet for quiet operation.

Best Packaging in the Industry: Unique design assures product will arrive to the homeowner dent-free.
LP Convertible: Simple burner orifice and regulator spring change for ease of convertibility.

Warranty - 10 Year All Parts: 20 Years on Heat Exchanger, (w/ consumer registration)

10-Year Quality Pledge: Replacement of entire heater if the heat exchanger fails in the first ten years, (w/consumer registration)


92.1% AFUE Variable-Speed/
Two-Stage Gas Furnaces
These Gibson furnaces are different than basic gas furnaces because they use two-stage, variable speed technology to provide more consistent and energy efficient comfort throughout your home.


80% and 92.1% AFUE Fixed-Speed/
Single-Stage Gas Furnaces
Like all Gibson products, these furnaces are built using proven components for reliable performance. A fixed-speed, single-stage product is designed to meet basic heating needs, with the best value. Some models are also available in our compact size for tighter spaces. The contractor will recommend the furnace that will meet your efficiency and installation needs.



80% AFUE Fixed Speed/
Two-StageGas Furnaces
What makes this Gibson furnace different than the basic gas furnaces is the two-stage technology it uses to provide more consistent comfort throughout your home. During the first stage, which is about 80% of the time, the unit will use about 68% of its heating capacity. It will always start in the first stage and attempt to meet the heating demand. This reduced capacity is enough to efficiently warm your home on mild winter days. When the temperatures drop the furnace automatically adjusts itself and enters the second stage to meet the increased heating demands.

80% AFUE
Variable Speed/
Single-Stage
Gas Furnaces
Under normal operating conditions, a Gibson single-stage variable speed furnace ensures constant comfort because the motor will automatically maintain its programmed level of airflow. Better indoor-air quality can be achieved quietly and inexpensively when set to run continuously. In fact, if you run your thermostat in continuous fan mode, your electricity consumption will be reduced from 500 watts to 65 watts over a furnace that has a standard blower. Variable speed blowers are readily available in the most popular Gibson models but it can also be added during installation to almost any model.


All Gibson furnaces are built using proven technology and reliable components protected by our heavy-gauge, scratch-resistant cabinet. The SmartLite® control board used on all of our gas furnaces helps extend the life of igniters in furnaces using hot surface ignition technology.
