CARRIER GAS FURNACE
Carrier's WeatherMaker Infinity delivers superior indoor weather with world-class efficiency.
Premium Gas Heating
Enjoy superior indoor weather with the industry's leader in conserving both gas and electricity - Carrier's WeatherMaker Infinity gas furnace. This technologically advanced heating machine combines Comfort Heat technology and gas-conserving components to heat your home at ratings ranging from 92.7% to 96.6% AFUE (Annual Fuel Utilization Efficiency). A smart microprocessor control center and variable speed motors minimize electrical usage during both heating and cooling operation. The resulting combination of gas and electrical savings makes the WeatherMaker Infinity the world's most totally efficient line of gas furnaces. With this extraordinary furnace, Carrier gives you the opportunity to experience the ultimate in indoor weather while minimizing use of the earth's precious resources.
Unmatched Technology
- Reliable, efficient burner ignition is the result of the Hot Surface
Igniter system. One of the most dependable ignition systems available, the hot surface
igniter conserves gas because there is no standing pilot.
- Comfort is improved because the two-stage gas valve provides two heating capacities. The low capacity increases comfort on milder days. The high capacity ensures comfort during extreme outdoor weather conditions.
 - Ultra-high efficiency performance and energy savings are provided by the variable speed inducer which precisely controls the amount of air drawn into the combustion system.
- Optimum comfort and efficiency is provided by the variable speed blower motor. This high efficiency motor provides maximum energy savings at low fan speeds during both heating and cooling. It also provides consistent airflow under varying load conditions and offers a continuous fan function for improved air circulation and air cleaning.
- Highly efficient, reliable performance is assured through the use of two heat exchangers. The primary heat exchanger extracts 80% of the heat from the gas you use, then the secondary heat exchanger extracts an additional 12% to 16%.
- More effective combustion takes place in the sealed combustion system. 100% outdoor air is used, eliminating drafts and discomfort associated with cold air infiltration while reducing operational noise as well.


Circulating Air Flow
Epoxy Coating Outside
Prevents the formation of surface oxidation.
Steel Substrate
Folded design easily permits the use of polypropylene lamination.
Polypropylene laminated inside
A moisture barrier which resists corrosion from water created by high efficiency condensing furnaces.
Corrosive Flue Gas and Acidic Condensate
Carrier's secondary heat exchanger with the patented Serpentuff polypropylene laminate resists corrosion for longer life.
Enjoy the comfort of consistent, economical and reliable indoor weather.
Temperature Control
ComfortHeat Technology means consistent indoor temperatures with a nearly continuous flow of heated air. One of the complaints with standard furnaces is that you're either too warm or too cold. That's because a standard furnace warms your home with a series of full-speed-ahead blasts of warm air. When the furnace isn't running, the temperature drops about four degrees before the next heating cycle. The WeatherMaker Infinity with ComfortHeat Technology maintains temperatures consistently close to your desired setting and can accurately predict the need for additional heating.
Under normal operation, the average fixed capacity furnace will consume about 625 watts of electricity. The WeatherMaker Infinity will use about the same amount of electricity as an 80-watt light bulb during low-capacity and continuous fan operation.
The WeatherMaker Infinity is easier on our natural resources and your monthly utility budget because it is a world leader in efficiency. This furnace saves gas with a draft-induced, sealed combustion system featuring two heat exchangers that extract up to 96.6% of the heat from the gas you use. To save electricity, the WeatherMaker Infinity relies on a smart microprocessor control center and variable-speed motors which deliver heating or cooling comfort using less energy than an 80-watt light bulb.
Reliable Performance
Winter after winter, you'll enjoy the comfort of the WeatherMaker Infinity because this furnace was built to last. Aluminized steel heat exchangers with no-weld construction resist corrosion. Hot surface ignition is one of the most reliable ignitor systems available. All of our dependable components are housed in a rugged, prepainted galvanized steel cabinet. Thoughtfully designed and solidly built, the WeatherMaker Infinity offers world-class comfort from the global leader in indoor weather: Carrier.
The WeatherMaker Infinity, with nearly continuous fan operation, improves air circulation for even, consistent temperatures throughout your home.
Standard furnaces produce a greater variation of temperatures, creating hot or cold spots as hot air rises to the ceiling and cool air falls to the floor.
