Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at (217) 342-6441 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Due to reasons beyond our control, lead times associated with appliances and parts may have unpredictable and fluctuating delivery dates.

What can you expect?


The Infinity® 80 gas furnaces include our Comfort Heat Technology® feature that accurately predicts the need for heating based on previous furnace cycles to effectively reduce temperature swings.


AFUE (Annual Fuel Utilization Efficiency) ratings are like your car's MPG - the higher the number, the greater the potential for savings. The Infinity® 80 gas furnaces delivery 80.0% AFUE heating and the potential for savings over an older, less efficient model you may be replacing.


The PowerHeat™ hot surface ignition is one of the most robust and durable ignition systems available. It eliminates the need for a pilot light, reducing gas usage and promoting more consistent operation.

Humidity Management

As a part of your home's cooling system, an Infinity® 80 gas with SmartEvap™ technology can be the key to enhanced comfort through precision humidity management. Include an Infinity System Control, humidifier and an Infinity outdoor unit and let Ideal Humidity System™ technology deliver improved comfort, all year long.

Hybrid Heat® System

Combining an Infinity® 80 furnace, an Infinity heat pump and an Infinity System Control, a Carrier® Hybrid Heat® system automatically switches between electric and gas heating to optimize the efficiency of each fuel source. It's a great way to help manage unpredictable utility costs.


Our variable-speed constant airflow blower distributes heated or cooled air at the lowest possible setting for the majority of the comfort cycle. Add our sealed combustion system and fully insulated cabinet and you'll enjoy warm, winter heating that's quieter than a conversation.
