The WeatherMaker^® Infinity 80 puts superior temperature and humidity control at your fingertips with intelligent electronics and variable speed operation.
Heating your home would be a simple proposition if winter weather would just stay a constant 32° all the time. Unfortunately it's not that easy. Conditions outside are always changing, making it a challenge for your comfort system to keep pace. That's the beauty of the Infinity 80 with ComfortHeat Technology and IdealHumidity.

The Infinity 80 offers low stage heating to gently circulate warm, comfortable air throughout your home. This "low speed" heating cycle operates nearly continuously to maintain your comfort with amazing consistency. Standard furnaces are limited to providing full-on heating, followed by full-off cycles and falling indoor temperatures. This results in up and down temperature swings, hot and cold areas in your home and periods of discomfort.

Variable speed operation helps the Infinity 80 conserve electricity all year long as a part of your complete indoor weather system. When you add a Carrier air conditioner, the Infinity 80 provides gentle and economical airflow during the cooling season. Low fan speed also allows you to run continuous fan all year long while using about the same amount of electricity as a 100-watt light bulb. Offering low fan speed for heating, cooling and continuous fan, this outstanding furnace contributes significant savings in electrical consumption all year long.

When it comes to your family’s comfort, you need to make smart choices. That means considering performance, efficiency, reliability and durability before investing in indoor weather equipment. With the WeatherMaker 8000VS, you’ll have all of those bases covered.

The Infinity 80 is the quietest model of our extra-quiet, 80% AFUE (Annual Fuel Utilization Efficiency) family of furnaces. Our engineers have been doing a lot of testing, and we've found that this model is the quietest 80% furnace in the industry during low-stage heating where it operates the majority of the time. That's the result of many subtle changes and improvements from previous designs. Quieter burner, inducer and fan operation are three major components of our QuieTech system, and three major reasons why you'll enjoy soothing, low-noise comfort.

When year-round comfort and energy efficiency are important, you can’t beat the Inifnity 80 gas furnace with ComfortHeat™ Technology. During the cold winter months, you can expect 80% AFUE (Annual Fuel Utilization Efficiency). When coupled with one of Carrier’s efficient air conditioning units, this gas furnace can deliver economical cooling well beyond what could be expected from an ordinary furnace. By running at a low stage operation 90% of the time, the Infinity 80 furnace provides consistent indoor weather and energy savings.

In fact, this furnace uses up to 60% less electricity than an ordinary furnace that constantly cycles on and off. The continuous air circulation of the Infinity 80 furnace keeps conditioned air moving throughout your home so you can enjoy consistent indoor weather. With 80% AFUE and up to 60% electrical savings over an ordinary furnace, the Infinity 80 furnace delivers exceptional energy efficiency while maintaining your comfort throughout every season.

In addition to providing consistent temperatures and energy-saving comfort, ComfortHeat™ Technology enhances the quality of the air you breathe. By providing “on” cycles that last 40% longer than those of an ordinary furnace, the Infinity 80 draws air through the furnace filter for longer periods of time to create a cleaner indoor environment. With the addition of a higher efficiency Carrier air filter, this system can provide superior air cleaning capabilities. Add that to the smooth, even comfort and miserly energy consumption and you’ll find that the Infinity 80 can be the cornerstone of an exceptional indoor comfort system.
