A Carrier furnace is a gas or oil furnace used to heat the home that is available from Carrier, a brand of United Technologies. The brand offers a number of high-efficiency furnaces with varying sound levels and features.
As of 2015, Carrier's furnace collections include the Comfort, Performance and Infinity series, and the brand offers several Energy Star qualified gas and oil boilers with up to 96.7 percent efficiency. The Infinity series gas furnaces offer several condensing gas models for customers in varied climates, and the addition of Greenspeed Intelligence technology to the Infinity 98 59MN7 has earned it the Energy Star Most Efficient qualification. Performance series gas furnaces are built for maximum durability and efficiency, and the Comfort series gas furnaces offer relatively high efficiency while producing maximum heat to circulate throughout the home.
Carrier's Comfort series oil furnaces are some of the most affordable models available, and buyers can choose from a lifetime or 20-year limited warranty on the heat exchanger. The Performance series oil boilers are quieter than the Comfort series and have increased power and efficiency. All models are compatible with the Hybrid Heating system for more cost efficient heating. Other products available from Carrier include boilers, air conditioners, geothermal heat pumps, standard heat pumps and ductless systems.
