If you could look under the hood of a Carrier gas furnace, you’d see what drives the performance: a serious commitment to precision technology and quality. Depending upon the model, you might find a modulating gas valve that can be adjusted up or down in 1% increments. Models with variable-speed blower and inducer motors can deliver consistent temperature control all year long and enhanced humidity control as a part of your air conditioning system. Our 90+% AFUE rating gas furnaces include two heat exchangers -- a primary heat exchanger that does most of the work and a secondary heat exchanger that wrings out additional heat for higher efficiency and comfort. And, for reliable start-up and heating operation, all models feature our patented PowerHeat™ igniter.
Additional comfort enhancing functions on select models include Ideal Humidity System® technology for relief from hot and sticky summer air and ComfortFan™ technology, which allows you to select furnace fan speeds from the Infinity System Control. Carrier furnaces combine quality and performance in a durable, attractive and compact cabinet. And if the mention of “compact cabinet” prompts you to ask yourself, “What size furnace do I need?”, you’re in luck! Your local Carrier expert can properly size and install the Carrier gas furnace that makes the most sense for you.
Types of Forced Air Furnaces
When your search for a new furnaces starts heating up, keep in mind that not all models are created equally. Most forced air models fall into two categories based on their fuel source -- natural gas or oil furnaces. And in most cases, the decision between natural gas or heating oil is already made for you based on the fuel source available for your home. If you have the ability to decide between a natural gas or heating oil furnace, consider the cost differences between the furnace itself as well as the price of natural gas versus heating oil. Your up-front furnace cost may be a once every 10-15 years occurrence, while the fuel source will be an ongoing monthly cost.
All furnaces include a heat exchanger, which converts combustion gases into heat for your home. Condensing models employ a secondary heat exchanger which squeezes additional heat from combustion gases to achieve 90% or better AFUE efficiency. Most standard models with one heat exchanger deliver around 80% AFUE efficiency.
Can My Furnace Heater Use Propane?
Many of the Carrier gas furnaces currently available can be converted for use with propane. The process includes replacing burner orifices, installing spoiler screws, installing a low gas pressure switch and making several additional adjustments. This is a job for your local, professional Carrier HVAC expert, and definitely not for the average home DIYer.

Today’s forced-air furnaces are available in single-stage, two-stage or multi-stage models. Think of heating stages as gears on a bicycle or a car. Single-stage models are like a bicycle with one gear. It’s great on a flat stretch of road, but takes a lot more energy to go up a steep hill. Two-stage models add a second gear, one to handle everyday heating needs, and a second gear to provide additional heating as needed. Multi-stage, or modulating stage furnaces are like cruise control on your car, adjusting up and down as needed to provide comfort and efficiency as weather conditions change.
Furnaces for Any Home – Any Budget
When you turn to the Carrier experts for your home heating system needs, you’ll find a comprehensive selection of natural gas and oil furnaces designed to fit any home and nearly any budget. Of course, the cost of a new furnace often reflects the comfort benefits, performance and length of warranties. For those who enjoy the best of the best, our premium, Infinity® series models deliver the highest efficiency and the most innovative comfort features we offer, quieter operation, and enhanced summertime humidity control as part of your home air conditioning system.
If you like premium perks at a more modest price, our Performance™ series models deliver the best of both worlds. If you are cost-conscious, our more budget-friendly Comfort™ series units can still achieve high efficiency with all of the built-in quality, support and backing of the inventor of modern air conditioning – Carrier.
High Efficiency Furnaces
You can compare furnace efficiency among models from different manufacturers using the AFUE rating -- the higher the AFUE, the better the efficiency. Current high efficiency furnaces can be rated up to 98.5% AFUE, which can reduce utility costs over the life of the furnace. In many cases, our Carrier high efficiency furnaces also include technology that can produce enhanced comfort benefits and quieter operation as well.
