Carrier Furnaces

POWERFUL, PRECISION TECHNOLOGY FOR HOME FURNACES

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 motors 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 can also be paired with energy-efficient heat pumps that help to move ambient heat as opposed to burning fuel. 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 Furnace Heaters

When your search for new furnaces, keep in mind that not all models are created equally. Most forced air furnace models fall into two categories based on their fuel source -- natural gas furnaces 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 can decide between a natural gas furnace or heating oil furnace, consider the cost differences between the furnace itself as well as the price of natural gas versus heating oil - typically, oil furnaces cost less to install up front, but the cost of using natural gas for fuel tends to be lower over time. Your up-front furnace cost may be a once every 10-15 years occurrence, while the fuel source will be an ongoing monthly cost.

Condensing Gas Furnaces

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 CARRIER FURNACES 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.

Furnace Stages

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 - or in this case, to heat your home to your ideal temperature. 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.

High Efficiency Home Furnaces

You can compare furnace efficiency among models from different manufacturers using the furnace 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.

Whether you’re looking to buy a brand new furnace or you’re replacing a new furnace that is coming to the end of its lifespan, Carrier has the perfect heating solution for your home. Take a look at our buyer’s guide for furnaces and contact your local Carrier dealer for expert advice.
