Comfortheat™ technology is the ability to heat your home quietly and effectively by means of 2 stage or variable stage furnaces. This technology is designed to mimic the comfort of radiant heat by slowly churning warm air into the home with lower blower speeds and partial gas train utilization rather than the on again, off again, roar of an old-style single stage furnace.
Infinity™ technology integrates all of Carrier’s home comfort solutions. This 21st Century control technology is an industry exclusive and allows intelligent, overlapping control of indoor humidity, temperature, air quality, zoning, and scheduling, in addition to optional remote access of the entire system via the internet.
Carrier’s 80% AFUE furnaces are available in standard, single stage Comfortheat™ and the ultimate Infinity™ model. Prices on 80% furnaces can range from $1,400 to $3,500. Another consideration is that some installations require a flue liner at additional cost when the new furnace is vented into a masonry chimney.
Carrier’s 90+% AFUE furnaces are available from standard single stage, Comfortheat™ and the ultimate Infinity™ model. Some models of the Infinity 96.6% Carrier furnace meet requirements for federal tax credits. (see tax credit link on our links page) So much heat is removed from the combustion process and utilized to heat your home, that 90%+ AFUE furnaces are able to vent combustion gases through plastic pipe directly to the outside.
Another feature of a proper 90%+ installation includes utilizing outdoor air for the combustion process. This sealed combustion system adds to the efficiency of your home comfort system by not drawing warm air from the house and out through the flue. Don’t forget: air that is drawn out through your flue must be replaced by cold, dry outdoor air! 90%+ furnaces with properly installed combustion air pipe eliminate this loss of warmth and humidity from your home.
