Carrier Infinity® Condensing Gas Furnace

The Carrier Difference

How is it Carrier Infinity furnaces achieve such an impressive 98.5% efficiency? Inside of a furnace, Natural gas is burned to increase the temperature of a heat exchanger which then has air blown over it, transferring energy to the air that will be distributed throughout your home. In a non-gas-condensing furnace, a great deal of useful heat simply leaves your home through the chimney. A gas condensing furnace on the other hand is designed to capture all the "waste" heat and turn it into functional heat. The process is essentially the same, except gas condensing furnaces have an additional heat exchanger. When air is passed over the first heat exchanger, it creates hot water vapor as a byproduct. This water vapor is then redirected to the second heat exchanged to ensure that as little heat escapes the process as possible. This process is so effective that the exhaust gasses are cool enough to exit your home from a PVC plastic chimney.

  Another crucial difference between a state of the art furnace like the Carrier Infinity and a run of the mill 80% efficieny model is "variable-speed" operation. A "single-stage" furnace has only two modes, on and off. This means that the furnace will operate until it detects that a temperature set point has been reached and then shut off entirely. When the temperature decreases, enough it must be turned on again. This cycle can result in noticeable temperature fluctuations. Carrier Infinity furnaces are equipped with a modulating gas valve that can be adjusted up or down in 1% increments so that the furnace is always operating at a level that matches your heating demand.

 Infinity: Putting you in Control

The Carrier Infinity® controller enables home owners to regulate the operation of their furnace and therefore the temperature and humidity of their home at a highly granular level. This simple wall mounted controller allows the user to set custom temperature and humidity settings for different times of day and up to 8 different areas of their home. Advanced smart setback automatically selects the optimal energy efficiency settings to minimize your energy consumption while you're away and transition to your desired comfort level by the time of your return. The Infinity® controller is occupancy sensing, ensuring that the furnace provdes heating only when and where it's needed, further reducing your energy consumption. For those who want an optimal energy saving configuration but aren't interested in managing the system personally, the controller is capable of operating on autopilot. On autopilot the system will actively make adjustments for maximum efficiency and comfort, no input from the user required! Rather than wait for your monthly bill, the Infinity ® controller monitors and records your energy use in real time and enables you to further lower your utility bills with appropriate system adjustments. The system is compatible with Amazon Alexa and CôR® Smart home technologies, and it can be accessed from anywhere using the MyInfinity mobile app.

 Hybrid Heat: Best of Both Worlds

A Carrier Hybrid Heat system combines the cold weather heating capabilities of a codensing gas furnace and a heat pump which is exceptionally efficient when the outdoor conditions are more temeperate. As the temperature dips, it can quickly become more effective to heat your home using a gas furnace. On the other hand, as the temperature rises, heating loads may be met far more efficiently using a heat pump. A Carrier Hybrid Heat system combines a Greenspeed heat pump and gas furnace, which in tandem with the intelligent Infinity controller, will automatically select which appliance is best suited for a given heating load using real time temperature and utility price data.  This guarantees that your home will stay comfortable even on the coldest of days while reaping the benefits of the extreme efficiency of a heat pump when the weather is warmer.
