Product Overview

The furnace is characterized by its Greenspeed® Intelligence, Carrier’s proprietary technology that adapts to your specific needs, adjusting heating output in minor 1% increments. This allows for exceptional comfort, as the furnace can operate for longer at lower, more efficient settings, providing more consistent heat distribution without the temperature swings associated with traditional furnaces. The unit is remarkably quiet, operating at a sound level as low as 58.7 decibels, which is quieter than a normal conversation. This is due in part to its variable-speed, ECM blower motor that mitigates noise, ensuring a peaceful home environment. Ease of use is another area where the Infinity® 98 Gas Furnace stands out. The Infinity® control system provides direct access to system diagnostics, maintenance reminders, and wifi connectivity for convenient control from anywhere in your home or remotely via a smartphone. In terms of reliability, this model is built to last, following Carrier’s tradition of durable products. The primary and secondary heat exchangers are made of aluminized steel for corrosion resistance and long-term performance. The unit’s compatibility with the Hybrid Heat® system also adds versatility, allowing it to work with an electric heat pump to optimize comfort and efficiency.

While no product is without its potential drawbacks, it’s hard to find fault with the Infinity® 98 Gas Furnace. It is a premium product, so the initial price may be higher than other models on the market. However, the potential energy savings, robust features, and longevity of the unit should offset the initial cost over time.

The Infinity® 98 furnace delivers precision comfort with Greenspeed intelligence. This is the most advanced Carrier® furnace ever made. Its unique design innovations achieve unprecedented efficiency and quiet. Greenspeed intelligence is created by pairing adaptable-speed technology with Infinity controls’ intelligence. The unique, modulating gas valve of this unit, when managed by the Infinity control, allows it to adapt its output to the needs of the home. With tiny, 1% adjustments between 40 and 100% capacity, it gives the home only the amount of heating necessary.

This allows the furnace to operate longer at steadier, lower capacities, which ensures incredible energy efficiency and quiet operation with tighter temperature control than standard furnaces.

Variable-speed blower operation is a part of the Greenspeed equation while also enhancing other system components. It’s an outstanding choice for potentially boosting air conditioning system efficiency and improving summer dehumidification.  Learn more about our amazing Greenspeed intelligence units in the Innovation section.
