The Carrier WeatherMaker 8000 Variable Speed Gas Furnace delivers ideal indoor weather. At Carrier, we understand that every home is different and every family has different comfort needs. That's why we designed the WeatherMaker 8000 Variable Speed Gas Furnace to respond to your precise indoor weather demands. Complete with variable speed technology, the WeatherMaker 8000 Variable Speed is an excellent choice for quality-conscious homeowners.

The WeatherMaker 8000 Variable Speed gas furnace offers maximum comfort and efficiency. Carrier's variable speed technology delivers remarkable comfort by providing longer, smoother and quieter heating cycles for a more consistent indoor temperature. Due to the different stages of heating, this variable speed gas furnace helps eliminate uncomfortable temperature swings as well as the hot and cold drafts caused by the on and off cycling of a standard furnace. The slower blower speeds help reduce operational noise and minimize electrical use so you can enjoy consistent, quiet, energy-efficient indoor weather throughout every season.

With its wide range of speeds and patented smart electronics, this self-adjusting furnace is designed to deliver customized comfort. Carrier's exclusive smart control board constantly monitors and adjusts furnace operation, controlling your indoor weather so you don't have to. This unique microprocessor also provides a memory of past heating cycles and automatically determines how the least amount of energy can generate the highest level of comfort. The WeatherMaker 8000 Variable Speed can even respond to increases in the humidity levels as part of a cooling system. All you have to do is set your Carrier controls and let the WeatherMaker 8000 Variable Speed gas furnace go to work for you.

The WeatherMaker 8000 Variable Speed gas furnace operates at a low stage of heating 90% of the time. This low-speed capacity ensures quiet operation and improved comfort far beyond what can be expected from a standard single speed furnace.

To match the sound generated by one standard 80% gas furnace, you would have to install approximately four Carrier WeatherMaker 8000 Variable Speed gas furnaces in your home. During the cooling mode, when the furnace fan is being used as an air handler, it would take up to ten WeatherMaker 8000 Variable Speed gas furnaces to equal the sound of just one standard furnace. The ultra quiet operation of the Carrier WeatherMaker Variable Speed offers enhanced year-round comfort.

In addition to delivering consistent performance and energy-efficient operation, the WeatherMaker 8000 Variable Speed is designed for long-lasting reliability and rugged durability. For example, the crimped seam construction of our Super-S heat exchanger is designed to resist corrosion. The hot surface ignition safely and reliably starts the aluminized steel burners, eliminating problems associated with standard pilot lights. Carrier's exclusive draft safeguard switch further enhances safety and reliability by automatically shutting down furnace operation if a common vent becomes blocked, preventing harmful flue gases from entering your living space. All of these added design features, coupled with the fact that this product is built in an ISO 9001 certified plant, ensure the quality and reliability of the WeatherMaker 8000.

Carrier's exclusive draft safeguard switch further enhances safety and reliability by automatically shutting down furnace operation if a common vent becomes blocked, preventing harmful flue gases from entering your living space.

Economical comfort is created by the two-speed inducer motor. This component ensures the proper flow of combustion gas through the heat exchanger for optimum heat transfer.

Energy-efficient performance of the WeatherMaker 8000 Variable Speed comes from our heat exchanger. Carrier's Super-S heat exchanger converts more than 80% of the heat from the furnace into useable heat for your home.

Optimum comfort and energy savings is the result of our variable speed blower motor. The continuous fan mode provides enhanced comfort and energy efficiency through improved air circulation and continuous air cleaning.

Quiet, consistent operation is due, in part, to the two-stage gas valve. This valve adjusts between high and low heating for consistent indoor weather and year-round comfort.

Maximum comfort and efficiency is controlled by a patented microprocessor which customizes furnace operation to deliver precise indoor weather.

Safe, clean indoor air is ensured by Carrier's exclusive draft safeguard switch that automatically shuts down furnace operation if a common vent becomes blocked.

When year-round comfort and energy efficiency are important, you can't beat the WeatherMaker 8000 Variable Speed gas furnace. During the cold winter months, you can expect 80% AFUE (Annual Fuel Utilization Efficiency). When coupled with one of Carrier's efficient air conditioning units, this gas furnace can deliver economical cooling well beyond what could be expected from a standard furnace. By running at a low stage operation 90% of the time, the WeatherMaker 8000 Variable Speed provides consistent indoor weather and energy savings.

In fact, this furnace uses up to 60% less electricity than a standard furnace that constantly cycles on and off. The continuous air circulation of the WeatherMaker 8000 Variable Speed keeps conditioned air moving throughout your home so you can enjoy consistent indoor weather. With 80% AFUE and up to 60% electrical savings over a standard furnace, the WeatherMaker 8000 Variable Speed delivers exceptional energy efficiency while maintaining your comfort throughout every season.

The flexible design and energy-saving operation of the WeatherMaker 8000 Variable Speed make this furnace an excellent choice for homeowners everywhere. Available for upflow/downflow and horizontal applications, the WeatherMaker 8000 Variable Speed offers maximum versatility for both new and retrofit installations. The 40-inch, three-way, multi-poise cabinet allows for easy venting and quick installations. The consistent performance, efficient operation and flexible design of the WeatherMaker 8000 Variable Speed make this furnace an exceptional way to start building your complete indoor weather system.

With a standard single-speed gas furnace, your temperature can fluctuate 4 degrees or more from your desired temperature setting. With the Carrier WeatherMaker 8000 Variable Speed, the two stages of heating help you maintain indoor temperatures within 1degree of your desired setting during every season.
