How a heating system operates
- Quiet Direct-Drive Multi-Speed Blower Motor--Provides quiet operation with no pulleys or belts to break.
- Optional Electric Heat--A wide range of electric heat options are available including the EvenHeaterT Supplemental Heater to provide backup resistance heat.
- High-Efficiency Evaporator Coil--Provides exceptional heat transfer and refrigerant flow for efficient operation.
- Efficient Check and Expansion Device--Ensures efficiency is provided over a large variety of operations.
- Easy Filter Access--Tool-free filter access makes it easy and convenient to change filters for high efficiency.
- Quiet Operation--Insulated blower compartment and cabinet, combined with quiet blowers, help mute sound levels.
- No External Side Screws--Eliminates scraping walls or doors, no matter how tight the space.
- High Static Capability--Airflow can be adjusted to meet any home's comfort requirements.
- Compact Size & Convertible Airflow Design--Enables the Elite 10 and Elite 12 blower coils to be installed almost anywhere. Available in up flow, down flow, horizontal and side return applications.
- Corrosion-Resistant Cabinet--Durable, baked-on enamel finish protects the heavy-gauge, galvanized steel cabinet against rust and corrosion.
- Multi-Position Plastic Drain Pans--Guard against corrosion and prevent leaks and water damage.
Central City Air uses Lennox, Maytag and American Standard residential furnaces that use either natural or liquefied petroleum (LP) gasses or electricity as their source of fuel.
The heat section of a gas (either natural or LP) furnace consists of a steel heat exchanger and gas burners. The burners fit into a cavity at the bottom of the heat exchanger. Gas is fed into the burners and ignited by a pilot flame, or electric ignition device, after receiving a call for heat from the room thermostat. The burning gas warms the heat exchanger, and the furnace blower distributes the heat through the duct system to the living areas of the home.
The heat section of an electric furnace consists of one or more electric heating elements. The element is much like that in an electric toaster, only larger. When the room thermostat demands heat, a resistance to flow of electricity in the element produces heat. The heated air is moved by the furnace blower through the ducts and distributed to living spaces in the home.
