Furnaces are the most common residential heating system in the U.S.
A traditional home comfort system has two parts: an outdoor unit, such as an air conditioner and an indoor unit. The furnace is the indoor unit that heats and circulates warm air through your home in the winter, and in the summer works as a fan to circulate the cool air provided by your air conditioner. The indoor and outdoor units are designed to work together. And when the furnace is properly matched with an air conditioner, the result is maximum efficiency and extended system life. Furnace heating efficiency is measured by the AFUE%. The higher a AFUE percentage, the more efficient the furnace is.
The basic components of a furnace system are:
- A Burner, through which gas (natural or propane) is delivered and burned.
- A Heat Exchanger, where the heat produced from the burning gas is transferred to the air distribution system.
- Ductwork, to transfer the heated air throughout the home.
- A Flue or Vent Pipe, to exhaust byproducts of combustion (such as water vapor and carbon dioxide) to the outside.
A gas furnace uses natural gas or propane. Even though it is a gas furnace, an electricity source is still required to run the control systems, blower and accessories.
We offer a wide variety of gas furnaces in different sizes and efficiencies.
Variable-speed furnaces circulate air throughout the home for longer periods of time, reducing air stagnant air. These longer run cycles can improve air quality by increasing air filtration. Variable-speed furnaces offer significant operating cost savings and whisper quiet operation. Variable-speed furnaces also feature an ECM blower motor that uses less electricity than a 100 watt light bulb. Standard furnace motors usually use nearly 500 watts.
These furnaces feature two-stage operation with electric hot surface ignition and an induced combustion system for quiet, efficient operation. Two-stage furnaces operate at low capacity during most of the operating cycle to maintain your comfort. On bitter cold days, the second stage is there to maintain comfortable temperatures.
Single Stage Furnaces
Single-stage furnaces offer many new features not found on older furnaces. One feature is an inducer that draws the correct quantity of combustion air into the furnace for the most efficient operation possible. Another is an electronic ignition system that replaces the old wasteful pilot light. A third is a powerful, direct-drive blower that sends warmth to all the rooms in your home. These features will help make your home more comfortable, while reducing your heating fuel bills.
