Fraser-Johnston

At last, home heating performance that hits your comfort level--day in day out, season after season. And when a Fraser-Johnston® furnace is properly matched with a Fraser-Johnston air conditioner or air handler, you will enjoy extended system life and maximum efficiency all year around!


Here's how it works:
Furnace design has advanced in recent years to be far safer and more efficient than older designs. This is the result of improvements in the burner, the ignition, and the blower motor. Furnace heating efficiency is measured by an Annual Fuel Utilization Efficiency (AFUE) percentage. A higher AFUE percentage indicates a more efficient furnace.


The basic components of a furnace system are:
A burner, where gas (natural or propane) or oil is delivered and burned
An ignition source, which is typically an electronic hot surface igniter that supersedes the old-style pilot light
A heat exchanger, where the heat from the burning gas is transferred to the air distribution system
Blower motor, such as the highly efficient electronically commutated motor (ECM) to propel air through the ductwork
Filtration and ductwork to circulate clean, warm air throughout the home
A flue or vent pipe to exhaust by-products of combustion (such as water vapor and carbon dioxide) outside. High-efficiency furnaces use special, corrosion-resistant vent-pipe materials.
