Furnace Repair Glossary

Understanding common furnace terms can help you communicate effectively with HVAC technicians.

Furnace

A furnace is a heating system that heats air and distributes it throughout your home or business through ductwork. Efficient and properly sized furnaces are vital for indoor comfort.

AFUE (Annual Fuel Utilization Efficiency)

AFUE is a rating of how efficiently a furnace converts fuel to heat. Look for a furnace with a high AFUE for maximum savings on fuel costs. Modern high-efficiency furnaces have AFUE ratings of 90% or higher.

Heat Exchanger

A critical part of a furnace, responsible for transferring heat. It also separates combustion gasses from the air you breathe. Regular maintenance is essential to ensure its proper operation.

Blower Motor

The blower motor is the component in a furnace that pushes warm air. A properly functioning blower is vital for even heating.

Burner

The burner is the part of the furnace where the fuel (gas, oil, or propane) is ignited to generate heat. It plays a critical role in the overall heating process.

Pilot Light/Ignition System

Older furnaces use a pilot light, a small, continuous flame, to ignite the burner when the thermostat calls for heat. Modern furnaces more often use electronic ignition systems, which are more reliable and efficient. Problems with the pilot light or ignition system are common causes of furnace malfunctions.

Thermostat

The thermostat is where you set your desired temperature. Programmable thermostats allow you to set temperature schedules.

Ductwork

Ducts distribute the heated air. It's important to have your ducts regularly inspected and cleaned.

Filter

The furnace filter traps dust, pollen, and other particles from the air that circulates through your HVAC system, improving indoor air quality.. It's important to change the filter every 1-3 months.

Limit Switch

A safety device that prevents overheating if it gets too hot. Check this switch if your furnace is shutting down frequently.

Flame Sensor

The flame sensor ensures that the gas burners have ignited. If the flame sensor doesn't detect a flame, it will shut off the gas supply to the furnace for safety. A faulty sensor can trigger safety shutdowns.

Draft Inducer Motor/Fan

A key component of many modern furnaces, the draft inducer vents exhaust through the vent pipe. A faulty draft inducer motor can cause the furnace to shut down.

Capacitor

The capacitor is an electrical component that starts the motors. A failing capacitor is a common cause of furnace problems and may need to be replaced.

Control Board

The furnace's control board is the 'brain' of the system, telling it when to turn on and off. Problems with the control board can cause various issues, from inconsistent operation to complete system failure.

HVAC Technician

A licensed HVAC specialist trained to fix your system.
