Common Types of Gas Furnace Repairs
On average, a gas furnace can last about 15 to 30 years, depending on how well you take care of it. Every furnace should be inspected and serviced at least once per year. Schedule this appointment before you turn on the heat for the first time each fall. During the inspection, the technician may notice that some components need to be repaired or replaced. However, you may sometimes need to call the HVAC technician for an additional appointment if your furnace isn’t operating as it should.
If you have a newer gas furnace, it might not have a standing pilot light. Instead, the modern furnaces feature hot surface ignition or intermittent pilot lights to begin the heating process. These methods are more efficient than standing pilot lights. When you turn up the thermostat, a pulse of electricity is sent through the igniter to start the furnace. The igniter is durable, but it will occasionally require replacement. Other common ignition system problems can include malfunctioning safety switches and computer boards, which an HVAC technician can replace.
If the ignition system appears to be working properly, the technician will then check the burner. The burner is the component that warms the air to be distributed throughout your home. If the burner isn’t working properly, it may be dirty or it may require an adjustment.
The blower is responsible for drawing heat from the furnace and pushing it through the ductwork to warm the entire house. At each annual inspection, the technician will lubricate the blower to keep it working properly and extend its longevity. However, if the blower has completely failed, it may need to be replaced. In some cases, a blower will run continuously and fail to shut itself off. If this happens, the technician will check the thermostat fan setting and either reset or replace the furnace fan limit control switch as needed.
