Common Furnace Problems

A gas furnace provides warmth and comfort on those chilly winter nights in Carrolton, GA. You have made a significant investment in your HVAC system, so when it breaks down, it is important to hire a qualified HVAC contractor who can quickly locate the problem and make the required repairs. A malfunctioning furnace during the heart of winter poses many problems. Depending on the age of your furnace, and whether it has been receiving proper care and maintenance, most issues likely have relatively simple solutions.

Pilot Light Malfunction

The pilot light is a critical part of the gas ignition process. Older systems use a manual pilot while newer furnaces incorporate an electronic ignition device. Pilot light problems are usually caused by:

Lack of Heat

If there is no heat coming out of the supply registers, the issue may involve a gas valve or the thermostat. In some instances, the gas valve may close unexpectedly during operation. This inhibits the flow of gas into the combustion chamber, which shuts down the heating process. Thermostats with a manual changeover can be the source of heating problems if they are not switched over to the heating mode when the seasons change.

The Blower Won’t Shut Off

A blower that won’t shut down could be the result of the thermostat or a faulty fan switch. Some homeowners inadvertently set the thermostat fan setting to the “on” position, which causes the blower to run constantly. The control must be switched to the “auto” position so that it only runs during the heating cycle. If the control switch is broken, it will need to be replaced by a qualified HVAC technician.
