What is the most common furnace problem? 

Furnaces are designed to provide extreme heat. They are used in residential as well as commercial areas. Common furnace problems require immediate inspection. If not treated on time, minor furnace troubleshooting can become a costly maintenance problem to deal with. 

Ignition issues (Pilot light issues)

Pilot lights are considered an important part of the furnace. When noticing flickering in the light or the yellow light instead, the furnace needs expert assistance at that very moment. 

Old furnaces have a pilot light, while the new models have electrical ignition. Both do the same work. And need immediate assistance when not work properly. 

They are only to be trusted by an expert, as pilot lights indicate that the rest of the furnace is working properly, the gases are being released, and the charge is there. The furnace is unable to produce heat and sometimes produces cold air, which is due to the pilot light and needs to be corrected by the professionals.

Heat Exchanger Failure

Heat exchanger failure is one of the common furnace problems, but a costly issue, as it happens due to the excessive use of furnaces. When the furnaces are overheated or the air replacement filters are not active, the heat exchanger could fail. 

This creates a crack in the heat exchanger, which is extremely dangerous and requires immediate attention. The carbon monoxide gas slips through those cracks, which is harmful to human health. 

Air filters clogging

This is one of the common furnace maintenance problems that gets neglected. Air filters need regular inspection so that they can be cleaned and work efficiently. 

Long ignorance of air filters can lead to the buildup of dirt and contamination. Air filter clogging can lead to many downstream issues, like damage to the limit switch. 

Vlogged air filters hinders its efficiency and performance, which can lead to higher utility bills as it will take more energy to work. Sometimes it causes a complete shutdown of the furnace to prevent overheating.

Short cycling

Short cycling is the process in which the furnace starts turning on and off rapidly on its own. This happens due to clogged air filters, poor airflow, or thermostat malfunction. This is the most common furnace problem that requires HVAC furnace repair. 

It can further lead to many more problems, and obviously, the frequent turning on and off of the furnace takes more energy and causes higher electricity bills. Consult an HVAC furnace repair professional for immediate action.

Problematic Thermostat

Thermostat malfunction is also common furnace problem when the controller of the furnace needs to be repaired. There can be a gap in communication between the Thermostat and the furnace, which causes poor performance of the furnace. 

The thermostat issue could be due to battery issues, a dead battery, incorrect settings, wiring issues, or loose wires. The thermostat battery will be running, but the furnace will not be working properly.

Malfunctioning of the blower motor

The blower motor is the motor that gives power to the fan, which generates warm air for the home. When the blower motor is affected, it will cause the fan to not work properly and cause the furnace to blow cold air. 

Checked for a tripped circuit breaker and a blown fuse. In such cases, it is not an issue and can be treated instantly.

This malfunction could be caused by a clogged blower motor, or there could be a technical issue with it. A professional is required in either case.

Unnecessary noises

 Working furnaces are generally quiet. If you are hearing squealing, cracking, popping, or any sort of sound, it indicates the presence of a technical issue. Sometimes the sound is also due to the expansion and contraction of ductwork. An expert’s attention is required in such cases.
