8 Common Problems With Conventional Gas Furnaces

According to our furnace service experts in Olney, MD, it is essential to tune up the furnace system to ensure it runs optimally and swiftly without consuming much of its resources. However, the gas consumption of the furnace will increase if issues are built into the system. You need to detect and quickly resolve the issue if you want to prevent high utility bills.

Common problems that you may have to face with gas furnaces

Here are some problems that the furnace may develop in the long run: 

  • No heat and inefficient heat

    It is best to check for leaks in the ductwork because air can escape from the outdoors, leaving your room cold. You can check the thermostat settings and replace the air filter to fix the airflow. Ensure that the air vents in your household are secured by furniture or massive objects. Check all the power switches and circuit breakers to ensure the system gets power. 

  • Short cycling issue

    Occasionally, the furnace system may start acting strangely, and it starts and stops abruptly. According to our furnace repair experts in Olney, MD, it can be due to a blocked exhaust vent, a clogged air filter, or a faulty thermostat connection. Ensure to address the issue at the earliest possible time, as it can increase the furnace’s load to keep the optimum environment. 

  • Constantly running blower

    A perfectly working furnace system takes a break of 5-10 minutes before resuming its work. However, there might be a leakage issue or a fan limit switch problem if the blower runs continuously. The blower can run continuously if the thermostat is adjusted to fan settings. 

  • Loud and disturbing noises

    If the furnace makes loud noises, it may be a sign that you must schedule a maintenance visit. It may also indicate an issue building inside the system if you hear strange and weird noises like bubbling, screeching, or thumping.  

  • No igniting pilot light

    Your furnace will only produce heat if you can see the pilot light igniting. A pilot light in older furnace models helps ignite the combustion process. A pilot can go out due to a dirty pilot burner, a blockage in the gas tube, a faulty thermocouple, or a strong draft. 

  • Malfunctioning electronic ignition

    Electronic ignition systems help ignite the gas by producing a high-voltage spark when the thermostat calls for heat. Malfunctioning electronic ignition systems can affect the furnace’s work, and you may receive inefficient air. Short cycling issues can be due to faulty electronic systems. 

  • A thermostat is incompatible with the furnace

    You may need help to operate the furnace system if you have bought a smart thermostat to operate an older model of the furnace system. The furnace might overheat or underheat regardless of the thermostat settings. Consult our furnace technician service in Olney, MD, before buying a thermostat. 

  • Thermostat issues

    The thermostat can be responsible for the abrupt functioning of the furnace system. Ensure the fan is in automatic mode and no dust accumulates on the thermostat’s surface. Check the connection of the thermostat with the furnace system. Call the technician to fix the issue if there is any loose wiring.

To summarize

HVAC problems can affect the furnace system’s functioning and degrade its performance. According to our furnace service experts in Olney, MD, it is best to call the technician to repair the issues to maintain the system’s efficiency.
