5 Common Causes Of Furnace System Failure


Although a furnace is a quick and effective way to heat your home when temperatures start to drop, it can develop problems that can cause it to fail, leaving you at the mercy of the biting cold. Here are five common culprits behind furnace system failure. 

1. Faulty Thermostat

Thermal comfort means different things to different people, and many personal and environmental factors affect it. Like other homeowners, you have specific temperature requirements and preferences for thermal comfort. A properly functioning thermostat is central to maximizing the warmth and comfort your furnace system provides as it allows you to regulate your indoor temperatures. If it breaks or malfunctions, it can cause the furnace to cycle on and off too frequently or not turn on at all. When this happens, the heating system may not achieve the desired indoor climate for your home.

2. Leaky Ductwork

Furnace systems are also referred to as ducted heating systems because they use a network of ducts and vents to distribute the heated air throughout your home. Over time, the air ducts can develop leaks due to old age, lack of maintenance, or rodent damage. If not detected and addressed in time, these leaks can cause a significant loss of heated air, resulting in inadequate and inefficient heating performance. 

3. Filthy Air Filter

Air filtration is critical to forced-air heating as it ensures the heated air is clean and healthy for building occupants. That said, your furnace system's air filters are bound to become dirty over time and will need to be cleaned or replaced. Otherwise, they can impede airflow through your heating system and cause it to work unreliably and inefficiently. Dirty air filters can also trigger allergies and worsen the respiratory conditions of your household members.

4. Dirty Ductwork

Filthy air filters are not the only factor that can lead to reduced heating output and reduced indoor air quality. The dust and dirt that infiltrates your ductwork over time can block and contaminate the air coming out of your furnace heating system, compromising heating performance and the health of your family. 

5. Faulty Pilot Light

If the pilot light malfunctions, the furnace won't burn fuel to heat your home. As a result, you may feel air coming out of your vents, but it's not warm.

Accurate and timely diagnosis is essential to ensure effective repair of furnace issues. Contact a local furnace repair service to learn more.
