Furnaces become a large part of your home’s comfort when the weather gets cooler, but with them can come a variety of sounds. Most furnaces shouldn’t disturb your daily routine, but sometimes, various issues can make your furnace much louder than it should be. At Family Heating and Air, Inc, we understand how unsettling it can be when your furnace starts making unusual noises. Let’s explore some of the common reasons behind a loud furnace and why professional intervention is often the best course of action.
Common Causes of Furnace Noises
There are a number of different reasons that your furnace could be running loud or making noises.
Aging System
Over time, the mechanical components of a furnace, such as motors, fans, and blowers, undergo wear and tear. Bearings within the motor, crucial for smooth operation, can wear out, leading to grinding or squealing noises. Similarly, fan belts, which are integral to the operation of the blower, may become frayed or loose, resulting in a whining or buzzing sound.
Ductwork Expansion and Contraction
Ductwork in your home is typically made of metal, which expands when heated and contracts when cooled. When the furnace kicks in and warm air begins to flow through the cold ducts, the sudden change in temperature causes the metal ducts to expand.
Conversely, when the furnace shuts off and the air inside the ducts cools down, the metal contracts. This cycle of expansion and contraction can produce various noises, such as popping, banging, or creaking sounds, which are more noticeable during the start and end of the furnace’s heating cycle.
Blocked Air Vents
Sometimes, the culprit can be as simple as blocked or closed vents. Restricted airflow can cause the furnace to work harder, which may result in louder operational sounds.
Dirty Filters
The primary role of a furnace filter is to trap dust, dirt, and other airborne particles, preventing them from entering the furnace and the home’s air. Over time, these filters can become clogged with debris, leading to restricted airflow.
When airflow is impeded, the furnace must work harder to circulate air through the system. This increased effort can cause the furnace to produce more noise than usual, often a straining or humming sound, as it struggles to pull air through the clogged filter.
Faulty Heat Exchanger
The heat exchanger is subjected to constant heating and cooling cycles, which can lead to metal fatigue and the development of cracks or fractures over time. These structural damages can create various noises.
Air passing through a cracked heat exchanger can produce a whistling or hissing sound as the furnace runs. Additionally, if the crack causes a component to become loose, it may create rattling or banging noises, especially when the furnace starts up or shuts down.
