• Humming Sounds: While a dull hum is usually expected when a furnace is running, hearing a loud humming or buzzing sound is an indication of an electrical problem with the furnace. This problem is commonly caused by electrical issues, such as a failing capacitor of the blower motor, an aging or unlubricated blower motor, or a faulty transformer.

• Banging and Popping Noises: The cause of a loud banging or popping noise from your HVAC system can depend on when the noise occurs. If the noise happens during the start-up phase, it could be due to a delayed gas ignition issue. On the other hand, if the noise occurs while the system is running, it could be because of expanding or contracting air ducts.

• Squealing and Screeching Noises: Typically, a high-pitched squeal noise from your furnace indicates an issue with the blower. The blower is powered by a motor with bearings that can wear out due to overheating or old age, which is usually caused by dirt buildup or a damaged capacitor. In contrast, a high-pitched whistling or screeching sound is usually a sign of a low airflow issue. This means that the blower is having difficulty drawing in sufficient air to heat. Common causes of low airflow include obstructed or closed air vents, dirty or damaged ducts, and a dirty air filter.

• Scraping Noises: Scraping noises coming from your furnace can be caused by issues with the blower wheel. If left unaddressed, this can cause significant damage to your furnace.

• Clicking Sounds: When you hear a clicking noise coming from your furnace, it is likely due to an issue with the ignition system, which is responsible for creating heat through combustion. If the furnace is struggling to ignite, the igniter may produce clicking sounds. There are several common ignition problems that could cause this issue, including a faulty ignition board or valve preventing gas from reaching the system, dirty burners, a broken flame sensor, or an extinguished pilot light or broken thermocouple in older furnaces. However, a loose fan motor bearing can also cause a clicking noise.

The Scariest Furnace Problems Can Be Silent

In addition to unusual noises, your furnace may also have issues that are not as noticeable, such as a carbon monoxide leak. Carbon monoxide is a toxic gas that is both odorless and colorless, making it difficult to detect without specialized equipment. A crack in the heat exchanger can cause carbon monoxide poisoning, which can result in symptoms like dizziness, nausea, and fainting. To avoid these dangers, it's essential to schedule regular furnace maintenance services with our team each season. Additionally, you should ensure that your carbon monoxide detectors are always in working order to stay safe.
