Maintaining your furnace is critical to keeping your home comfortable and energy efficient. Unfortunately, furnaces can deteriorate over time, leading to a decrease in performance, higher energy bills, and potentially costly repairs.

Understanding the signs of furnace deterioration can help you take steps to keep your furnace in tip-top shape and ensure that your home remains comfortable and energy efficient. But when the furnace system starts vibrating, it is a different concern homeowners should look into.

1. Loose Parts

The most common cause of furnace vibration is loose parts, which can occur due to wear and tear. Inspect the furnace regularly to ensure that all screws, brackets, and other fasteners are secure and far from being loose parts.

The blower motor is the heart of your furnace. It helps push the hot air produced through the ducts into your home. Unfortunately, if the blower motor malfunctions, you may experience poor airflow, loud noises, and inconsistent temperatures.

If the motor is still functioning correctly, then it is likely that the problem lies within the blower motor’s wiring. Therefore, then it is essential to have an experienced HVAC technician take a look to help determine the issue and make necessary repairs as needed.

2. Foreign Item Inside

If you notice that your furnace is making an odd noise or has stopped working, something may get stuck inside. Foreign items such as small toys, dirty filters and other items, can get sucked into the system and cause it to malfunction.

If you suspect something may be stuck inside your furnace, it is essential to turn off the power and call an HVAC technician. An experienced technician can determine if something is stuck and safely remove it from the system.

3. Disconnected Duct

If the air from your vents is not the same temperature as the rest of your home, it may be because the ducts are disconnected, caused by various things, including a poor installation job, or disconnection through renovations.

If you suspect your ducts are disconnected, you must call an HVAC technician immediately. They can inspect the vents and determine if there is a connection issue. If so, they can repair or replace the ducts as needed.

Why Is Furnace Maintenance Important?

Furnace maintenance is essential because it helps ensure your furnace runs efficiently and safely. Regular maintenance can prevent costly repairs and breakdowns. It can also help extend your furnace’s life, preventing people from replacing their systems too early. Additionally, regular maintenance can help to improve air quality in your home, as a well-maintained furnace will not emit as much dust and other particles into the air.


A vibrating furnace is a typical issue for maintenance contractors in an HVAC system. It can cause the furnace to vibrate more than average, leading to increased energy costs. Therefore,  it is essential to regularly inspect the furnace and clean it out as needed, preventing problems from arising.
