Feeling your floor vibrate when the furnace operates can be disconcerting and raises questions about the safety and efficiency of your heating system. This article explores the common causes behind these vibrations, from furnace mechanics to potential issues. We’ll also provide practical insights and solutions to help you identify and address the root of the problem, ensuring a more comfortable and secure heating experience.
Let’s take a close look at what causes your floor to vibrate when the furnace starts.
1. Unbalanced Blower Wheel
When your floor vibrates as the furnace starts, the unbalanced blower wheel might be the culprit. This imbalance can lead to unwanted furnace noise and shaking when your furnace turns on.
- The blower wheel in your furnace can become unbalanced due to the accumulation of dirt, debris, or dust. Irregular wear over time, without proper maintenance, may contribute to this imbalance.
- As a result, the furnace may experience reduced efficiency and increased strain on its motor, leading to a greater potential for audible vibrations and noise during operation.
- To help stop furnace noise and shaking, regularly clean the blower wheel to prevent the accumulation of dirt and debris. Additionally, we recommend scheduling routine maintenance with Orzech to address wear issues and ensure proper balance.
2. Loose Ductwork
Loose ductwork can magnify why your floor vibrates when the furnace turns on, causing a noticeable problem. Given that electric, natural gas, and propane furnaces all use ductwork to circulate heat around your home, loose ductwork is a common issue that causes furnace noise and shaking. Here is how loose ductwork can contribute to floor vibration:
- Expansion and contraction of ducts due to temperature variations can lead to loose connections in furnaces. Improper installation or aging of ductwork components may also contribute to this issue.
- The furnace may produce increased noise and vibrations as air is forced through the loose ducts, leading to reduced energy efficiency, furnace noise and shaking.
- It could also be time to replace your ductwork!
- If you are confident in your DIY skills, you can inspect ductwork regularly for signs of wear and loose connections and secure loose ducts with appropriate fasteners. If you aren’t experienced with ductwork, professional ductwork maintenance is your best bet for reducing furnace vibrations. Orzech can take a look at your ductwork for you, to make sure that it’s in tip-top shape, and ensure that you don’t get hurt.
3. Faulty Motor Mounts
Faulty motor mounts can lead to increased vibrations, impacting both the performance and longevity of your heating system. Let’s explore how this issue manifests in electric, natural gas, and propane furnaces and how to address it.
- Misalignment due to wear or tear can occur in the motor mounts of furnaces. Over-tightening or loosening of motor mount bolts may also contribute to this issue.
- The result is increased noise and shaking when the furnace turns on. It can also cause strain on your furnace’s motor, meaning you may need to replace your furnace sooner.
- To ensure this isn’t the reason for the shaking when the furnace turns on, regularly inspect motor mounts for signs of wear and misalignment. If you aren’t sure what to look for, consider professional maintenance.
4. Imbalanced Fan Blades
Imbalanced fan blades contribute to uneven vibrations, creating a disturbance in your living space. This section explores how balancing techniques, and professional maintenance, can help ensure balanced fan blades and help with reducing furnace vibrations.
- The fan blades in furnaces may become imbalanced due to the accumulation of dust, dirt, or debris. Wear and tear leading to uneven weight distribution can also contribute to this issue.
- As a result, furnace noise and shaking may occur during the operation of the furnace.
- Make sure you regularly clean the fan blades to prevent debris buildup. Balancing the blades with professional maintenance will help ensure even weight distribution, and stop furnace noise when your furnace turns on.
5. Worn Out Bearings in the Blower Motor
Worn-out bearings in the blower motor can most certainly lead to your floor vibrating when the furnace turns on. This section explores the impact of worn-out bearings on furnaces along with guidance on inspection and replacement. This common issue, leading to furnace noise and shaking, is best met with professional maintenance – or furnace replacement.
- The lack of lubrication due to a sealed motor design can lead to worn-out bearings in electric furnaces. Prolonged use without periodic professional maintenance may contribute to this issue.
- This leads to excessive furnace noise and shaking during the operation of the furnace, causing potential strain on the furnace’s motor.
- Ensure regular lubrication of the motor to prevent bearing wear. Schedule routine maintenance with a professional to inspect and replace bearings as needed.
6. When to Call a Professional?
While DIY troubleshooting is admirable, recognizing when to seek professional help is crucial. Attempting to rectify furnace noise and shaking on your own without an in-depth understanding of how your furnace works can lead to causing damage to your furnace or ductwork, and even lead to you getting hurt.
Here are the signs that you should seek professional maintenance:
- Of course, if floor vibrations persist despite your DIY efforts.
- Any suspicion of a more complex issue beyond basic troubleshooting. For instance, if you don’t see any buildup on your blower fan, or your ductwork seems to be secured in place. Before you start tinkering, call a professional.
