Give Your Furnace the Attention it Needs

Furnaces are complex machines that require regular maintenance and care to ensure they continue to operate safely and efficiently. However, even with proper maintenance, good furnaces can go bad. In this article, we will explore why this happens and what steps you can take to keep your furnace in good working order.

One of the most common reasons that a furnace fails is due to a faulty heat exchanger. The heat exchanger is responsible for transferring heat from the burning fuel source to the air that circulates through your home. Over time, the heat exchanger can become cracked or corroded, which can allow dangerous gases, such as carbon monoxide, to leak into your home. This can be extremely dangerous, as carbon monoxide is odorless and can be deadly in high concentrations. If you suspect that your heat exchanger may be faulty, it is important to have it inspected by a qualified HVAC technician.

Another important component of your furnace is the blower, which is responsible for circulating air through your home. If the blower becomes clogged with dirt, dust, or other debris, it can impede the airflow through your home and cause your furnace to work harder than necessary. This can lead to increased wear and tear on the furnace, as well as reduced energy efficiency. To prevent these issues, it is important to regularly clean your furnace’s blower and replace the air filter as needed.

In addition to these specific issues, there are a number of other factors that can contribute to the failure of a good furnace. For example, if your furnace is oversized for your home, it may cycle on and off too frequently, which can cause unnecessary wear and tear on the unit. Similarly, if your furnace is too old, it may not be as energy efficient as newer models, which can result in higher utility bills and a shorter lifespan for the unit.

To ensure that your furnace is safe to operate, there are a few key things to look for. First, be sure to regularly inspect the furnace for any signs of damage or wear and tear, such as cracks in the heat exchanger or frayed electrical wires. Second, make sure that your carbon monoxide detector is working properly and that you have one installed in the room where your furnace is located. Finally, be sure to have your furnace inspected by a qualified HVAC technician on a regular basis. A professional inspection can identify potential issues before they become major problems, which can help extend the lifespan of your furnace and keep your home safe and comfortable.

There are a number of factors that can contribute to the failure of a good furnace, including issues with the heat exchanger and blower, as well as more general issues related to the age and efficiency of the unit. To ensure that your furnace is safe to operate, it is important to regularly inspect and maintain the unit, as well as have it professionally serviced on a regular basis. By taking these steps, you can help extend the lifespan of your furnace and ensure that your home remains comfortable and safe.
