The Importance of Proper Maintenance for Your Furnace

As an HVAC expert, I have seen countless furnaces stop working due to a variety of reasons. However, there is one common culprit that seems to be the root cause in most cases - a lack of proper maintenance. In this article, I will discuss the most common reason why furnaces stop working and provide tips on how to prevent it from happening.

The Importance of Air Flow

One of the most crucial elements in keeping your furnace running smoothly is ensuring proper air flow.


, debris, furniture, carpets, and other objects can easily block the flow of air that enters and passes through the oven, causing it to overheat.

This can lead to a breakdown or even worse, a potential fire hazard. To prevent this from happening, it is essential to regularly check and replace your air filter if it is dirty. This is a simple but essential part of oven maintenance that can go a long way in preventing breakdowns.

Clearing the Area Around Your Furnace

In addition to checking and replacing your air filter, it is also crucial to keep the area around your furnace clear. Make sure to dispose of any items stored around the boiler and keep at least 6 feet of free space. This will allow for proper air circulation and prevent any potential hazards.

Open Vents for Proper Air Circulation

Another important factor in maintaining proper air flow is ensuring that all vents in your home are open and unlocked.

If these vents are closed or blocked, it can restrict the flow of air and cause your furnace to overheat. Make sure to regularly check and clear any obstructions from your vents.

Strange Odors Coming from Your Furnace

If you notice any strange odors coming from your furnace, it is essential to address the issue immediately. If it smells like something is burning or like gasoline, it is crucial to call a technician right away. In the case of a gas leak, it is best to get out of the house and call 911. For other strange odors, such as the smell of rotten eggs, it is also important to call a technician.

Gas companies add a chemical to propane to create the characteristic sulfur scent of rotten eggs. If you smell this, there may be a gas leak, and it is best to stay out of your house until a professional can come and assess the situation.

Regular Maintenance for Optimal Performance

To prevent any potential hazards or breakdowns, it is crucial to stay proactive in routine heating, ventilation, and air conditioning maintenance. This includes regularly checking and replacing your air filter, clearing the area around your furnace, and ensuring proper air circulation through open vents. It is not recommended for homeowners to attempt any repairs on their furnace or its interior. This can be very dangerous if you are not professionally trained to work with air conditioning equipment.

Instead, it is best to call a technician for any repairs or maintenance needs.

The Importance of Annual Furnace Service Appointments

One way to ensure that your furnace is running smoothly and efficiently is by scheduling annual service appointments with a professional HVAC technician. During these appointments, they will check all components of your furnace, including the air filter and air flow, to ensure that everything is in proper working order.

The Role of the Flame Sensor

One crucial component that technicians check during these appointments is the flame sensor. This sensor is responsible for detecting whether or not there is a flame present in the furnace. If it is not functioning correctly, it can lead to a breakdown or even a potential fire hazard. If you have a modern furnace without a traditional pilot light, your oven is likely turned on using an electronic ignition system.

In this case, it is best to consult an accredited HVAC service provider for information on service options for your specific system.

When to Call a Professional

If you have followed all of these tips and still experience issues with your furnace, it may be time to call a professional. Furnace repair professionals have the knowledge and expertise to identify and resolve any problems with your furnace. It is always better to be safe than sorry when it comes to the safety and functionality of your furnace. In conclusion, the most common reason why furnaces stop working is due to a lack of proper maintenance. By regularly checking and replacing your air filter, clearing the area around your furnace, and ensuring proper air circulation, you can prevent potential hazards and breakdowns.

And remember, when in doubt, always call a professional for any repairs or maintenance needs.
