Rust Could Be Destroying Your Furnace System Right Now

Rust, as it seems, never sleeps. It eats at metal and destroys it little by little. This is the same thing that happens in your home heating system. Rust forms in this appliance especially in areas with high humidity. Once you turn on the heating system, you inadvertently create a temperature imbalance within the system, which can lead to a higher level of moisture in the air. Over time, this humidity can contribute to damage even in the most reliable heating systems.

Of course, the lifespan of any heating system can be extended by simply not using it. However, this is not a practical or even possible option, especially for people who live in low-temperature areas. Eventually, damage and aging will happen to your heating system, regardless of what you do. Rust in furnace is quite common, which means it is likely that your heating system might already have it.

What Causes Furnace Rust?

According to professionals, there are three main reasons why rust develops in the heating system. These include:

High Humidity Or Water Leaks

High humidity is one of the most common causes of rust in heating systems. When humidity levels are high, it means that there is a lot of water vapor present in the air. Some regions have higher humidity levels compared to other regions, simply due to the environment. Since the house is a mostly enclosed structure, the conditions indoors can even worsen when more moisture is added to the air via water leaks.

Air Conditioner Leaks

A water leak is quite common in heating systems. This is usually caused by water coming from the air conditioning unit. Since air conditioners produce water via condensation, they also contribute to the development of rust in the heating system. Many types of air conditioners are so-called centralized systems. These systems are integrated into the ductwork – the same ductwork that the furnace is connected to. This allows leaks from the AC system to travel to the heating system. Not only do AC leaks increase humidity levels but they can also cause water to pool in areas close to the cooling and heating system. This not only contributes to the development of rust but also increases the risk of mold and mildew growth.

Furnace Exhaust Issues

Furnace exhaust is a by-product of using a heating and cooling system. Because the furnace has to create heat, it will also produce more water vapor that results in higher humidity within the enclosed structure. The furnace produces hot air which then cools down as it is pushed from the burner. The sudden change in temperature can lead to condensation within the unit.

What Problems are Associated With Rusty Furnaces?

All furnaces will rust eventually, even if it takes a long time. Rust will ultimately win. The good news is that you can still do things right now to slow down rust and make sure that your heating system lasts for many years. First, it is important to be observant about your furnace. By simply being watchful, you can implement the right steps to help prevent premature issues from happening.

Tips to Avoid Furnace Corrosion

Here are ways to help prevent the buildup of rust in your furnace.

Schedule Annual Furnace Maintenance

Regular furnace maintenance, which should be scheduled on a yearly basis, is one of the best ways to arrest rusting. It is a fairly affordable service that will help you save hundreds of dollars on repairs or a few thousand dollars on a furnace replacement. Your HVAC contractor will perform a thorough inspection to detect rust, thus ensuring that your furnace is safe and in top shape.

Clogged Furnace Burner Jets

Rust will also affect how your system performs. When your burner jets are clogged, the system will not be as efficient, which means it will have to use more fuel just to generate the required heat. Not only that, but an inefficient burner can also increase the levels of carbon monoxide, which is a highly toxic gas.

Furnace Fuel Supply Lines

Rust will eventually cause the failure of fuel supply lines. This can increase the likelihood of a fire or even an explosion – something that you do not want to experience in your lifetime. Fuel line explosions can be severely damaging and could place your life and those of your loved ones at risk.

Rust is far more than just an annoying inconvenience. It is an actual hazard that can cause serious damage to your home. It is not only unsightly but also a danger to your family and pets. Keep in mind that when you see rusty streaks on the exterior of an appliance, it is likely that the interior is already severely damaged.

Repair All Furnace Issues Immediately

Other than ensuring that your furnace receives an annual inspection, make sure that all furnace issues are fixed right away. Annual HVAC maintenance checks can identify problems with rust early, which means that the HVAC contractor can correct and fix any problems immediately. If there are degraded components or parts, these have to be fixed as well.

In some cases, however, some systems are so damaged that they can no longer be repaired. If they can be fixed at all, it is likely that you will spend a good amount of money on the job. An older furnace will no longer be as efficient as a newer system, which means it may be running at low efficiency. There is no way to determine this yourself, which is why it is important to seek professional advice.
