6 Causes Of Rust In A Furnace

If you are dealing with any rust or corrosion on your furnace, it can affect the efficiency of your unit. If you remove rust, you might notice a difference in the efficiency of your furnace. Several things might cause corrosion, but the most common is a leak in the system. This blog will explain why you have rust on your furnace, what it can do to the system, why you should have it removed, and how you can remove it.

1. Leaking Air Conditioner

   One of the most common reasons you might have rust on your furnace is a leaking air conditioner. If you notice rust on your furnace and do not have an air conditioning unit, this might be the source of the problem.

   There is a high concentration of moisture inside your home, which causes corrosion to form on items with metal parts. If the air conditioner were to leak, it would allow even more moisture into the home, which would result in even more corrosion. Another source of corrosion is from a water damage event, which could cause this problem. If you notice rust on your furnace and your AC unit is not leaking, there is a more probable source.

2. Leaking Water Heater

   If you have rust on your furnace from a leaking water heater, it can be from many different problems. The most common reason for this type of leak is due to a faulty tank. If the tank is not installed correctly, it could leak from around the seams. Another issue that can cause a leak from a water heater is corrosion, which forms over time. Several issues can cause corrosion, but having excess minerals in the water supply causes most problems. If you need your furnace inspected because it is rusting, a Grove, IL, professional from Fire ‘n’ Ice Heating & Cooling, Inc. would be able to determine if the rust is from a leaking water heater.

3. Improper Installation

   If you have a furnace that has been installed improperly, you might experience problems with it in the future. An improper installation can cause problems with the efficiency of your furnace and even cause damage to other parts of your home. If your furnace is not working properly, it can affect the temperature of your home. If it is too cold, then you will need to use more heat which costs more money. If your furnace is not working properly, it could cause damage to other parts of your home as well. For example, it could cause mold to grow in your walls. You can avoid this type of problem if the furnace is installed correctly.

4. Combustion Gas Reaction

   Another term for a combustion gas reaction is a “blocked flue.” This situation takes place when the combustion gas from the furnace reacts simultaneously with water vapor. In this reaction, corrosion can form on metal parts of the furnace, which results in rust. An example of a product that can cause this reaction is a high-efficiency water heater. If you have this issue, then your furnace will need to be replaced.

5. Improper Repair

   Sometimes the cause of the rust on your furnace can be caused by a previous faulty repair of your furnace that you did at a high temperature or pressure and that resulted in water getting into the system. If you notice rust on your furnace and do not think there was a recent mistake, you might want to have it inspected by a specialist.

6. Furnace Exhaust

   If you notice rust on your furnace, your furnace is working, and there is no damage to it, then it is possible that a faulty exhaust system caused the rust. This occurs when gases that leave the furnace do not go up and out of your home. Instead, these gases go behind the furnace and mix with excessive moisture. This moisture sometimes comes from a leak in the water heater. The mixture of gas and moisture forms rust or corrosion on many items in your home. Even though you might not notice rust on your furnace, this could still be the cause of the problem. If you want to prevent this from happening, you should have your exhaust system checked periodically by a professional.

While a failed air conditioner, leaky water heater, or improper installation can cause your furnace to rust, there are several other possible reasons why you might have rust on your furnace. If you suspect that your furnace is rusting and if the problems that caused it to happen are still ongoing, then you should contact Fire ‘n’ Ice Heating & Cooling, Inc. in Grove, IL, for AC repair, furnace repair, furnace maintenance, and furnace installation.
