Why Does My Furnace Have Rust

3 Causes of Rusting in Your Furnace

It is essential to understand the importance of preventing rust in your furnace. Sometimes, people don’t think about it until they start noticing brown or yellowish stains on their home’s furnace. Rust can build up over time and cause problems like clogs, corrosion, and eventual equipment failure. Thankfully, there are ways you can take care of this problem before it becomes too severe. The following are the main causes of rusting in your furnace.

1. Leaking Air Conditioner

Air conditioner leaks will typically cause rust in your HVAC system. If you notice that there’s water dripping from the unit itself or around any pipes, this could be how it all starts. It will ultimately lead to rust buildup and other issues with your furnace if left unattended long enough.

The easiest way to prevent problems with your AC leaking is to make sure everything is properly maintained regularly. Also, consider checking for signs of damage to insulation over time due to naturally occurring wear and tear, which can cause further complications down the road without proper maintenance.

2. High Humidity

In addition to how you operate your furnace, humidity levels in the air can also affect how quickly rust will form inside. It’s crucial that you maintain a comfortable indoor temperature at all times and not let it get too hot or cold where moisture could start building up due to high humidity levels. Be sure to check for this before any problems become severe because lack of insulation can cause issues with keeping proper temperatures, which ultimately affects how much condensation builds up over time.

3. Furnace Exhaust Issues

If you have a furnace that’s working as it should be, then the only time rust would become an issue is if there were problems with how your unit was being vented. If this isn’t done properly over time, cracks can form in metal ductwork and allow moisture to seep inside, which eventually causes corrosion or other forms of damage.

Preventing any issues here will require regular inspections from a professional HVAC technician who can not only ensure everything is going smoothly but also identify potential problems before they cause more serious consequences down the road.
