Why Rust Forms on Your Furnace

Furnace Rust in Asheville, NC

Your furnace accumulates rust for a wide range of reasons. If you allow the problem to persist, it will increase the extent of damage and increase the cost of your repair. Learning why your furnace rusts is necessary to prevent any further degradation.

What Causes Rusting?

Rust typically does not appear overnight but over time. This occurs when water or oxygen interacts with metal to create iron oxides. Your heater becomes discolored as the materials break down due to chemical reactions. Rust particles can block the vents and interfere with the normal functioning of your heater.

Constant exposure to rain and moisture is known to increase the speed of rusting. High levels of humidity increase the amount of water vapor in the room’s air. Humidity increases when the amount of heat increases in the room.

Poor ventilation can retain moisture within the heater and prevent the release of air. This is often caused by a mechanical failure or a lack of cleanings, such as a blocked air filter or vent.

How to Fix Rusting

Anyone can remove superficial rust using brushes and cleaning products. Cleaning your furnace is a tedious, time-consuming task that is often better handled by a professional. Another problem is that it’s often ignored and fixed only if it makes your heating less effective. Corrosive metal worsens the longer that you leave it alone. The damage often becomes so severe that a repair is not effective, and you need a total replacement.
