Is Moisture a Problem for Your Furnace?

Inevitably, there will be some humidity in the air around your home. That means there will also be humidity inside of your furnace. Although your furnace has a condensate drain line that helps to capture some of the excess moisture and drain it outside of your home, there is still such a thing as too much humidity.

You can keep reading to learn more about the signs that moisturizer problem inside of your furnace and what you can do about it. 

Why Moisture Inside Your Furnace is Bad

Some moisture in the air during the winter season is a good thing. Balanced humidity levels help make the air feel warmer and more comfortable. But if there’s too much moisture, it can cause a lot of problems for your furnace and the rest of your home. 

Moisture helps to feed mold growth. Since the inside of your furnace is dark, adding moisture into the equation creates the perfect atmosphere for mold to thrive. Aside from mold growth, moisture can also interfere with how your furnace operates to heat your home and add strain to the system. You may see upticks in energy costs and changes in how effectively your furnace is able to heat your home – or not.

Signs of Moisture Buildup in a Furnace

One of the obvious signs that you have too much moisture in your furnace is noticing a leak. Your furnace does have condensate drain lines that help to collect excess moisture and drain it outside of your home. But if this condensate drain line gets clogged or damaged, moisture can build up in the lines and spill out into your furnace and your home.

Even without a leak, you may notice a musty or moldy odor coming from the air vents. Your furnace should never produce any bad smells, so noticing an odor is a major red flag that something is going wrong inside of the system. In the case of a musty odor, moisture buildup is usually the culprit. Noticing an odor can mean that mold has already begun to develop inside of the system and needs to be irradicated. 

When you open your furnace to take a look at the entire cabinet and make sure everything is operating the way it should, you may notice rust when there is moisture buildup. Unfortunately, moisture can cause metal inside of your furnace to corrode.

Rust cannot be reversed once it begins, so the rusted components may need to be completely replaced to prevent additional damage. However, if you get the moisture buildup under control and manage it in the future, you may be able to prevent additional damage from happening.
