The furnace exhaust cap is a part that comes in handy for those who own a furnace. While it may not be a very important component for some people, the furnace exhaust cap is one of those things that you will definitely want to take the time to look into if you want to ensure that you are keeping your furnace in tip-top condition. While it may seem like an easy task to clean the exhaust cap out with a cotton swab, you will be surprised at the amount of dirt that is actually trapped inside of this small piece of equipment.
The furnace exhaust cap is designed to catch the excess moisture that is released by the furnace when it is burning. The moisture collects inside of the cap and can cause the cap to become cracked over time. While the exhaust cap is designed to keep the moisture inside of the furnace, it is not immune to being cracked. If you do happen to have one of these caps cracked, you will have to take the time to clean it out, as this will prevent the cap from cracking further down the road.
