A leaking furnace is never something that you want to deal with, especially on the coldest winter night. There are numerous different reasons as to why you might be seeing water under your furnace, but the most common is a condensation leak. One important aspect of furnace leaks to remember is that they are a fairly common issue, but they need to be handled quickly to reduce the amount of damage that might be done to your home.
When you see water under your furnace the best thing to do is call your local HVAC contractor for an accurate diagnosis. However, it is important to stay educated about the different components that make up your furnace and where the issue might be.
Condensation leaks normally occur in high-efficiency furnaces, which have an AFUE rating of 90 or above. These types of furnaces have two heat exchangers which help to produce more heat.
With the production of more heat, there is more condensation which needs to be carried out of the home via a network of pipes. When this network becomes clogged or breaks the condensation gathers around the base of the furnace, leading to a collection and possible water damage.
The humidifier is another important part of your furnace. This device connects your plumbing system to the furnace which adds moisture to the air circulating throughout your home. When the connection is clogged, damaged or broken water will start to collect at the base of your furnace.
The furnace filter is used to filter out the dirt that is in the air and therefore needs to be replaced roughly every 90 days. When not replaced frequently enough it can cause the filter to get dirty and clogged which restricts the airflow into your furnace coils. This can cause the coils to freeze and forcing water to leak into the furnace causing more damage.
Each furnace has a network of plumbing throughout the unit, along with the systems centering and exiting the unit. When these systems get clogged it can cause a backup in the whole system leading to pipes breaking and leaking.
To conclude, there are many different reasons as to why your furnace is leaking water; some major, others minor. Calling your local technician is the first line of defensive against causing more damage to your home. By conducting annual service to your unit, you will be able to catch any problems before they become major. Finally, knowing the signs of needed repairs and listening to your furnace will make a major difference in the long run.
