3 Reasons Your Furnace Is Leaking

Furnace Leak in Littleton, CO

It’s alarming to come home and discover a puddle of water under your furnace. This is a sure sign that something’s amiss with the furnace and will quickly lead to problems like mold and mildew growth if it’s not addressed right away. While this situation can be a headache for homeowners, Littleton Heating and Air Conditioning will help you troubleshoot the issue and make sure it’s fixed right away. During our 40+ years providing furnace services in Littleton, CO, we’ve seen—and fixed—many common issues.

Here are some of the most common causes of a leaky furnace:

1. Condensation Leak

Condensation leaks are by far the most common cause of furnace leaks. High-efficiency furnaces have a cool exhaust which produces condensation. If you have this kind of furnace, you’ll see a white PVC pipe leading to a drain in the ground. If the floor drain becomes blocked or clogged, it could result in condensation accumulating on the floor. Additionally, cracks in the PVC tubing can also cause water to leak out.

2. Faulty Heat Exchanger

The heat exchanger is also common with modern, high-efficiency furnaces. This component circulates heat that would otherwise be wasted; as a byproduct of this exchange, it creates liquid as gases cool down. Unfortunately, this problem is a major fix and often very pricey. Depending on how old your furnace is, it may be more practical to simply replace it with a more reliable unit.

3. Malfunctioning Furnace Humidifier

The process of creating heat can sap humidity from the air, which is why many HVAC systems also include a humidifier. The humidifier helps replace some of that moisture to prevent the air in your home from becoming uncomfortably dry. Humidifiers, like their name implies, generate a lot of moisture. If the humidifier is cracked, clogged, or blocked, it can result in water leaking out of the furnace and pooling on the floor nearby. The humidifier is one of the components our technicians check during yearly maintenance, so having a regular tune-up can usually prevent this problem.
