Encountering water leakage from your gas furnace can be unexpected and concerning. If you’ve noticed this, we’ve got you covered below. Read on as we take a deep dive into this issue.
Why Is My Furnace Leaking Water?

When you call for our “fix heater near Santa Clarita” service to help fix furnace leaks, the first initiative would be to help you understand why the problem is happening. Skipping the root of the problem may mean that you’ll likely have the issue recur.
So, why is my gas furnace leaking water? Read ahead.
Condensation Buildup
During the regular operation of a gas furnace, combustion generates heat and moisture. This moisture usually condenses and is channeled away through a condensate drain. However, if this drain becomes clogged or obstructed by debris, algae, or mold, it can lead to water accumulation around the furnace, causing furnace leaks.
Clogged Floor Drain
Some gas furnaces have a condensate drain that connects to a floor drain for the disposal of water. If the floor drain becomes clogged due to dirt, debris, or other blockages, it can impede the proper drainage of water from the furnace. This blockage can cause water to back up and leak around the stove.
Secondary Heat Exchanger Problems
The secondary heat exchanger is designed to manage excess moisture created during heating. If this component develops cracks or blockages, it can result in a leaking furnace(1).
Improper Installation or Seals
Poor installation or faulty seals in the furnace can also result in water leakage. If the seals around the furnace’s components are damaged or incorrectly installed, they can allow moisture to escape and accumulate around the unit.

High Humidity Levels
In some cases, excessively high humidity levels within the home can cause the furnace to produce more condensation than the drainage system can handle, resulting in water leakage.
Incorrectly Sized Exhaust Pipe
The exhaust pipe plays a critical role in safely venting combustion byproducts, such as carbon monoxide, outside your home. If the exhaust pipe is improperly sized, it can cause issues. A pipe that is too small can lead to restricted airflow, causing condensation to build up and leak back into the furnace. Conversely, an oversized pipe may not effectively expel gasses, leading to condensation and subsequent water leakage within the stove.
When offering our central heating installation Santa Clarita, we ensure everything is sized correctly to avoid such issues.
What Happens If Gas Furnace Water Leaking Is Ignored?

Your gas furnace and air conditioner will often continue to function for some time, even with water leaking. This scenario often tempts homeowners to ignore maintenance and repairs, continuing to use the systems.
You want to avoid this at all costs, as it will ultimately result in something more costly to repair. Here are some of the consequences that develop from leaking furnaces.
- Property Damage: Water leaks pose a significant risk to property. Accumulated moisture can damage drywall, wooden structures, flooring, and nearby fixtures. Over time, this damage may require extensive repairs, impacting the property’s structural integrity.
- Mold Growth: Moist conditions resulting from leaks create an ideal environment for mold growth. Mold damages surfaces and poses health risks, potentially causing respiratory issues and allergies for inhabitants.
- Corrosion: Continuous water exposure can result in the corrosion of metallic components within the furnace and its surroundings. Corrosion weakens these components, affecting the furnace’s performance and durability.
- Electrical Hazards: Water leaks near electrical components pose a severe risk of short circuits and electrical malfunctions, potentially leading to fires or other safety hazards.
- Operational Inefficiency: Persistent leaks can significantly impair the furnace’s functionality. The system may become less efficient, resulting in higher energy bills and potential breakdowns, which can necessitate costly repairs or replacements.
- Structural Deterioration: Prolonged exposure to water can weaken the structural integrity of the furnace housing and its surrounding areas, potentially leading to collapse or structural damage.
- Indoor Air Quality: Moisture can contribute to poor indoor air quality, promoting the growth of bacteria and allergens that can exacerbate health issues for occupants.
