A leaking furnace in the winter can be a frustrating problem for homeowners. Not only can it cause damage to your property, but it can also reduce the efficiency of your heating system. If you’ve noticed water around your furnace, it’s essential to take action promptly to prevent further damage. Here’s what to do if your furnace is leaking water in the winter.

  1. Turn off the furnace: Shut off the furnace and turn off the power source to prevent any electrical hazards.
  2. Check the condensate drain: The most common cause of a furnace leak is a clogged condensate drain. Check the drain and remove any blockages if possible. You can also try flushing the drain line with a mixture of hot water and vinegar.
  3. Replace the air filter: A dirty air filter can cause the furnace to overheat, which can lead to water leakage. Replace the filter if it’s dirty.
  4. Check for leaks in the humidifier: If your furnace has a built-in humidifier, it may be the source of the leak. Check the humidifier and replace any damaged or broken parts.
  5. Call a professional: If the above steps don’t solve the problem, it’s best to call a licensed technician to inspect and repair the furnace. Leaking water can cause significant damage to your furnace and home, so it’s important to address the issue promptly.
