Read this blog to know what causes your furnace to leak water.

Condensate Drain Problems

Condensation is part of the process of a furnace’s function. That’s why there are specific parts that eliminate excess condensation. The furnace’s condensate drain gathers the condensation and removes it through the drain line, emptying it outside.

Once the drain gets clogged, the condensation will gather in the condensate pan and overflow. It is the reason why your furnace leaks water.

Clogged Air Filter or Evaporator Coils

A split HVAC system, which includes an A/C and furnace acting as an air handler, can cause problems. The air filters in your furnace pull the debris out of the air, then it passes it over to the evaporator coils to be heated. If these air filters get too dirty or clogged, they can’t filter the air efficiently.

The condensation that passes over the coils to the condensate gets stuck in the process. Then it accumulates, causing the furnace to leak. It’s also the same with the air filters. If both components are left dirty, it could sometimes cause something worse, like permanent damage. 

A Faulty Secondary Heat Exchanger

A furnace works by passing heat from burned fuel into your home. The heating system gives the air to the heated energy, making for heat exchange and warming your home. Some common issues with the heat exchanger are:

  • Cracked heat exchanger
  • Pitted, rotted, or rusted heat exchanger
  • Heat exchanger with holes

If you notice any of these issues are causing furnace leaking or other problems, you may need a complete replacement. Contact an HVAC expert to handle the job.

A Leaking Furnace Humidifier
