You may be surprised to find a pool of water next to your dry air furnace, but this is a common problem that many homeowners have during the wintertime. There are several reasons why water is collecting around your heater.

1. Water Condensation in High-Efficiency Furnaces

High-efficiency furnaces use different technology than older units to reduce energy use in your home. These units have an outlet to release cool air as part of the heat exchange process. If the airflow is obstructed, condensation builds up inside the furnace.

2. Filter Needs to Be Replaced

If you haven’t replaced the filter in your heater for some time, it may be clogged. Condensation will form on the coil and may freeze. If there is a lot of condensation, it can leak down to the floor around the unit.

3. Leaks From the Air Conditioning Unit

If your heater is in the same area as your air conditioner, the water may be coming from a leak or clogged drain inside the A/C unit. This typically happens when the air conditioner is running at the same time as your furnace, which may indicate that there is also a problem with the power controls for the air conditioner.

4. Damage to the Heat Exchanger

The heat exchanger inside your furnace uses fluids and other technologies to transfer heat. The process of heat exchange can create water vapor that may overwhelm the system and collect at the base of your furnace unit.

5. Damage to the Humidifier

If you have a humidifier connected to your HVAC system, the water around your furnace could be coming from that piece of equipment. The most common reasons behind water leaking from a humidifier are:

  • Clogged tubes or drains
  • High humidity settings on the unit
  • Water flow that is too high for the unit
