Troubleshooting My Furnace

As soon as winter rolled around this year, I knew that I had a problem. Our home heating system didn't seem to be working well, and it was really frustrating. We would wake up to absolutely frosty mornings in our own home, and so I decided to pull out the user's manual. I started researching different furnace problems and it occurred to me that the issue might be the filters. I checked them, and you wouldn't believe how full of dust and debris they were. After they were replaced and the air handler was blown out, my furnace started working again. Check out this blog for more information about troubleshooting your furnace.

Why Is There Water At The Base Of Your Air Handler?

Water at the base of your air conditioner's air handler means there is something wrong with your system. The AC does produce some condensation, but there is a mechanism for getting rid of the water so that it doesn't drip onto the floor. Here are some of the common reasons an AC may drip water.

The Drain System Is Clogged

The condensation manufactured by the AC needs a clear channel to drain away, which will not be the case if the drain tube or pump is blocked. A common cause of clogging here is algae growth, which isn't so surprising given that algae thrive in wet places and the drain system is perpetually wet. It may also be clogged by ice if the system is freezing and the water can't flow out.

The Condensate Pump Isn't Getting Power

Some AC systems are designed with electric condensate pumps to get the water flowing out of the unit into the drain pan. This means an electrical malfunction that prevents the condensate pump from working may also cause water to collect at the base of the air handler. In some cases, the malfunction may not even be with the AC system, but rather with the electrical outlet that should be feeding the pump with power.

The Float Ball Is Stuck or Damaged

Most condensate pumps are equipped with a float ball that rises when the level of water rises; this turns on the pump to get rid of the collected water. Therefore, the pump won't start working if the float ball mechanism is stuck or if the float ball is damaged and can't rise. In such a case, the water will collect and eventually overflow onto the floor.

The Drain Pan Is Damaged

The drain pan is where the condensed water stays until it is drained off via proper channels. The pan is susceptible to damage just like other parts of the AC system. For example, it can develop holes or cracks due to corrosion. If that happens, then any little water that drops into the pan will seep right to the floor.

The Air Filter is Dirty

Running an AC with a clogged air filter has many consequences, one of which is water pooling at the base of the unit. This happens when the clogging reduces the amount of airflow over the coil and the coil freezes. Further problems occur when the ice collected on the ice melts and drips to the flow.
