By removing warmth and regulating the amount of humidity in the air, air conditioning systems are designed to keep your house comfortable. As your air conditioning system runs, it draws excess moisture out of the air, creating condensate. Basically, condensate is just condensed water that drains off of the cold areas of the system coils. This water is normally drained through piping into your house’s drain system or into your backyard.

However, another issue or a sludge buildup can block this vital piping, causing water to back up in the drain pan. From there, it can then overflow into your residence.

If you are noticing a water leak from your air conditioner or your heat pump, here are the most likely reasons why that is happening:

  1. The Condensate Drain is Full

As warm air passes over the evaporator coil, water droplets form on the chilly metal exterior. This condensate liquid makes its way into the condensate pan and then goes down the condensate drain line.

Sometimes, grease, mold, fungus, mineral deposits, dirt, or other accumulations can build up on the condensate pan and block this drain line. This obstructs proper drainage. To have your system properly cleaned out, you will need the help of our best specialists at Scottsdale HVAC Repair Pros to ensure that the work is done correctly and that all damage has been found and fixed.

  1. The Condensate Pump is Broken

Many air conditioners require a small condensate pump to ensure proper removal of accumulated water. Even if the drain is working correctly, a broken pump can cause water to build up and leak out of the condensate pan. Ensure the pump is receiving power, but if that is not an issue, it’s time to get the help of our best experts.

  1. The Evaporator Coil is Dirty or Damaged

Sometimes, we discover slow leaks and little drips instead of substantial puddle of water by your air conditioner. When this happens, the typical cause is that water is bouncing off the evaporator coil instead of traveling down the condensate line. This is a less common problem, but it happens when the coils are dirty or when insulation around the coils comes out of position and diverts condensate elsewhere. These issues are best prevented by annual air conditioning maintenance.

  1. The Evaporator Coil is Frozen

Sometimes, a film of frost grows on the indoor coils and drips onto the floor when the system is off and it begins to melt. If you see this, turn off your air conditioning system immediately because there is only one explanation—your evaporator coil is frozen.

To troubleshoot the cause of a frozen evaporator coil, check your filter to see if it is dirty. If it is dirty, then replace your filter and leave your system off for a couple hours to allow the frozen coil to thaw out. If your filter is fine or if the problem continues, then your refrigerant is likely leaking elsewhere in your system or something else is going wrong. In that case, you will need an expert HVAC technician like one from Scottsdale HVAC Repair Pros to check the refrigerant charge and plug any leaks.
