A leaking AC unit can result in severe damage to walls, flooring, furniture and more. Here’s what you can do!
Water leaks inside the home are always a major cause of concern for homeowners. Where is the leak coming from? What are the causes of the water leak? What is the extent of damage occurring to other parts of the home including furniture, walls, etc.? What is the cost to repair the damage done?
These are the first questions that cloud the mind when a water leak is detected in the house. Moreover, if the leak is originating from the Air Conditioner, there is often more reason to be concerned. A water leak in an AC can result in severe damage to walls, flooring, furniture, electrical settings as well as the HVAC unit itself. Considering extensive leaks, one can surely get left with heavy damage repair bills.
Essential Steps to Take If the AC Is Leaking
If the source of the water leak is the air conditioner, then it is essential to follow the below steps before doing anything else.
- Turn off the AC. Water leaking from the AC can first and foremost damage the unit. Turning it off before starting any form of troubleshooting can prevent further damage.
- Clean up. Leaked water should be cleaned up immediately, as it can seep through walls and flooring and cause damage to furniture, décor, upholstery, ceilings, etc.
Finding the Cause of the Water Leak
Conducting a thorough check can help identify the cause. There are a few common issues that can cause a water leak inside the AC.
Issues With the Drain Line
Drain line issues are one of the most commonly found causes of water leaks. Air conditioners function by removing the water content naturally present in the air in the form of moisture. This moisture condenses on the evaporator coils and flows down through the drain lines. If debris and dirt accumulates inside the drain line, it can get clogged, or get ruptured due to excess collection of back-logged water.
Drain lines can also get disconnected and cause a leak. Our St. Louis HVAC technicians explain that this happens either due to vibration from the AC or can happen if installation of the drain line has not be done properly.
Issues With Pump and Pan
Often, with units that are placed inside the basement, the drain line carries the condensate water into a drain pan. This water is then pumped out with a drain pump. Wear and tear of the drain pan and pump are most common causes of water leaks.
An old, rusted and broken drain pan can leak due to holes and cracks, whereas, if the pump breaks down, the drain pan can overflow with collected water causing water leaks.
Issues With Evaporator Coils
Evaporator coils, at times, can develop a layer of ice or frost. If the AC runs continuously with ice or frost collection on the evaporator coils, it can cause heavy damage to the compressor. A damaged compressor often requires a complete unit replacement.
Ice or frost over the evaporator coils is caused when a clogged or dirty air filter reduces flow of air over the evaporator coils or due to a refrigerant leak.
