AC Leaking Water

AC Leaking Water

One of the most common AC problems homeowners experience is an AC leaking water.

An AC system leaking water can be a much more serious problem than just a puddle of water on the floor. These leaks can cause major water damage, and in some cases, they are an indication that something is wrong with your air conditioner.

During the dehumidifying process, your air conditioner creates condensation, but under no circumstances should this water be leaking out of your vents.

While water leaks are generally small and easy to fix, left unattended they can damage your home’s wall, floors, or electrical systems and even lead to dangerous mold. These leaks can often be avoided by regular preventive maintenance.

Because it can lead to extensive damage, it is important to pay attention when your air conditioner is leaking water, but first you need to understand what’s causing the problem.

9 Reasons Your AC Is Leaking Water

If you see water coming out of your AC system, check a few of these most frequent causes for water leaks.

1. Clogged AC Drain Line

Most often, the reason your air conditioner is leaking is that the drain line is clogged. When the drain line is clogged, it causes the air conditioner’s drain pan to overflow, which causes the condensation produced by the air conditioner to leak out of the machine. Drain lines often become clogged with algae, dirt, and other debris, so it’s important to clean your AC drain line frequently to avoid leaks.

2. Broken Condensate Pump

The condensate pump is used to remove the condensation created by your AC system. If the pump is not working, it could be a problem with either the power to the pump, the motor or the pump itself. Consult an HVAC professional to determine the source of your pump’s issues.

A broken or dirty condensate pump can also cause your air conditioning unit to leak. Since an air conditioning unit continually produces condensation, this can cause the pump to become clogged with mold or mildew, so it is important to make sure that you clean it often to avoid these issues.

3. Disconnected AC Drain Line

Sometimes, air conditioning systems are not installed properly. If the drain pipe is not connected correctly, it may start to loosen over time. If the drain line disconnects from the unit, the condensation it produces will just leak onto the floor.

4. Clogged Air Filter

When is the last time you changed your AC’s air filter? Air filters are by far the most neglected part of an AC system even though they’re an essential component. If your air filter is dirty, it could be causing your AC system to leak water. A good rule of thumb is to change your air filter each month to keep your air conditioning system in top shape.

5. Damaged Drain Pan

While a leaking AC due to a cracked drain pan can be easy to fix, a cracked drain pan is not normal. The best plan of action is preventive action. Regular maintenance prevents many of the issues causing water to leak out of your AC.  Don’t wait until it’s too late, call an HVAC company today and find out how a technician can help you.

6. Refrigerant Leak

Refrigerant is used to cool the air that is pumped through your home, so when refrigerant levels get low from a refrigerant leak or other issue, your system will not operate as it normally would. If you notice that your system is starting and stopping frequently, this could be sign of a leak. If you suspect this is the case, contact an HVAC professional immediately. Refrigerant leaks can be dangerous and require a certified technician to fix the issue.

7. Improper Air Filter or HVAC Installation

When you replace your air filter each month be sure it is installed properly into your system. If the filter isn’t properly installed then it could lead to a malfunction in the system, causing leaks and other issues. The same tenet goes for the entire HVAC system. If the system is improperly installed then it can cause issues like excessive water leaks and inconsistent cooling.

8. Air Duct Leaks

Ductwork is important to your HVAC system. Your air ducts must be maintained just like the rest of your home. If air is leaking from your ducts then warm and cold air mix and produce water, or condensation.

9. Lack of Preventive AC Maintenance

An AC tune-up and preventive maintenance check will prevent clogged drains and related water leaks. Cleaning of your drain pan and lines will enable you to make it through the summer without having to worry about flooded areas in your home. Additionally, coil cleaning and refrigerant service can improve the efficiency of your system. Worn parts can be identified before they lead to problems, allowing you to know that your equipment is ready for the hot summer.
