An air conditioner (AC) keeps your house cool and comfortable by extracting heat and humidity from the air. As the AC extracts humidity from the air, it produces condensate, or water, in your furnace or air handler. This water is typically collected in a drain pan and transported through piping into your home’s drain system.
As a side effect, faulty components or sludge buildup can cause the piping to become clogged. When this happens, water backs up in the drain pan in your furnace or air handler. It can then reach your home. This is particularly troublesome if your furnace or air handler is located in the attic or above a finished ceiling.
In a majority of homes, local codes necessitate a secondary or safety drain pan that is put underneath the furnace or air handler. This secondary drain pan has piping that is routed to the outside of the home. Usually, the outlet of the pipe is found above the outside of a window so it’s quickly noticeable if water begins draining from this pipe outlet. It is not normal for this to occur. If you see water dripping from piping on the outside of your home, this is often evidence the primary drain is backed up and water is now draining from the safety drain pan.
Here are the most common explanations for why your AC is leaking water and how to repair the issue. Some homes can also use a safety device that can automatically turn off your AC in the event the drain becomes clogged. In this case your system will stop cooling except if the drain is cleared of any obstructions. Regardless, if you spot water leaking, ensure you set your thermostat to “off” to stop anymore water damage and reach out to a Service Experts Heating, Air Conditioning & Plumbing service provider to correct the issues.

When hot, humid air runs along the evaporator coil, water collects on the chilled metal surface. At the end of the process, the water drains into a pan underneath the indoor coil within the furnace or air handler. As the cooling sequence takes place, the condensate flows out of the pan and into drain piping before the pan fills up.
However, mold, mineral deposits, dirt and other debris might clog the drain. This prevents the water from flowing away properly. Leave the unclogging process to an Expert like Service Experts Heating, Air Conditioning & Plumbing for the peace of mind it’s done properly and without causing more damage. Service Experts can also put in a safety device that will autonomously shut off your AC just in case the drain becomes blocked again in the future, thus preventing water damage inside your home. Of course, consistent maintenance on your AC will help keep your condensate drain flushed and unhampered.
While unusual, the drain line connection to the drain pan can become loose or disconnected. This may happen if someone is working nearby the unit or when swapping out the air filter. AC leaks may occur when the drain line is lose from the pan. Inspect your AC to see if the drain line is still leading to the coil drain pan. If it is no longer connected, we recommend calling an HVAC technician to repair this issue as soon as possible.

Some air conditioners require a condensate pump to properly drain the water. These pumps are required when the home’s drain system is found above the AC unit. Even if the drain is unobstructed, water can back up in the pan and leak out if the condensate pump is broken. First, determine that the pump is currently powered. If that’s not the problem, the AC leak may be due to a broken condensate pump. You should check with an air conditioning contractor like Service Experts Heating, Air Conditioning & Plumbing to resolve the issue.
If you see tiny drips in lieu of a larger puddle around the outside of your furnace or air handler, water may be dripping off the evaporator coil compared to properly moving into the drain pan and condensate line. This can occur if the coils are dirty, or if holes in the insulation easiest approach to keep the evaporator coil from going downhill is to keep up with annual air conditioning maintenance using a Service Experts Heating, Air Conditioning & Plumbing membership.
If you find a leak and the AC isn’t cooling like it’s supposed to, the refrigerant level may be low thanks to a leak. Air conditioners use refrigerant to produce cold air, so getting it inspected thoroughly during seasonal maintenance is extremely beneficial for the working condition of your unit. Without a full supply of refrigerant, the evaporator coils may freeze over and cause the drain pan to overflow as they thaw. Despite some expectations, your AC does not need to be recharged unless there is a leak. The system is sealed and recharging is only necessary when a leak appears in the system. Call Service Experts Heating, Air Conditioning & Plumbing as soon as you can to repair AC refrigerant issues quickly.
Your air conditioner’s filter needs to be changed regularly to produce adequate airflow. Without adequate ventilation, the evaporator coils could become too cold and freeze. The evaporator coils will then thaw, causing excess water to accumulate in the drain pan—sometimes producing an overflow. To resolve this, try changing your air filter. If the problem sticks around, more repairs may be required. Luckily, HVAC technicians from Service Experts Heating, Air Conditioning & Plumbing are happy to serve you, ensuring the problem gets solved.
Air conditioners are designed to be used during warm weather. Starting your AC when outdoor temperatures are 60 degrees Fahrenheit or below may cause the evaporator coils to freeze. Once thawed, the water and ice will drop off the evaporator coils and possibly result in an overflow thanks to ice blocking the drain pan opening. If a water leak persists, schedule a Service Experts Heating, Air Conditioning & Plumbing technician backed by our 100% service guarantee* to help solve the problem.
Air conditioners are manufactured to last, but nothing survives forever. If you possess an AC that is 12 years or older, the drip pan could be damaged or corroded after years of normal use. If the drain pan has holes in it, a water leak may appear as condensate seeps directly through it. Service Experts Heating, Air Conditioning & Plumbing can replace the drain pan and ensure your AC gets back to working normally.
