An air conditioner (AC) keeps your house cool and comfortable by removing heat and humidity from the air. As the AC extracts humidity from the air, it generates condensate, or water, in your furnace or air handler. This water is normally kept in a drain pan and routed through piping into your home’s drain system.
Unfortunately, faulty components or sludge buildup could cause the piping to become clogged. When this happens, water backs up in the drain pan within your furnace or air handler. It can then reach your home. This is namely troublesome if your furnace or air handler is up in the attic or above a finished ceiling.
In the bulk of homes, municipal 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. Most of the time, the outlet of the pipe is placed above the outside of a window so it’s easily noticeable if water starts draining from this pipe outlet. It is not normal for this to occur. If you see water draining from piping on the outside of your home, this is likely an indication the primary drain is blocked 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 could 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 until the drain is cleaned of any obstructions. Regardless, if you discover water leaking, make sure to set your thermostat to "off" to stop any further water damage and get in touch with a Strand Brothers Service Experts service provider to correct the issues.

1. Condensate Drain Is Blocked
When hot, humid air runs along the evaporator coil, water condenses on the cold metal surface. At the end of the process, the water drains into a pan under 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 stops the water from moving away correctly. Entrust the unclogging process to an Expert like Strand Brothers Service Experts to guarantee it’s performed properly and without causing additional damage. Service Experts can also put in a safety device that will autonomously turn off your AC if the drain becomes blocked again sometime after, thus preventing water damage in your home. Of course, routine maintenance on your AC will help keep your condensate drain clean and unhindered.
2. Drain Line Is Disconnected
While not very common, the drain line connection to the drain pan may become loose or disconnected. This will sometimes occur if someone is working around the unit or when swapping out the air filter. AC leaks might occur when the drain line disconnects from the pan. Check your AC to determine if the drain line is still fully connected to the coil drain pan. If it is no longer connected, we suggest calling an HVAC technician to take care of this issue as soon as possible. Schedule an appointment with Strand Brothers Service Experts today.
3. Condensate Pump Isn’t Working
Some air conditioners need a condensate pump to adequately drain the water. These pumps are compulsory when the home’s drain system is placed above the AC unit. Even if the drain is clear, water may build up in the pan and leak out if the condensate pump is damaged. First, determine that the pump is currently powered. If that’s not the problem, the AC leak might be due to a broken condensate pump. You should check with an air conditioning contractor like Strand Brothers Service Experts to resolve the issue.
4. Evaporator Coil Is Dirty or Damaged
If you see tiny drips instead of a larger puddle nearby the outside of your furnace or air handler, water could be splashing off the evaporator coil compared to properly flowing into the drain pan and condensate line. This can happen if the coils are dirty, or if holes in the insulation surrounding the coils redirect the water. The easiest approach to prevent the evaporator coil from going downhill is to keep up with annual air conditioning maintenance using a Strand Brothers Service Experts membership.
5. Low Refrigerant Level
If you find a leak and the AC isn't cooling well, the refrigerant level may be low because of a leak. Air conditioners count on refrigerant to create cold air, so getting it checked thoroughly during seasonal maintenance is extremely important 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 needed when a leak happens within the system. Call Strand Brothers Service Experts right away to resolve AC refrigerant issues quickly.
6. Dirty Air Filter
Your air conditioner's filter has to be changed regularly to encourage proper airflow. Without adequate ventilation, the evaporator coils can become too cold and freeze. The evaporator coils will then thaw, causing excess water to collect in the drain pan—sometimes producing an overflow. To resolve this, try changing your air filter. If the problem remains, more repairs will sometimes be required. Thankfully, HVAC technicians from Strand Brothers Service Experts are willing and able to serve you, ensuring the problem gets resolved.
7. Outdoor Temperature Is Too Cold to Run AC
Air conditioners are built to run during warm weather. Running your AC when outdoor temperatures are 60 degrees Fahrenheit or colder will sometimes cause the evaporator coils to freeze. Once thawed, the water and ice will drop off the evaporator coils and may lead to an overflow due to ice blocking the drain pan opening. If a water leak persists, schedule a Strand Brothers Service Experts technician backed by our 100% service guarantee* to help solve the problem.
8. Damaged Drip Pan
Air conditioners are manufactured to last, but nothing survives forever. If you own 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 could appear as condensate seeps directly through it. Strand Brothers Service Experts can replace the drain pan and ensure your AC gets back to working like it’s supposed to.
