Why Is My Air Conditioner Leaking?

Is your air conditioner leaking water? Picture it: You come home wanting to relax after a long day, only to find your floor is wet because your air conditioner has been leaking water for some reason! Immediately, your mind starts racing about AC repair costs and the frustration of being hot, uncomfortable, and possibly out a few hundred bucks.

Just calm down and take a breath. We are here to tell you that it may not be quite as bad as it seems. Several things can cause an AC unit to leak water, some of which do not require significant AC repairs and may have simple solutions.

Let’s examine the most common reasons your air conditioner might be leaking, what to look for, how to prevent further damage, and when it’s time to call in the pros for expert AC Leak Repair –

Common Causes of Air Conditioning Leaks

All AC units contain an evaporator coil within the indoor unit, which cools the warm air blowing over it and creates condensation. As the moisture builds up, it drips down into the drain pan and then down a condensation drain line. Now that you have an idea of where the moisture is most likely coming from, let’s talk about a few things that could cause leaks:

• Cracked or Missing Drain Pan: First and foremost, you may need a new drain pan. Drain pans collect all of the moisture produced within your unit, and if they can’t hold water or are missing altogether, there will be a leak.
• Improper Installation or Maintenance: Incorrect installation or lack of proper AC maintenance can also lead to AC leaks. Poorly installed drain pans, loose fittings, or damaged components can all contribute to water leakage. Ensure your AC unit is installed correctly by hiring a qualified AC installation team and schedule regular maintenance to catch any potential issues before they escalate. Routine inspections and tune-ups can significantly reduce the risk of leaks and keep your AC system running efficiently.
• Clogged Air Filters: A dirty or clogged air filter restricts airflow, causing the evaporator coil to freeze and eventually thaw, leading to water leakage. Regularly inspect and replace your air filter every one to three months, depending on usage and the manufacturer’s recommendations. A clean air filter not only helps prevent leaks but also improves indoor air quality and prolongs the lifespan of your AC system.
• Frozen Evaporator Coil: If your air conditioner’s evaporator coil freezes, it can cause water to overflow and leak onto your floor. Several factors can contribute to a frozen evaporator coil, including low refrigerant levels, restricted airflow, or a malfunctioning blower motor. Check for signs of ice buildup on the evaporator coil, and if present, turn off your AC system to allow the ice to thaw completely before restarting it. Address any underlying issues promptly to prevent future coil freezing and leaks.
• A Broken Condensate Pump: In AC systems, especially those in basements or crawl spaces, a condensate pump is used to remove water from the unit. If the condensate pump fails or becomes overwhelmed, it can result in water backing up and leaking from the AC unit. Check the condensate pump for signs of damage or malfunction, such as strange noises or failure to operate. If the pump is the problem, it will need to be repaired or replaced by a professional technician.
• A Clogged Drain Line:  One of the most common culprits behind AC leaks is a clogged drain line. Over time, dirt, dust, and algae can accumulate in the drain line, obstructing the flow of water. When the line becomes blocked, water backs up into the unit and eventually starts leaking. To check for a clogged drain line, locate the drain line near your outdoor condenser unit and gently pour a mixture of bleach and water down the line to clear any blockages.
• Low Refrigerant: Low refrigerant can also cause your evaporator coils to freeze and then melt, resulting in excess moisture production and leaking. If your air conditioner isn’t cooling or is making a hissing/bubbling sound (the sound of leaking refrigerant), you may need to have an HVAC technician service your unit. This will most likely involve either repairing the leak or replacing the whole unit.

Preventing Further Damage to Your AC Unit

While identifying the cause of your AC leak is crucial, taking steps to prevent further damage is equally important. If you notice water pooling around your air conditioner, immediately turn off the unit to prevent electrical hazards and potential water damage to your home. Clean up any standing water promptly, and if the leak persists, contact a reputable HVAC company like Madd Air Heating & Cooling for prompt assistance. Ignoring an AC leak can lead to costly air conditioner repairs and damage to your property, so it’s best to address the issue as soon as possible.

AC malfunctions can be a frustrating and potentially damaging problem, but it’s not one you have to tackle alone. By understanding the common causes of AC leaks, knowing what to check for, and taking preventative measures, you can minimize the risk of leaks and keep your AC system running smoothly.
