Top Reasons Your AC is Leaking Water and Why You Should Call an AC Maintenance or AC Repair Contractor

When your air conditioner starts leaking water, it’s more than just an inconvenience—it’s a sign that something’s wrong with your system. Ignoring the issue can lead to water damage, mold growth, and costly repairs. Here are the top reasons your AC might be leaking water and why you should contact a professional AC maintenance or AC repair contractor right away.

• Clogged Condensate Drain Line

The most common reason for water leaking from an AC unit is a clogged condensate drain line. As your AC cools the air, it creates condensation that should drain away. If the line is blocked by dirt, algae, or debris, water backs up and leaks out of the unit.

 

• Frozen Evaporator Coil

A frozen evaporator coil can lead to water pooling inside the unit. This usually happens due to low refrigerant levels, restricted airflow (often from a dirty filter), or thermostat issues. When the ice melts, the excess water has nowhere to go but out of the system.

 

• Dirty or Clogged Air Filter

A dirty air filter restricts airflow, causing the evaporator coil to freeze. When the coil thaws, it can overflow the drain pan, resulting in leaks. Regularly changing your air filter is a simple way to prevent this problem.

 

   1. Damaged or Rusted Drain Pan

Older AC units (typically 12–15 years old) may have a rusted or damaged drain pan. If the pan can’t hold water, it will leak into your home. Replacing the drain pan is necessary to fix this issue.

 

   2. Malfunctioning Float Switch

The float switch is designed to shut off your AC if the drain pan fills with water. If this switch fails, water can build up and leak out of the unit.

 

   3. Leaking Refrigerant Lines

Corroded or cracked refrigerant lines can cause both refrigerant and water leaks. This not only leads to water damage but also affects your AC’s cooling performance.

 

   4. Damaged Gaskets and Seals

Worn-out gaskets and seals can allow water to escape from your AC unit, especially as the system ages.

• Prevent Water Damage: Leaks can cause significant damage to your walls, ceilings, and floors if left unchecked.
• Avoid Mold Growth: Standing water from leaks creates the perfect environment for mold and mildew, which can harm your indoor air quality and health.
• Protect Your Investment: Prompt repairs extend the life of your AC system and help you avoid expensive replacements.
• Professional Diagnosis: An experienced technician can quickly identify the root cause and provide a lasting solution, whether it’s a simple fix or a more complex repair.
