Dealing with AC Leaks: Causes, Prevention & Repair

Dealing with air conditioning leaks can be frustrating, especially during the hot summer months in Gainesville, FL. In this guide, we will discuss the common causes of AC leaks, how to prevent them, and the best ways to repair them. By understanding these issues, you can keep your home cool and comfortable while avoiding costly repairs.

Causes of AC Leaks

There are several reasons why your air conditioner may be leaking.

Some common causes include:

  • Blocked or damaged drain line: The drain line is responsible for removing excess condensation from the air conditioning unit. If it becomes blocked or damaged, water can back up and cause a leak.
  • Dirty or frozen evaporator coils: The evaporator coils are responsible for cooling the air that passes through the unit. If they become dirty or freeze, the coils can cause excess condensation and lead to a leak.
  • Low refrigerant levels: Low refrigerant levels can cause the evaporator coils to freeze, leading to excess condensation and a leak.
  • Cracked or damaged drain pan: The drain pan collects excess condensation from the unit. If it becomes cracked or damaged, water can leak out of the air conditioner.

Preventing AC Leaks

There are several steps you can take to prevent AC leaks and keep your air conditioner running smoothly:

  • Regular maintenance: Regularly maintaining your air conditioner can help prevent leaks and other issues. This includes cleaning the evaporator coils, checking refrigerant levels, and inspecting the drain line and drain pan. 
  • Change your air filter: A dirty air filter can restrict airflow, causing the evaporator coils to freeze and potentially leading to a leak. Be sure to change your air filter regularly, according to the manufacturer's recommendations.
  • Inspect your drain line: Regularly inspect your drain line for blockages or damage. If you notice any issues, address them promptly to prevent a leak.
  • Keep your AC unit level: An uneven air conditioner can cause the drain pan to tilt, leading to a leak. Make sure your unit is level to prevent this issue.

Repairing AC Leaks

If you discover a leak in your air conditioner, it's important to address the issue promptly to prevent further damage and keep your home cool and comfortable.

Here are some steps to take when repairing an AC leak:

  • Turn off the air conditioner: If you notice a leak, turn off your air conditioner immediately to prevent further damage.
  • Identify the cause of the leak: Inspect your air conditioner to determine the cause of the leak, whether it's a blocked drain line, dirty evaporator coils, low refrigerant levels, or a damaged drain pan.
  • Repair or replace damaged components: Depending on the cause of the leak, you may need to repair or replace damaged components. For example, if you have a blocked drain line, you may need to clear the blockage or replace the line if it's damaged. If your evaporator coils are dirty or frozen, you may need to clean them or replace them if they're damaged.
  • Call a professional: If you're unsure how to repair your air conditioner or the issue persists after attempting repairs, it's important to call a professional HVAC technician for assistance.
