AC Leaks: Causes, Prevention & Repair Solutions

As a homeowner, dealing with an air conditioning leak can be a frustrating and costly experience. Understanding the causes of AC leaks, as well as how to prevent and repair them, can save you time, money, and stress. In this blog post, we will discuss five common causes of AC leaks and provide tips on how to prevent them from happening in your home.

1. Clogged Condensate Drain Line

A clogged condensate drain line is one of the most common causes of AC leaks. Over time, dirt, dust, and other debris can accumulate in the drain line, causing it to become clogged and preventing the condensate from draining properly. When this happens, water can back up into your AC unit and cause a leak. To prevent a clogged condensate drain line, make sure to regularly clean and maintain your AC unit.

This includes:

  • Changing the air filter every 1-3 months
  • Cleaning the evaporator coil annually
  • Inspecting and cleaning the condensate drain line regularly

2. Frozen Evaporator Coil

A frozen evaporator coil can also cause an AC leak. When the coil freezes, the ice can melt and cause water to leak from your AC unit. A frozen evaporator coil is often the result of low refrigerant levels or poor airflow.

To prevent a frozen evaporator coil, make sure to:

  • Keep your air filter clean and change it regularly
  • Ensure your AC unit has the proper amount of refrigerant
  • Keep vents and registers open and unobstructed

3. Damaged or Disconnected Drain Pan

The drain pan is responsible for collecting condensation that comes from your evaporator coils and redirects this condensation to a drain pipe. If the drain pan is damaged or disconnected, water can leak from your AC unit.

To prevent a damaged or disconnected drain pan, make sure to:

  • Inspect the drain pan for cracks or damage during regular AC maintenance
  • Ensure the drain pan is properly connected to the drain line

4. Improper AC Unit Installation

Improper installation of your AC unit can also cause leaks. If your AC unit is not level or if the condensate drain line is not properly connected, water can leak from your AC unit.

To prevent improper AC unit installation, make sure to:

  • Hire a professional HVAC technician, like those at G2 AC & Heat, to install your AC unit
  • Ensure your AC unit is level and properly connected

5. Damaged or Worn Seals

Over time, the seals in your AC unit can become damaged or worn, allowing water to leak from your AC unit.

To prevent damaged or worn seals, make sure to:

  • Inspect the seals during regular AC maintenance
  • Replace damaged or worn seals as needed
