Why is My Air Conditioner Leaking

By April 3, 2023April 29th, 2023One Comment

If you notice water or moisture around your air conditioning unit, it’s a sign that your AC may be leaking. An AC leak can be caused by a variety of factors, and it’s essential to address the issue promptly to avoid costly damage to your home. Here are some common reasons why your air conditioner may be leaking:

  1. Clogged Condensate Drain Line The condensate drain line is responsible for removing excess moisture from your AC unit. Over time, this drain line can become clogged with dirt, dust, and debris, causing water to back up and leak from your unit. Regular maintenance, including cleaning and unclogging the drain line, can help prevent this issue.
  2. Dirty Air Filter A dirty air filter can restrict airflow and cause your AC unit to work harder than it should, leading to excess condensation and potential leaks. It’s important to change your air filter regularly, at least once every three months, to ensure that your AC unit is running efficiently.
  3. Low Refrigerant Levels If your AC unit is low on refrigerant, it can cause the evaporator coil to freeze, leading to excess moisture and potential leaks. Low refrigerant levels could be caused by a leak in the system, and it’s essential to contact a professional HVAC technician to diagnose and repair the issue.
  4. Damaged Condensate Pan The condensate pan is located underneath the evaporator coil and is responsible for collecting excess moisture. If the pan is damaged or cracked, it can cause water to leak from your AC unit. A professional HVAC technician can inspect your condensate pan and recommend repairs or replacement if necessary.
  5. Improper Installation If your AC unit was not installed correctly, it can lead to a variety of issues, including leaks. It’s essential to have your AC unit installed by a licensed and experienced HVAC technician to ensure that it’s installed correctly and functioning efficiently.
