A leaking AC unit is not only frustrating, but it can also lead to more significant problems if left untreated. This blog post will explore the common causes of a leaking AC unit and how to fix them.

Clogged Drain Line:

One of the most common causes of a leaking AC unit is a clogged drain line. The drain line carries condensation from your AC unit outside, but if it becomes clogged with dirt, dust, or debris, water can back up and leak inside your home. To fix this issue, you'll need to clear the drain line. This can be done by using a wet/dry vacuum to suck the debris out of the line.

Frozen Evaporator Coils:

Another common cause of a leaking AC unit is frozen evaporator coils. Evaporator coils are responsible for removing heat and humidity from the air inside your home, but if they become too cold, they can freeze over and cause the AC unit to leak. To fix this issue, turn off your AC unit and allow the coils to thaw out. Once the coils have thawed, clean the air filter and make sure your refrigerant levels are correct.

Blocked Condensate Pump:

If your AC unit has a condensate pump, it can become blocked with dirt, dust, or debris, causing water to leak out of the unit. To fix this issue, turn off your AC unit and clean the pump by removing the cover and wiping away any debris. If the pump is damaged, you'll need to replace it.

Clogged Air Filter:

Finally, a clogged air filter can also cause your AC unit to leak. When the air filter becomes dirty, it restricts airflow, causing the evaporator coils to become too cold and freeze over. To fix this issue, replace your air filter every few months, depending on how often you use your AC unit.

When to Consider Professional AC Repair Services:

While some air conditioning issues can be resolved with simple DIY steps, there are circumstances when calling in a professional is the safer option. Professionals are equipped with the right tools, training, and experience to handle more complex problems such as refrigerant leaks, electrical issues, or extensive damage to your unit. If you're ever in doubt about the severity of an issue or lack the confidence to fix it yourself, don't hesitate to contact a licensed HVAC technician.
