3 Common Causes Of A Leaky AC Unit


From keeping your home and family cool to removing humidity and maintaining a healthy air quality, your air conditioning system is important for many reasons. Unfortunately, over time, your AC unit will experience stress that affects its function and efficiency. Leaks are a common problem many homeowners face, but you may not realize why your AC unit is leaking and how it can be so problematic. Here are a few common reasons your AC unit is leaking.

Clogged Filter

If you notice puddling around your outdoor AC unit, check the system filters inside your home. These filters are meant to trap dirt, dust, and debris, preventing them from moving into your home's air.

If the filters are dirty and clogged, air will struggle to move through, preventing you from cooling your home, which can cause the evaporator coils to freeze up. When the coils start to thaw, water will start leaking and puddling up around the unit.

Change your filter if you notice water leaking from the unit. However, experts recommend replacing your filter every 3 weeks if you have pets, allergies, or live in a dusty, polluted area.

Low Refrigerant

No matter how great your system is, a small amount of refrigerant will leak out. Unfortunately, you may not even realize your system is low in refrigerant until you are unable to cool your home. Another sign of low refrigerant is water leaking from your outdoor unit.

Again, without sufficient refrigerant, your system will not be able to cool your home, placing pressure on the evaporator coils and causing them to freeze up. Eventually, they will thaw, causing water to leak out of your unit.

If you see water leaking or puddling and you are struggling to cool your home, have your system evaluated to determine if more refrigerant is required.

Damaged Condensate Line

Your AC system has a drain pan and condensate line, which moves excess moisture from the home's air to the outdoors. If the drain pan is old and corroded or algae, leaves, and debris have clogged the pain, the moisture will build up in the actual condensate/drain lines.

If the moisture cannot drain properly, it will build up, damaging the pan and drain lines. This can lead to cracks and other damage, which will allow water to start puddling up around the actual AC unit.

Water leaking from your AC unit is not normal. Therefore, make sure to have your system inspected by an HVAC service to ensure it is repaired and back to a fully-functional state.
