Certified Water Damage Restoration Specialists





Possible Causes of A/C Unit Drain Overflow
A variety of factors can cause your air conditioner’s drain line to become clogged or overflow. One of the most common issues is the accumulation of dirt, dust, and algae inside the drain line. Over time, this buildup can block the flow of water and cause the drain to back up.
Another possible cause is a faulty condensate pump. If the pump fails to properly expel the water from the A/C unit, it can lead to overflow. Additionally, low refrigerant levels or frozen coils can create excess condensation that overwhelms the drain system, leading to water pooling around the unit.
Improper installation or maintenance of the A/C system can also contribute to drainage issues. If the unit is not pitched correctly or the drain line is too narrow, the water may not flow properly, resulting in overflow. Finally, old or damaged pipes can crack or break, allowing water to leak out and create a mess in your living space.
How We Can Fix That
At St. Louis Water Damage Pros, our team of certified technicians is equipped to handle A/C unit drain overflow quickly and efficiently. The first step we take is a thorough inspection of the A/C system to identify the root cause of the problem. We check for blockages in the drain line, examine the condensate pump, and inspect the surrounding area for any signs of water damage.
If we find a clog, we use specialized tools to clear the drain line and restore proper water flow. For more complex issues, such as a faulty condensate pump or frozen coils, we can make the necessary repairs or replacements to get your A/C unit functioning properly again. In some cases, we may need to adjust the pitch of the unit or replace damaged pipes to prevent future drainage issues.
Once we’ve fixed the issue, we also offer comprehensive water damage restoration services. If any part of your property has been affected by standing water, we use advanced drying equipment to ensure all moisture is removed, preventing mold growth and further damage. Our team works efficiently to minimize downtime and get your home or business back to normal.
