Common Causes of AC Leaks in Savannah
AC leaks are among the most frequently reported HVAC problems in Savannah, GA, where high humidity means air conditioners pull large volumes of moisture from the air every day. The most common culprit is a clogged condensate drain line: algae, dust, and debris accumulate inside the drain pipe, blocking water flow and causing the drain pan to overflow onto the floor. A secondary cause is a frozen evaporator coil — low refrigerant or restricted airflow causes the coil to ice over, and when the ice melts it produces more water than the drain system can handle in a short period. Less commonly, a cracked or corroded drain pan, a failed condensate pump, or loose refrigerant line insulation can also produce visible water at or near the indoor unit.
Factors That Affect How Serious an AC Leak Is
Not every AC leak carries the same risk or repair cost. These factors help determine how urgently you need professional service.
Older air conditioning systems often have corroded drain pans and brittle condensate lines that are more prone to cracking, making leaks harder to fully resolve without partial component replacement.
Systems that receive regular seasonal tune-ups are far less likely to develop clogged drain lines or dirty coils, which are the two most common drivers of water leaks in Savannah homes.
The city's subtropical humidity means your AC produces significantly more condensation than units in drier climates, putting extra stress on drain components every summer cooling season.
An undercharged system causes the evaporator coil to run too cold, leading to ice formation and eventual water overflow — a leak symptom that points to a refrigerant issue rather than a drain problem.
Air handlers installed in attics or tight closets are more difficult to access for drain clearing, and a leak in these locations can damage insulation, drywall, and ceilings before it is noticed.
Should You Repair or Replace After a Leak?
A leak itself is usually a repairable issue, but it can reveal deeper problems with your system. Use these considerations to decide your next move.
Repair the System
If your AC unit is fewer than ten years old, the leak stems from a clogged drain or minor component failure, and the quoted repair cost is reasonable relative to the system's value, repairing is typically the practical choice.
Evaluate Replacement
If your unit is older, has needed multiple repairs in recent seasons, or the leak is related to a failing compressor or severely damaged coil, a replacement estimate is worth requesting alongside any repair quote.
Ask About a Maintenance Plan
After repairing a leak, enrolling in a seasonal maintenance plan helps prevent recurrence by keeping drain lines clean, refrigerant levels correct, and coils free of buildup throughout Savannah's long cooling season.
