Technician checking out air conditioner

An air conditioner leaking water is not an uncommon occurrence. When it is hot outside, a working air conditioner is essential to keep the house cool. Although the unit will continue working, its efficacy will be severely compromised. The air conditioner should be promptly repaired before the moisture causes costly water damage. Here are possible reasons the AC unit leaks water.

An indoor AC is built with evaporator coils that cool the warm air drawn into the unit. The warm air blowing over the cold evaporator coils produces condensation and reduces humidity. The accumulated moisture is released into a drain pan, then into a condensate drain line leading outside the home.

Since the condensate drain line leads to the outside of the building, homeowners should not face AC leaks inside the home. Problems occur when large amounts of moisture accumulate, and the unit is unable to remove the excess water. As a result, the AC will leak water inside the home.

1. Unmaintained Condensate Drain Line

An air conditioner may be unable to eliminate the surplus moisture for a number of reasons. One common cause of this issue is due to a clogged condensate drain line. The blockage occurs when debris and dirt are collected by the AC during the dehumidification process.

When the condensate drain line is left uncleaned for prolonged periods, this dirt and debris will gather and lead to a clog. The water collected by the AC unit will eventually spill out of the drain pan and into the interior parts of the home.

2. Aging Drain Pan

The drain pan catches moisture from the evaporator coils. A rusty or damaged drain pan delivers subpar performance and allows water to leak instead of travel into the drain line. An AC unit that is 15 to 20+ years old will show signs of wear, such as rust and corrosion.

3. Disconnected Drain Line

An improperly connected drain line can detach, thereby leading to leaks inside the 1. The problem in the drain line can be caused by unprofessional installation or after an improper repair. Or, the drain line may simply become loosened over time, leading to pooling water.

4. Broken Condensate Pump

Pushing water out of a drain line is difficult when the AC is in a basement or attic; it thereby requires a condensate pump to remove the water and drain it outside. If the pump breaks or the float switch malfunctions, it will not pump the water and instead leak.

5. Dirty Air Filters

Air filters promote optimum air circulation, trap pollutants, and deliver clean air to the home. Clogs can occur when dust particles accumulate in the filters over time. Airflow is significantly reduced, and warm air fails to pass through easily. The evaporator coils freeze: when they thaw, water leaks occur.

6. Improper Installation

An incorrectly installed AC unit can leak water. The air conditioner and drainpipes should be installed proportionally; but when they are not, the flow of water from the drain pan is disrupted and a leak develops. Similarly, when the AC is not leveled, water will spill into the home.

7. Low Refrigerant Level

Evaporator coils can freeze when the volume of refrigerant decreases and the pressure inside the air conditioner correspondingly lowers—a leak subsequently occurs. Signs of low refrigerant include a hissing or bubbling sound; additionally, the unit may fail to cool the house as it should.

8. Cold Outdoor Temperatures

An air conditioner is designed to operate in warm weather. Running the unit when the outside temperature is 60 degrees Fahrenheit or lower can result in frozen evaporator coils. Once the coils thaw, the flow of water could be obstructed by ice and lead to an overflow.

The above AC unit problems have practical solutions. A clogged condensate drain line can be cleaned by scrubbing it with a long wire brush and pouring bleach down it every six months. Replace a worn drain pan with one that that meets the size requirements of the air conditioning unit.

A disconnected drain line should be reconnected by an HVAC professional. Similarly, contact a qualified service professional to repair a broken condensate pump. Replace dirty air filters, ideally every three to four months; and clean them every two weeks or more often during the peak operating season.

Installation of the AC unit should be done by an experienced professional. Seasonal maintenance is sufficient to maintain the right level of refrigerant; normally, a refrigerant does not require refilling unless there’s a leak. Persistent water leaks due to cold outdoor temperatures should be handled by AC experts.

Water Damage Restoration Company

When an air conditioner leaks water inside the home, serious water damage can result. Delaying repairs of the water leak can trigger mold growth. Moisture that is left unaddressed can lead to warped floors, rotting wood, and other structural damages. ServiceMaster EMT can stop the spread of water damage.
