Air conditioning units make hot, sticky days and nights more bearable for
homeowners throughout central Indiana. Leaky air conditioners, on the
other hand, can become a headache for these same households, often causing
The moisture that drips out of an air conditioner generally comes from
the condensation that builds up on the air conditioner’s evaporator coils.
Although this moisture is supposed to drip into a drain, it drips into
an overflow pan when this drain is clogged. If the overflow pan is clogged
or the moisture is dripping too fast, water can drip out of this pan as well.
Excess moisture dripping from an air conditioner is not only annoying,
but it can also have some disastrous effects if it isn’t taken care
of promptly. Wet conditions can contribute to fungus and mold growth,
for example, and over time, moisture can also cause wood to rot, resulting
in structural damage.
Here are a few things that homeowners can do to prevent moisture damage
from their air conditioners.
- Keep shrubs and tall grasses away from outside air conditioner condenser
units. Obstructions such as these can cause the air conditioner to work
overtime, which can cause ice to build up on evaporator coils. When this
ice melts, there is an excess amount of moisture that can leak out of
the drain or overflow pan.
- Change air filters regularly to keep the A/C unit running as it should.
- Install a safety float switch in the emergency drain pan. When the drain
pan fills up to a certain level, the float will rise, causing the A/C
unit to shut off.
- Arrange for annual inspections of your home’s air conditioner. During
these inspections, a heating and cooling specialist will check to see
if the refrigerant levels are low and if the coils need cleaned. He will
also check to see if there is any obstruction in the drains as well.
