When you have an AC unit installed in your house, it can be disconcerting to see messy floors or walls due to water leaks. However, leaking water is a serious issue that should be addressed promptly and may come about when excess moisture accumulates in your condensing unit. Additionally, using the unit while it's leaking can cause it to malfunction due to water accumulation. Here are four possible explanations for why your indoor cooling unit is leaking water:
Frozen Evaporator Coils
The evaporator coils can freeze for several reasons, including refrigerant leaks, accumulation of dirt in the filter, or airflow blockage. When they freeze up, the moisture will likely build up in the indoor unit and cause an overflow in the drain pan. This, in turn, causes the water to start seeping from the unit. Since you cannot rectify this problem without help from a specialist, you need to engage the services of an HVAC technician to fix the problem.
Incorrect DIY Installation
If the unit is newly installed, and you notice dripping water, it might be due to an improper DIY installation. For instance, the installed drain pipes could be disproportionate, which disrupts the drain pan's water flow, causing water to drip from the unit. Moreover, if the central unit is not level, water starts to drip and mess up your home. Ensure that you hire an HVAC professional to install new units in your home.
Rusty or Damaged Drain Pan
The drain pan's function is to hold the condensation as it trickles down, and the water that accumulates in the pan then flows into the drain line. Thus, if the pan is rusty or corroded, the water leaks instead of flowing to the drainage line. To resolve this, the HVAC pro will likely recommend that you replace the corroded drain pan, especially if the unit has been in use for more than 15 years.
Condensation Build-Up
Condensation is generally expected due to the process of dehumidification. However, excess condensation build-up is problematic because it causes water to seep out of the vents or air ducts. This build-up could be due to high humidity, dirty air filters, or clogged air ducts. Unfortunately, it causes mold to grow on air ducts, and indoor air quality deteriorates. Nonetheless, a technician can fix the water leakage issues and restore effective functioning.
These are some reasons why the AC unit leaks water, and each requires your swift response. As such, you should book an appointment with an HVAC service such as Advanced Air Conditioning and Heat so that they can fix the problem efficiently.
