If you want to keep your air conditioning system running smoothly, it should get regular maintenance by a professional central heat and air technician. Otherwise, it will be vulnerable to problems that can affect its performance. One problem you may already experience is a water leak, which is noticeable by water stains and puddles beneath the indoor unit. It can happen because of several factors, including:
Low Refrigerant Levels
Sometimes, having low refrigerant in the system can also affect the pressure inside the AC unit. When this happens, the evaporator coil can easily freeze, leading to leaks in the system. This can compromise indoor air comfort. Other signs of low refrigerant include bubbling or hissing sounds while it’s in use. If you already hear this every time you turn on your AC, don’t hesitate to call your trusted technician to resolve the issue.
Damaged Drain Pump
This type of problem is often confused with a clogged drain line, but this is a separate part of your system that pulls water from the overflow pan. If the water overflows and drips directly from the air conditioning unit, the component doesn’t work properly. Talk with your professional air conditioning and heating repair technician immediately to prevent further damage to the system.
Drain Line Problems
If the HVAC technician determines the drain pump is working, then the AC leaks may be caused by a clogged drain line. Clogs prevent water from escaping properly and will get backed up, forcing the condensation to overflow and leak indoors. You can try fixing this with a wet/dry vacuum, but if it still doesn’t drain properly, your AC will likely need professional attention.
Damaged Overflow Pan
An AC leak may also be because of cracks at the bottom of the overflow pan. It can be patched with a specialized tape or adhesive, but this is only seen as a temporary solution and won’t always stop the leaks. Depending on the extent of the damage, your technician may consider replacing the overflow pan with a new one.
