The answer to 'preventive maintenance leaking water' is that a leaking water issue is often caused by problems with the HVAC system's condensate drain line. This line is responsible for removing excess moisture from the system, and if it becomes clogged or damaged, it can lead to water leaks. Common symptoms include water pooling around the indoor unit, water stains on walls or ceilings, and mold or mildew growth.
To address this issue, homeowners can try some basic troubleshooting and maintenance steps, such as checking the drain line for clogs, cleaning the condensate pan, and ensuring the line is properly sloped to allow for proper drainage. However, if the problem persists or requires more extensive repairs, it's best to call a professional HVAC technician to diagnose and fix the issue.
