The answer to 'thermostat leaking water' is that a leaking thermostat is a common HVAC issue that can have several potential causes. The most common reasons are a clogged condensate line, a cracked thermostat housing, or issues with the thermostat's internal components.
If you notice water leaking from your thermostat, the first step is to check the condensate line that drains excess moisture from the HVAC system. This line can become blocked with dirt, debris, or even mold, causing water to back up and leak out. You may be able to clear a clogged condensate line yourself, but if the issue persists, it's best to call an HVAC technician to properly diagnose and resolve the problem.
