The answer to 'AC repair leaking water' is that the most common causes are a clogged drain line, a malfunctioning condensate pump, or a refrigerant leak. Symptoms include water dripping from the unit or pooling around the base. Solutions may involve clearing the drain line, replacing the condensate pump, or repairing refrigerant leaks. In many cases, DIY fixes are possible, but for more complex issues or if you're not comfortable working on HVAC systems, it's best to call a professional HVAC technician.
Leaks can occur for a few reasons. A clogged drain line is one of the most common issues, as debris and algae buildup can block the line and cause water to back up and overflow. Another common problem is a malfunctioning condensate pump, which is responsible for pumping out the water that collects in the drain pan. If the pump fails, the water has nowhere to go. Refrigerant leaks can also lead to water leaks, as the low pressure in the system causes condensation to form and drip out.
