Why is My AC Leaking Water? Our Experts Explain
Being a homeowner is a wonderful feeling, but it doesn't come without challenges. For instance, have you ever checked your air conditioner and realized it's leaking? If so, you're not alone. AC leaks are a common concern among homeowners, and they can often leave them shaking their heads and asking: Why is my AC leaking water?
Well, wonder no more. Our experts share the causes, risks, and solutions to why your air conditioning is dripping water.
Why Is My AC Leaking Water?
Okay, so you go to check on your AC system and notice a puddle alongside the unit. You scratch your head and ask, "Why is my air conditioner dripping water?" Here are some possible reasons.
Possibility No. 1: Your condensate drain line is clogged.
Your condensate drain line is one of the most essential parts of your HVAC system. A small pipe connects to the drain pan and removes the moisture (or condensation) from the evaporator coil as it cools. If the drain line clogs, it prevents the water from draining and sometimes can overflow—hence the puddling. Helpful tip? First, turn the system off. Next, if you know where the outside drain line is, try using a wet/dry shop vac to suck out the clog (be sure it is sealed tight so you're not pulling out air). Many times, this helps clear the problem! Still having issues? Give us a call.
Possibility No. 2: Your air filters are dirty.
Dirty filters can restrict airflow and sometimes cause your evaporator coils to freeze. Once the ice melts off the coil, it can overwhelm the drain pan and overflow, resulting in leaking or puddling. Solution? Change air filters every three months.
Possibility No. 3: Your refrigerant levels are low.
If your refrigerant levels are low, your evaporator could freeze, leading to leaks and puddles as the ice melts. For safety reasons, call one of our professional techs at Air Experts to replace your refrigerant.
Possibility No. 4: Your drain pan is damaged.
If your drain pan is cracked, rusted, or damaged, water can leak out of the pan instead of draining properly. If you are unfamiliar with your HVAC system and drain line pan, we recommend calling for professional replacement.
Possibility No. 5: You have damaged insulation.
If your insulation is damaged, it can cause condensation and leaks. If you think your insulation is outdated, we recommend upgrading it to see if that helps stop leaks. Need professional assistance? No problem—call us!
