Most AC vents produce a little bit of condensation during normal operation. However, excessive water dripping from your AC vents could indicate a larger problem.
So today, the team at Air & Energy of NWFL presents some common causes of water dripping from AC vents. We will discuss common air conditioner problems and how to fix them.
Let's review some common reasons for water dripping from your AC vent.
Dirty Air Filter
Air conditioners cool your home by drawing moisture out of the air and draining it through condensate lines. Clogged air filters trap moisture in your system, so the condensation might freeze over your coils instead.
How often you need to replace your dirty air filters depends on the size of your unit and house as well as usage conditions. Generally, you should change your HVAC system filter at least once every six months.
Frozen Evaporator Coils
The evaporator coil plays a crucial role in removing heat from the air conditioner system. Restricted air flow can cause frost to form over your coils, reducing their effectiveness.
Frozen evaporator coils melt and leak all over the interior of your indoor air handler. You can clean the frost from coils yourself, but you will need to call an expert if the problem persists.
Clogged Condensate Drain Line
The condensate drain line works to remove condensed water from the AC unit. Typically, water drips into the drip pan, and the condensate drain line removes it to the exterior of your home.
Dirt, debris, mold, and algae can cause a clogged condensate drain line and water leaks. You can clean a clogged drain line yourself with a high-powered shop-vac and vinegar cleaning solution.
Cracked Drip Pan
Over time, the drain pan in the AC drain line can rust and eventually crack.
Generally, the drip pan sits under the evaporator coils of your AC system and collects moisture. A cracked drip pan will leak water from the bottom of your air ducts.
If your drain pan cracks, you'll need to replace it. An AC repair expert can find and install a compatible model.
Broken Condensate Pump
After condensate goes through the main condensate line, it collects in a condensate pump that removes it from the air conditioning system. As long as the pump is active, it prevents water backflow and overflow.
If the condenser unit malfunctions, water will leak out of the top into your air vents. Some air conditioner models will automatically shut off the system if the pump fails to prevent overflowing.
Refrigerant Leak
Coolant liquid plays a crucial role in removing heat from your home and producing cold air. Refrigerant leaks can occur if your coolant lines sustain damage or get clogged.
If you notice a refrigerant leak, make sure you call an expert. AC refrigerant can pose a health hazard, and you'll need special tools to replace the coolant and fix the damage.
Improper Installation
Water leaking from your air vents could also result from improper installation. If the drain pan is crooked or the condensation lines don't have the proper angle, your system can leak water.
This Homeowners commonly see this problem in newer systems, but it can occur in older systems too.
Leaks in Air Ducts
AC vents can also drip water due to an air leak in your duct system. Cracks in your ducts can collect condensation and drip water into your house.
You can check for air leaks by inspecting the joints of your ducts. If you find a leak, you will need to caulk the gap.
Insufficient Insulation
Insulation in your walls and attic help remove moisture from your home by controlling heat transfer. Poor insulation can cause moisture build-up, leading to puddles and leaks.
Fortunately, you can easily fix insulation if you have access to your attic. Check around your AC vent to see if it has any gaps in coverage between the vents and the walls.
Plumbing Leaks
If none of the above causes explain water leaking from your AC vent, the problem could stem from a leak in your plumbing system.
Double-check all water sources from plumbing applications and call a relevant expert if you find issues.
Tips To Prevent Water Leaking From Your AC Unit
Below we share some tips on how homeowners can prevent the likelihood of water leakage.
Change air filters regularly
A clean air filter won't restrict cool air flow and create humid air. If your air conditioner only produces warm air, the filter probably needs replacement.
Check condenser and evaporator coils regularly
If you have a frozen evaporator coil, you can gently remove the frost with a soft-bristled brush.
Vacuum your home frequently.
Dirt and other debris like pollen, pet dander, and dust can easily clog your air filters and air vent. Regular vacuuming will help your air filter last longer.
Flush your drain lines
Flush drain lines with a vinegar cleaning solution every six months. Vinegar will eat away any mold or algae growing in a clogged condensate line or AC vent.
Visual inspection
Get in the habit of visually inspecting your vents every few months. If you notice leaks in an AC vent, follow it to the source and address the problem.
Regular maintenance
Make sure to follow your AC system maintenance schedule. Regular maintenance keeps your hardware components in good condition, so your air conditioner will perform better for longer.
Water leaks
If you do find water leaks, make sure to clean them promptly and stop further damage. Lay down some towels to catch leaking water, and call an expert.
