Your air conditioning vent serves an important role in your HVAC system including maintaining air pressure, filtering out debris, and lowering energy costs. Even with these facts, it’s still the most neglected parts of your unit.
Take a look at your vents and see if you spot yellow stains and mold formation. These are caused by water leaks and pose a danger in your safety and comfort. Read on to identify what causes water leaking in your A/C vents.
Clogged Condensate Drain Line
Your condensate drain line is responsible for carrying out the moisture produced by the evaporator coils. When the drain pipe is clogged by mold, algae, and sludge, it pushes the water back into the pan and causes it to overflow from your A/C vent. As a resolution, you can clean the condensate drain line or contact an HVAC repairman immediately.
How to unclog your condensate drain line? Just follow these steps:
- Be sure to turn off the power source before you start
- You can use a stiff, thin brush to clear the clog in the drain line
- Attach the dry or wet vacuum at the end of the drain line and let it suck out other debris
- Empty the drain pan. You can use soap or vinegar to clean it
Dirty Air Filters
Dirty air filters can cause your A/C to freeze up because the air is obstructed by dirt, dust, and other particles. When your unit is turned off, the ice buildup in the coils will start to melt and will result in water leaks. Replace your air filters every three months. Experts recommend getting air filters with a higher MERV rating as it will last longer.
Broken Sump Pump
A sump pump is usually located in the basement or next to the furnace. It collects the water from your unit and sends it out. This machine helps in keeping the area dry and prevents it from flooding. If the pump motor is not working properly, it will not be able to drain the water from your drain line. Thus, water leaks can occur in your A/C vent.
What you can do is to check the float switch for any scum or limescale buildup. Try to clean the bucket with bleach and remove any mold or mildew. If you’re not comfortable doing it, feel free to call us at LoveJoy HVAC.
Low Refrigerant Level
The low refrigerant level can form ice buildup in the coil, which is another source of water leaks as soon as the ice melted. Also, exposure to refrigerant leaks is alarming because of the chemicals, putting your health and safety at risk. Seek immediate help from a licensed repairman to get it fixed promptly.
