Did you find your aircon leaking water as soon as waking up? Undoubtedly, this scenario would be a cause for concern. With all the other bills you worry about, it looks like an air conditioning repair service will add to your expenses. But before you panic, it helps to learn the most common causes of a leaking AC unit and how to troubleshooting leaks aircon. Keep reading to identify the cause of the aircon leaking water and how to fix it with aircon servicing.
1) Leaking around the vent
Most homeowners notice water leaking around the AC vent. Thankfully, this problem is one of the easiest to fix. All you need to do is check whether any air escapes from the sides of the vent. If you find that there’s air escaping anywhere other than the grates, then you need to seal where the air escapes from. Head over to your local hardware store and buy caulk to effectively seal the leak.
2) Condensate drain line
If there’s too much water in the air vent, the probable cause is a clogged condensate drain line. Check the condenser unit and inspect whether the drip pan is overflowing with water. When the condensate drain line gets clogged, there’s nowhere for the water to pass through. You should also observe any signs of rust on the furnace. This is a more serious problem since rusting on the furnace could break down your unit in no time. Call an air conditioning repair company right away to address this problem.
3) Air filter
Another common reason why water leaks around the AC vent is a dirty air filter. The reason for this is that it causes your air conditioning unit to freeze up. When you turn off your unit, the frost melts and the water drips down. If you notice that the frost is minimal, then you could simply change the air filter to fix the issue and restore your unit to its brand new condition.
4) Air ducts
In many homes, the air ducts of AC units run through the attic, which is one of the least insulated spaces in a house. This is a recipe for a leaking aircon. But if you have access to your attic, then you can use an air duct insulation to put an end to the leak. This requires taking off the grate and wrapping the insulation around the vent component. If you’re not comfortable doing this, have a professional do it for you.
5) Sump pump
Have you already cleaned the condensate drain line but there’s still a leak? Your next step should be to check the sump pump. Most modern AC systems come with a float switch which turns on the pump once the water reaches a pre-defined level. You can try flipping this switch to see if it helps. It’s also possible that grime has built up around the switch, rendering it useless. Try cleaning it and then see how your AC unit performs after.
It’s also possible that the root of the problem lies in a refrigerant leak. This is the case for air conditioning units that see a minimal leak. When you have insufficient levels of refrigerant, the unit cannot get rid of humidity from the air. This means any water sucked out of the air stays on the evaporator coils.
7) Evaporator coil
You may also be looking at a frozen evaporator coil. Expect the ice to melt once you turn off the system. The water drips out of the air vents as a result. Replacing the evaporator coils is a complex task. Be sure to leave this in the hands of an air conditioning repair expert to get the job done the first time.
