Water leaks from the air conditioner on rainy days. If the outdoor unit is installed on the rooftop or the rain trap (U trap) of the connecting pipe is not installed, Rainwater can flow into the room through the hole which connects the indoor unit with the air conditioner. Check how the connecting pipe is installed.
As soon as the monsoon arrives, water starts dripping from the split AC installed in the house, due to the humid weather and high humidity in the air. The indoor unit of the split AC accumulates water during the rainy season, causing it to start dripping inside the house.
Check for trapped condensate line or a plugged condensate pan. Inspect drain pan to see if has developed a leak. During heavy rain, water can build up beneath drain pan. Inspect for mold. Check airflow across the cooling coil. If moving too fast it can carry condensation of coils and into duct system. Inspect attic.
To prevent an air conditioner from leaking water inside and outside its case, ensure regular maintenance, including cleaning or replacing the air filter and clearing the condensate drain line to avoid blockages. Check for proper installation with a slight tilt towards the outside to allow proper drainage.
Drainage Problems: The A/C system has a drainage system to remove condensation. If this drain becomes clogged or obstructed, heavy rain could exacerbate the issue, leading to water backing up and causing the A/C to turn off.
If you're concerned about rain on your air conditioner, don't be. Rain does not threaten your unit and can even clear out clogged debris from the inside of your unit. It is this debris that poses a great threat to your unit as it can block airflow and wear down important pieces.
So when it's raining outside, leave the tarp alone. If you still feel like covering up your unit for air conditioner rain protection, most manufacturers offer custom covers made with breathable material to give you peace of mind. Storms can make stuff fly around outside.
You should shut off your air conditioner immediately if you see any signs of leakage. If there is excessive moisture inside your home, it could cause serious health problems. Mould growth can cause respiratory issues, headaches, nausea, and even asthma attacks. If you see any leaks, call an HVAC technician right away.
To unclog an AC drain line, turn off the power to the unit. Locate the drain line and use a wet/dry vacuum to suck out the clog. Flush the line with water using a garden hose or cup of water. Check and clean the drain pan under the indoor unit.
Under normal operation, your air conditioner should only leak or produce condensation while operating. Then, the small puddle of water should dry up on a hot day. A telltale sign you could be in need of air conditioner repair is if the water leak persists for a day or more.

How do I find my AC drain line? Your AC has a condensate drain line running from the indoor to the outdoor unit. You'll find the end of the drain line somewhere near the outdoor unit (usually a copper or white PVC pipe). As for the access point, look for a vertical pipe with a cap near the indoor unit.
Increase the fan speed or use a less restrictive filter. That'll lower the delta between supply and return hopefully keeping duct work at a higher temp. Your system might be short cycling as well due to oversizing. Increase thermostat swing to get rid of more moisture.
In midsummer when temperature is high, "cooling operation" is appropriate, but in rainy season when humidity is high, "dehumidification operation" is recommended.
The most common cause of AC leaking water outside or inside at home is because your unit has a clogged condensate drain line. Often, the condensate line gets clogged with dirt and dust that passes through it. Over time, it mixes with the moisture of the air conditioning unit and sticks to the sides of the drain line.
One of the most obvious signs is a puddle of water in your AC's drain pan, which proves the water isn't draining as it should. Other signs include: Standing water near your air conditioner's condenser unit. A moldy smell around the drain or from your system's vents and registers.
Clogs in the condensate drain line cause moisture to back up in the air conditioner, which can be damaging. The repair cost to have the drain line flushed runs between $75 to $250. If replacement is needed because the condensate drain line is damaged, a new condensate drain line is usually only around $20.
Over time, this line can become clogged with algae, dirt, dust, and debris. When this happens, the line backs up and overflows from the drain pan, causing the water to leak into your home. You can unclog the drain line by removing the debris with a wet/dry vac.
As soon as you notice that your air conditioner is leaking, go ahead and turn it off. This is important even if the air in your home doesn't feel any different, because it will stop the flow of water. The more water leaks out of your air conditioner, the more susceptible it becomes to further damage.
A leak from your air conditioner can cause significant damage to the system. Whether there's more moisture on or near your AC than usual or water is ponding near the drain line, consider it an emergency. The damage from water can quickly escalate and spread to nearby equipment, materials, and furnishings.
Can the rain potentially damage your AC unit, and should you prepare for more frequent AC repair calls? The quick answer is no. The rain itself cannot damage your AC unit. Outdoor units can withstand intense weather, including frequent thunderstorms.
The cost to replace a drip pan on an AC unit ranges from $200 to $600. Typically, the drip pan is part of the evaporator coil so most of the time we need to change the coil as well. That can cost over $2000. If the pan is in an air handler or a package unit, we can often replace for approximately $500.
Storm Damage: Even though heavy rains cannot damage your AC unit, the winds accompanied by the same rain can leave dirt, leaves, twigs, and other debris to damage the condenser fan grille. Even objects falling on your unit, such as tree branches, from the storm can cause damage.
