A drip or two of water leaking from under your car is normal, but if it is increasing in frequency and volume, your car needs to be checked.
But any water draining from your car AC should be a drip, not a waterfall! Any more than a saucer-sized patch is a concern.
Normal condensation comes from the evaporator, so it is likely the problem originates from this part of the system. Water inside the car can be problematic as it can cause mould and mildew which is harmful to breathe in.
So, how much water should drain from an air conditioner? On average, a functioning air conditioner in a typical home can drain anywhere from five to 20 gallons of water per day. Keep in mind that these numbers are ballpark figures, so don't feel alarmed if your unit shows slightly different behavior.
Many times when the vehicle's air conditioner is in use, there will be water dripping from the condenser's drain visible under the vehicle, which is perfectly normal. The window air conditioning units in the house will also allow condensed water to drip to the ground and is a natural part of the unit's operation.

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.
There is no easy answer to how much condensation from your HVAC system is “normal.” In most cases, a small amount of condensation is nothing to worry about. However, if you notice a significant increase in the amount of water around your HVAC unit, it could be a sign of a problem.
If this service isn't done regularly, you could potentially experience an AC drain line clogged. A clogged AC drain line symptoms include: Musty, moldy smell near your indoor unit or in air from the registers/vents. Standing water near the indoor unit.
The real issue with condensation is that it can lead to black mould. Patches of black mould around windows, on doors and on walls doesn't just look unsightly, it could be making you seriously ill. The main symptoms from mould are: Stuffy nose.
A few drops of water leaking from underneath your car is most often a normal occurrence. When it's uncomfortable outside and you have the A/C on full blast to keep you from melting into a puddle on the sidewalk, your cooling system is working harder than normal.
Low Refrigerant Charge
If your system is low on refrigerant, this can also cause the evaporator coil to freeze, which likewise can result in an overflowing condensation pan as ice melts.
Another sign that the AC in your car might be leaking is if you notice stains or moisture around the air conditioner. For instance, if you find oily-looking stains near the compressor, condenser, or hoses, you likely have a refrigerant leak on your hands. Refrigerants often appear oily.
Dirty or Blocked Air Filters
When your AC's air filter accumulates debris, it may become blocked. This may freeze up the car air conditioner's evaporator coils, which will cause excess water to overflow from the condensate drain.
It's completely normal for your AC to drain 5-20 gallons of water outside of your home (via the condensate drain).
Your car leaking water, especially near the back of the vehicle, is normally caused by air conditioning condensation or exhaust condensation. Both of these kinds of leaks are normal. Your biggest concern should be if the liquid isn't water, but there are easy ways to test that in your Arlington home.
You see water on the floorboards.
Your AC has a drain hose that directs excess moisture away from the evaporator coils and out the undercarriage. If this hose is clogged, condensation will accumulate in the unit and begin dripping into the cabin.
If the air conditioner is not properly draining water, it indicates that there is a leak occurring somewhere else in the system. To address this issue, it is crucial to rely on the expertise of a skilled technician who can first identify the problem among the potential causes.
Most AC system condensation issues stem from improper drainage. Failure to keep up with routine maintenance and cleaning may lead to drain line issues. For example, your condensate drain line may clog due to a buildup of dirt, mold, bacteria, and debris. This blocking causes water to back up elsewhere in your system.
Condensation occurs when moist air (usually warm moist air found indoors) comes in direct contact with coldersurfaces (e.g. walls, window panes). It is more prevalent at the bottom of external walls and cold corners or in places where moisture stagnates - in areas with little or no ventilation (e.g. behind furniture).
Normally, the amount of condensate that drains from an A/C system can range from 5-20 gallons per day, depending on its size, how long the unit runs and how much moisture is in the air.
Water: if it's water, and you know you've been running the air conditioner or interior heater, it's likely just condensation from the cooling mechanisms. Specifically, the evaporator core leaks water from under the passenger side of the engine compartment when the air conditioner is being used. This is normal use.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
