4 Possible Reasons Why Your Air Conditioning Leaks Water

It is unsettling to see water leaking from your air conditioning unit. Even though your air conditioner eliminates moisture from the air, dripping water isn’t a typical scenario. Instead, a leaky AC might signify a serious problem. A leaky AC may cause damage to your floors, ceilings, and walls, as well as problems with its performance and efficiency. This can be the reason for growing mold, which may cause health issues.

If you detect your AC leaking water, turn it off immediately because it may fail due to water accumulation. Leaking air conditioners need professional servicing, so you must contact an HVAC service in your area to avoid bigger problems due to a lack of knowledge and skills. For example, if you live in London, CA or anywhere in southwestern Ontario, you should seek an HVAC London-based company, which can provide reliable, round-the-clock residential service for air conditioner leaks.

Read on to learn about the most common reasons for an AC leak.


Clogged Drain Line

A clogged condensate drain line is one of the most common reasons your air conditioner leaks inside the home. The line can get blocked with particles such as mold, dirt, species of fungi, or dust over time. As a result, water can’t escape and drain to the outside, so the drain line becomes clogged, allowing moisture to return and leak water inside.

Using a wet/dry vacuum to remove debris is a simple technique to unclog the line. It’s supposed to clear out whatever clogs the pipe and allow water to flow freely. However, you may need professional assistance if the wet/dry vacuum approach fails. Professionals use a specialized, strong vacuum to remove the blockage and clear the drain line.

The Air Filter Is Clogged

Most filters last between one and two months, depending on where you live. So, don’t forget to replace the air filter in your air conditioner at least every two months. If you leave the same filter in for an extended period, it’ll become dusty, reducing airflow. Besides putting pressure on your home’s HVAC system, a dirty filter can block the flow of air that passes over the evaporator coil.

When the airflow is interrupted, the air in the evaporator coils gets too cold. As a result, the coils will freeze, causing ice to form on the device and inside. Water drops, and a leak occurs as the ice melts. So, a dirty air filter will make your system work harder, resulting in worn-out parts or possible damage. If you use the AC often, check the filters more frequently to avoid leakage.

Broken Pump or Float Switch

The pumps are required when the home’s drain system is above the air conditioning unit and is situated beneath the cooling coil. The condensation pump’s job is to drain the water to avoid leakage. Water leaking indicated that the pump isn’t working correctly due to dirt and dust accumulation. Even when the drain is clear, water might gather in the pan and flow out if the pump isn’t working appropriately.

First, ensure that the pump is turned on. If that isn’t the issue, the leakage might be caused by a broken pump. If the pump or the float switch malfunctioned, the air conditioner wouldn’t pump water outdoors. As a result, water will accumulate and spill from the AC. You should contact an HVAC company to resolve the issue if that’s the case.

Incorrect Installation

Improperly installed AC can be a reason for water leakage. To prevent this, ensure your air conditioner is fitted with the proper inclination to avoid leaks. The front part of the air conditioner should be colder than the rear part so that the water is adequately drained and won’t leak. In addition, the AC must be installed on an even, flat roof. You can level it by modifying the concrete pad if it isn’t completely smooth.

When using a window AC, raise the unit slightly, so the water drains out the back and outside. Water can leak if the seals that secure the unit to the window aren’t tightened well. When warm air meets cold air, moisture condenses in the AC, which makes a condensation spill. Also, if your device is too flat, water might flow in the wrong direction and invade your property.

Wrapping Up

Once you understand the most common causes of your air conditioner leaking water, you may try to solve the problem yourself if you know what you should look for. If you aren’t sure what the issue is, seek professional help for expert repair. However, you may avoid most of the problems with proper maintenance. Annual check-ups help your AC run optimally, keeping your house pleasant all year.
