The greatest reason for water leakage in your AC unit is a dirty filter. It’s essential to change the air filter every 30 days. Howerver, air filters with dirt and dust create problems and make your AC unit work harder. So, it leads to system failure or damaging its internal parts.

A dirty filter also causes strain in AC units and blocks the free flow of air through evaporator coils. In the absence of free flow of air, the coil starts freezing and becomes extremely cold. When the coils melt, they results in water leakage.

Solution – Always check your air filter from time to time and change the air filter every one to two months. In case, the filter looks dirty, clean it, and you can call a professional team to help you out with the leakage problem.

The drain line disconnected may be because of improper installation, irregular maintenance, ineffective repairing services, and sometimes it loses down because of long use. Hence, in case of disconnection of the drain line, the water starts flowing on the floor or leak through the ceiling. The location of leakage depends upon the area in which your air conditioner unit is installed.

When you install new AC, and frequently, it starts leaking water, you may get perplexed. The reason behind the leaking is the improper installation of the AC unit. The drain pipe and AC should be installed proportionally. When they are not proportional, the water doesn’t flow properly from the drain pan, causing leakage of water from AC unit.

The air filter filters the pollutants present in the air and also allows the free flow of fresh air into the home. But sometimes, the dirt and debris accumulate and block the filter and create problems in the AC unit. It also affects the indoor quality of air supplied by AC units.

Solution – First, find out the place from where the water is dripping. Protect your wall and ceiling from getting damaged. Right after that, make sure to clean your filter properly and fix it back to AC unit once it dries up completely. It’s also essential to frequently clean your AC unit to avoid the blockage of the air filter.

One of the reasons behind the AC unit water leakage problem is refrigerant. In the air conditioner unit, refrigerant is located inside it. It is responsible for circulating until the lifespan of your AC unit. In case the refrigerant is low, it results in icing up the evaporator coil because pressurization in the pipelines is improper. When the frozen evaporator coil starts melting, the drain pan starts leaking water and causes the air conditioner to leak water.

Solution – To prevent your air conditioner from this type of leakage, call a professional AC maintenance service provider in Eastvale. They offer effective services to their customers. They solve all ac leakage issues quickly.

6. The Problem In Condensate Drain Line

The problem in condensate drain line gives birth to water leakage problems. At the time of the dehumidification process, the air conditioner collects moisture along with debris and dirt. In case the homeowner neglects to clean the condensate drain line, the dirt and debris accumulate and become the main reason for blockages. Due to that, water gets collected to the drain line and drips out from your unit. Nowadays, many AC units come with an auto switch off the system. This system automatically detects the accumulated dirt and debris in the condensate line. It helps in protecting your home from AC leakage problems.

Solution – Just locate the drain line and, with the help of a brush or scrub, clean the debris and dirt. If the clogging is severe, you can also use a vacuum cleaner to clear the junk deeply. Calling a professional AC repairing service provider is also a good option for preventing your AC unit from water leakage.

In the air conditioner unit, underneath the cooling coil, a condensation pump is located. The function of this condensation coil is to prevent water leakage from the air conditioner unit and drain out water. But sometimes, due to the accumulation of debris and dirt particles, the condensation pump either stops working or starts malfunctioning. This causes water dripping problems in the air conditioner and also the indication that some damage has taken place in the condensation pump.

Solution – It’s essential to clear the condensation pump for proper flow of water. Calling an expert is the best option one can have.
