Why Is My AC Leaking? Causes and Solutions

Air conditioning units are essential for maintaining a comfortable environment, especially during the hot summer months. However, like any other machine, they can develop problems. One common issue that many homeowners face is a leaking AC unit. But what causes an AC to leak and how can you fix it?

One of the main reasons why your AC might be leaking is due to a clogged drain line. This line removes condensation produced by the evaporator coil during the cooling process. Over time, dust, dirt, mold and other debris can accumulate and block this line leading to water backing up into your home.

Another cause could be a damaged or rusted drain pan which catches water dripping from the evaporator coil. If your ac repair near me unit is older (over 12-15 years), there’s a high chance that the pan has corroded over time causing it to leak.

A dirty air filter could also lead to an AC leakage problem. A clogged filter restricts airflow over the evaporator coil causing it to freeze up when cooling air passes through it too slowly. When this ice melts, excess water may overflow from the drain pan resulting in leakage.

Low refrigerant levels in your AC unit can also cause freezing of its coils which eventually leads to leakage when melted. Apart from leaks, low refrigerant levels will reduce your system’s efficiency and increase energy costs.

Lastly, incorrect installation or poor maintenance might result in a leaking AC unit as well. If it isn’t installed properly with correct levelness or if regular maintenance isn’t done then issues such as blocked filters or drain lines become more likely leading to leaks.

If you suspect that your drainage line is blocked then you should call an HVAC professional who will use specific tools like wet vacuums or specialized blowers to clear out any blockages safely without damaging your system.

For rusty or damaged drain pans, replacing them is the best solution. This should be done by a professional to ensure that it fits correctly and doesn’t cause further issues.

If your air filter is dirty, simply replace it with a new one. Most filters need to be replaced every 1-3 months depending on usage.

In case of low refrigerant levels, you will need an HVAC technician to refill your system as this task requires specialized knowledge and tools.

Finally, ensure that your AC unit is installed correctly and have regular maintenance checks from professionals. This not only prevents leaks but also extends the life of your unit while improving its efficiency.

Remember, if you’re ever unsure or uncomfortable performing these tasks yourself, don’t hesitate to call in a professional. Ignoring or improperly handling a leaking AC can lead to more serious problems down the line including water damage and mold growth in your home.
