Suppose you wander around your home and observe that your AC is leaking. In that case, you should contact AC repair services and tell them about your situation. A simple leak can indicate some serious damage, or it might be a mechanical problem related to a lack of maintenance.

For example, you might have debris or dirt causing some blockage. Nonetheless, before you call in the professionals, there are some things that you should do first, such as:

Turn Off Your AC Unit

Turning off your AC unit might prevent the leakage from expanding, but it will also allow you to inspect it closer and see what is wrong in a safe manner. You shouldn’t approach your unit until it is turned off completely.

Clean the Water Spill and Inspect the Unit

Clean up the water before you start inspecting your unit, and try to determine where it comes from. This might later help you when you talk to the technician, but it will also help you avoid slips or doing further damage to the surrounding area.

You shouldn’t try to repair the unit by yourself because you might damage it further or hurt yourself in the process. Also, you might void your warranty by doing so. However, there are some things that you can do without voiding your warranty, such as:
 

Checking the Air Filters

Leaks can occur for various reasons, but among the most common is an obstruction of airflow that slows down the heat transfer. In general, air filters need to be replaced every one to three months, and if you fail to do so, your unit can accumulate dust and debris.

If indeed you haven’t changed the air filters for a long time, it might lead to leakage issues because your evaporator coil couldn’t function properly because of airflow obstruction. If this is the case, replacing your air filters might not be enough to fix the issue, but if you are lucky enough, it might.

Inspect Refrigerant Levels

Clogged air filters can make your evaporator coil freeze, but so too will low refrigerant levels. When the evaporator coils freeze, it can drip water into the drain pan, which in time, can overwhelm it and lead to leaking.

You should check your refrigerant levels and keep track of them. They shouldn’t be low enough for your coil to freeze. 

Check if Drain Pan Is Clogged

Sometimes, your AC’s drain pan or pipe can clog due to dust, mold, dirt, or debris. In time, it can result in leakages as well. You should inspect your drain pan before calling in a technician.

Remove any debris from the base of the air handler or check to see if there is a blockage outside. In some instances, you might not be able to clean the drain pipe completely, but you can call a technician to help you with this as well.

Call an HVAC Technician

Once you are done checking your AC for the simplest issues that usually lead to leakages and determine that sometimes else is at fault, it’s time to call in the big guns. An HVAC technician can accurately determine the cause of your leakage and help you bring your AC back to normal.

Until the technician comes, you shouldn’t use your AC any further. The best thing to do is to keep it off and wait for the professionals to arrive. If you leave your AC on, you might make the leakage worse or further damage your AC unit. Contact your local HVAC technician and tell them about your issues immediately. Don’t consider the leakage minor because it might hide something worse.
