You can use the following tips to repair it on your own or hire a reliable professional to fix air conditioner leaks. Leaky air conditioners can inflict serious damages to the roofs, walls, and appliances working nearby. Delaying the repairs can cost you hundreds if not thousands of dollars at the best. If you notice a leak, turn off the air conditioner and proceed with repairs.

Replace The Air Filter

The most common cause of leaks in the air conditioner is a clogged air filter. When it’s dirty, the air cannot pass through it effectively. The impeded airflow not only affects the cooling efficiency of the air conditioner but causes the evaporator coils to freeze up. 

Adequate airflow is necessary is absorb heat from the refrigerant passing through the evaporator coils, the lack of it will cause ice formation and water dripping. If you haven’t replaced the air filter for more than 90 days, it’s time to change it. 

Air filters need to be frequently replaced in summers. If you want to avoid such situations, set reminders to check the filter every month.

Blocked Vents

If you have recently replaced the air filter but still facing the issue of leaks near evaporator coils, it’s best to remove blockages from vents. Air vents or registers in the ducts ensure proper airflow. When any of these vents are blocked or covered, evaporator coils can no longer take heat from your home. You will see water dripping from the evaporator coils because of the ice formation. This leads to warm air or no air in your house and puts an unnecessary burden on the compressor. 

Inspect The Drain Pan For Cracks And Overflows

You must learn about the basic parts of the HVAC system before you attempt any DIY fix. The best approach is to consult the users-manual provided by the manufacturer. Locate the air handler which houses the evaporator coil of your HVAC unit. It’s there to catch any condensation flow.

When the unit is turned off, inspect the drain pan and pipes for any leaks. The pipe directs condensate from the drip pan and discharges it outside. You will need a flashlight and a wet-dry vacuum to clean and inspect the bottom and edges of the drain pan. You can fix the cracks with water sealant temporarily but it is recommended to replace the damaged parts.

For most of the units, there are two drain pans. One of them is welded underneath the evaporator coils to catch the condensate whereas the auxiliary one is placed underneath the removable unit. If there are any damages to the permanent, give us a call for quick replacements.

Clear The Clogged Condensate Drain Line

If you have got some vinegar, a wire or a wet-dry vacuum, clearing the clogged condensate drain line is a relatively easy DIY project. Locate the condensate drain line and inspect it for blockages. It can be clogged with fungi, moss, or debris. The drain line should have a cap-topped PVC pipe sticking at a 90o degree angle. 

Unscrew the cap and insert a strong stiff wire in the pipe to get rid of the debris. Or you can about six ounces of white vinegar (acetic acid) down the drain pipe. Cover the pipe again to avoid inhaling any fumes. The acid will hydrolyze the algae, fungi, or other solid debris, freeing up the drain line.

When this fails, you can use a wet-dry vacuum to clear the clogs. Start with the lowest setting and proceed to the highest until the drain line is cleared. You will need a wet-dry attachment for this project which is easily available at home improvement stores.

Refrigerant Leaks

Although not very common, refrigerant leaks are possible. If your HVAC system is low on refrigerant, supply vents blow warm air, electric bills are higher than normal and you may see ice around the outdoor condenser unit. Any of these signs necessitate hiring an experienced HVAC technician.
