Air conditioning is a crucial part of staying comfortable during hot Texas summers, especially in areas like Richardson, Allen, and Frisco. But when you notice water leaking from your A/C unit, it can be alarming. A water leak may seem like a small issue, but if left untreated, it can cause major damage to your home and lead to costly repairs. Understanding why your A/C is leaking and how to fix it is key to preventing further issues.
If you’re dealing with a leak from your air conditioning unit in Plano or North Dallas, this guide will help you identify common causes and provide actionable solutions.
Key Takeaway: Water leaking from your A/C is often caused by a clogged drain line, frozen evaporator coils, or improper installation. Fixing these issues promptly will help avoid damage and maintain the efficiency of your cooling system.
Common Causes of A/C Water Leaks
Clogged Drain Line
When your air conditioning unit cools the air in your home, it also removes moisture. This moisture is collected in a drip pan and drained outside through a condensate drain line. If this line becomes clogged with dirt, mold, or debris, water can back up and leak into your home.
Frozen Evaporator Coils
A frozen evaporator coil can also be a culprit. If the coils inside your unit freeze, it can prevent proper airflow, leading to condensation buildup that eventually leaks out. Several factors can cause frozen coils, including low refrigerant levels and restricted airflow due to a dirty air filter.
Improper Installation
Improperly installed air conditioning units may have drainage issues. If your system is not level or the drain pan is misaligned, water can overflow from the pan and leak into your home.
How to Fix a Water Leak from Your A/C
Clearing the Drain Line
To clear a clogged drain line, start by turning off your A/C unit. Locate the drain line (typically a PVC pipe) and use a wet/dry vacuum to suck out the clog. Regular maintenance, including cleaning the drain line, can prevent future clogs. You can also add a small amount of bleach or vinegar to the line to kill mold and algae that can cause blockages.
Addressing Frozen Evaporator Coils
If you suspect your evaporator coils are frozen, turn off the A/C and allow the ice to thaw. Replace dirty air filters regularly to ensure proper airflow, and check refrigerant levels to maintain efficiency. If the problem persists, you may need to contact a professional for leak detection and repair, especially in areas like Addison or Lake Highland.
Correcting Installation Issues
If improper installation is causing water leaks, you’ll need a trained technician to inspect and correct the problem. Ensuring your unit is level and the drain pan is positioned correctly will resolve drainage issues. Casto Leak Detection can help identify installation errors and offer reliable solutions.

Preventing Future A/C Water Leaks
Regular Maintenance
Preventative maintenance is essential to keep your A/C running efficiently and prevent leaks. Schedule yearly inspections, clean the coils and air filters, and check the drain line for clogs.
Replacing Old Units
Older air conditioning units may be more prone to leaks due to wear and tear. If your A/C is over ten years old, consider replacing it with a new, energy-efficient model to prevent frequent breakdowns and leaks.
Monitoring Your Unit
Keep an eye on your A/C during peak use in the summer months. If you notice water pooling near the unit, investigate immediately. Early detection of leaks can save you from costly water damage and repairs.
Answering Common Questions
