Top Reasons Your AC May Be Leaking
Your AC may leak for numerous reasons. The following are a few examples.
Incorrect Installation
A new or replacement air conditioner may leak due to incorrect installation. There are numerous ways an air conditioner can be incorrectly installed. Some of these include, but are not limited to, the following reasons.
- Misalignment or loose connections
- Incorrectly set up condensation drain
- Air conditioning unit isn’t level
- Improper sealing
Condensation Drain Line Clogs
A clogged drain line is one of the most common causes of an air conditioner leak. Mold, dirt, and other substances accumulate in the drain over time, eventually clogging it. Clogs prevent drain lines from working correctly, potentially leading to leaks. When a condensation drain line becomes clogged, it reduces the efficiency of your air conditioner, resulting in higher energy bills.
Condensation Drain Pan is Damaged
A condensation drain pan may rust or develop cracks, potentially resulting in leaks.
Evaporator Coils Freeze
An evaporator coil may freeze, causing an air conditioner to leak. If an evaporator coil freezes, upon thawing, excess water may cause a leak.
The Air Filter is Dirty
A clogged air filter may cause your air conditioning to leak. A clogged air filter may freeze the evaporator coils, potentially causing a leak due to excess water forming when they thaw. This excess water could cause a leak.
The Condensation Pump Breaks
Condensation pumps move condensation to a drain line or outside of a building. If a condensation pump isn’t working properly, it may cause water to overflow from the drain pan.
Refrigerant Levels are Low
Low refrigerant levels can cause an air conditioning leak. When air conditioners have low refrigerant levels, they function with lower pressure, which can cause evaporator coils to freeze. When evaporator coils thaw, excess water can cause leaks. When your air conditioner has low refrigerant levels, it may not cool your home as effectively.
The Air Conditioning Unit is the Wrong Size
For an air conditioning unit to work effectively, it must be the correct size for your home. If an air conditioner is too big or too small for a building, it could leak. If the air conditioning unit is too small, it will most likely need to work harder to cool the building and may not be able to remove condensation. When the air conditioning unit is too big, it may cool the building too quickly, causing it to cycle off before an adequate amount of humidity can be removed. Humidity can cause excess condensation in your air conditioner, potentially leading to a leak.
Air Vents Have an Obstruction
If an air vent is obstructed, it reduces air flow over the evaporator coil. The lack of airflow can prevent the evaporator coil from properly absorbing heat, causing it to become overly cold and resulting in moisture freezing. When the air conditioning shuts off, the evaporator coil will thaw, and the water that forms may flood the drip pan.
Poor Humidity Control
If your home has poor humidity control, it may cause your air conditioner to leak due to excessive moisture.

How to Prevent AC Leaks in Denton, TX
While there are no guarantees, there are several actions you can take to help prevent air conditioning leaks from occurring in your Denton, Texas, home. The following are some actions you can take.
Regular Professional Maintenance
Regular professional maintenance can help prevent conditions that can lead to leaking air conditioners and detect problems before they escalate.
Inspect and Replace Air Filters when Needed
If you know how, you can regularly inspect your air filters and replace them if necessary. This prevents air flow from becoming restricted and causing the evaporator coil to freeze. If you don’t know how to inspect or change your air filters, it will need to be handled by an HVAC professional. Air filters should be changed regularly. Various factors, such as allergies or other medical issues, affect how often the air filters will need to be changed.
Monitor Drain Lines
Regularly monitor your air conditioning’s drain lines to ensure they are not clogged or disconnected.
Check the Condition of your Drain Pan
As cracked or rusty drain pans can lead to leaks, it is important to periodically check your air conditioner’s drain pan.
Watch Refrigerant Levels
Watch your air conditioning’s refrigerant levels; if they are low, contact a professional plumber to conduct an inspection and refill the refrigerant. Please note that refilling refrigerant is a task you should NOT do yourself.
Ensure Air Vents aren’t Blocked
Since blocked air vents can cause water to flood the drain pan, you’ll want to ensure that when it is time to start using your air conditioner, all the air vents are open, unobstructed, and clean.
Control Humidity
If your home suffers from poor humidity control, the excessive moisture that occurs can cause air conditioner leaks.
To control the humidity in your home, you may need to invest in a dehumidifier. Please note that installing a dehumidifier should be handled by a professional.
Get a Condensation Safety Switch
A condensation safety switch powers off your air conditioner if water begins to build up. Please note that this could result in your air conditioning shutting off unexpectedly during hot weather. You’ll want to have your condensation safety switch installed by a professional.
