Air conditioning systems are designed to keep your home comfortable by regulating temperature and humidity levels. However, when your AC starts leaking water, it can be a sign of a problem that needs attention. Today, we at Absolute P&M Services would like to offer a guide on what to do if you notice water leaking from your air conditioner.
Turn Off AC Unit
Firstly, for safety reasons, turn off your AC unit. Water and electricity don’t mix, and continuing to run your air conditioner while it’s leaking can cause damage to the system and pose a safety hazard. Locate the thermostat and switch the unit off to prevent any further issues.
Check AC Drain Pan
The next step is to inspect the drain pan. The drain pan is located directly under the evaporator coils and is designed to catch any condensation that drips from the coils. Over time, the drain pan can become damaged or rusted, leading to leaks. Use a flashlight to check for any visible cracks or holes. If the drain pan is damaged, it will need to be replaced.
Clear AC Condensate Drain Line
One of the most common reasons for an AC to leak water is a clogged condensate drain line. The condensate drain line carries excess moisture from the unit to the outside of your home. If it becomes clogged with dirt, dust, or mold, the water backs up and can overflow. To clear the line, use a wet/dry vacuum to suck out any debris. Alternatively, you can use a plumber’s snake or a long brush to remove the blockage. After clearing the line, flush it with a mixture of bleach and water to kill any remaining mold or algae.
Replace Air Filters
Dirty or clogged air filters can restrict airflow over the evaporator coils, causing them to freeze and eventually melt, resulting in excess water that the drain pan may not be able to handle. Check your air filters and replace them if they’re dirty. It’s a good practice to replace or clean your air filters every one to three months, depending on usage.
Inspect AC Evaporator Coils
Frozen evaporator coils can also cause water leaks when they thaw. If you notice ice buildup on the coils, turn off the AC and let the ice melt completely. This can take several hours. Ensure the coils are clean and free of dust and debris. If the coils are dirty, clean them with a soft brush or a coil cleaner.
Ensure Proper AC Installation
Improper installation can sometimes lead to water leaks. Check if the unit is level. If it’s tilted, water may not drain properly. Ensure the AC is installed correctly according to the manufacturer’s specifications.
Call a Professional AC Contractor
If you’ve checked all the above steps and your AC is still leaking water, it’s time to call a professional HVAC technician. There could be a more complex issue that requires expert diagnosis and repair. Professional technicians have the tools and experience to identify and fix problems that aren’t easily visible to the average homeowner.
